NOKTH-AMaRICAN HETP^ROCEEES — STRECKER. 271 



black spots. Upper surface : Primaries; pale yellowish flesh colored, with black 

 spots or marks, to-wit: three basal, the one of which ue;irest the inner margin 

 islougiluclinal. the one nearest the base atcosta also longitudinal, its fellow ex- 

 terior to it oval ; these three basal spots are succeeded by two others, the 

 costal lunate, and the one at interior margm rhombus shaped ; following these 

 is one ver3' large irregular, somewhat triangular shaped mark, extending 

 from costa two-thirds across the wing; opposite to it at inner margin is a very 

 small oblong mark; between these and the outer margin are three triangular 

 spots, that at costa being the largest, the other tvvo, one of which is at inner 

 angle, are nearly of one size; at apex is a lunate spot, at middle of exterior 

 margin a large, triangular spot, and towards inner angle a very small spot. 

 Fringe same color as ground of wing. Secondaries same scarlet as upper side 

 of abdomen; a sub-marginal row of three large black spots, the innermost of 

 which touches the outer margin near the anal angle; the outermost merges into 

 the rather narrow black co^tat border not far from the apex ; apex with a narrow 

 black mark; in the middle of the exterior margin is a small triangular spot; 

 two other spots connect with the costal border; a small round spot at the 

 outer extremity of discal cell, and another half way between it and the 

 abdominal margin. Fringe same pale yellowish as the ground color of prima- 

 ries. Under surf iwe: All wings pale yellowish ; primaries darker along the 

 costa; secondaries tinged with pink tovvards the abdominal mrgin; all the 

 spots of the upper surface exactly repeated, but not as deeply black as above. 



Described from one i, for which I am indebted to the kindness of Mr. 

 G. H. French, of Carbondale, Ills., who stated that he received it from 

 Gilpin County, Colorado, at an elevation of about 8,-500 feet. In general 

 appearance this fine insect reminds one of A. PhqUira, Dru., its nearest 

 ally, but it is larger, and the black marks of primaries are mitch more 

 numerous than in that species. A. Virgo, J^., Intermedia, Stretch, Par- 

 thenice, Kby,' i'ud Acliaia, Grote, are separated from it by having the 

 venation through the black marks of primaries conspicuously designated 

 by being of the same pale color as ground of wing. From A. Behrii, 

 Stretch, it is easilydistinguished by the black thorax of the former. 



Arctia Quadraxotata, N. Sp. 



(Plate IX, fig. 6 2.) 



? expands Ifg inches. Head, antennii?, thorax and legs entirely black; ab- 

 domen above vermillion red, with a dorsal row of large, black, confluent 

 spots; beneath black. Primaries elongate and narrower comparatively than 

 in any other North American species known ; upper surface deep uniform 

 black, with two conspicuous, but not large, yellowi.sh white, egg-shaped spots, 

 with the narrow end directed tovvards the inner margin; the larger of these 

 spots is within the discoidal cell, towards, but not at its outer extremity; the 

 other, which is less than half the size, is half waj' between the last described 

 spot and the exterior margin : fringe black. Secondaries vermillion ; a rather 

 narrow black costal border; a broad black border to exterior margin, which 

 extends inwards in a blunt point at the middle of its inner edge; fri^nge black. 

 Under surface same as above, but less intense in color, and with a third small 

 whitish spot in primaries, situated at the base. 



This species, so totally unlike any previously described, I received 

 from Texas in several examples ; there are also examples in the Museum 

 of Comparative Zoology at Cambridge, likewise from Texas.
