366 L COLEOPTERA 



NOTE. The genus Prioscelida, White (Voy. Er. Terr., Ins., p. nj, 

 judging from his descriptions, generic and specific, appears to me to 

 be but another name for Uloma. I have carefully examined what I 

 believe to be his Prioscelida tenebrionoides, but have failed to detect any 

 characters that would justify the retention of his genus. 



663. U. (Prioscelida) tenebripnoides, White; Voy. Er. 



Terr., Ins., p. n. Body moderately shining piceous, with the under- 

 side paler, and the legs, antennae, and palpi reddish. The antenna 

 have a stout basal joint, the second is about as large as the fourth, third 

 moderately elongate, joints four to six about equal, the latter a little 

 larger than the fifth ; seven to ten transverse, considerably larger than 

 their predecessors ; eleventh transverse but rounded, and the last seven 

 with yellow pubescence, and loosely articulated. Head short and broad, 

 rounded, with the epistome slightly emarginated in front, and, in the 

 males, with two or more rounded elevations ; there is a transverse im- 

 pression behind the eyes ; the surface, except near the eyes, is quite 

 impunctate, but in the females the head is punctulated throughout. The 

 prothorax is subconical, moderately convex, rounded anteriorly, with 

 the lateral rims somewhat thickened near the base ; its surface is punc- 

 tulated, and there are some more or less distinct depressions along the 

 base ; in the males it is broader, and has a rounded depression in front. 

 Scutellum finely punctulated. Elytra oblong, transversely convex, their 

 shoulders prominent, sides margined, nearly parallel, yet a little widened 

 posteriorly ; each bears a scutellar, and eight not very strongly punctured 

 striae, the marginal is abbreviated, the second to seventh are united 

 posteriorly in pairs, and the interstices are nearly plane. 



The anterior tibia are comparatively slender at the base, and from 

 thence curved and dilated, and armed externally with a row of short 

 teeth, variable in number and development even in the same sex ; the 

 intermediate bear a double row of smaller teeth, and the posterior are 

 simple. The basal and apical joints of the hind tarsi are elongate and 

 about equal, the second and third are short and nearly alike. The 

 breast is more or less punctured, and the abdomen somewhat rugulose 

 longitudinally. 



Length, 6 ; breadth, 2\ lines. 



The above description of insects in my collection, obtained in several 

 different localities, corresponds with White's Prioscelida tenebrionoides, 

 and the Uloma nitens of Redtenbacher. I have discarded White's 

 generic name, but retained the specific one, and this, I hope, will end 

 the confusion that has hitherto existed. 



Apthora. 



Bates. 



Body oblong, transversely convex ; head rounded, immersed up to 

 the eyes ; labrum transverse, slightly rounded in front; last joint of 

 maxillary palpi securiform ; eyes transverse, moderately facetted. 

 Antenna robust, inserted in large cavities at the sides in front of the
