 in North Madagascar.

Distribution. Only two defective specimens were taken at Farquhar, 30 Sept. 

 Certainly this species was imported from Madagascar, where found by M. Charles Alluaud 

 on "Montague d'Ambre." 



To supplement the description given by Dollfus, I.e., I add a few essential characters ; 

 I also give drawings of other characteristic and instructive features.

Seychelles Archipelago ; eight specimens, all females, were collected at Mahe, at an 

 altitude of 1600 feet. 



This species is obtained also in Madagascar and seems to be widely spread over the 

 countries within the warm zone. I have never seen a male specimen of this species. 



24. Nagara nana. 



Nagara nana Budde-Lund (5), p. 285, Taf 14, figs. 40 — 47. 



Seychelles Archipelago: one specimen was found at Praslin, dry hills; in the museum 

 of Paris is also one specimen from Praslin. Chagos Archipelago : two specimens from 

 Egmont, and four specimens from Coin, Peros. 



Formerly, this species was only known from Madagascar ; lately I have seen 

 specimens from Java (Buitenzorg 24. IL and 2. III., Tjibodas 25. III. 04, Prof K. 

 Kraepelin in Mus. Hamburg), Singapore (Mus. Hamburg), Ceylon at Mahavaligaiiga 

 (Dr G. Duncker 16. VIII. 09, in Mus. Hamburg), Formosa at Takao (Dec. 07, Mr H. 

 Sauter in Mus. Hamburg). The species seems to be widely spread.
