thorax with the anterior margin (except along the median third) 

 and an angular patch on each side at the base (these markings con- 

 nected laterally, leaving a large black cruciform patch), and the 

 anterior femora (except along their upper edge), coxae, and tro- 

 chanters, testaceous, the elytra nigro-caeruleous ; finely pubescent 

 and also set with intermixed longer, semi-erect hairs. Head short, 

 broad, minutely punctulate, bi-impressed in front; antennae 

 moderately long, feebly serrate, joints 3-11 much longer than broad. 

 Prothorax convex, small, broader than long, polished, minutely 

 ptmctulate. Elytra moderately long, much broader than the pro- 

 thorax, widened posteriorly; rugulose and densely punctate. 

 Legs slender; posterior tibiae curved. 



Var.(l) The black markings on the prothorax reduced to a 

 median vitta. $. 



Length 2 J mm. 



Hab. Mexico, Jalapa. 



Gorham treated this insect as a variety of his ^4. discima- 

 cula (a species here transferred to the genus Micromimetes), 

 from the female of which (a broken specimen from Guana- 

 juato) it may be identified by its larger size, the much 

 longer, simple antennae, the sharply-defined cruciform 

 black patch on the prothorax, and the broader and more 

 distinctly punctate elytra. A. crux-nigra comes near A. 

 hepburnius, differing from that species in its smaller and 

 more pohshed prothorax, flattened epistoma, etc. The 

 broader head, the more transverse prothorax, the duller, 

 less metalhc elytra, etc., separate A. crux-nigra from A. 

 coelestinus. The description of the present species is 

 taken from a female from Jalapa, and there is another 

 example of the same sex from Cordova (now without a 

 head), also sent by Hoge, which probably belongs to A. 

 crux-tiigra, differing from the other in having the black 

 patch on the prothorax less extended in the middle pos- 

 teriorly. The var. ?, from the Sommer collection, in the 

 Oxford Museum, from " Mexico," may also belong to 

 the same species.
