mentary, scaled at the base. Fore wings with ten veins 4 

 and 5 coalesce so as to appear as one ; 7 arises from the stem 

 of 8 and 9 ; 10 and 11 coalesce, forming one vein. Hind 

 wings with a distinct pecten of hairs on the basal part of the 

 median vein on the upper side ; seven veins ; 4 and 5 coa- 

 lesce, forming but one vein. 



This genus was established by Rev. Geo. D. Hulst in 

 " Entomologica Americana," Vol. IV., p. 116, 1888. 



UlNTA OREADELLA Hulst. (Plate VI., fig. 14.) 



Expanse of wings, 15 mm. (about three-fifths of an inch). 

 Head and palpi very dark gray ; thorax blackish gray. Fore 

 wings dark fuscous, darker at the base ; basal line wanting ; 

 outer line broad, dark brown ; terminal line also dark brown, 

 and a dark-brown dot occurs near the middle of the wing.

 Hind wings fuscous. 



Only a single example of this species is at present known, 

 and that is in the collection of the Rev. G. D. Hulst, who 

 received it from Colorado, and published the description of 

 it in "Entomologica Americana," Vol. IV., p. 116, 1888. 

 I am under obligations to Mr. Hulst for the loan of this and 

 other insects from which to make the drawings that appear 

 in this work. Nothing is known of the early stages and 

 habits of this rare insect. 



PRIONAPTERYX STEPHENS. 



Head medium, face slightly cone-shaped ; eyes large, nearly 

 hemispherical; ocelli absent; antennae serrate in the male, 

 simple in the female, nearly two-thirds as long as the costa ; 

 labial palpi porrect, about twice as long as the head and 

 coarsely scaled at the end ; maxillary palpi triangular, half as 

 long as the labial palpi , and resting on them ; tongue well devel- 

 oped ; thorax and abdomen smooth. Fore wings with twelve 

 veins, 6 and 7 from one point or stalked, 11 and 12 approach 

 very near or join near the middle of 11, after which they run 

 separately to the costa ; outer margin notched near the end 

 of vein 5. This genus was established by Stephens for a 

 mutilated example of an insect which he described under 

 the name of nebulifera , and of which he says : * * Of this sin-
