ceding species. They are mostly composed of fragments of elytra, and 

 the only specimens which are preserved entire are such as give a dorsal 

 or ventral aspect. These, however, are enough to show that they belong 

 to a species closely allied to but distinct from the preceding, from which 

 it differs i^riDcipally in its smaller size, its slenderer and more tapering 

 rostrum, the smaller circular eyes, and in the slightly more distantand 

 rather more deeply impressed strife of the elytra. The following meas- 

 urements will give a better understanding of the degree of difference 

 between them in certain points. 



Length of body, exclusive of rostrum, 5"™ ; breadth of same, 2.1""™ ; 

 width of rostrum at base, .48"™ ; diameter of eyes, .28"™ ; distance apart 

 of the elytral stride, .18-.20™'" ; distance apart of punctures in the strife,

27. HyloMiis provectiis. — A single specimen was found by Mr. Eichfard- 

 son with the preceding species. It is very poorly preserved, being not 

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

 its length cannot be determined, but the general facies of the insect re- 

 sembles that of S. ])icivorus Germ, so closely that it must be referred 

 to the same genus. The rostrum is rather stout ; the antennal 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 

 Eudiagogus saxatilis Scudd., with very small facets, scarcely .02''™ in 

 diameter. The thorax is rather small, but apparently partially con- 

 cealed 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 

 oi Eudiagogus just described, provided with slender, shallow, impressed 

 lines, about .22'""^ apart ; the hitter are rather delicately punctured, the 

 punctures a little less distant from one another than are the rows ; the 

 number of rows cannot be determined from this specimen. 



Length, exclusive of rostrum, 5"'"; length of broken rostrum, .45™"'; 

 of eyes, .9™"' ; breadth of same, .44™™ ; length of elytra, 4™'". 



28. Anthonomus defossus. — A single well-preserved specimen, present- 

 ing a side aspect, was obtained by Mr. T. L. Mead near Castello's ranch. 

 South Park, Colorado. It is nearly as large as A. hcematojnis Boh., with 

 a slightly more curved rostrum, slightly transverse eyes, and with more 

 abundant pitting of the prothorax, which is also less obscured by hairs. 

 The head is smooth, covered very sparsely with very fine, short, almost 

 invisible hairs, directed downward : the antennal scrobes appear to be 

 rather shallow. The prothorax is covered with exactly similar hairs, 

 very distant, apparently arising only on the sharp ridges between the 

 pits with which the surface is completely studded ; these pits are rather 

 deep, rounded, about .032^^ in diameter, and as closely crowded as pos- 

 sible; the thoracic pleura are similarly pitted, but with a little less 

 frequency, and therefore with coarser bounding walls. The elytra are 

 coarsely ridged with nine equidistant, stout, rounded costfe, .1™°" apart, 

 the fourth from the outer border terminating between the conjoined 

 apices of those on either side of it ; they are rather more prominent and 

 more distant than in A. hcemato}) us ; the whole surface of the elytra, 

 both costfe and furrows, is dull rugulose. The legs are similar to those 

 of the living species mentioned, but are somewhat shorter. 



Length from front of head to tip of elytra, 2.2™™; length of rostrum, 

 .88™™; width of same, .11™™; length of prothorax, .54™™; o^ middle 

 femora, .72™™ ; breadth of middle femora, .17™™ ; length of eye, .18" 

 breadth of same, .14™™. 



29. Cryptorhynclms annosus. — A single specimen was found by Mr 

 Eichardson beyond the Green Elver crossing of the Union Pacific Eail 

 road. The fragmentary specimen is exposed on a side view, with head
