 had changed to a uniform reddish brown color. 



rile cati'rpiUars alter the third molt are about i inch in lenj^rth, of a 

 fuscous color, and with the spines on the two superior rows on segments 3 to 

 \o, and the median one on segment 1 1, reil, with their terminal third black, 

 Kunple, fasciculate, thickly radiating from a black, slightly elevated tubercle, 

 the other spines are glossy black, Ijranched and whitish near their tips. 

 Spiracles linear and tawn\'. 



The caterpillars after their fourth molt are about i ^ i,) inches long, and 

 on emerging from the old skin, the head and all the spines are pale red. 

 After a few hours the head becomes a reddish brown and the spines their 

 normal color. The body is black, with numerous small whitish, oval 

 papillae, each bearing a short black hair. 



The larva after the fifth molt is about i y^ inches in length and the 

 superior spines on segment 2 have fascicular tawny, black tipped spinules, 

 like those of the two dorsal rows, encircling their base. On segments 3 to 



I I the lateral row of spines have similar fascicular spines bordering the 

 upper half of their base, as have also the two ante-superior spines of seg- 

 ment 12 at their anterior basal half. 



The full grown larva [pi. 17, tig. 8] measures from li,^ to 2}^ inches 

 in length. The head is red, round and bears a few short brown hairs. 

 The cervical shield is glossy and bordered anteriorally with four of the 

 eight spines with which the first segment is armed. The body tapers 

 moderately to the extremities, is fuscous and sometimes black, and is 

 sprinkled with numerous whitish ovoid spots, each bearing a short fuscous 

 hair. The two superior rows of spines on segments 3 to 10 inclusive are 

 fascicular, spreading over the anterior half of the segment, 30 to 40 in each 

 fascicle, c)lindric, tawny colored, tapering near their apex to an acute black 

 spine. The spines of the lateral row, the substigmatal and the ventral are 

 twice the length of the superior spines, of a glossy black color and tapering 

 trunk, with about 12 lateral c^■lindric branches of nearly equal length. The 

 spiracles are red, the anal plate a deep red, and with pitted surface and
