 ►Sumatra ; Java ; Borneo. 



The specimens from Tenasserim represent the varietal form 

 {supra) ; those from the Malayan Islands are typicaL

This is a closely allied species to C, tricolor, and principally 

 differs in the follouiug characters : — The abdomen above is black, 

 with the segmental margins testaceous-red and a central longi- 

 tudinal series of small testaceous-red segmental spots, the apical 

 segment is ochraceous ; the tegmiua are spotted as in C. tricolor, 

 but the spots are ochraceous ; the tegmina are a little narrower 

 aud more apically pointed. 



It is questionable whether this may not prove to be another 

 varietal form of G. tricolor, \\ith which, as Butler writes, it was 

 formerly associated in the National Museum ; however, I possess 

 a long series of both and the markings are at least constant.

Hah. Andaman Islands {de Roejjsiorff). — Cambodia, Laos 

 {Brit. Mus.). 



I possess four specimens of this species from the Andaman 

 Islands. The specimens on which Butler founded the species were 

 collected in Cambodia and Laos by Henri Mouhot.
