In North India both sexes are as a rule of a mncli l]riirht(T reddish tuwny 

 coh)nr than ('. tiifenoMrata. 



Genitalia. Male : The anal tergitc (x. t. : of figs, i and J, 0. trifenestrata *) 



is cleft at the apex, the two processes being jwiuted, a little curved downwards 

 and hollowed ont underneath. The anal sternite (x. St.) is a smooth brown ridge, 

 which widens centrally into a broad truncate lobe. The clasper (fig. «) is apically 

 divided by a sinns into two lobes, one apical (a) and the other ventral subapical (i), 

 both being rounded and, like the clasper, concave on the inside. The snbapical 

 lobe is placed tranversely to the plane of the outer surface of the clasi)er, presenting 

 its broad surface when viewed either from the api("il or the basal side of the 

 clasper. In ('. trifenestrata (fig, h) the corresponding lobe is always mure or 

 less in tlie same jjlane as surface of the clasper. The difference is easil}' perceived 

 without dissection by removing or brushing aside the scaling at the tip of the 

 clasper. Tlie most remarkable ditfercnce, however, is found in the chitinous ridge 

 which surrounds the base of the penis-sheath. This structure, which we termed 

 " penis-funnel " in lS98,-t- consists in Cricula andrei of a ring, which is widened 

 ventrally and here produced into two long cylindrical pale but hard processes, 

 which are flattened at the tip (p-f, fig. g). In C. trifenestrata there is always 

 a single central process instead of the fork (p-f, fig. h ; and figs. A — f). The 

 penis-funnel, moreover, bears on each side of the penis-sheath, and close to it, a 

 pointed process in the shape of a three-sided ])yramid {lo). The penis-sheath 

 itself (p) has in the Indian race on the right side, at some distance from the 

 apex, a black tubercle or tooth which is directed distad. This tubercle is also 

 present in C. trifenestrata (fig. i), but stands nearer the apex in that species, 

 and is never enlarged to form a pointed tooth. Within the penis-sheath there is 

 in the Indian race another armature, consisting of three pointed, and usually all 

 three distinctly serrated, black processes (love-daggers |), which are pushed out 

 with the duct during copulation, and doubtless serve as stimidatiug organs. Sucli 

 organs are found in the majority of moths. In one of the females of C. andrei 



such a process was lying in the copulation cavity. Female : The transverse 



chitinised ridge situated behind the genital orifice, and plainly visible as a rule 

 withont dissection, is centrally sinuate ; this sinus is about as broad as it is deep 

 in ('. iindrei, while it is always much narrower in <\ trifenestrata. 



Cocoon. Spun up singly or in twos or threes, not in large clusters ; pale yellow 



when quite fresh, fading into grey .after some time; opaque, with a variable number 

 of holes. 



Chrysalis. Less densely and less deejily jiuuctured than in C. trifenestrata ; 



the antennae and the upper lip somewhat broader. The last skin in the cocoon 

 easily recognised as that of C. andrei by the numerous black spines.
