 jince of sboit elytra; a tliird and fourth specimen are still more frag- 

 mentary. The snout is shaped much as in Otiorliynchiis peyditus Scudd., 

 being short, stout, and, especially anteriorly, arched, the front border being 

 faintly angulate about the middle ; the antenual scrobes cannot be cer- 

 tainly defined ; the eyes are pretty large, transversely ovate, and are, in 

 most of the specimens, indicated on the stone by an annulus of dark 

 color, containing an interior narrow ovate pale spot .22"'-" long by .12""" 

 wide; while the eye itself is .4™'" in its longer and .3'"™ in its shorter 

 diameter ; the facets of the interior portion are very minute, being 

 scarcely .01"'"' in diameter. The prothoras is somewhat tumid, rather 

 higher than long, very profusely and delicately punctulate, the anterior 

 and posterior walls between the pittings often less elevated than the 

 lateral walls, so that the punctures often form broken longitudinal fur-* 

 rows ; the punctures are nearly uniform in size over the whole prothorax 

 and average about .04 "'"^ in diameter. The elytra are simple, not tumid, 

 sloping off gradually toward the tip, not elevated at base above the 

 thorax, and provided with six equidistant, very slender and slight, 

 raised ridges, faintly broken into dashes by a series of minute, moder- 

 ately distant jDunctures along the inner border of each ; these punctures 

 are of the same size as those on the prothorax ; the ridges are about .16""" 

 apart. The posterior cox?e have an incrassate posterior margin. 



Length of body, 4""" ; of rostrum beyond the eye, .68™" ; width of 

 vsame, .46"'"^; length of prothorax, 1.2""'; height of same, 1.'3"""; length 

 of tegmina, 2.8"™; width of same, .9""". 



25. Eudiagogus examinis. — A. considerable number of specimens of 

 this insect were obtained by Mr. Ifichardson with the preceding species. 

 All were fragmentary, and most of them rather obscure; they consist 

 mostlj^ of side aspects of the creature, but several are single elytra. 

 The head is rather large at base, tapering, with a short, broad snout, 

 not so deep as broad, equal and at the tip broadly rounded, directed 

 downward and forward, slightly bent along the front margin; the auten- 

 nal scrobes extend from the front edge of the eye nearly to the end of 

 the rostrum, and are broadest next the eye, where they are half as broad 

 as the eye itself, tapering regularly throughout and shallow ; the eyes 

 are moderately large, broadly oval, transverse or a little oblique, the 

 upper extremity thrown backward and the lower forward. The protho- 

 rax is short, only about half as long as deep, not tumid, rather cylin- 

 drical, its surface smooth. The elytra are not broader nor higher at 

 their base than the surface of the pronotum, and they are simple and 

 furnished with seven equidistant, equally and not deejily impressed, 

 longitudinal strife, .16""" apart from one another, and the outer ones from 

 the adjacent border; these striae are provided with slightly longitudi- 

 nal punctures at regular intervals of about .1"'", by which the strioe are 

 carried to about double their usual depth. Some of the specimens have 

 lost the elytra, and on these the posterior edge of the hind coxa? have 

 been impressed through the abdomen, giving the insects the appearance 

 of being furnished with elytra which cover but half of the abdomen. 

 The same thing was noticed in other species. 



Length of body, exclusive of rostrum, 5.75""' : of rostrum beyond the 

 eye, .62"'™ ; breadth of same, .5""" ; depth of same, .44"'" ; length of eye, 

 .36"'"'; width of same, .24"'"'; length of prothorax, .72"""; height "'of 

 same, LS"" ; length of elytra, 3.05'""' ; width of same, 1.2"'" ; length of 

 fore femora, .72'""' ; width of same, .32" '" ; length of middle femora, 

 .8"'"'; width of same, .32"""; length of hind femora, 1.1"'" : width of 

 same, .34'""'. 



26. Eudiagogus efbssus. — This species is represented by a number of 

 fragments brought by ^Mr. Richardson from the same place as the pre-
