and Central American Malachiidae and Melyridae. 85 



of the hind tibiae of the female, except under A. calcaratus. 

 The four specimens before me from Taboga include a pair 

 remounted by him on the same piece of card, and labelled 

 "A. fuscescens, type," the others being females. The 

 elytra vary in colour from wholly black to hvid testaceous 

 with the base broadly and indeterminately black. The 

 posterior femora are sometimes infuscate to near the tip. 

 The eyes are large. 



2. Anthocomus viridescens, n. sp. 



Elongate, narrow, shining ; black, the head (except at the antennal 

 insertion) and prothorax aeneous, the latter with the margins and 

 base testaceous, the elytra greenish, the basal joints of the antennae 

 and the tarsal joints 1-4 testaceous or obscure testaceous, the femora 

 and tibiae piceous; sparsely pubescent and also set with semierect 

 bristly hairs. Head transverse, polished, with excessively minute 

 scattered punctures ; eyes moderately large ; antennae short in both 

 sexes. Prothorax convex, slightly broader than long, sparsely, 

 minutely punctate. Elytra long, slightly widened posteriorly in 

 ^, a little more inflated behind in $, not much broader than the 

 prothorax at the base; rugulose, closely, conspicuously punctate. 

 Legs slender; posterior tibiae moderately curved and simple in 

 both sexes. 



Length 2 mm. ((J$.) 



Hab. Mexico (Truqui, in Mus. Brit.). 



Two specimens, assumed to be sexes of the same species. 

 A. viridescens agrees with A. fuscescens in having simple 

 5- jointed anterior tarsi in the male; but differs from it in 

 the unarmed, feebly curved posterior tibiae of the female, 

 the metalhc coloration, the smaller eyes, the rugulose, 

 conspicuously punctate elytra, etc. The elytra are obliquely 

 compressed at the tip in the male.
