nished with a imuiber of sliglit, slender, raised ridges, 0.34"'" apart, which 

 are probably the reverses of strite. In general form, the insect appears 

 to have closely resembled Eudiagogus examinis Scudd., but differs from it 

 conspicuously by its longitudinal eye. Dr. Le Conte has suggested to 

 me that it may be an Anthrihide, near Cratoparis. 



22. Otiorliynclms jyerdUus. — A single specimen, showing a side aspect, 

 ■was obtained by Mr. Eichardson at the same locality as the last. It 

 differs from the species of Otiorhynclms, with which I have compared it, 

 in not having the prothorax conspicuously smaller than the body behind 

 it. The head is withdrawn into the prothorax, almost to the hinder 

 edge of the eyes; the snout is short, stout, slightly curved, bluntly 



.rounded and rather tapering than enlarged at the tip, not quite so long 

 '{measuring from the front edge of the eyes) as the length of the pro- 

 notum; the eyes are rounded, subtriangular, with a diameter equal to 

 half the width of the snout, the central facets with a diameter of 0.027""" ; 

 the antennal scrobes are twice as long as broad, commencing at the 

 middle of the snout and extending two-thirds the distance thence to its 

 tip. The prothorax is equal, nearly as long as high, not tumid, rugulose. 

 The elytra, which are not elevated at base above the prothorax, are sim- 

 ple, not very tumid, provided with about eight longitudinal slender 

 rows, .3""" apart, of low, raised, rounded points, nearly as distant from 

 one another as those of contiguous rows ; midway between each 

 of these rows is a very inconspicuous dull ridge. Fragments of the legs 

 remain, which agree, as far as they can be made out, with the same parts 

 in OtiorhyncJius. In the general sculpturing of the elytra this insect is 

 not very unlike 0. sulcatus (Fabr.)

23. Eniimus primordialis. — A single specimen, found by Professor 

 Denton, at Chagrin Yalley, White Eiver, represents this species. Be- 

 sides a crushed elytron there are only some indeterminate fragments 

 of the neighboring parts of the body. The form and sculpturing of the 

 elytron resemble those of the Brazilian diamond-beetle so closely that I 

 place the species provisionally in the same genus, or until further re- 

 mains are obtained. The insect must have been rather small for an 

 Etitimus, although it is the largest of American Tertiary GurcuUonidce 

 known to me. It is of about the usual size of the species of Otiorhynchus, 

 and it is not at all improbable that it should be referred to the latter 

 genus, some species of which have elytra with similar sculpturing and 

 approximately the same form. The elytron is traversed by ten similar 

 stout and coarse, longitudinal cost^e, most of which are broken uj) by 

 transverse depressions into bead-like hemispherical prominences ; at 

 the tip of the elytron, however, and on the apical half of the inner 

 two costfe, this irregularity is nearly or quite lost sight of; the edges 

 of the elytron, for about the width of one of the costse, is also smooth and 

 depressed ; the front border is sinuous, and the sutural margin appears 

 the same on the stone, from the compression the elytron has undergone, 

 which was sufficient to split it down the middle through half its length. 



Length of fragment, 8""; greatest breadth of un split portion, 4"". 



24. Eudiagogus saxatilis. — ^Four specimens were obtained by Mr. Eich- 

 ardson beyond the Green Eiver on the Union Pacific Eailroad, Wyoming. 

 One of these represents a nearly complete side view of the insect with- 

 out other appendages than the elytra ; another i)resents a similar appear- 

 ance, but even the elytra are gone, and the hinder edges of the poste- 

 rior coxse are impressed upon the superior surface, giving the appear-
