the proximal end. The anal pro-leg on each side has two long, broad, 

 oblique bands, inclining anteriorly. 



The median dorsal line is marked with black dots which are arranged 

 as follows : 3rd segment, posteriorly, a small dot ; 4th, two very small 

 dots; 5th, 6th, 7th, 8th, 9th and loth segments, both fore and aft, two 

 large jet black dots. 



Between the dorsal and lateral tubercles, the arrangement is as fol- 

 lows : I St segment, one linear, transverse dash, posteriorly ; 2nd to loth 

 inclusive, both fore and aft, each two nearly circular dashes ; nth, one 

 posterior dash. 



Above the sub-lateral tubercles, exists another row. The 2nd and 3rd 

 segments have each one in front; 4th to nth inclusive, each one small 

 dot in front of a larger one. Below this row, between the pro-legs, there 

 is also a small dot on each of the several segments. 



Each of the ist, 2nd, 3rd, 4th and 5th segments, below the sub-lateral 

 row of tubercles, bears a single jet black tubercle, which is armed with a 

 single spine, or a pair of divergent, similarljr colored spines. 



The true legs are black, conical, 3-jointed, and armed with a single 

 black incurved claw. The pro-legs, with a semi-circular row of black 

 ciliae, inwardly. 



The head is lemon-colored, with two black, irregularly elliptical spots 

 anteriorly, resembling eyes, which have a small triangular shield between 

 them. There are also two smaller spots near the proximal end of the 

 3-jointed, conical antennse. The basal joint of the latter organ is sub- 

 truncate and lemon-colored ; middle, small, cylindrical, and concolorous; 

 and apical, setiform, hairy, and blackish. Upper lip,bi-labiate, greenish, and 

 black on margin. Jaws and lower lip similarly colored with the upper 

 lip ; palpi, 3-jointed, each joint being dark brown, with a greenish annulus 

 near their lines of union. 



Before moulting, the caterpillar assumes a bluish-green color. The 

 dots of the dorsal row become smaller, the posterior dots, partially or 

 entirely, disappearing. The tubercles upon the first segment become a 

 jet black ; dorsal tubercles upon the 2nd and 3rd segments, a reddish 

 purple ; lateral pair, a glossy black with bluish tinge at apex ; and the 

 others, a beautiful black. The remaining dorsal tubercles are deep yellow, 

 and have broad black patches on the sides, which are confluent posteriorly in 

 certain cases. Lateral tubercles, black on the inferior two-thirds, and
