IS very 



and this causes the humeral one, in most Anycterides, to be 

 strictly speaking the fifth ; while the infra-humeral interstice, 

 called by Sir William Macleay the fifth, should be considered as 

 the sixth. 



Genus Talaurinus. 



There are eight species in the collection that may be referred 

 to the genus Talaurinus, and, as far as I know, none 

 closely allied to any previously described species. 



Four (T. regularis, T. solidus, T. Relinsi, T. wqualk) are allied 

 species showing a relationship to the "granulate" section of the 

 genus ; their sculpture is, however, much rougher than any 

 " granulate " species known to me ; they might be regarded as 

 forming a separate (rougldy-gramulate) group. Though quite 

 distinct species, all agree in general appearance, form of rostrum, 

 and conformation of under-surface in both sexes. 



The fifth species (T. crassicepsj seems quite 8?ii generis. 



The thi-ee remaining species (T. obscurus, T. noctis, T. 

 insignis), with a fourth species here described, but not belonging 

 to the Elder Expedition collection (T. convexus), are aberrant 

 species that I cannot place in any of Sir William Macleay 's 

 sections of the genus ; they are more allied to T. rugiceps, Mad, 

 than to any other previously described species I have seen. T. 

 noctis, T. insignis, and T. convexus have obvious affinities to the 

 genus Sclerorhinus in the form of the rostrum and the conforma- 

 tion of the under-surface. It seems to me that the division of 

 the Amycteridm into genera founded chiefly on the form of the 

 rostrum is too artificial to be much longer maintained. When a 

 more natural system comes to be adopted it is probable these 

 species will be removed from Talaurinus. 



Talaurinus regularis, a. sp. 



Oblong, very robust; prothorax granulate; elytra .striate, the 

 interstices regularly granulate. Black, the granules shining ; 

 spaces between the granules filled with fine cinereous scales, these 

 thicker on elytra and forming a stripe along their margin ; 

 under-surface witli cinereous-yellow scales down middle of \-eiitral 

 segments. 



Rostrum short, narrower than head, deeply excavate, trans- 

 versely impressed between external ridges at base ; external 

 ridges setigero-punctate, diverging a little in front, internal 

 ridges obsolete — merely short jDrocesses of posterior-half of 

 external ridges. Head broad, short, convex ; front a little flat- 

 tened behind rostrum ; occiput with cinereous pilose scales. 



Male. — Prothorax a little broader than long (-5 x oj- mm.), 

 lightly and regularly convex transversely, lightly dilatate on 

 sides, widest a little before the middle ; disc very lightly convex
