Group B 



Head smooth-scaled 



21. Genus CERACE, Walker 



Cerace. Walker, List Lep. Het. Brit. Mus. Vol. aH, p. 422 (i863). — Ty()e : C. stipatana. Walker. 

 Pentacitrotus. Butler. UL Lep. Het. Brit. Mus. VoL 5, p. 35 (i8Ki). — Type : C. vulnerata, Hutler. 



Characters. — Head smooth-scaled. Antennae in (^f ciliated. Palpi short, porrecteiL second 

 joint shortly rough-scaled, terminal joint very short. Thorax without crest. Forewinps without costal 

 fold, 3 from angle, 7 separate, to costa. Hindwings without basal pecten ; 3 and 4 connate 01 approxi- 

 mated at base, 5 more or less approximated to 4, 6 and 7 closely approxiniated towards base. 



Remarks. — This and the next tive genera constitute an interesting naturai group, se|)arahle 

 from all the rest of the family by the smooth head, and remarkHble for their striking colouration. 

 It represents a short line of special development, and I had at one time proposed to separate it as a 

 distinct family Ceracidae, but now think this undesirable; the relationship to Cacuecia and Torlrix is close 

 in all essential particulars. Cerace is a development of Megalodoris, but differs fioni all ils immediate allies 

 by the peculiar modification of the form of the forevvings, the real apex being obliterated and a false one 

 formed lower down, so that vein 7 and sometimes also 6 and even 5 appear to terminate in the costa. 

 Some of the species are the largest of the family. 



Geographical distribution of species. — Principally indian, hut exteuding to China and 

 Java.
