Catascopus cingalensis. 



C. faciaU et C. angidato affinis, sed differt capite post oculos sxilco 

 transverse impresso ; subviolaceo-cyaneus, capite thoraceque sub- 

 viridi-cyaneis ; frontc propc oculos sicut in 0. faciali confuse 

 rugato, vertice subtiliter punctulato ; elytris apicc extus brcvis- 

 sime acute dentato, apice suturali obtuse subrotundatim producto, 

 punctato-striatis, interstitiis 1-4 a^(]ualibus, plauis, quiuto angus- 

 tiore parum elevato, septimo angustissime cariuato ; tborace sicut 

 in C. angidato, angulis posticis rectis reflexis. 



Long. 12-14 millim. 



Kandy and Balangoda. 



Differs from all the numerous varieties of the widely-distri- 

 buted C.facialis and C.angulatus in the more sharply im])ressed 

 transverse groove behind the eyes. The groove is, however, 

 not so sharply impressed as in G. cequatus. The eolour of 

 the elytra is not a rich violet, as on the disk and, in Assamese 

 examples, over the whole surface of G. facialis^ but a dullish 

 steely violet, with a faint seneous tinge perceptible on the 

 borders. In one of the two examples the outer tooth of the 

 elytral truncature is extremely small ; this seems to ap])roacli 

 the insect described by Chaudoir erroneously as G. reductus, 

 Walker, but it differs in the fifth elytral interstice being not 

 carinated.
