APHA^OTUS Lee. 



The two species of this genus difFer by characters which in many 

 parts of the family might readily be considered generic, but in this 

 instance I do not think that they possess more than a specific value, 

 because of the general resemblance throughout the remainder of the 

 body, which is so marked that without close examination they 

 might possibl}^ be confounded. The differences may be expressed 

 as follows : — 



Eyes completely divided ; last joint of maxillary palpi rounded at apex and 

 scarcely perceptibly oblique ; antennse gradually strongly dilated toward 

 apex, the outer joints compactly joined, the eleventh transversely truncate 

 throughout tlie width and much wider than long Ijrevicornis 



Eyes not completely divided ; last joint of maxillary palpi truncate at apex, 

 the truncation strongly oblique ; antennae rather less strongly dilated 

 toward apex, the outer joints widely separated and i^erfoliate, eleventh 

 slightly wider than long, oval, the apex strongly rounded throughout the 

 width and with a large sensitive area '. parallellis 



In general habitus, the two species can be distinguished by the 

 more elongate elytra of parallelus. 



A. parallelus n. sp. — Elongate, parallel, moderately convex, rufo-casta- 

 neous throughout, strongly shining, glabrous although each puncture has an 

 excessively minute erect seta. Head about two-thirds as wide as the pro- 

 thorax, slightly transverse, vertex rather convex, finely, densely punctate ; 

 epistoma subtruncate ; eyes large, the dorsal portion oblique and gradually 

 acuminate ; antennae with the tliird joint slightly longer than wide and dis- 

 tinctly longer than the second or fourth, the latter equal. Prothorax scarcely 

 one-third wider than long ; sides nearly parallel, evenly and rather feebly 

 arcuate; apex just visibly narrower than the base, broadly, feebly emargi- 

 nato-truncate, the apical angles being very slightly prominent but narrowly 

 rounded ; base transverse and very feebly bisinuate ; disk rather coarsely 

 punctate, the punctures shallow and variolate, liner and sparser toward the 

 middle, very dense laterally. Scutellum moderate, slightly transverse. Elytra 

 subequal in width to the prothorax and about three and oiie-half times as 

 long ; sides nearly straight ; apex rather abruptly rounded ; humeri acutely 

 rectangular and very slightly prominent ; disk with eight discal costae which 

 are abruptly elevated but very fine, the crest of each lying between two series 

 of excessively minute punctures ; intervals very feebly concave, each with a 

 single series of fine, feeble, not very closely-set punctures. Abdomen finely, 

 sparsely punctate, the punctures larger laterally. Length 5.0-6.0 mm.
