A. tenuis Lee. Proc. Ac. Phil. VII, p. 81. 



Length 1.25 mm. = .50 inch. Hab. Texas and Arizona. 

 In this species, as in the preceding, the palpi are not dilated and 

 are not very unequal; the hind tibiae are however much more distinctly 

 carinaled, the spine of the 3d antennal joint is two-thirds as long as the 

 4 th joint and the spine of the latter is quite small. 



A. volitans Lee. S.M.C. No. 264. 1873, p. 186. 



Length 10 mm. = .40 inch. Hab. Lower Cal. 

 In this species as in prot.nsus the first joint of the antennae is longer 

 and less thickened than in linearis and slightly curved, the outer joints 

 are scarcely carinate, the spine of the 3d joint is two-thirds as long as the 

 4th joint and the spine of tne latter is also long, being fully one third as 

 long as 5th joint. The hind tibiae are only feebly carinate. 



A. prolixus Lee. S.M.C. No. 264, 1873, p. 203. 



Length 25 mm. = 1 inch. Hab. Lower Cal. 



The antenna? are very distinctly carinate, of $ nearly as long as body, 



9 scarcely two-thirds as long. The appearance of a transverse line on 

 the disk of prothorax is the result of the arrangement of the pubescence 

 rather than a positive elevation.

[By the error of the Photo Engraving Co., the plates were made 

 rather smaller than ordered. The actual size of insects iigured is therefore 

 somewhat greater than indicated. Most of the species here figured were 

 described in Bulletin, Vol. VII.]
