Genus HIMANTOPYGA Frey 



The above jreniis was compared Avith Sapromj/za Fallen by Doctor 

 Frey, "nvIio distinguished it essentially by its more slender form, its 

 much developed male hypopygium, and the projecting labrum. The 

 prescutellar acrostichals are absent and all the tibiae have a long 

 preapical dorsal bristle.

 spot black, with gray dust; orbitals both strong, the anterior pair 

 not much shorter than the posterior pair; antennae black, third seg-

 bare; palpi yellow to brownish. Thorax and scutellum shining black, 

 with slight gray dust, the humeri and sutures yellowish ; three dorso- 

 centrals, acrotichals in six series, two sernopleurals present; scutellum

Genus POICHILUS Frey 



This genus also is unknown to me. I append some notes taken 

 from Doctor Frey's published description. 



Said to have much in common with the genus Mycterella Kertesz. 

 The arista is long haired and the eyes have a different form. Also 

 near Rhayadolyra Hendel. 



Ocellars very short and fine, two verticals and two orbitals, all 

 strong and equal; face convex; basal antennal segment shorter than 

 second, third slender, about five times as long as wide ; arista dorsal, 

 basal, twice as long as third antennal segment, and with long dense 

 hairs on each side; prelabrum hardly projecting; palpi normal. 

 Thorax with three pairs of postsutural dorsocentrals, one pair of 

 jorescutellar acrostichals, two sternopleurals, the scutellum large, flat- 

 tened, rounded in outline, with four bristles. All tibiae with preapical 

 dorsal bristle. Second and third wing veins slightly undulated.
