384 MESSRS. DIXEV, BURB, AND PICKAED-CAMBELDGE ON [May 3, 



n. OETHOPTEEA. 



By Malcolm Burb, F.Z.S. 



The Orthoptera collected in Socotra by Mr. Bennett are few in 

 number, bat not without interest. The new species of Pcecilocerus 

 represents a genus found in Northern Africa and in the western 

 part of Asia, and there is a new Cricket, of the genus Landreva 

 Walker, with a similar, but wider, distribiition. It is probable 

 that these two species are peculiar to the island, as they are not 

 migratory in habits, so far as is known, the Cricket at least being 

 incapable of flight. 



There is the usual percentage of cosmopolitan species, but the 

 collection is hardly large enough to give a fair idea of the relation 

 of the island to the neighboui'ing continents. 



A Locustid has been described, Pachi/siaoiwda albreviaia ' 

 (Tasch.), which is not found elsewhere, but was not taken by 

 Mr. Bennett. 



FOE-FICTTLARIA. 



Lajbidtjra bipaeia (Pall.). 



One male (No. 79). 



A cosmopolitan species ; originally apparently an inhabitant of 

 the Mediterranean subregion, also occurring in Java, Korea, South 

 America (coll. m.), Burmah, and North America. 



Blattodea, 

 Phyllodeomia sp. 



A very fragmentary example (No. 80), which resembles, but is 

 distinct from, the cosmopolitan Ph. germanica (L.). 



ACRIDIODEA. 



Texxalis nasuta (L.). 



One immature specimen (No. 81). 



This species occurs in Southern Europe, throughout Africa, 

 India, Burmah, and in Australia. 



AcEOTTLUS LONGiPEs (Charp.). 



The solitary example (No. 82) is a variety with the wings rosy 

 at the base, the normal colour being yellow. A blue form has 

 occurred at Zanzibar (Brunner). An inhabitant of South-eastern 

 Europe, Asia Minor, Abyssinia, and Zanzibar.
