LANGURIIDAE FROM BURMA 261 



truncate as in some genera , but they are not simple as in 

 Languriaj Anadastus etc., the presence or absence of a minute 

 mucronate suturai angle is of the highest importance, and is 

 characteristic of this genus. 



Tliere are only two examples of this new species before me 

 and it will be noticed that it differs in many important points 

 from either of the descril)ed species, in the absence of a dilated 

 cheek in the female, in the puncturing of the whole insect etc. 

 But the two specimens are of moderate size, and it is very 

 probable that the insect is very variable in this respect and 

 that larger females may be more developed. 



The very fine species described by Fowler, C. exiuiia is at 

 present unique in my collection, it is a female and the left 

 cheek is much more strongly widened than the right one, 

 though the point is omitted in the description. I believe it was 

 collected by the late Mr. Gumming. Crotch's C. Wallacei, is a 

 unique female doubtfully of this genus, the elytra have their 

 apices truncate, but with a mucron at the external angle, the 

 eyes are very finely facetted, and the cheeks are not at all 

 widened. 



Coptolano-izria,, genus novum. 



Pedibas tarsis suhtiis s})on(jiosis„ latissime dilatatis, antennis ar- 

 tlcAilis sex primis fusi for mibus^ clava distincte quinque articulata. 

 Prothorux subqaadratus depressus, line is basalibus brevibus diva- 

 ricafis. Elijtris piinclato-slriutis , apicibus excisis , angulo exlerno 

 acute mucronato-prodacto. Abdominis segmentum ventrale basali , 

 lineis nullts. Oculi subliliter gi'anulati. 



This new genus is perhaps most nearly allied to Oxylanguria. 

 The tarsi are however as dilated as in Doubledaya. The cheeks 

 are dilated for the mandibles, but not asymmetrically in either 

 of the three examples. It is a synthetic type having much the 

 appearance of Goniolungaria. In my table of genera (Proc. Zool. 

 Soc. 1887, p. 301) it would be placed after Doubledaya in the 

 section (b) with Oxylanguria.
