AMERICAN LEPIDOPTERA. 217 



A\TAPLAGA Grote. 



Can. Ent. 9, 71. 



Form slender ; eyes naked ; head scarcely retracted ; clypeus bulging, 

 with a cup like depression, having a tubercle at lower margin ; tongue 

 moderate or weak ; thorax small, convex, with vestituiv consisting of 

 flattened hair; abdomen slender, elongate; legs moderate; tibiae not 

 spinose, anterior with a single claw at tip ; primaries large, with acute, 

 produced apices and roundedly oblique outer margin. 



So far as I can make out this "genus agrees with Pippona in the want 

 of the accessory cell of primaries, but of this I am not at all certain, 

 having no specimens to destroy ; the form of primaries and general ap- 

 pearance indicates a close relationship between the two, but the formation 

 of the clypeus and of the anterior tibia very readily separates them. 



Primaries white at basal third, olive brown beyond, interrupted by an oblique 

 sub-marginal white line dimidiala. 



Primaries white, with two transverse black lines and a series of black spots, form- 

 ing an interrupted sub-marginal line sexseriata. 



A. dimidiata, Grt.Can. Ent. 9, 71 (PI. VIII, fig. 6). 



1 his species is readily recognized by simple markings, well shown in 

 the figure. '1 he base is white and satiny, a dark olive brown shade from 

 the middle to margin, interrupted by an oblique white fascia from tip to 

 the hinder margin near the angle. Secondaries uniform pale smoky 

 brown. Expands \\ inches, 3D millini. 



Habitat. — Colorado. 



A. sexseriata, Grt. Papilio I., 176 (Grotelta), PI. VIII, fig. 7. 



Readily separable from the foregoing by the entirely white primaries, 

 crossed by two deep black lines and a row of black spots near the outer 

 margin. I have the type from Mr. Neumoegen's collection, and it dif- 

 fers from Grote (/a, in which genus it was placed by Mr. Grote, by hav- 

 ing only a single claw terminating the anterior tibia, by the lack of spines 

 on the median pair, and by the more elongate wings. 



The genus is very closely allied to Grote/ta however, the clypeal 

 structure being precisely identical, and the spinose tibiae of Grotella are 

 really all that separate it from Antaplaga. Lack of sufficient material 

 has made it impossible for me to study the neuration. The species seems 

 to lack the accessory cell, but of that I am not at all certain. Expands 

 1 inch, 26 millim. 



Habitat. — Arizona ( Prescott).
