notum broadly triangular, narrowly rounded anteriorly, 

 smooth and shining, without parapsidal furrows. Median 

 segment with six longitudinal carinse, which are almost 

 parallel and are continued on the face of the posterior trun- 

 cation, the spaces between the carinas transversely striated. 

 First tergite elongate-triangular in the female, triangular in 

 the male, with a lateral groove on each side from the base to 

 beyond the middle ; second tergite with an impressed trans- 

 verse line behind the middle. Second abscissa of the radius 

 a little longer than the second transverse cubital nervure. 



Hob. Mackay, Queensland (Turner), February and March. 



This is the only Australian species of the genus known to 

 me, and no others appear to have been described, though 

 species of the genus appear to be fairly numerous in New 

 Guinea. The four genera dealt with in this paper appear to 

 be Malayan immigrants, and do not seem to occur in the 

 southern portion of Australia.

JEthechinus angolce, sp. n. 



General characters of AH. frontalis, but markedly smaller. 



Colour of the type about as in average examples of 

 dE. frontalis ; the dorsal spines tipped with whitish; the 

 crown, cheeks, and throat white, the belly black. Dorsal 

 spines about half whitish, then black, with a light tip. No 

 dependence can, however, be placed on colour, as not only 

 does frontalis vary enormously in this respect in single 

 localities, but, from what Bocage says, the same is evidently 

 true of angolce. The spines of the back are 19-20 mm. in 

 length, and those of the crown about 22 mm. 



Skull essentially as in frontalis, but smaller. The marked 

 longitudinal groove along the frontal suture, present in 

 every one of fifteen skulls of frontalis, is not, however, 

 perceptible in the type of angolce. There is also much less 

 distance at the sides of the nasals between the tips of the 

 premaxillary and frontal processes than is usual in frontalis. 

 The distance is only 2'2 mm. in angola, while it is commonly 

 6-6 mm. in frontalis. This is, however, a variable character 

 in all hedgehogs.
