The male of this species has never been described, but 

 to it I refer a single S from San Jose del Cabo, which dif- 

 fers in no ways from the ? , except in its smaller size and 

 in the usual sexual differences. 



9. Bracon foxii sp. n. 



? . — Length 6.5 mm.; ovipositor about twice as long 

 as the abdomen. Reddish-yellow; the stemmaticum, 

 antenna, palpi and legs, except the hind coxse and basal 

 two-thirds of hind femora, black. Wings smoky black, 

 subhyaline at base, the tegulas, stigma and veins black. 



The surface is smooth, highly polished, impunctate; 

 head subquadrate, the face feebly punctate and clothed 

 with glittering white pile ; the under su^f ace of the thorax 

 and the legs are also clothed with pile, but more sparsely 

 so. Abdomen smooth, but the second segment has a tri- 

 angular elevation at the basal middle, with broad depres- 

 sion on each side of it, while the third has two oblique 

 lateral furrows, and is separated from the second by a 

 deep slightly arcuate but smooth furrow. 



Described from one ? specimen from San Jose del Cabo. 

 This lovely species is dedicated to Wm. J. Fox, as a slight 

 appreciation of the many favors he has shown me.
