closed in front, on the right side there is a short additional groove 

 closed in front ; but the outer groove is widely open in front. On the 

 Belgian Museum specimen the left side is as in the type, whilst the 

 right has one deep groove only, but the ridges separating the 

 grooves are forked hindwards, so that there appear to be two short 

 additional grooves. The shoulder and third interstice are strongly 

 produced at the base, so that this appears to have four tubercles 

 projecting on to the prothorax. The posterior declivity has six 

 tubercles overhanging it, the largest of these, on each side, being 

 on the second interstice, the next is on the third (and sometimes 

 apparently conjoined with that on the second) and the outer one on 

 the fifth. The tubercles are not elevated, but appear as if the inter- 

 stices had been continued so as to overhang the declivity. 



A specimen taken by Mr R. Helms on Mount Kosciusko (at an 

 elevation of 5-6,000 feet) appears to be a female of this species. It 

 differs in being larger, elytra wider and more convex, tubercles 

 smaller, apex feebly l)imucronate, and under surface without a 

 hairy ridge; these being features in which it would be expected to 

 vary sexually. But its head has only three strong impressions, 

 although there are traces of others; it also has a very fine carina 

 along the middle of the rostrum; so that it should perhaps be 

 regarded as a variety.

(161). AMORPHORRHINUS AUSTRALIS Germ. 



A specimen labelled « Austr. int., Waterh. » differs from the nor- 

 mal form of this species in being smaller (7 mill.), with the forehead 

 conspicuously grooved, the lateral cephalic tubercles smaller and 

 more acute, the rostral carincie more acute, the prothoracic ridges 

 more acute and irregular, and the elytra with more numerous 

 granules. It may represent a variety, and a second specimen (wit- 

 hout locality label) agrees with it in most respects. Australis, 

 however, is such a variable and widely distributed species, that it 

 does not seem advisable to attach a distinct name, even as a variety, 

 to these two specimens.
