PSYCHE. 



[November, i(>o2 



rather larger, on the third segment and 

 one bifid, larger, yellow tubercle on the 

 eleventh segment. Part of the dorsal 

 tubercles, on the abdominal segments, 

 were yellow, part black, and part were 

 yellow ringed with black. There was 

 no regularity in the distribution of color- 

 ing, the yellow tubercles being some- 

 times on one side, sometimes on both, 

 sometimes opposite, sometimes at one 

 end, sometimes at the other, sometimes 

 more on one side than on the other. 



After the third moult the head was 

 yellow with two black spots, and some- 

 times two black dots. The body was 

 almost white, the first and last segments 

 being yellow. The first segment had 

 six black tubercles, shaped like cynihia s ; 

 the second segment had two large 

 yellow tubercles ringed with black on 

 the dorsum and two smaller black 

 ones on each side ; the third segment 

 had two large yellow dorsal, and four 

 smaller yellow tubercles ringed with 

 black, and the abdominal segments were 

 like this e.\cept the eleventh which had 

 one large dorsal tubercle of yellow, and 

 the other four tubercles smaller, yellow 

 ringed with black ; and the anal segment 

 which had two rather large tubercles, 

 yellow ringed with black, on the dorsum, 

 one black one on each side below these, 

 and two black ones on the anal plate. 

 The legs were yellow, the props yel- 

 low with a black spot, except the anal 

 props whicli had the black triangle 

 characteristic of promethea. 



One larva had the dorsal tubercles on 

 the second segment smooth and shaped 



like those of promethca^ the others had 

 these tubercles like cyiitkia's. 



After the fourth moult the head was 

 small, yellow with two small black marks, 

 and in one case a black bar across it. 

 The body was pale blue-green with white 

 bloom, except the first and anal seg- 

 ments, the former being yellow, the latter 

 very yellow green like that oi promethea. 

 The dorsal tubercles on every segment 

 were long and shaped like promethea' s 

 thoracic tubercles in most cases, though 

 a few had abdominal dorsal tubercles 

 shaped like Cynthia's. These dorsal 

 tubercles varied much in color, some 

 being pale coral-red, darker on the tho- 

 racic segments and growing paler to the 

 eleventh segment ; others being pale red 

 on the first six segments, yellow else- 

 where ; others pale red on a few seg- 

 ments and green with yellow tops on the 

 rest. Some had the thoracic dorsal 

 tubercles ringed with black at base, 

 others had all the dorsal tubercles so 

 ringed ; while others had black rings 

 irregularly distributed, not even on oppo- 

 site tubercles on some segments. 



The other tubercles were like cytithia's, 

 pale blue ringed with black. The legs 

 and props were yellow with a black dot 

 on each. Two had the anal plate edged 

 with pale blue, like cynthia's, and one 

 had this edge almost purple. 



One larva had the dorsal tubercles, 

 from the eighth to the anal segment, 

 pale coral-red at tip and vivid yellow- 

 green at base, and the two dorsal tuber- 

 cles at the top of the anal plate vivid 

 green with a broad black ring on each.
