Gynacantha sp. ? 



One immature female from the same locality as the preceding. 

 This in all probability represents a new species, but I am not dis- 

 posed to describe and name a species of this very critical genus 

 from an immature female. It appears to be quite distinct from 

 any West-African species. 



7. OETHOPTERA. 

 By Malcolm Burr, F.Z.S., F.E.S. 

 (Except Phasmatodea by Dr. C. Brunner von Wattenwyl.) 



The collection of Orthoptera made by Mr. C. V. A. Peel in 

 Somaliland is not large, but contains examples of a good number 

 of genera and species new to science. These are distributed as 

 follows : — 



Number 

 of species. New Genera. New Species. 



Blattodea 4 - - 



Mantodea 6 1 1 



Phasmatodea 3 1 2 



Acridiodea 15 1 2 



Locustodea 11 1 7 



Gryllodea 4 - -' 



Total 43 4 12 



It will be noticed that there are no less than seven novelties 

 out of the eleven Locustodea captured, a high percentage, which is 

 probably due to the stationary habits of these insects. Most of 

 these new species are Phaneropteridas, for there are only one 

 Conocephalid and one Stenopelmatid, both of which are flightless 

 forms. 



The collection contains no Forficularia. 



An account of a collection of Orthoptera made in Somaliland by 

 the late Prince Buspoli has been published by Herr Dr. Schultess 

 Rechberg-Schindler. They are mostly of the same genera, but the 

 species are different. This is especially noticeable among the new 

 forms. 



I take this opportunity of acknowledging my deep indebtedness 

 to Herr Dr. C. Brunner von Wattenwyl, for his invaluable assist- 

 ance in the identification of many of the more difficult and obscure 

 species, especially for the determination and descriptions of the 

 Phasmatodea, upon which group his knowledge is unrivalled. 



Blattodea. 



PhYLLODROMIID-E. 

 ISCHNOPTERA ATRA Walk. 



Somaliland (April 16 to Aug. 7, 1895, or June 5 to Oct. 29, 

 1897). One male.
