224 REVISION OF THE AMYCTERIDES, iii., 



(J. Size siiiallei', ii;irruuer. Clutliiug mostly of a slaty-grey, 

 with a large, subtriaiigular, dark })at('h on each side about the 

 middle of each elytron, apex of triangle almost touching suture, 

 and with an apical dark patch on declivity. 



5. More ovate, but with sijnilar clothing. D'uneiisioihs : (^, 

 1 1 X 4*5 mm.; 9, 1 1 x 5 mm. 



Hah. — Northern Australia, Port Darwin (A. M. Lea)^ — North 

 (Queensland, Princess Charlotte Bay (C. French). 



The head appears to be shorter, and almost nodulose in front, 

 though this is, to a great extent, obscured by the clothing; apart 

 trom this, there seems little difference in structure between the two 

 forms. The difference in the clothing is most conspicuous, and the 

 dark patches are constant in all the specimens (4) I have seen of 

 the variety. 



Type-male in Coll. Lea; type-female in Coll. Ferguson. 



N. ANGULicoLLis Lea, var. angustioh, n.var. 



Specimens from North- West Australia appear to represent an- 

 other variety of this species. 



(J. Size smaller, narrower. Clothing mottled with brown as in 

 type, without conspicuous, dark patches. Supraorbital crests 

 much smaller and less prominent. Dimeiisioiis : ^, 1'2 x 4 mm. 



Apart from its smaller size and much smaller crests, I can detect 

 no dilferenee between the variety and the type of the species. A 

 specimen which I also refer to this variety, is greatly abraded, and 

 shows small granules on the elytral interstices; these are generally 

 completely obscured by the clothing. Li both varieties, the angles 

 at the sides of the prothorax are less marked. Type in Coll. Fer- 

 guson.

I have little dou})t that the above species belongs to Notonophes. 

 The head is described as "sparsim granulato, supra oculos utrinque 

 cristato, crista rostri planum oblique retrorsum et extrorsum con-
