New Hampshire. Four specimens in the National Museum. 



Chastophleps, gen. nov. 



Front of female at vertex slightly wider than, in the male as wide as, either 

 eye, frontal bristles descending about to tip of second antennal joint, two pairs of 

 orbital bristles in both sexes ; face strongly receding, sides bare, each about one, 

 tenth as wide as the median depression, the latter with a low carina in the middle- 

 ridges strongly diverging, their lower ends widely separated, vibrissa strong, inserted 

 near the oral margin, ridges bristly on slightly over their lower half, cheeks less than 

 one-fifth as broad as the eye-height. Eyes bare. Antennoe about as long as the 

 face, the third joint over four times as long as the second; arista pubescent, thick- 

 ened to the middle, the penultimate joint scarcely longer than broad. Proboscis be- 

 yond the basal articulation shorter than height of head, palpi clavate, well developed. 

 Abdomen elongate oval, its four segments in the female sub-equal in length, in the 

 male with a fifth segment half as long as the fourth, macrochretje of second and 

 third segments discal and marginal in the female, only marginal in the male. First 

 vein bristly at least on its apical half, the third bearing a few bristles at its base, the 

 others bare ; apical cell open or short petiolate, terminating near the wing-tip ; hind 

 crossvein nearly perpendicular, about midway between the small crossvein and the 

 bend, the latter arcuate. Hind tibia; not ciliate. Type:

 bristles descending about to middle of second antennal joint, two pairs of orbital 

 bristles in the female, face perpendicular, lower part of head nearly as long as at the 

 base of antennse ; sides of face bare, each about one-ninth as wide as the median 

 depression ; vibrissac inserted near the oral margin, ridges bristly on the lower fourth,
