Cassia siamea,Jjam* (Leguminosse). 



Larva. The larva [of G. catilla, Cramer] is very similar in every 

 way to that of Catopsilia crocale, Cramer [these two species are in 

 de Niceville's opinion one and the same species]. The head is round, 

 green, the clypens edged with brown, covered with small, shiny, black 

 tubercles which are not very large and do not hide the colour of the head ; 

 the anal flap is rounded, but looks square at the extremity, and is covered 

 with small tubercles, not black but green, each bearing a short hair ; the 

 body is covered with rows of small black tubercles as in C. crocale, of 

 which only the row along the spiracular line is conspicuous. The spira- 

 cles are oval, shiny and white. The colour is green, with a spiracular 

 white band touched with bright yellow on segments 2 to 5, and these 

 segments, especially 3 and 4, are distinctly flanged on the spiracular line 

 as in the larva of Hebomoia australis, Butler, though not to so great an 

 extent. Length 51 mm., height 7 mm. 



Pupa. The pupa is the same as that of C. crocale at first sight, 

 but the dorsal line of the thorax is absolutely parallel to the longi- 

 tudinal axis of the pupa for two-thirds of its length ; consequently the 

 hinder part just before the margin is perpendicular to this parallel 

 part, i.e., is raised suddenly though very slightly above the front margin 

 of segment 4, and the front end of this parallel dorsal line is at an 

 angle, and a sharpish angle, with the front slope of the thorax ; the 

 shoulder too is distinctly angled, i.e., the point where the lateral line 

 of the head and segment 2 meets that of the wings ; the front margins 

 of segments 9 and 10 in the dorsal line when looked at sideways show 

 a minute peak overhanging the hinder margins of segments 8 and 9 

 respectively ; the cremaster is distinctly bifid at the extremity, and has 

 some shiny, very short, black suspensory hooks dorsally as well as at the 

 extremity. There is a dorsal rugose black tip to the snout terminating 

 the head, which snout is cylindrical in its apical half ; there is no 

 black line round the eye as in C. crocale, and there is a dark green- 

 blue dorsal line, which is yellow on the thorax, as well as the supra- 

 spiracular yellow line. Length 34 mm., length of snout 3 mm., breadth 

 at segment 7 is 9 mm., height at apex of curve of wings (segment 6) 

 10 mm., height at the apex of the thorax 8 mm. 



[.^1 Habits. The habits are the same as in C. crocale in every particular 

 both as to the larva and the pupa. Mr. Bell notes that until the day 

 (30th July, 1898), on which he wrote this description he always
