Length, 3.35 mm; width, 1.35 mm. 



Type locality. — Real de Arriba, Mexico, D.F. 



7^y;^e.— U.S.N.M. No. 49578. 



Remarks. — Described from a unique male collected at the type 

 locality at an altitude of 6,300 feet, July 16, 1932, by H. E. Hinton. 



This species resembles Callhnicra lucida Waterhouse, but it be- 

 longs to the genus Lius and differs from lucida in having the pro- 

 notum reddish cupreous, uniformly convex, and without lateral car- 

 inae, the head deeply depressed in front, the prosternal process nar- 

 row, with the sides constricted at the middle, and the metasternum 

 very deeply and narrowly emarginate in front. 



CALLIMICRA CYANESCENS, new species 



Female. — Rather narrowly oblong, moderately convex, broadly, 

 equally rounded in front and behind, rather strongly shining; above 

 uniformly dark greenish blue, with a feeble violaceous tinge on the 

 elytra ; beneath piceous, with a vague aeneous reflection in certain 

 lights. 



Head with the front broad, moderately convex, subequal in width 

 at top and bottom, lateral margins parallel, feebly longitudinally 

 depressed behind the epistoma, and with a narrow, longitudinal 

 carina extending from the occiput to a round, deep, median depres- 

 sion on the front; frontal pores very large, situated at the lateral 

 margins and connected internall}^ by a deep, transverse groove, which 

 is interrupted at the middle ; surface glabrous, finely, densely reticu- 

 late, sparsely, coarsely, irregularly punctate; epistoma very narrow 

 between the antennal cavities, strongly elevated, the antennae nearly 

 contiguous. 



Pronotum moderately convex, one and one half times as wide as 

 long, slightly narrower at apex than at base, and widest at basal 

 third ; sides feebly arcuate from base to middle, then strongly, arcu- 

 ately narrowed to the apical angles; posterior angles obtuse; ante- 

 rior margin rather strongly sinuate, with a broadly rounded, obsolete, 

 median lobe; base transversely truncate to middle of each elytron, 

 then turning obliquely backward to the scutellum, in front of which 

 it is broadly subtruncate; surface broadly, deeply, transversely de- 

 pressed along base, narrowly depressed along lateral margins, with 

 obsolete lateral carinae extending from base to middle of pronotum, 

 glabrous, finely, sparsely, irregularly punctate. Scutellum broadly 

 triangular, anterior margin truncate, the surface nearly smooth. 



Elytra moderately convex, about as wide as pronotum at base; 

 humeral angles obtuse ; sides nearly parallel from base to apical third 

 (feebly, arcuately constricted at middle), then arcuately narrowed 

 to the tips, which are separately rather broadly rounded, with the
