mid Central American Malachiidae and Melyridae. 67 



The six examples seen of this species are all females. 

 It may be known by its shining head and prothorax, and 

 rather dull, opalescent, obsoletely punctate, purpMsh 

 elytra. The head has at least the anterior half testaceous, 

 the black portion being sometimes reduced to a transverse 

 space on the vertex ; the prothorax is small and transverse, 

 in some specimens almost wholly black, in others red ; the 

 elytra are much widened posteriorly; the pubescence is 

 sparse, and the elytra, as usual, are set with longer, inter- 

 mixed, semierect hairs ; the posterior tibiae (?) are strongly 

 curved, and the posterior femora are infuscate,

9. Moderately elongate, rather narrow, shining, the elytra sub- 

 opaque; testaceous, the prothorax with a broad median vitta 

 (nearly reaching the base), and the under surface in part (that of 

 the prothorax excepted), black; the elytra with the outer limb to 

 beyond the middle, and the apices narrowly, flavo-testaceous, for 

 the rest dark purplish -brown, appearing opalescent or glaucous in 

 certain lights; the middle and hind tarsi and the apices of the 

 antennae more or less infuscate ; finely pubescent, with intermixed 

 longer, semierect hairs. Head broad, short, closely, minutely 

 punctulate; antennae short. Prothorax very convex, ample, 

 transverse, closely, minutely punctulate. Elytra moderately long 

 a little widened posteriorly, very little broader than the prothorax 

 at the base, densely, minutely punctulate. Legs long and rather 

 slender.

One female. Near A. opalinus, Gorh., from Chiriqui, 

 differing from that insect in its broader head, more ample, 

 nigro-vittate prothorax, and duller elytra, the apices of 

 which are yellow. The present species is not unhke the 

 European A. amictus, Er.

The type of this species also is a female. It is very like 

 the Mexican A. sapphirinus, but is readily separable by the 

 more elongate elytra ; the sides of the latter, and the base
