than the prothorax at the base, arcuately narrowed behind, 

 moderately strongly and rather closely pimctate-striate, the inter- 

 stices narrow and very slightly raised ; the humeral angles very 

 slightly produced ; the sides feebly reflexed. Legs with the femora 

 dark ferruginous brown, the tibiee and tarsi much paler. Length 

 13-14 mm. ; greatest width 4| mm. 



Port Darwin, North Australia ; Richmond River, New South 

 Wales. 



This fine species, which is the lai'gest Brontes known to me, can 

 be separated at once from all the Australian species by the form of 

 its head and prothorax and by its having the elytra somewhat 

 convex. The Richmond River specimen in the Macleay Museum 

 is rather darker in colour than the other individual.

After a careful comparison of a long series with specimens which 

 I named from Mr, Pascoe's types, I have little hesitation in stating 

 my conviction that the two forms bearing the above names are 

 merely extreme varieties of one species. In the series now before 

 me the spines on the prothorax vary considerably in size and shape, 

 the punctuation of the elytra is less regular in some of the larger 

 specimens and the colour of the individuals from Clarence River 

 is much darker than that of the others.
