Berlin Museum). Both forms belong to one and the same 

 genus. In structure they scarcely differ at all." 



In spite of this de Bormans attempted to keep the two 

 genera distinct. But an examination of a number of 

 specimens shows that the two Fpecies run into each other. 

 Dr. Kuhlgatz describes the head as black in D. longisetosa, 

 but it is not so in many specimen.^, as for instance the one 

 figured by Mr. Green (op. cit. PI. xviii, fig. 5). 



Hitherto this species has only been recorded from 

 Ceylon and Burmah, but in the Paiis collection I find two 

 females from Dardjiling which are so much larger and 

 stouter in build that I first regarded them as a distinct 

 species. But as I can find no structural distinction, I am 

 compelled to regard them as a local race or variety of 

 D. (jerstxckcri for which I propose the name var., calidam.

Diplatys rufescens, Kirb. 



In spite of its name, this species falls nearer to the 

 fuscous species than to the red D. gerstz&ckeri. It is most 

 closely allied to D. siva n,, but differs as noted in the table 

 of species.
