102 PROF. A. D, IMMS ON 



Legs. — Superior claws of the feet elongate and acuminate, with 

 two large slender proximal teeth ; in front of the latter are two 

 minute teeth, the distal one extremely small and situated just 

 behind the apex of the claw. The inferior dazvs flattened, bifid 

 at their apex ; resembling those of iSinella hbfti Schaff". (fig. 48). 

 Tenent hairs absent, their place being occupied by a slender 

 tapering seta. The legs are clothed with plumose compound hairs 

 similar to those fovind on the trunk, and among them, on the 

 inferior surface of the tibife, are spine-like setee (fig. 48). 



Furcida. — Equal in length to the antennae ; the manuhriimi 

 related in length to the dentes as 2:3; clothed on its dorsal 

 aspect with long plumose hairs. The mucrones resembling those 

 of >S'. hofti ; provided with a single stout and prominently curved 

 terminal tooth, and a basal backwardly directed spiniform tooth 

 (fig. 56). 



Coloration. — Entirely white. 



Length in adult examples 2 mm. ; in young specimens 

 1-1'5 mm. 



Two adult specimens and four young specimens ; taken in an 

 a.nts' nest under stones on a mountain-side near Badrinath, Garhwal 

 Himalaya, circa 10,300 ft. {A. D. Imms, May 27th, 1910).

This species is closely allied to Sinella hofti Schafi"., but differs 

 in the claws of the feet. It is readily separable from S. myrmeco- 

 phila Renter, which similarly occurs in ants' nests, by the 

 characters of the mucro and feet. 



The young examples differ from adult specimens chiefly in 

 having the first antennal joint proportionately shorter. 



Genus DiCRAN-ocENTROlDES, gen. nov, 



Mesonotum non prominens. Segmentum ahclominale quartutn 

 longius dimicUa parte trunci. Antennce dimidia corjjoris parte 

 longiores, quadriai'ticulatce. Ocelli 16 : 8 in titroque latere capitis. 

 Furcida latitildine apici fere cequalis. Dentes spinosi ; mucrones 

 lati dentic'idis armati. Cutis squamosa. 



This genus agrees with Bicraiiocentrus Schbtt in the dentes 

 being armed with simple spines, and in the length of the antennse. 

 "With Campylothorax Schott it agrees in the great length of the 

 fourth abdominal segment, in the form of the furcula, which 

 scarcely tapers in width up to the apex, and in the foi-m of the 

 mucrones, It is separable fi-om the latter genus on account of 

 the thorax not being flexed upon itself, and the relative shortness 

 of the antennpe.
