Mr. John Edward Gray on Cheirotonus Parrii. 59 



XVII. Description o/ Cheirotonus Parrii, a new Species of 

 the Family Euchiridae. By John Edward Gray, Esq., 

 F.R.S., &c. 



[Read 7th June, 1847.] 



Having recently acquired a pair of a species of the genus Cheiro- 

 tonus from Northern India, and Captain Parry having kindly 

 brought his specimen of the male of Ch. Maclean to the Museum 

 for comparison, I have been induced to draw up the following 

 distinctive characters of the two species. 



Cheirotonus Macleaii, Ho-pe. 



Brassy green, with large yellow spots 

 on the elytra. 



Front of the femur of forelegs angu- 

 larly produced in the centre. 



Tibia of forelegs very long, strongly 

 curved, and sharply bent inwards at the 

 end, with a subcentral elongated spine 

 above, and a similar spine at the end ; 

 oblong, rather compressed, with a few 

 scattered asperities on the upper sur- 

 face, and with two minute spines on the 

 lower outer surface. 



Thorax punctated with a triangular 

 slight impression in the middle of the 

 front edge. 



Scutellum polished. 



Cheirotonus Parrii, Gray. 



Brassy green, the elytra marbled with 

 yellow. 



Front of the fensur of forelegs with a 

 small spine on the middle. 



Tibia of the forelegs moderate, very 

 slightly arched, with two similar spines 

 above, subtrigonal, with scattered aspe- 

 rities on the upper surface, and with 

 three spines on the lower outer edge. 



Thorax deeply and coarsely punc- 

 tured, with a small angular projection 

 in the middle of the front edge. 



Scutellum deeply punctured. 



Mr. Westvvood, in describing Capt. Parry's specimen (Cabinet 

 Oriental Ent. p. S,) observes, that at the extremity of the tibia 

 '' there is a small thick moveable spine." I suspect that Mr. 

 Westwood has mistaken a slight notch in the upper surface for a 

 joint ; for the terminal spine is exactly similar to the one near the 

 middle, and as continuous with the rest of the tibia.
