BY ARTHUR M. LEA. 635- 



Yar. FUSCOTRiANGULARis, n. var. 



Two specimens (sexes) from the Mossman River dififer from the 

 typical form in having the granules much smaller, those on the 

 disc of the prothorax and apical half of the elytra almost or quite 

 concealed; the clothing less variegated, on the prothorax scarcely 

 forming longitudinal stripes, although a feeble transverse one 

 can be traced; on the elytra there are fewer blackish scales, but 

 there is a large indistinct brownish triangle extending from the 

 third interstice (which is rather more noticeably raised than in 

 the typical form) to the shoulder and margin, and terminating at 

 the middle on each side; the paler scales (which, however, are 

 not very pale) on the three sutural interstices are, therefore, not 

 interrupted at the middle, but extend almost to the base. The 

 suture, and almost the whole length of the posterior declivity, 

 are clothed with black scales, without the least trace of a v; and 

 there is a small elongate blackish spot on each of the preapical 

 callosities. The abdomen is almost entirely clothed with black 

 scales; in the typical form the darker scales are usually confined 

 to the middle of the third and fourth segments. 



I have described these two specimens as representing a variety, 

 rather than a distinct species, as the dentition of the femora, the 

 peculiar front tibiae of the male, and the structural characters 

 (other than the granules) are exactly as in the typical form.
