On Acridoxena, a new Genus of the family Gryllidse. 309 



Other creatures of interest were exhibited ; the most im- 

 portant, however, belonged to the family of insects, and in 

 reference to the first of these, Dr Smith said — Unfortunately, 

 he could not get access to a copy of the " Fauna of the 

 Gaboon," published by Mr Thomson of Paris. If the curious 

 insect now exhibited be not described in that work, it does not 

 appear to be recorded in any work he had consulted, nor 

 does Mr Adam White, to whom he had shown it, know of 

 any figure or description of it. Mr White has kindly given 

 the following note, which will enable it to be identified: — 



" Notice of a n apparently Undescribed Species of Orthopterous Inject 

 of the Family Gryllidae, and other Insects from Old Calabar. By 

 Adam White, Esq. 



" This curious insect belongs to the group Camptoxiphce of 

 the section Locustariad> as characterised by Serville, in his 

 work on Orthoptera. In this group the oviscapt forms a 

 short, bent, broad blade. The present genus, of which I 

 have only seen a female, is allied to Phaneroptera, and has 

 some general points of agreement with the genus MarMa, 

 founded on the Phaneroptera hystrix of Westwood. (See 

 ' Museum of Natural History / ii. p. 244.) 



" Head large, simple ; eyes small, prominent. Labrum 

 large, rounded. 



" Prothorax with the lateral edge of its back six-spined, 

 the front two-spined ; the mesothoracic plate, square in front, 

 and deeply sinuated behind, edge projecting into a spined 

 lobe ; metathoracic plate wider than long, widely lobed 

 behind ; the lobes leaving a wide square notch, lobes spined. 



" Tegmina (in the female) sinuated on each of the lateral 

 margins, the posterior portion forming a broad lobe, rounded 

 behind. 



" Wings slightly larger than the tegmina ; the outer 

 margin sinuated and extending at the end into a narrow
