 basai half, a triangle in the base of the 3 ri1 , extending slightly 

 beyond the 2 nd récurrent nervure; and the apical three-fourths of 

 the discoidal cellule between the apex of the l st récurrent and 

 the 2 nd , it being fainter at the apex, and there is a faint cloud in 

 the apex of the fore wings; the stigma and nervures are black, 

 the nervellus in the fore wings post- in the hinder antefurcal; 

 the 2 nd abscissa of the radius twice the length of the l st and 

 about half the length of the 3 nl . the l st récurrent nervure received 

 beyond the middle, the 2 ml near the base of the basai Court h of 

 the cellule. Pygidium white. cf. 



Length 12 mill.

Eyes distinctly converging above ; the hinder ocelli separated 

 from each other by a less distance than tbey are from the eyes.

Sphex (Parasphex) curvilineatus sp. n. — Black, the 

 dilated apical part of the pétiole, the 2 nd abdominal segment except 

 for a large semicircular mark, extending from the apex to shortly 

 behind the middle and laterally to the outer edges, a triangle on 

 the base of the 3 r<1 below, and its ventral side, red; the apices of 

 segments 1-6 with narrow pale ivory yellow Unes, that on the 

 l st distinctly, on the 2 Dd dilated, that on the 2 nd and 3 nl clearly 

 curved ; the hair on head and thorax long, dense and whitish 

 cinereous; wings hyaline, the stigma and nervures black; the 

 3 nl abscissa of radius as long as the l st and fully half the length of 

 the 2 nd ; the l st récurrent nervure is received near the apex of the 

 basai third, further from it than is the 2 nd from the 2 ml transverse 

 cubital. The few tibial and the more numerous tarsal spines are 

 white; the long spur of the hind tibias is for the greater part 

 rufous. Abdominal pétiole long and curved, as long as the hind 

 coxse, trochanters and the basai third of the femora united, and 

 nearly as long as the basai 3 joints of the hind tarsi ; it is slender; 

 the dilated apex forms a broad triangle. çÇ.
