an essential character, viz. the produced and acute gense. But the character is not 

 always strongly pronounced, and is very slight, for instance, in A. villosipes.

 Hal. North America, Florida, Louisiana \ — Mexico, Teapa in Tabasco (H. II. Smith). 



I refer the single example from Teapa to E. castanea with some reserve, Serville's 

 species being known to me only by description. Our insect agrees, however, in form, 

 punctuation, and colour with the careful description of Dr. Horn above cited. In the 

 Southern States, according to Dr. Horn, IE. castanea is found in the nests of a small ant.

Four examples agreeing well with the detailed description above cited, excepting 

 that I am unable to detect the " spinula accessoria " near the apical spurs of the hind 

 tibiae, which is probably a variable character and perceptible only in well-preserved 

 individuals. The outer apical angles of the same tibiae are prolonged and acute. The 

 sculpture of the elytra is similar to that of A. complicatus, from which the present 

 species is readily distinguished by its smaller size (1 millim.) and by the short but sharp 

 tooth on each side of the emargination of the clypeus. The carina? of the elytra, eight 

 in number on each side, are narrow from the base to the apex, each being accompanied 

 by a less elevated and more or less crenulated line on each side, and the punctures of 

 the broad striae are large and strung closely together.
