The liead is small, not more than one-third the width of thorax. Eyes very large. 

 Palpi barely exceeding the head, wi.h long hairs at their base, the terminal article 

 small, and sharply pointed. Antenni^ closely and dee|)ly pectinated. Thorax densely 

 tufied with short scale-like hairs. Abdomen cylindrical, dotted with fhort hairs. 

 Feet and legs are covered with hair to the base of the tarsi, whijh are also sparsely 

 clothed with hairs. Wings much narro\\er than usual in the genus Cossiis, the 

 >econdaries being a little more than half the length of primaries. Th; median cell f f 

 both wings is divided, and there is an accessory cell on the primaries only. The in- 

 ternal vein of primaries is reduced to a mere fold, and there is a connecting,' vein 

 between the coital and sHhcostal of secondaries. f)thjr\v!s^', the naua'ion resemliKs 

 that of Cossiis. 



Inguromorpha Slossoni, n. sp. 



Pcde gray. At liase of primaries i.-. a d^ep hia.k transvers.' hand, extending 

 quite across the \\ing. At internal angle and apex are distinct black lines forming 

 circles, the enclosed spaces being dotted with brownish black scales, and there are 

 also several irregular black (kishes on the rest of the wing. The secondaries are pale 

 gray, with faint black reticulations. The under side has the markings repeated, but 

 a little more taiiitly. Thorax, and abdomen gray, widi hiacki.-h mottling. 



Exo. wings, 32 mm. Length of body. 15 mm. 



From I ^, taken at Jacksonville, Florida, at electric light, by j\Irs. 

 A. Trumbull Slosson, to whcmi I re.spectfully dedicate it. I have taken 

 considerable pains to compare this singular species with the descriptions 

 of those in our lists which are unknown to the general entomologist, and 

 cannot make it to be anything but a new species. It is certainly not C. 

 nanus of Strecker, as that is said to resemble C. ligniperda. It is not at 

 all like the descriptions of Walker's C. plagiahis or C. populi, and differs 

 also greatly in size, these two being each said to be 18 lines, or 2^ inches 

 in expanse, while the present species is only r^ inches. Lintner's C. 

 undosus would appear, if perfect, to be of the satne size as Walker's spe- 

 cies. The markings too, are very difl'eient (rom either of them, the strange 

 circular apical blotch, and the distinct biack basal transverse line being 

 strong characters. I shall endeavour at an early day to give a figure of 

 this very interesting species. 



Arctia Brucei, n. sp. 



J . Ground color of primaries brownish black. At the base is a rosy red patch, 

 enclosing 3 black dashes. Costa for its entire length, a large triangular patch in the 

 middle, an almost straight line from costa to internal margin, fringe and inteinal 

 margin all rosy red. The line across the wing is slightly bent about its middle, and 

 from it are two slight dashes, indicating the W mark common to the genus, but in 

 this sex there is no trace of the mark beyond these faint lines. Secondaries wholly 

 rosy red, with broken maculate marginal band. Head chestnut brown. Shaft of 

 antennte fawn color. Disc of thorax, upper side of abdomen, pectus, base of femora, 

 and pectinations of antennae brown. Collar, tibia;, and abdomen beneath and at the 

 sides, rosy red. Underside of wings marked as above, Init more fiintly. 

 * O. Similar to the q", but the red is brighter and the mark on the oiitir thiid 

 »if the wing more distinct. It is however, moi-e like the letter X than W, aid ili.-
