214 Mr. H. W. Bates on Longicorn 



Many examples. The males vary greatly in degree of 

 development of the antennae. In one small example 

 (6 lines) these organs are only about three times the 

 length of the body. In a fine male in Mr. Belt's collec- 

 tion, the proportion is five and-a-half times.

Several examples ; all have the anterior legs armed as 

 above described, and I cannot tell whether this is a 

 sexual character. The direction of the oblique dark 

 macular belt of the elytra is from the suture backwards, 

 to the margin, and. not from the suture forwards, as in 

 A. trivittatum, which is a widely distinct species in other 

 respects. 



This may possibly be A. adjundum, Thoms. (Physis. 

 p. 544) , but the description does not mention the chief 

 distinguishing points of the species.

A small number of examples. The tawny marks of the 

 elytra are indistinct, and variable in extent.
