wrinkled prominence surrounded by a narrow groove. Tlie thorax 

 dorsally is smooth and rounded, laterally and dorsally blackish, the 

 rest of the ochreous or rufous tint noted above. There is a very 

 distinct narrowing behind the thorax. The legs and wings project 

 downwards in front in Lepidopterous manner, except that though 

 touching the abdominal segments they are free from them, the wings 

 extend to the 3rd, and the legs and proboscis to the 5th, abdominal 

 segment ; though this depends much on the fulness of the abdominal 

 segments. 



The meta-thoracic segment only shows a very narrow band. The 

 1st abdominal segment is more slender than the following ones. On 

 the anterior margin of its dorsal aspect is a row of sixteen tubercles, 

 eight to either side, with a narrow vacancy at the dorsal line, each of 

 these cari'ies a long rufous bristle, each nearly 3 mm. long, lying 

 adpressed and extending backwards to the posterior margin of the 

 next segment. The next six segments are different from the first, 

 but of a uniform type. The dorsal aspect of the second segment 

 (the first of these six) presents a transverse row of ten hooks, with 

 indications of two or three smaller ones at either end : each hook is 

 nearly a third of a mm. in length, is very sharp, its concavity being 

 backwards, the base of each hook extends backwards for about a third 

 of the width of the segment as a corneous ridge, and then throws up 

 a smaller reversed hook. In the centre of each space between these 

 ridges is a small tubercle supporting a short bristle, where the hooks 

 laterally become obsolete these bristles are stronger, to the number of 

 six on either side. All this dorsal armature is on a dark coloiu'ed 

 base. The lateral prominences each support four bristles of about 2 

 mm. in length ; the ventral aspect is tolerably flat, and on a dark base, 

 carries two long bristles on either side. 



The 3rd and 4th segments hardly differ from the 2nd, except that 

 the spines and hooks are a little less strong ; on the 5th they are 

 decidedly smaller ; on the 6th their complicated structure can hardly 

 be made out ; and on the 7th they are reduced to fine tubercles 

 ranging with those carrying the bristles — which in these segments are 

 stronger. The 7th segment carries sixteen strong bristles. Each of 

 these segments presents an indication of a spiracle immediately behind 

 the anterior portion of the lateral prominence, there is also an indica- 

 tion of a spiracle immediately in front of the origin of the wing. The 8th 

 abdominal segment is much smaller than the preceding ones, but carries 

 dorsally a transverse line of bristles and tubercles, the lateral bristles 

 are reduced to two, the ventral are not represented. The next segment
