tylus. Eyes dark brown ; ocelli vermilion, in rear of eyes, nearer 

 median line. First segment of antennae stout, extending about 

 three-fourths of the distance between the eye and anterior margin 

 of head ; second segment a little more than three times as long as 

 first ; third segment two-thirds as long as second ; fourth segment 

 a trifle longer than third ; fifth segment of about the same length 

 as fourth. Rostrum very stout, reaching to hind coxa? ; first seg- 

 ment wide and thick ; second segment one-third longer than first, 

 enlarging at its junction with third segment, which is of about the 

 same length as first; fourth segment a little shorter than third, 

 terminating in a blunt brown point. Prouotum and scutellum of 

 same color as head. Sides of prouotum sinuate, with fine gran- 

 ular teeth anteriorly ; humeral angles produced into stout acute 

 spines. The callous spots on the anterior part of prouotum bear 

 one or more small green markings ; in some specimens there are 

 small spots of this color at the anterior angles of the pronotum 

 and at the inner ends of the callous spots. Scutellum sinuate 

 behind its middle, reaching slightly upon the membrane. Corium 

 of same color as scutellum ; membrane bronze brown, extending 

 beyond tip of abdomen. Connexivum orange, marked with black 

 at the incisures. Under-surface pale yellow, dotted more or less 

 with red. Legs of same color as under-surface, darkening slightly 

 in some specimens towards the tarsi. Ventral spine very stout,

Podisus bractealus, as described by Fitch, differs from 

 cynicus only in certain small green markings on the prono- 

 tum, scutellum and wing-covers. In our collection there is 

 a series of thirty-seven specimens which shows nearly all the 

 variations between the two species as described. Being 

 unable to distinguish between the species, I tried to obtain 

 specimens of bracteatus from several sources, but was unable 

 to do so. In this difficulty I wrote to Professor Uhler, and 

 found that he also was not familiar with this species. Since 

 that time he has very kindly gone to the trouble to examine 

 the specimen of bracteatus in the Fitch collection at the Na- 

 tional Museum, and has decided that it is but a variety of 

 Say's cynicus. Glover in 1876 expressed the opinion that 

 bracteatus was but a variety of cynicus (Manuscript Notes
