Page 461 - Elytra ample, sometimes almost ventricose, deeply striate, entirely covering the pygidium ; without epipleura; fold on the inner surface parallel with the side margin, diverging gradually from it towards the tip. Wings large. Abdomen with the first and second ventral segments large, closely connate, with a fine straight suture; third and fourth segments very short, sutures straight; fifth longer, flat, rounded at tip ; dorsal segments membranous, pygidium small ; anterior coxae conical, prominent,...
Page 426 - Antennas inserted at the sides of the beak, in position varying according to the genus; 11-jointed straight, first joint not elongated, and scarcely stouter, 2-8 slender, 9-11 broader, forming a loose club, and covered with sensitive surface. Head prominent, not dcflexed, eyes rounded finely granulated; beak slender, varying somewhat inform according to the genus.
Page 511 - ... compressed, toothed, or with transverse ridges on the outer side rarely simple (Micraces) ; armed with a terminal hook at the inner apical angle. Tarsi in some genera filiform and 5-jointed; in others 4-jointed, with the third joint either narrow or dilated and bilobed; last joint long, with large, simple, divergent claws. The insects of this family are mostly of cylindrical form and small size. They are the most formidable enemies of trees, sometimes devastating the forests, especially of conifers,...
Page 484 - This tribe contains a large number of genera, which differ so much in appearance and details of structure, that scarcely anything can be predicated of all. It may, however, be stated in general terms, that while in common with several other tribes, the beak is received upon the sternum, and lies in repose in a pectoral groove, this tribe differs from Zygopini in the smaller size and different position of the eyes, which are more or less covered by the prothoracic lobes ; and from Ceutorhynchini by...
Page 440 - In all the species the ocular lobes are of moderate size and fimbriate. The surface of the body is densely scaly and without any pubescence. Two genera appear to be indicated in our fauna: — Tarsi slender, third joint not wider than second, and simply emarginate : sides of thorax with tuberosities more or less marked ; tips of tarsal joints beneath spiniform.
Page 429 - Elytra not covering the pygidium, separately rounded at tip; epipleurac narrow but distinct; inner surface without lateral fold. Abdomen with five short ventral segments separated by deeply impressed straight sutures, intercoxal process acute; fifth at the middle very short, being compressed by the inflexion of the pygidium; side margin not acute nor extended upwards. Dorsal segments convex, almost corneous. Pygidium small corneous, upper margin with a large deep marginal groove. Anterior coxae conical,...
Page 421 - Maxillae with prominent base, and two lobes, which are connate at base, the inner one sometimes atrophied ; maxillary palpi 4-jointed, not dilated. Head vertical, affixed to the prothorax by a very slender neck, which is entirely contained in the prothorax ; vertex usually elevated ; eyes large, very finely granulated, except in the first tribe ; mandibles not emarginate at tip, entirely corneous, without any membranous border on the inner margin ; labrum prominent.
Page 496 - ... it is frequently twice the length, and is used to make the perforation into which the egg is subsequently introduced. The great thickness of the husks of the fruits (chestnuts, walnuts, hickory-nuts, etc.), depredated on by these insects, necessitates a very Ion? perforating instrument to reach the kernel, upon which the larva feeds.
Page 428 - A single species constitutes this sub-family On account of the anomalous characters its place in the series of Rhynchophora has been changed from time to time, without very satisfactory results. The latest authority, Lacordaire, deceived by the broad form of body and ascending side pieces of the mesothorax, placed it in the neighborhood of Ceutorhynchus. A study of the mouth organs, as well as the...
