species of Tenthredinidce and Cynipidcg. 483 



past the 2ncl transverse cubital ; the 2ncl cubital cellule has a 

 horny point ; 3rd cubital cellule longer than broad, of nearly equal 

 breadth throughout ; 2nd recurrent nervure almost interstitial. 

 Abdomen stout, broad at apex, not very much longer than the head 

 and thorax together ; its apex above is dull white ; cerci short, 

 thick, fuscous. Long. 6*5 mm. 



Hab. Mexico, Northern Sonora (Morrison). 



Blennocampa hicolorata, n. s. 

 Black ; pronotum, mesonotum (except scutellum), and tegulae, 

 blood-red; clypeus and labrum dull white. Mandibles piceous. 

 Antennae about as long as the abdomen, thickish, covered with a 

 dense stiff pubescence ; 3rd jomt nearly one-half longer than 4th ; 

 lateral sutures on vertex deep and broad behind, shallow in fi'ont 

 of ocelli ; frontal area not defined, but there is a shallow fovea down 

 from the front ocellus. Clypeus transverse ; first radial cellule the 

 longest ; transverse radial nervure straight and received in the 

 apical third of the 3rd cubital cellule, which is long, and receives 

 the recurrent nervure not far from its base ; the transverse median 

 nervure is received before the middle of the cellule. The wings 

 are dark fuscous. Claws apparently simple. Length, nearly 

 5 mm. 



This species is most nearly related to B. inliahilis, 

 Harris sec. Norton, but that has the antennae shorter ; 

 the abdomen is also shorter, it being " short, nearly as 

 wide as long " ; while in B. hicolorata it is distinctly 

 longer than wide. The mesopleiira is red in front, and 

 the transverse radial nervure is bent and received near 

 the 3rd transverse cubital. 



Hab. Chapulte and Orizaba, Mexico {Bilimik) ; Mus.

Strongylogaster Rogenhoferi, n. s. 

 Abdomen and legs rufo-testaceous. Head black clypeus, 

 labrum, mandibles, and palpi white. Antennae black ; the basal 

 joint and the apex of 4tli to the 7th white. Thorax black ; the 

 edges of the middle lobe of mesonotum, scutellum, tegulae, pro- 

 notum, and the plem-ae, except a small black mark below the 

 tegulse, an oblique one on the mesopleura, and a mark over the 

 middle coxae, white. The antennae are nearly as long as the 

 thorax and abdomen together, but shghtiy thickened beyond the 

 middle; the 3rd joint a little longer than 4th. Sutures on vertex 

 flat and shallow; frontal area not defined; the front ocellus is
