The leiTs and prolegs are rufous, and three hours after the molt the larva 

 had changed to a uniform reildish brown color. 



The caterpillars after the third molt are about i inch in length, of a 

 fuscous color, and with the si)ines on the two supfTior rows on segments 3 to 

 10, and the median one on segment 1 1, red, with their terminal third black, 

 simple, fasciculate', thickly radiating from a I)l:ick, slightly elevated tubercle, 

 the other spines are gloss)- black, branched and whitish near their tips. 

 Spiracles linear and tawny. 



The caterpillars after their fourth molt are about i/io inches long, and 

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

 After a''fe\v hours the head becomes a reddish brown and the si)ines their 

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

 papillae, each bearing a short black hair. 



The larva after the hfth molt is about i ^^ 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 

 II 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 I pi. 17, tig. 8j measures from ili to 2% inches 

 in len-th. The; head is red, round and bears a few short brown hairs. 

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

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

 moderatelv 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 .0 inclusive are 

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

 fascicle cvlin.lric, tawny colored, tapering nc-ar their apex to an acute black 

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

 twice the length of th,. superior spines, of a glossy black color and tapenng 

 trunk, with about 12 lat.^ral cvlindric branches of nearly ecp.al length. he 

 spiracles are red, the anal plate a deep red. and with pittc.! surface and
