THE CARABIDAE OF BARKUDA ISLAND. 



By H. E. Andrewes. 



I give below a list of some 36 species submitted to me for 

 determination. I have not been able to put names to all of them, 

 because, owing to the war, I have not yet had the opportunity of 

 seeing various t^'pes in the Museums and collections on the continent. 

 The Carabidae of Barkuda Island do not appear to offer any special 

 features, and most of the species are widely spread through India 

 and Ceylon. Perhaps the most interesting insect taken is the 

 example of Scarites terricola, Bon., a northern form of which I 

 have seen no other Indian specimens. A series of Comsodiscus 

 picturatus, Andr., was taken, of which species only two other exam- 

 ples have hitherto been found elsewhere : nothing is 3'et known of 

 its life-historj' or habits. I describe a new genus Vclinda for an 

 insect taken at Barkuda, of which by the same mail I received a 

 second example taken by Mr. E. A. D'Abreu in the Central Prov- 

 inces ; it lives under bark and careful search will no doubt pro- 

 duce other examples.

With the single exception of 0. dissors, Tchitch. (on which 

 further light is requiied), the genus is peculiar to India and Ceylon ; 

 the species are numerous and many are still undescribed. 0. costa- 

 tus is widely spread in India and is variable both in the amount 

 of puncturation on the ventral surface, and specially so in the 

 sculpture of intervals 2 and 4 of the elytra. These may form well 

 developed ridges, like the other intervals, or thej' may be reduced, 

 even to the extent of disappearing altogether. In the specimens 

 before me these ridges are reduced but quite distinct, and the size 

 of the insects is a little less than that of the type.

The occurrence of this well-known palaearctic species in sub- 

 tropical India is very unexpected, but I have compared the exam- 

 ple with specimens from China, Japan, and Southern Europe, and 

 do not feel any doubt about the identification The only other
