sinuous course, and ending on the side of tlic head. There is a V-shapted 

 yellow patch on the clypeus, which also sends an obscure yellowish line 

 outward, in a course ])arallL'l to the line above. The labrum is pale ; the 

 face very hairy, as is the whole head. The body is dull, dark manganese 

 or iron-brown. There is a dorsal, obscure, median, irregular, reddish- 

 brown line ; also two dull-yellow, nnrroxo lines on each aide of the body, 

 the upper one of the two being the subdorsal one, and more or less 

 stained with reddish. There is an obscure, broken, yellowish line along the 

 base of the legs bdow the dark spiracles. The prothoracic segment is 

 slightly swollen on the sides. The dorsal hairs are short and fine, but 

 along the lower part of the face, and ahrng the side of each thoracic and 

 abdominal segment, is a swelling from which arise dense, long, pale-gray 

 hairs directed downwards, much as in Gastropacha. The thoracic and 

 anal legs are dark livid, and the body beneath is livid. The surface of 

 the skin in general is rough and rather dull in color. 



Stage IV. — Molted August 25 and described a few hours after. In 

 the larva of the previous stage the left (?) anal leg was injured and 

 shorter than the other; this defect was retained after this and the last 

 molt. 



Length, at first, 17 ram. The head is now larger in proportion than 

 before, being a little wider than the body ; it is somewhat bluish brown, 

 with the markings as before, but much more distinct ; the two parallel 

 lines on the vertex not so difl'use and reddish as before, but nearly black, 

 and each enclosing a lanceolate-oval, distinct, fleshy, whitish spot of the 

 same color as the two sets of transverse, sinuous lines below. The face 

 below is pale carneous ; and on the sides and in front more densely hairy 

 than above. 



The body is of the same shape as before, still tapering to the end. 

 Along the body extends a dorsal, reddish-brown, diffuse line as before, 

 but a new system of markings appears in this stage, consisting of a set of 

 four small light dots, two on each side of the dorsal median line. Tlie pro- 

 thoracic shield is now very distinct and concolorous with the head, and 

 the segment is slightly wider than those succeeding, while the lateral, 

 prothoracic, piliferous warts are still small. The subdorsal stripe is con- 

 colorous with the single dorsal one, but the lateral and infraspiracular 

 line at the base of the legs are now more yellow ; otherwise the bodj"- in 

 general is dark brown as before. On the end of the seventh and eighth 

 abdominal segments are two pale-yellowish spots, and on the base of the 

 suranal plates are two dark-yellow spots ; the surface of the plate itself is 

 concolorous with the prothoracic shield. All the legs are dark. The 

 hairs low down along the side of the body are whitish gray, dense and 

 depressed, partly concealing the legs, especially the middle abdominal 

 ones. 



Stage V and Last. — Molted September 4. Described September 12. 

 Length, 82 mm. The head is as before. There is now visible, when the 

 larva creeps, what had not been noticed in the preceding stages, viz., a
