414 APPENDIX. 



[LeOonte. 



neled, but flat, or even feebly concave longitudinally ; lateral grooves in 

 front of the eyes triangular, feeble, short. Prothorax rounded on the sides, 

 not constricted at tip, convex finely and densely punctured, with a very 

 faint narrow dorsal line, with a paler lateral stripe, as in T. simplex. Elytra 

 densely and finely punctured, without strias, but tesselated in the usual 

 manner with darker spots. Length 8.6 mm.; .33 inch. 



Colorado ; one specimen kindly sent to me by Prof. F H. Snow, by whom 

 it was collected while in charge of the Kansas University Scientific Expe- 

 dition of 1876. TJiis species exactly resembles T. simplex, except in the 

 absence of the well marked medial groove on the upper surface of the 

 beak. 



p. 124, to end of table of Phytonomus add in 5: 

 Scales golden-yellow, elytra with conspicuous black spots, 



sides of prothorax rounded exiraius. 



4-5. Phytonomus exiraius, n. sp. 



Of the same size and form as P. comptus, black, prothorax and elytra 

 densely clothed with golden yellow scales, elytra with many small quad- 

 rate spots of black scales. Head and beak densely punctured, scales dense 

 upon the occiput, gradually thinner in front, so that the beak becomes free 

 from scales, but sparsely pilose with long bristles ; frontal groove very 

 short between the eyes, which are not prominent. 



Prothorax as long as wide, truncate at tip, broadly rounded at base, 

 sides parallel for half the length, then obliquelj'^ narrowed to the tip, which 

 is impressed on the sides, but not on the upper surface ; there are two ill- 

 defined approximate basal black spots. Scutellum yellow, scaly. Elytra 

 fully one-half wider than the prothorax, humeri oblique, obtusely angu- 

 lated ; sides parallel for two-thirds the length, then obliquely rounded to 

 the tip ; striae fine, well marked, distinctly punctured, interspaces flat, with- 

 out rows of bristles, under surface covered with paler scales, legs black, 

 thinly clothed with pale hairs, thighs with a spot of pale scales. The an- 

 tennaj are black and extend to the base of the prothorax ; the first 

 joint of funicle large, conical, as long as the three following united ; 2-7 

 equal in length, but increasing rapidly in breadth, and united not longer 

 than the club, which is elongate-oval and pointed at tip. Length 4.5 mm. ; 

 .18 inch. 



Topeka, Kansas ; Mr. E A. Popenoe. I have seen two specimens of this 

 very prett)^ species, one of which has been kindly placed in my collection. 

 It diff'ers from P. c&mpfus not onlj^ by the color but by the first joint of the 

 funicle being large and the second not longer than the following; the funicle 

 is also thicker and the club larger than in that species. 



The scales in this species are deeply cleft almost to the base. Since the 

 printing ot that part of this memoir which relates to the present genus, I 

 have examined more closely the scales of the difierent species in our fauna 

 with the following result : 



A. Scales thick, truncate, or very feebly emarginate at tip, with the an- 

 gles not prominent.
