ing tooth. The uncus, viewed laterally, appears stout, with a distinct 

 backwardly-projecting knob at its central portion, and terminates in a 

 stout but acutely-pointed claw which extends cephalo-ventrad. Viewed 

 caudally it is wish-bone shaped, the arms strongly curving and rather 

 well separated apically. The ventral piece has the arms separated by 

 a broadly rounded incision so that they are pressed against the sides 

 of the supra-anal plate. The last ventral segment of the male is about 

 twice as wide as long, the lateral margins slightly sinuate, and the apex 

 nearly truncate. The pygofers of the female have the lateral margins 

 rounding to the acute median tooth. The last ventral segment of the 

 female is a little over twice as wide as long, the angulate emargination 

 of the posterior margin reaching about one-fourth of the distance to the 

 base. The lateral pieces of the ovipositor each bear about nine rounded 

 and quite distinct teeth cephalad of which there is an indistinct ridge. 



Distribution: While there are a goodly number of specimens 

 of this species in the Snow collection, an examination reveals 

 that all our Kansas specimens were taken in Barber county. 

 And this seems to be the only record for Kansas. Davis re- 

 ports this species from Texas, Arizona and New Mexico. Thus 

 it seems to be a distinctively southern form, and possibly 

 reaches its northern limits in Kansas. 



Remarks: Two of the specimens at hand are paratypes.

A rather small, usually greenish and black species which, however, 

 varies to reddish-brown and black. Specimens at hand measure from 

 21 to 23 mm. 



Color: Head black, with a broad, green band extending from the 

 front along each side, along the antennal ledges to the eyes, and with 

 large, green spots laterad of the lateral ocelli and extending along the 

 posterior margin to the eyes. This leaves the black portion of the head 

 in the form of a cross vdth a short and broad standard extending from 

 the front to the posterior margin, and long and slender arms reaching t'j 

 the eyes. Pronotum mostly green, with two black triangular spots on 

 anterior portion which taper posteriorly and then widen just cephalad 

 of the collar into triangular spots, the four enclosing an elongate median
