46 NEW GENERA AND SPECIES OF BRACONIDAE. 



small and collar-like, mesonotum bulged and decidedly trilobed, 

 the parapsidal grooves being deep and wide; pleurae well 

 developed. Scutellum broad and angulated posteriorly, the 

 shield rather narrow; in front and next the anterior margin 

 are two large shallow smooth foveae separated by a carina. 

 Postscutellum also rather well developed, the metanotum 

 rounded, with a median carina anteriorly and two lateral 

 carinae posteriorly, connected by several irregular transverse 

 ridges. Abdomen long and slender, longer than head and 

 thorax together, subsessile, depressed to the penultimate seg- 

 ment, 1st segment 3 to 4 times longer than its greatest width, 

 2nd a little shorter, 3rd, 4th, 5th and 6th quadrate, the last 

 segment compressed, the very large sternites forming with the 

 inflexed tergites a tig. — 8-shaped genital opening. Ovipositor 

 short and stout, the valves flat. Median carina extends to 

 apex of 4th segment. All the tergites longitudinally striate 

 and umbilicately punctate except last two, which are punctate. 

 Wings hyaline, stigma and veins ochraceous. stigma lanceolate, 

 5 times as long as wide, radius emerging at second-fifth from 

 base, 1st abscissa about one-half second, 3rd nearly reaching 

 tip of wing, 1st cubital and 1st discoidal separate, 2nd cubital 

 parallel-sided, twice as long as high, 1st discoidal short pedi- 

 cillate, recurrent nervure enters 1st cubital cell, transverse 

 median postfurcal, submedian cell longer than median.

In the $ the head and abdomen are darker, the antennae 

 49-segmented. 3rd and 4th segments of the maxillary palpus 

 abnormally swollen and flat, the 5th segment small and top- 

 shaped, lying on the upper face of the 4th segment before the 

 apex, 6th joint long and slender with subdivisions. The ab- 

 domen has 8 visible segments, 1st and 2nd subequal and about 

 twice their width, 3 to 7 quadrate, 8 very short. Penis pro- 

 truding slightly. 



Hemigyroneuron dubiosus, n. sp. 



8 7.5 mms. long. Ochraceous, the head black, the ab- 

 domen outwardly from anterior margin of 2nd segment black 

 or blackish, a suffusion of ochraceous on 2nd segment. An- 

 tennae black beyond 2nd segment. Hind tibiae and femora 

 infuscated. Head transverse, eyes large, extending from the 

 vertex almost to the base of the mandibles. Ocelli very large, 

 the lateral members elliptical; arranged in an equilateral 

 triangle, the lateral members removed from each other about 3 

 times the distance from the border of the eye or from the 

 emargination of the occiput; in front of ocelli the head is 

 deeply impressed, the antennae at the front set into rimmed 

 sockets. Antennae 64-jointed, long and slender, as long as 

 the body. Face and cheeks rather narrow; all transversely 

 rugose, a slight carina on upper part of face, the eyes emar-
