Adui.t. 



Specimens of Macrohasis unkol<jr eolh-cted at (Jarde:) City. Kaus., averaged 

 about 13.6 mm. long and 3.4 mm. wide. Blatchley gives the limits of their 

 variation in length as 8 to 15 mm. It is the slen- 

 derest of our species (fig. 9) and the sides are almost 

 parallel ; color ashy gray, sometimes with a yellow- 

 ish cast, but more uniform than in any other species 

 collected at Garden City, except the black ones. 



Egg. 



The eggs were not secured nor were the growing 

 stages of the larva^ identified. 



COARCTATE LaRVA. 



Five specimens vary in length from 10 to 1'2 

 mm., and in width from 4.5 to 5.5 mm. They are 

 rather slendei- and of a yellowish brown color. In 

 other ways they agree with the coarctate larvte of 

 Ma crohasis hn m aeulnta.

Snuiller and more slender than the corresponding stage in .1/. iiiimuvttlata, 

 but otherwise similar thereto.

The only specimen measured was 10 mm. long by 3 mm. wide. Though 

 smaller and more slender it was otherwise similar to the pupa of M. imimH'U-
