Sent in plenty by Herr Hoge from the above Mexican localities. Varies in colour, 
in the intensity of the punctuation of the head, and in the depth and size of the punc- 
tures of the elytral series, also in having the elytral interstices slightly convex in some 
specimens. ‘The head usually has the punctures finer on the anterior part: in the 
specimens from Paso del Norte (A. nitida, Casey) they are denser than in the type of 
A. rufipes, while in some of those from Durango city they are very fine, sparse, and 
uniform. In one male from Durango city the posterior femoral teeth are almost 
obsolete ; the first ventral segment, as noted by Capt. Casey, is tuberculate in the 
middle in this sex. A. ntida was described from a single male example.
