1900.] INSECTS AND ARACHNIDS FROM SOMALILAND. 35 



Gynacantha sp. ? 



One immature female from the same locality as the precediag. 

 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 Wattenwtl.) 



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 : —

 of species. ?sew Genera. K'ew Species. 



Blattodea 4 - - 



Mantodea 6 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 Phaneropteridai, 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 Euspoli has been published by Herr Dr. Schultes's 

 Eechberg-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 difiicult and obscure 

 species, especially for the determination and descriptions of the 

 Phasmatodea, upon which group his knowledge is unrivalled.
