Larva.* First stages greenish yellow, tubercles of the same colour ; last 



stage bright green with the tubercles red ; the two dorsal tubercles of the eleventh 

 segment united, in the first stages black, in the last stage reddish and placed 

 on a green prominence ; the bristles stonter than in C. trifi-nestrata, in first 

 stages pale with dark tips, in last stage with black tips or quite black, central 

 bristle of each tubercle more or less prolonged, on segments 1 — 4 and 10 — II 

 ending in a long twisted filament. First stages with six rows of black spots ; 

 last stage without spots, but with a pale lateral line and numerous minute white 

 grannies, evenly distributed, each bearing whitish hairs ; these hairs so thin that 

 the body appears naked, apart from the setiferous tubercles. Head black or 

 lirownish green, immediately after ecdysis of the colour of the body. 



Food-plants : oak, plum, blackthorn, etc. 



We know the species from North India and Java, our specimens representing 

 two geographical races : 



a. Cricula andrei amlrei. 



S ?. Very bright tawny, reddish tawny or ochraceous, as a rule much brighter 

 than C. trife nest rata. The transjiarent spot of the hind wing of both sexes is 

 larger than in C. trifenestrata. The female has at least one small transparent 

 spot in the cell (at the proximal side of the large spots). 



A series of both sexes in the Tring Museum from Sikkim, Bhutan, and 

 Assam. 



Type of name : cJ from the Khasia Hills in Assam. 



b. Cricula atidrei elaezia snbsp. nov. 



S. Olivaceous clay-colonr, without any rufescent tints. Forewing darker 

 olivaceous on disc ; in front of the round transparent spot a row of three minute 



transparent dots, -Underside : the grey scaling and the grey lines more jirominent 



than in C. trifenestrata. 



Clasper as in C . andrei andrei (penis-funnel destroyed by an accident) ; 

 penis-sheath much thinner than in C. andrei andrei, without armature on the 

 out- and inside. 



Only one specimen known : Uradjad, 0. Kendang, Preanger, Java (ex coll. 

 van de Poll). 



In spite of the difterences in tlie strncture of the i)enis-sheath, I cannot but 

 regard this Javan insect as a form of 6'. andrei. The genitalia vary to .some extent 

 also in the geographical races of C. trifenestrata.

This species is known to ns from Ceylon, South and North India, Burma, the 

 Malay Peninsula, the Andamans, Snmatra, Java, Lombok, Borneo, and Luzon, and 

 may have a still wider range. The imago occurs, presumably in all places, in a

 will he published at a future date, when our observations are more complete.
