Unrecognized Species. 

 D. punctatorugosa Blanch., loc. cit., 171; Burm. Handb., iv, 2, p. 263. 

 D. frondicola Blanch, (not Say.), loc. cit. This species has been re- 

 garded as a variety of excavata and perhaps correctly so. 



EXPLANATION OF PLATE. 



The figures in all cases show the form of the clypeal margin and 

 the tarsal claws. The former have been drawn with the aid of the 

 camera lucida to virtually the same scale, and therefore nearly repre- 

 sent the relative size of the head in the different species. This is not 

 true of the claws. 



No references to the plate have been made in the body of the paper, 

 but as the names of the species are arranged alphabetically in the 

 following description, it is easy to ascertain at once whether any given 

 species is represented. 

 D. abnormis. — Clypeus as in 44; claw 47. 

 D. acerba. — Clypeus as in 32; claw 34. 



D. csnea. — Clypeus not very different from 3; claw nearly as in 35. 

 D. ambigua. — Clypeus 35, the median sinuation sometimes more and 

 sometimes less marked than in the figure; claw 34.
