bristles in five pairs, one decussate apical, three lateral, of which

 discal pair. 



Abdomen above of four visible segments, macrochaetae only mar- 

 ginal. 



Wings reaching well beyond end of abdomen, apical cell narrowly 

 open just before and almost in wing-tip, ultimate section of fourth 

 vein bowed in about the middle so as to attenuate the terminal por- 

 tion of apical cell. Hind crossvein slightly curved, not quite in 

 middle between small crossvein and bend of fourth vein, distinctly 

 nearer latter. None of the veins spined, the small crossvein slightly 

 or distinctly before middle of discal cell. 



Legs normal, hind tibiae weakly ciliate, with a bristle or two 

 among the cilia, claws and pulvilli very short. Type, T. cinerea,

Comes near Pseudochccta Coquillett. with which it agrees in the

 from which it differs as follows : 



Pseudochccta Trepophrys 



Antennae inserted distinctly above Antennae inserted practically on eye 



eye middle in both sexes, but es- middle in both sexes, 



pecially so in the male. Three sternopleural bristles. 



Two sternopleural bristles. Three postsutural bristles. 



Four postsutural bristles. Apical cell ending slightly before, 



Apical cell ending not far but very almost in, wing-tip.

male; nearer bend of fourth vein, middle, female, 



female. ' Small crossvein well before middle 



'Small crossvein nearly in middle of of discal cell, male; nearly in mid- 



discal cell, male; before middle, die, female. 



female. Wings elongated beyond end of ab- 



Wings very short and broad, hardly domen. at least two and one-half 



more than twice as long as wide. times as long as broad. 



Head distinctly widened. Head hardly wider than thorax. 



Trepophrys cinerea, sp. nov. 



Three specimens bred from masses of pupae of a tortricid, Amy- 

 dria sp., sent by Prof. A. L. Herrera, from Cuernavaca, Mexico. 



Length, 4.5 to nearly 6 mm. Blackish, parafrontals and para- 

 facials golden, extending on occipital orbits ; frontalia, antennae, and
