 Cyclommatus vitalisi Pouill., Iiisecta, iii, 1914, p. 335, fig. 5.

Bright yellow, with the head reddish in the female, brown, 

 with a greenish metallic lustre in the male, the pronotum with 

 the front and hind edges, the middle line and a lateral patch 

 on each side black (with metallic suffusion in the male), the 

 elytra with the shoulders and the imier and outer edges 

 narrowly black. Tlie antennae and tarsi also black and the 

 greater part of the legs and lower surface of the male dark 

 metallic green. The elj^ra rather more elongate than those 

 of C. strigice.ps. 



?. Like that of C. strigiceps, but lighter in colour and more 

 shining above, with the head strongly punctured, the pronotum 

 strongly but not very closely, except at the sides, and the 

 elytrd rather closely but not densely. The lower surface has 

 a slight metallic suffusion ; the metasternum is very finely 

 and sparsely punctured and the abdomen closely. 



(J. Like that of C. strigiceps, but the head and mandibles 

 darker, with a very distinct metallic sufi'usion ; the pronotum 

 has a dark lateral patch on each side, also with a metallic 

 sufi'usion, and the elytra are a little paler in colour. 



Variation of the male. I have seen only well -developed 

 specimens of this species, which appears to attain a rather 

 larger size than C. strigiceps. All the specimens have six or 

 seven well-marked longitudinal folds on each side of the head. 

 No doubt small examples closely resemble those of the related 

 form.

Type in the ])eutsche Entom. Inst., Dahlem, Berfin ; that 

 of vitalisi in M. Rene Oberthiir's collection. 



This is very closely similar to C. strigiceps but api)ears to 

 have a different and wider range. The female is easily 

 recognized by the more shining up})cr surface and the male 

 by the more metallic head and thorax and the dark lateral 

 patches u])on the latter. In specimens from Tonkin (C 

 vitalisi) the corrugation of the sides of the head of the male is 

 not very distinct, but I cannot regard them as specifically 

 ditt'erent. A thiid closely related fi)rin in the Mala}' IVninbula 

 is C. pahangcnsis Nagcl.
