52 AMERICAN HYMENOPTERA. 



Judging from Cameron's plate the nervulus is interstitial 

 and the nervellus broken at the middle, the discocubital vein 

 arcuate, not appendiculate. I am not sure of the validity of 

 this genus, for the short stout abdomen of the male — the 

 sex of the single specimen known — indicates that the female 

 when discovered may have a long ovipositor or other char- 

 acters which might place it in some other genus. As I have 

 not seen a specimen, however, I have preserved the genus, 

 but further investigation is necessary.

Length 15 mm. (about). 



Head strongly punctured ; a triangular projection below the antennae, 

 its centre almost carinated, the face transversely striated on either 

 side of it; below the antennae, the orbits broadly behind, the palpi, 

 ciypeus (except at the extreme apex), and the labrum yellow. Thorax 

 strongly punctured, shining, the scutellum scarcely so strongly punc- 

 tured as the mesonotum ; metanotum with seven areae ; the sides more 

 or less reticulated. Abdomen shining, impunctate, the ventral surface 

 in the middle obscure yellow. The anterior legs in front and the tarsi 

 are entirely yellow ; the middle pair have the coxae, the greater part 

 of the trochanters, the femora — except the base— and the apices of the 

 tarsi, yellow ; the four apical joints of the hind tarsi are also yellow.
