ON THE TENTHREDINIDJ] & PARASITIC HYMEN- 



OPTERA COLLECTED IN BALUCHISTAN BY 



MAJOR C. G. NURSE. 



By P. Cameron. 



Part I. 



{Read before the Bombay Natural History Society on25th January 1906.) 

 Up till now our information regarding the Tenthredinidce and 

 Parasitic Hymenoptera of Baluchistan has been a complete blank. The 

 collection, small though it is, made by Major Nurse at Quetta and 

 Peshin, forms a welcome addition to our knowledge of the Hymen- 

 optera of that part of our Indian Empire. As we know practically 

 nothing about the species inhabiting North- West India, of Afghanistan 

 ou the north and of Persia on the west of Baluchistan, it is useless to 

 discuss the geographical relationship of the species. It may, however, 

 be remarked that the affinity of the species appears to be with the 

 Palsearctic, rather than with the Oriental Zoological Region. The 

 occurrence of a species of Nematus (a large and typical Palaearctic 

 and Nearctic genus, and found, too, only commonly in the northern 

 parts of these regions) is very interesting. The occurrence of the com- 

 mon European Ichneumon, Bassus Icet'atorius, Fab., is not of much 

 importance in deciding the geographical affinities of the Baluchistan 

 species ; for the reason that it has now spread itself (probably in 

 comparatively recent years) all over the globe, following its host, some 

 wide ranging Dipteron, no doubt. 



The species in the collection are of small or medium size. The 

 large species of Ichneumonidce (Ichneumon, Amblyteles, &c.) appear 

 to be comparatively rare. Undernoted is a summary of the 

 collection : —
