10 SECOND YARKAND MISSION. 



rufo-fuscous ; beneath, the pro-ancl metathorax and also the legs castaneo-rufous. Abdomen, 

 subglobose ; the scale and petiole, and the two basal segments castaneo-rufous, their apical 

 margins black, the second most broadly so ; beneath, these segments are entirely castaneous. 

 Female, length 5 lines. 



Sab. Sind valley, Kashmir. Taken in August. 



25. CAMPONOTTJS BACCHUS. 



Femina. C. capite abdomineque nigris, metathorace pedibusque pallide ferrugineis.

In the same bottle in spirit a male ant accompanied the female ; its size and general 

 appearance justify me in considering it to be the male of C. Bacchus ; it is 4J lines long, 

 black, with the antennae and legs pale furruginous, the scape being darker than the flagel- 

 lum ; the mandibles, palpi and post-scutellum are also pale ferruginous ; the wings flavo- 

 hy aline ; the nervures pale rufo-testaceous ; the stigma fuscous. 



Sab. Jhilam Valley, Punjab Hills. Ceylon, Calcutta, and Islands of the Eastern 

 Archipelago. 



This genus is cosmopolitan ; its species are numerous, new kinds occurring in almost 

 eveiy collection made in little frequented places ; any attempt to calculate the number of 

 species would be an impossibility ; until each species has been collected from its nest, and all 

 the different kinds of sexes carefully ascertained, the number of specific forms cannot be ascer- 

 tained ; workers of several sizes and forms occur in nests of many species, and if captured 

 at large, are doubtless described as distinct ; the number of species doubtless amounts to 

 hundreds. 



26. FORMICA SIMULATA. 



Operaria. F. rufo-femtginea, Icevissime cinereo-micans ; fronte vertice et abdomine 

 nigrofmcis ; squama subtriangulariter rotundata, tnargine supero rotundato ; area 

 frontali opaca. 



The head red, with the vertex and the front, as far as the insertion of the antennae, 

 more or less rufo-fuscous ; the clypeus with a longitudinal sharp carina in the middle ; its 

 anterior margin rounded and entire ; mandibles ferruginous, with their teeth black ; the 

 antennae ferruginous, with the flagellum, beyond the third joint, fuscous. Thorax and 

 legs bright blood- red. Abdomen covered with fine cinereous pile; in some examples 

 fusco-ferruginous at the base ; with a few scattered pale setse ; the scale of the peduncle red, 

 its superior margin rounded. Worker, length 3 lines. 



Hab. On the road across the Pamir, from Sirikol to Panja ; also at Yarkand ; April 

 and May. 



This species closely resembles the Formica sanguinea of Europe, particularly small 

 workers of that species ; the specimens were collected in spirit ; therefore it is probable the 

 entire insect would, when living, be covered with a fine pile.
