lus, slightly testaceous; pedicel conical, much narrower and less than 

 half as long as the following joint, dark brown; flagellum about twice 

 as long as the scape, blackish; the first joint not wider at base than 

 the pedicel but much wider at its apex, second joint distinctly shorter 

 than the first, one and a half times as long as thick, third and fourth 

 joints subequal, transverse, about twice as wide as long; club joints 

 transverse, but distinctly longer than joints three and four of the 

 funicle, the two apical sutures slightly oblique, the apical joint round- 

 ed at its apex. Head black, strongly transverse; mandibles deeply 

 toothed and brownish; clypeus strongly transversely striate; lower 

 part of face, eye margins above, the temples, cheeks, and vertex also 

 deeply striate; remainder of the face smooth and shining but with 

 many deep punctures arranged in irregular rows on the upper half. 

 Thorax black; mesothorax and scutellum coarsely punctate, meso- 

 pleura? rugoso-striate; metathorax more or less rugoso-striate with 

 three long pointed projections, one on the median line reaching to the 

 middle of the first abdominal segment, and one at each posterior lateral 

 angle considerably shorter. Wings slightly smoky, with a row of 

 stiff black bristles along the subcostal and marginal veins. Legs in- 

 cluding all coxae brownish testaceous. Abdomen shining black, longer 

 than the head and thorax, spatulate, the first segment wider at 

 apex than long, its base narrow; second segment also much wider at 

 apex than at base and about half as long as wide; third segment as 

 long as two and three together, the following segments very short; 

 segments one, two, and three are strongly longitudinally striate, the 

 striations gradually fading out and disappearing before the apex and 

 at the sides of the third. 



Habitat: Manhattan, Kansas. 



Type: No. 14354, U. S. National Museum. 



One specimen was received from T. J. Headlee which had 

 been secured from a cage in which experiments with the Hes- 

 sian fly were being carried on and it is possibly, though not 

 likely, a parasite of the fly. 



The species is closest to H. bethunei Sanders, recently de- 

 scribed, but differs as follows: The thorax is densely punc- 

 tate instead of rugose, the metathoracic teeth are much longer, 

 and the flagellum is more strongly dilated. 



Mr. Busck gave a very interesting account of the rearing 

 of the man-infesting bot of tropical America.
