282 MEMOIRS ON THE COLEOPTERA 



prothorax scarcely more than two-fifths wider than long, more quad- 

 rate than usual, the sides broadly arcuate, more converging ante- 

 riorly, the basal angles broadly rounded; apex three-fourths as wide 

 as the base, very feebly sinuate, with obtusely rounded angles; 

 transverse impressions barely traceable, the stria fine but rather 

 impressed; punctures of the foveal regions wide-spread, numerous 

 and moderate in size; foveae broadly and extremely feebly impressed, 

 the outer distinctly the smaller and less linear; elytra nearly one- 

 half longer than wide, exactly equal in width to the prothorax, 

 rather rapidly ogival behind, the sides feebly arcuate, the lateral 

 series not interrupted; striae moderately fine, with small but strong, 

 close-set punctures, deeply impressed (cf) or less so (9), the scu- 

 tellar moderate, entire, widely free at tip; intervals strongly convex 

 (cf ) or broadly and moderately (9 ) Length (cf 9 ) 6.2-6.7 mm.; 

 width 2.5-2.8 mm. New York (Long Island), Shoemaker. 



liquida n. sp. 



13 Elytral strise completely devoid of punctures. Elongate, subpar- 

 allel, convex, polished, obscure testaceous, brighter beneath, the 

 legs pale; elytra blackish; head nearly three-fifths as wide as the 

 prothorax, with prominent eyes and deep linear oblique strioles; 

 antennae dark ferruginous, extending far behind the thoracic base; 

 prothorax nearly one-half wider than long, the sides broadly arcu- 

 ate, gradually slightly more converging anteriorly, the basal angles 

 more than right and distinctly rounded; apex fully three-fourths as 

 wide as the base, very feebly sinuate, with broadly blunt angles; 

 impressions obsolete, the stria fine, not impressed; punctures of the 

 foveal regions numerous, very moderate; foveae broadly, moderately 

 impressed, the inner broadly sublinear, the outer more rounded, 

 close to the base; elytra two-fifths longer than wide, barely visibly 

 wider than the prothorax, rapidly ogival in apical third, the sides 

 feebly arcuate; striae moderately fine but sharply groove-like, the 

 scutellar entire and widely free at tip; lateral series narrowly inter- 

 rupted; intervals very feebly convex; abdomen with a small discal 

 impression near the side of each segment. Length (c? 1 ) 6.2 mm.; 

 width 2.4 mm. Mexico (Colonia Garcia, Sierra Madre Mts., Chi- 

 huahua), Townsend *chihuahuae n. sp. 



Elytral striae punctured 14 



14 Striae finely and feebly punctate, the punctures only discoverable 

 by close observation under anteriorly reflected light; Sonoran fauna. 

 Body oblong-suboval, only moderately convex, polished through- 

 out in both sexes and pale testaceous, the elytra very slightly more 

 obscure; head small, with very prominent eyes, half as wide as the 

 prothorax, the strioles feebly impressed and punctiformt antennae 

 moderate though extending behind the thoracic base, very pale fer- 

 ruginous; prothorax one-half to three-fifths wider than long, the 

 sides arcuately converging in anterior, parallel and nearly straight in 

 about posterior, half, the basal angles barely more than right, nar- 

 rowly rounded; apex not three-fourths as wide as the base, just 

 visibly sinuate or subtruncate, with broadly rounded angles; impres- 

 sions obsolete, the stria fine; punctures of the foveal regions very
