I. Sikkim. 2 — 3. Nepal. 4 — 5. Lahore. 6. Benares. 7. Lingasugur, Deccan. 

 8. Madras. 9 — 10. Malabar. 11 — 12. Ceylon. 13 — 14. Penang (?). 



Habitat. India from the Nepal Valley and the base of the 

 Himalayas, Ceylon, Assam, Burma, and Southern Yunnan. 



The locality ' Penang,' attached to specimens from Cantor's 

 collection in the British Museum, is very doubtful, as in the case 

 of other specimens, probably from India, described by Cantor as 

 found in the Malay Peninsula. 



[The geographical range of R. tigrina extends as far north and 

 west as Peshawar, and I believe the base of the Baluchistan hills. 

 The few specimens I have seen from the extreme north-west of 

 India are, however, much duller in colour than those from Bengal 

 and seem to be in other respects intermediate between the forma 

 typica and R. crassa. Specimens from the Nepal Valley, beyond 

 the outer foot-hills of the Himala3'as, are typical. A^. A.] 



This species has a much wider distribution, extending toSiam, 

 China, and Tropical Africa, but the specimens from these outlying 

 countries deserve to be distinguished as races, which are even re- 

 garded by some as valid species. The four forms which I recog- 

 nize, one of wdiich, R. occipitalis, Gthr., is African, may be dis- 

 tinguished as follows : — 



A. Regular longitudinal glandular folds, 6 to 14 in number, 

 usually present on the back.
