Coleopterological Notices, IV. C87 



from Texas (Austin) and Florida give the following dimensions. 

 Length 3.2-3.4 mm. ; width 1.1-1.25 mm. 



Another variety is represented before me by two specimens from 

 Guerrero, Mexico, which are of about the same size as zea-mais, 

 but more coarsely and densely punctate, and more opaque, with the 

 elytral punctures more quadrate. 



C. rugicollis n. sp. — Oval, moderately stout, rather flattened above, 

 dull, very sparsely clothed with short erect yellowish setse, forming single 

 series on the alternate elytral intervals. Head deeply but not coarsely, 

 rather sparsely punctate, with a large deep fovea between the eyes ; beak 

 in the female slender, feebly arcuate, smooth, minutely sparsely and sub- 

 seriately punctate, fully as long as the prothorax, abruptly and angularly 

 dilated, duller and coarsely, seriately punctate near the base ; antennse in- 

 serted at basal sixth, slender, the second funicular joint obconical and one- 

 half longer than the third. Prothorax barely as long as wide, the sides rather 

 strongly convergent from near the base, rounded at base, deeply, tubularly 

 constricted at apex, the latter fully one-half as wide as the base ; disk deeply, 

 rugosely punctate. Scutellum dull, impressed. Elijtra at the humeri exactly 

 equal in width to the disk of the prothorax, two-fifths longer, the sides strongly 

 convergent throughout and nearly straight ; apex conjointly rather narrowly 

 rounded ; disk with contiguous series of very coarse, quadrate, closely crowded 

 punctures, alternately separated by narrow flat intervals, each of which is 

 coarsely, uniseriately punctate, the punctures oval and almost contiguous. 

 Pygidiuin and under surface coarsely deeply and densely punctate. Length 

 4.0 mm. ; width 1.5 mm. 



Florida. 



A single specimen, taken b}- Mr. F. Kinzel in the southern part 

 of the State and presented to me by Mr. W. Jiiiich. This species 

 is undoubtedly allied to the African rugonirf; Thunb,, but differs 

 according to the description of ScLo.iherr, in its much shorter, non- 

 canaliculate prothorax, and its more strongly and closely punctate 

 abdomen. Riigicollis is brownish-black in color, the elytra each 

 clouded feebly with rufous along the middle. The base of the pro- 

 thorax is transverse and perfectly straight. In riu/ot^ns the pro- 

 thorax is said to be one-half longer than its basal width. 



Rhinin^. 



YUCCABORUS Lee. 



This singular genus is unmistakably allied to Rhina, being in 

 fact nearly identical in rostral structure, but differs in many impor- 

 tant features, among which may be mentioned the widely separated
