So well known by figures iu all the popular works ou Entomology 

 that further descriptions of color are useless. The larva is also well 

 known, and is one of the " stinging" caterpillars, the hairs or spines 

 being sufficiently poisonous to cause intense pain and considerable 

 swelling if rudely placed on tender portions of the skin. The venation 

 of primaries is as described. The secondaries have veins 2, 3, and 4 

 from the median vein, at about equal distances. A straight veinlet 

 closes the cell, and 5 and 6 are from the same point at the upper angle. 

 V. 7 is from the outer third of the subcostal. The genitalia are some- 

 what peculiar. The supra-aual plate is broad at base and suddenly 

 narrows, ending in a sort of broad-pointed, spatulate tip. Beneath this 

 is another corneous appendage, which is furcate but does not appear to 

 be part of the plate. The figures will explain the appearance, and 

 reference is made thereto to show the form of side piece as well. The 

 variety does not differ in any respect from the tj'pe form except in the 

 reddish suffusion. This does not seem to be a local characteristic, but 

 I have received type and variety together and have taken the 3 of 

 one and the 9 of the other in copulation.

This species is unknown to me and is not in any collection I have 

 ever seen. I doubt its being an American species, but rather thitik it 

 comes over the border occasionally from Mexico. I reproduce the de 

 scription of Grote & Robinson, but somewhat condensed. 



Head and i)alpi rich dark brown ; antennae testaceous, a little slen- 

 derer than in allied species. Thoracic region above, dark brown; later- 

 ally at insertion of jn^imaries are short whitish scales forming a spread- 

 ing tuft. Abdomen above, bright ochreous brown, beneath thorax and 

 legs rich brown, a little paler than upper side. Primaries, apices acute, 

 but not produced. Basal third with rough or woolly dark brown scales, 

 outwardly defined by a darker shade. These dark brown, rough squamse 

 extend along the costal region to the apex and intrude obliquely down- 

 wardly, twice over the middle of the wing; firstly, obliquely and 

 broadly from the costa over the discal cross vein to the first m. uerA^ule ; 

 this band is thrice regularly scalloped outwardly between the nervules, 

 and includes a white discal dot on the cross vein situate just below the 

 inception of the disco-cellular nervule; secondly, more narrowlj*^ and 

 nearer the apices, the scales forming an even band extending down- 

 ward to first median nervule at a point where the usual transverse line
