Mr. Kirby having but one specimen of the male, the legs of 

 which I could not clearly see, and having kindly given me 

 females which I could relax, I have drawn the latter sex of 

 this pretty and rare insect, which perfectly agrees with the 

 former excepting the simple antennae, the spot on the posterior 

 thighs, and a slight cloud upon the wings. I could not (from 

 the same cause) satisfy myself perfectly of the club of the an- 

 tennae being composed of 3 joints in the male as I did in the 

 female, neither do I feel positive that the branches are not 

 articulated. The extreme minuteness of the mouth prevented 

 me from obtaining the labrum and mandibles, which I was 

 very anxious to accomplish as the Cynipsidce are less com- 

 plete in their organization than most of the Hymenoptera ; 

 their wings are nerveless, and their palpi and tarsi composed 

 of fewer joints than usual. 



Mr. Westwood having discovered a new species, the de- 

 scription of which he has obligingly communicated as well as 

 some useful remarks, and having another nondescript in my 

 own cabinet, I shall give a short account of all the species.
