The Aculeate Hymcnojptera of liarrachpirix. 95 



From this it will be seen that the Fossons are much 

 the strongest group, tliough it is only fair to state that the 

 number of species of MutUlichv, which help to swell the 

 total, is out of proportion to the specimens, and they have, 

 too, been much more closely collected than other families, 

 for there is always something irresistibly attractive to the 

 collector abont SlutiUa. 



Tij)liia and Myxiiu, on the other hand, are very poorly 

 represented, and both appear to affect northern, or at 

 least mountain, localities rather than the plains. 



The ScoliidiV, PompilitUv, and Sphcgidiv are all well 

 represented, both in numbers and species, many being 

 exceedinolv common and familiar objects of the bungalow 

 and compound, as also are several species of £umc niche and 

 Ves2}id;r. 



The Apidii- are the poorest both in species and numbers 

 in the Barrackpore district (they distinctly strengthen as 

 you go up-country to the 2sorth-\Vest Provinces at Allaha- 

 bad, and still more so at the Mussoorie Hills) ; and with the 

 exception ol Xyhcopa, a few species oi Jlcgachde, Crocisa, 

 and Antl(ophora, there are no species sufficiently common 

 to attract general attention ; and even with Xylocopa it 

 is more their great size, noisy booming ways, and the 

 brilliant effulgence of their Avings rather than their actual 

 numbers which makes them so conspicuous. 



In the Formicidii\ Gampanotus, CEc&pliylla, Prcnvkpi-i, 

 Diacamma, So/enapsis, Cremastogastcr, and Sima are most 

 in evidence, the three commonest species being Campunotv.s 

 com2nrssus,Soknopsisgclninata,2i^ldSiraarufonigra. Phcidolc 

 curiously is not so strongly represented as it is in the Bombay 

 and Madras Presidencies. Species of other genera are either 

 local and uncertain in their appearance, or really uncommon 

 and rare. 



I never came across any Ichneumoius in Barrackpore. 

 No doubt they are to be found if carefully sought for, 

 but they must, at least, be exceedingly rare. On the other 

 hand, in hill-stations hke Mussoorie and Darjeeling, they are 

 fairly common. 



Several species of ChrysididiV are not uncommon. 



I am greatly indebted to Colonel C. T. Bingham, for 

 his kindness in revising my list of FonnicidiV, and to Mr. 

 Peter Cameron for revising the Foss&res and Apkhv, etc. 



With very few exceptions, the types of all Mr. Cameron's 

 species are in my collection.
