A NEW AEGIALE (MEGATHYMUS). 



BY DR. HENRY SKINNER, PHILADELPHIA, PENNA. 



Aegiale Streckeri, n. sp., $. — Expands from 23^ inches to 3 inches. 

 Upper side. — Superiors rich brown, but not as bright, nor has the 

 brown as much red in it, as in yuccce. There are three sub-apical costal 

 white spots ; a lemon-yellow spot at end of cell ; there is a row of five 

 yellow spots running across the wing, parallel with the exterior margin ; 

 the upper two are small and square in shape ; the lower three are small 

 and triangular, and there is one in each of the three median interspaces. 

 The inferiors have a yellow marginal border about yi inch in width, the 

 wing being otherwise immaculate, and is clothed with long, silky brown 

 hair. Utider side. — Superiors have the spots repeated. Inferiors are 

 gray, with a varying number of small white spots — one specimen having 

 two and the other five. The female is larger and has the same number 

 of spots as the male ; the three sub-apical spots are white and the 

 remainder yellow ; in the female the five spots on the wing are in two 

 series, the two upper being nearer the exterior margin, and the three 

 lower are nearer the base ; in other words, they do not form a continuous 

 line as in the male. This species has been confounded, in collections, 

 with cofaqui, Strecker, which was described from a female. The male of 

 cofaqui is marked practically like the female, but the male has the long 

 hair on the inferiors as in the new species. This long hair is also con- 

 spicuous in Sireckeri at the base of the superiors below. This fine species 

 is described from two males in iny own collection ; one is from Texas 

 and the other probably from Arizona (the exact locality not being known 

 in either case), and a pair in the collection of Dr. Herman Strecker, of 

 Reading, Pa.; one of these is from Texas^ and was collected by the late 

 Jacob Boll, and the other from the San Juan reconnaissance, made under 

 the charge of Lieut. Ruffner, in Colorado, in 1877. Of the four described 

 species, Nemnoegeni is very different from the other three \ yucac. may be 

 known by the peculiar white spot on the anterior margin of the second- 

 aries below. The spots on the superiors above in Streckeri are small, and 

 all practically of one size, and form a straight row, while in cofaqui the 

 spots are very large, being a quarter of an inch in length ; the secondaries 

 above are also spotted in this species. Streckeri differs in colour very 

 much from the other species, not being nearly so red.
