Hub. Nicaragua, Managua (A. Solari). 



This species comes very near such species as D. zunilensis 

 and D. picipes from Guatemala, but appears to differs from them, 

 by the fact that the sexes are more alike than in either, the 

 thorax of the male not being so much enlarged in front, also 

 by the front femora in the male sex being apparently not 

 roughened. The head and thorax are very smooth and shining 

 in both sexes, only the most minute and obsolete punctuation 

 being visible; in the male the thorax is not quite twice as 

 long as wide, it is scarcely enlarged at all in front, the sides 

 are nearly parallel, faintly sinuate, a little wider in the middle, 

 the base is as wide as the front, but more depressed than in 

 its near allies, a few larger punctures, and a small plicate fossa 

 are to be observed along the basal transverse impression. 



The elytra are smoother, and the punctures less confused than 

 in D. picipes. The underside is very glabrous, rufo-piceous with 

 the legs usually darker, except at their bases. 



A very important distinction , exists in the structure of the 

 seventh joint of the antennae which in D. picipes is obconic, 

 angular at its inner apical edge , and so forming the commen- 

 cement of a club, while here it is scarcely widened, so that the 

 four last stand out as an independent club. 



A very large series of examples were obtained by Mr. A. Solari 

 varying a good deal in size but otherwise remarkably uniform.

The species of the genus Crotehia inhabit Central and South 

 America, and are readily recognised by their fusiform shape, 

 coarsely grained eyes, and three jointed club. Mr. Fowler de-
