uess. Tlie specimoiis of A. defossus examined give, however, a lateral view 

 and rendei comparison somewhat difficuU. 



Green River, Wyoming. One specimen, No. 48 (Prof. L. A. Lee). 



HYLOBIUS Germar. 

 Hylobius provectus. 



PI. 8, Figs. 37, 41. 

 Hylohius provectus Scudd., Bull. U. S. Gcol. Geogr. Siirv. Terr., II, 8G (1876); IV, 767 (1878). 



The single specimen first found is very poorly preserved, being not 

 only fragmentarv but faintly impressed; the rostrum is broken, so that its 

 length can not be determined, but the general facies of the insect resembles 

 that of H. picivorus Germ, so closely that it must be referred to the same 

 genus. The rostrum is rather stout ; the aritennal scrobes are slender, and 

 commence not far beyond the eyes ; the eyes are very large, transverse 

 obovate, with an interior clear space, as described in Epicferus saxatilis 

 Scudd., with very small facets, scarcely 0.02°"" in diameter. The thorax is 

 rather small, but apparently partially concealed by the way the specimen is 

 crushed, not very tumid, and entirely smooth. The elytra are of much the 

 same form as those of the species of Ejjiccierus just mentioned, provided 

 with slender, shallow, imj)ressed lines, about 0.22""" apart ; the latter are 

 rather delicately punctured, the punctures a little less distant from one 

 another than are the rows; the number of rows can not be determined from 

 this specimen. 



Length, exclusive of rostrum, .5'"" ; length of broken rostrum, 0.45""" ; 

 of eyes, 0.9""" ; breadth of same, 0.44""™ ; length of elytra, 4"". 



Another specimen, taken by Mr. Bowditch at the same locality as tlie 

 other, shows the character of the rostrum. The specimen is strangely pre- 

 served, as there appears to be a second rostrum, a perfect counterpart of 

 the first, attached to it at the tip; perhaps this belongs to another indi- 

 vidual, of which the rostrum only is preserved. The rostrum is about as 

 long as the thorax, scarcely tapering as viewed laterally, gently curved, 

 with a median, lateral, longitudinal groove, directed toward tiie middle of 

 the eye, just as in H. confusus Kirb., besides the antennal scrobes, which 

 are directed obliquely toward its base.
