 E. Ehves (' Ibis,' 1859, p. 397) and by Gould. But I need 

 not occupy your space by further instances. The charac-

 the shearwater, and can fit no other bird. In fact, he lias 

 discovered a veritable mare's nest.

LXXII. — Descriptions of Two new Species o/ Bactrododema 

 (Phasmidie) in the CoUeclion of the British Mwiemn 

 {Natural History). By W. F. KiRBY, F.L.S., F.E.S. 



In the first two parts of Mr. Distant's ' Insecta Transvaal i- 

 ensia ' I have described and fiijured a new species of 

 Bactrododema under the name of B. aculiferum (p. 17, pi. ii. 

 figs. 1, 1 a-c, 2, 2 a). I now describe two more closely 

 allied species from single male specimens. There are probably 

 a considerable number of curious Phasraid;\j belonging to the 

 subfamily Palophime inhabiting Africa ; but they are so well 

 concealed by their resemblance to dried sticks when their 

 wings are closed, that they are generally only observed by 

 some accident, and sent home singly. The sexes are so 

 dissimilar that it is useless to attempt to unite them, unless 

 insects wiiich are possibly or probably sexes are received in 

 the same collection, or unless there is some more definite 

 evidence pointing to their possibly belonging to the same 

 species. 



1. Bactrododema Lugardi, sp. n. 



Male. — Reddish brown, dusted with giey; antennaj very 

 pilose, reddish, the joints spotted with blackish ; ocelliferous 

 tubercles surmounted by reddish spines, the basal portion 

 shorter and stouter than the terminal portion, which is very 

 slender and bent backwards at an acute angle. Pronotuui 

 irregularly and longitudinally striated, with a slender black 

 line on each side. Abdomen reddish, indistinctly carinated, 

 unarmed. Legs unarmed, pubescent; front legs grey, indis- 

 tinctly spotted with darker ; four hind legs reddish. All the 

 tarsi brownish, the basal joint longer than the succeeding 

 ones together, and on the front legs strongly carinated and 

 slightly raised ; indistinctly carinated and hardly raist;d on
