inward, taperiiis very slowly to a line point, anteriorly very minutely spicu- 

 liferous, the other posterior and a little outside the former, not very long, nearly 

 straight but turned backward, tapering, slender, finely pointed, apparently smooth ; 

 second, a ventrostigmatal row of hairs seated upon rather high papillae, three on a 

 segment, long and slender, quite straight, turned a little backward, very minutely 

 spiculiferous on both sides, finely pointed; third, a laterostigmatal series of large, cir- 

 cular, crateriform papillae or annuli, one in the centre of the first to sixth abdominal 

 segments, and a similar pai)illa on the seventh segment in place of the smaller and outer 

 subdorsal hair; fourtli, an iiifrastigraatalrow of smaller. but still pretty large jiapillae, 

 one in the centre of the first to eighth abdominal segments and immediately behind 

 them a minute, supplementary, posterior wart. Legs not very long, but moderately 

 slender, the last joint tapering, the claw pretty stout, not greatly curved. I'rolegs 

 nearly sessile, the circle of booklets very large, forming a circle or oval, open inte- 

 riorly, nearly as long as the segment and containing ten very minute, but not very 

 lender, moderately curving claws, separated from each other by a s -q ace more than 

 equal to their thickness. 



Mature caterpillar. Head small, smooth, well rounded, broadest just below the 

 summit, no Ijroader than liigli, very slightly full on the sides at the broadest point 

 and at the ooellar field, deepest in the middle l)ut scarcely narrowing above, the front 

 broadly rounded on a lateral view, the triangle large, scarcely higher than broad but 

 reaching two-thirds way up the front, the sutures a little impressed; a few hairs on 

 the triangle, labrum and lower part of the head. Auteunaelong, the basal joint promi- 

 nent, longer than broad, moderately stout, tapering, the second cylindrical, as large as 

 the apex of the first but only a little more than half as long as broad ; the third as 

 broad as the second, increasing a little in size at the apex, nearly twice as long as 

 broad, the fourth minute, conical, sharply pointed. Ocelli sis in number, four of which 

 are placed close together, the lower two a little more sepai'ated than tlie others, in a 

 strong curve, the arc of a small circle, its convexity forward, whose centre is occupied 

 by the fifth ocellus; the sixtli is placed belowtlieotiiers.alittleoutsideoftheextension 

 of a line connecting the lower two of the curve and as far from the lowest as that 

 is from its neighbor ; the central ocellus and the middle one of the anterior five are 

 the largest, the lowermost the next and the others equal. Labrum large, broad, 

 longitudinally rugose, its front border very broadly, roundly, and but little excised. 

 Mandibles slender, not broad, their edge oblique, very deeply dentate, the teeth being 

 long and very slender, tapering, sliarply pointed, rather distant, five or six in number, 

 and the space between adjoining ones roundly, deeply excised. Maxillary palpi with 

 the joints about equal in length, growing successively smaller, cylindrical, the terminal 

 conical; inner palp resemliliug the terminal joints of the outer but smaller; spinneret 

 conical, short, rather slender. 



Body regularly, equally and considerably arched from one extremity to the otlur : the 

 separate segments also rather prominently arched, especially in the middle of the body 

 and therefore quite distinct; viewed from above elliptical, the front end rounded a 

 little more bluntly than the hinder extremity, scarcely tapering posteriorly. Dorsal 

 field scarcely if at all depressed, but strongl)' arched and elevated on a cross section. 

 Body very delicately and closely shagreened, covered with numerous, irregularly scat- 

 tered, equal hairs, arising from nearly imperceptible warts, the hairs short, scarcely 

 tapering, bluntly pointed, frequently and minutely thougli coarsely spiculiferous, the 

 raised points scarcely directed toward the tip of the hair, but almost perpendicular to 

 the surface of origin. Spiracles small, obovate, more than half as long again as 

 broad. Legs short but rather stout, tapering rapidly, furuislied on the Inner 

 side with bristles, the last joint rather slender and appressed, the claw rather long, 

 compressed, heeled, moderately slender, curved a little, supported on either side by 

 a long bristle. Prolcgs very short and plump. furnLshed at the tip with a couple of 

 short pads, each supplied with 12-14 booklets, arranged in a double row so that all 

 those of one proleg form an open crescent; the booklets are long, moderately stout,
