CREMASTOGASTER. 139 



the metanotal spines broadly triangular at base, acute at apex ; 

 pedicel as in the , but the 2nd joint above has a rounded node 

 not very prominent and not divided either transversely or longi- 

 tudinally by a groove ; abdomen enormous, more than twice as 

 long and more than twice as broad as the thorax, very massive. 

 Head, thorax and abdomen of a deeper reddish yellow than the , 

 and finely granulate, opaque. 



Length, g 1-8-2-3 ; $ 5'5 mm. ( abdomen 3 mm.). 



Hab. Kanara(^fon); Dehra Dun (Smythies); Sikhim (Holler} 

 Ceylon (Green). 



The specimens from Kanara separated as var. aitkeni, Forel, are 

 more pilose, have the thorax striate-reticulate, subopaque, and the 

 metanotal spines divergent, not curved downwards. Specimens 

 from the Himalayas (var. symthiesi, Forel) are entirely yellow with 

 scarcely any brown on the abdomen ; the head and 1st joint of the 

 pedicel are square, the metanotal spines very long and divergent, 

 and the pilosity very sparse and short. 



This remarkable species of Cremastogaster is as aberrant in 

 habits as in the form of the $ . It makes no nests in trees as most 

 of the other species do, but lives in small communities under 

 stones.

$ . Dull brownish red or rusty, the antennae and tarsi paler, 

 the abdomen darkening to brownish towards the apex ; pilosity 

 pale reddish, sparse on the scape of the antennas and tibi, oblique. 

 Head longitudinally finely striate, opaque, the stria? divergent 

 posteriorly ; mandibles finely longitudinally striate ; clypeus 

 convex, anteriorly tranverse, ciliated ; eyes round, lateral, placed 

 about the middle of the head. Thorax opaque, somewhat narrow, 

 depressed ; the pronotum arched anteriorly, closely finely rugulose 

 granulate ; mesonotum and basal portion of metanotum laterally 

 margined, the former rectangular, longer than broad, slightly 

 transversely concave, rugose-granulate ; the latter broader than 

 long, longitudinally rugose, its posterior lateral angles armed with 

 two long backward-pointing spines which have a slight downward 

 curve: apical portion of metanotum nearly vertical, highly polished, 

 smooth and shining ; legs rather long, slender, finely punctured, 

 subopaque. Pedicel : the 1st joint broad and flat above, obtusely 

 rounded at the sides, and with a round, rather small tubercle at 

 its posterior apex above ; 2nd joint of pedicel very short, longi- 

 tudinally sulcate, the lateral portions rounded ; abdomen shining, 

 very finely punctured. 



Length, $ 3*5 5 mm.
