Mote on the Coleopterous genus Cantharolethrus with descrip- 

 tion of the female of C. Luxerii : hy (Jhas. O 



Waterhouse. 



The British Museum has recently 1 »een fortunate enough 

 to add to the collection of Lucanidce, a female example of 

 Cantharolethrus Luxerii, and as it appears not to have been 

 noticed, I subjoin a description. 



Canth. Liuccrii, Buquet, ? . 



Elongatus, ater, velutinus. Capite thorocerpie granulosis 

 grannlis nitidis. Elytris ad humeros linea obliqua elevata 

 nitida. Long. 13^ lin., lat. 5^r lin. 



Head rather long, depressed, narrowed behind the eyes ; 

 the whole surface densely and very strongly punctured, 

 the interstices appearing granular and shining, the disk 

 with a large somewhat deep fovea behind. Thorax as long 

 as the head and mandililes together, nearly twice as broad 

 as long, narrowed in front, the front margin Insinuate, the 

 anterior angles very slightly prominent and obtuse, the sides 

 irregularly crenulate, posterior angles obliquely emarginate, 

 the angle in the side made Ijy the emargination prominent, 

 nearly rectangular; the posterior margin liexuous; the disk 

 with five shallow impressions which are with the rest of 

 the surface thickly and rugosely punctured, the raised parts 

 between the impressions shining. Scutellum shining, 

 strongly punctured. Elytra a little narrower than the 

 thorax narrowed towards the apex, dull velvety black ; 

 each elytron with a slightly olilique flexuous shining punc- 

 tured carina, extending from the shoulder to near the mid- 

 dle of the elytron. 



Hab. Bogota. (Mr. Chesterton, by whom the S was also 

 sent).
