2O2 MEMOIRS ON THE COLEOPTERA 



fifths as wide as the prothorax, the sulci widely diverging poste- 

 riorly, feebly convergent anteriorly; eyes notably large, very prom- 

 inent; antennse as long as the elytra, piceous, the basal joint flavate; 

 prothorax three-fourths wider than long, widest at apical third, the 

 sides there evenly rounded, oblique and straight in somewhat more 

 than basal half, the angles obtuse, reflexed and blunt at apex; sub- 

 basal impression rather deeply impressed, angulate; elytra fully one- 

 half longer than wide, somewhat more than one-half wider than the 

 prothorax and subcircularly rounded in apical third, parallel, with 

 slightly arcuate sides and abruptly rounded humeri; all five striae 

 are distinct to feeble; foveae strong, near two-fifths and five-sixths. 

 Length 2.0 mm.; width 0.8 mm. Texas (El Paso). A single exam- 

 ple taken by the writer spadix n. sp. 



Body oblong-suboval, moderately convex, shining, uniformly castaneous- 

 brown, the head a little darker; under surface dusky testaceous, the 

 legs and epipleura flavate; head well developed, t ( hough scarcely as 

 wide as an elytron, three-fourths as wide as the prothorax, the sulci 

 as in spadix; eyes relatively even larger, very prominent; antennse 

 fuscous, the basal joint flavate, slightly longer than the elytra; pro- 

 thorax shorter and broader, very nearly twice as wide as long, the 

 sides rather widely reflexed, broadly rounded, gradually very mod- 

 erately oblique and straight behind, the reflexed angles very obtuse 

 and blunt, the subbasal impression deep, broadly angulate; elytra 

 shorter, barely wider behind the middle than at base, barely one-half 

 wider than the prothorax and rather less than one-half longer than 

 wide; apex ogivally rounded; sides feebly arcuate, the humeri nar- 

 rowly rounded; first and second striae distinct, the third subobsolete, 

 more evident and widely impressed basally, the others obsolete; an- 

 terior fovea deep, at three-sevenths. Length 1.82 mm.; width 0.8 

 mm. Texas (Houston). A single example taken by the writer. 



laxicollis n. sp. 



Body narrower, still smaller, moderately convex and shining, pale-flavo- 

 testaceous in color throughout, the head piceous-black; legs pale 

 flavate; head relatively still larger, with large and very prominent 

 eyes, fully four-fifths as wide as the prothorax and somewhat wider 

 than an elytron; sulci anterior and moderate, the posteriorly diver- 

 ging part very fine: antennae fuscous, with flavate basal joint, slen- 

 der, as long as the elytra, the second joint even somewhat longer 

 than the first, one-half longer than the third; prothorax a little more 

 than one-half wider than long, the sides subevenly, not strongly 

 rounded anteriorly, feebly oblique and straight posteriorly, the ob- 

 tuse and blunt angles well reflexed, the anterior angles rounded as 

 usual; subbasal impression deep, subarcuate, the surface between 

 it and the basal margin swollen; elytra parallel, with evenly and mod- 

 erately arcuate sides, slightly more than one-half longer than wide 

 and rather less than one-half wider than the prothorax. almost cir- 

 cularly rounded in apical third, the humeri narrowly rounded; 

 striae one to four visible, gradually decreasing in depth; anterior 

 fovea near two-fifths. Length 1.75-1.8 mm.; width 0.65 mm.
