are placed dose tugethei', three-jointed, and slightly longer than 

 the mandibles. The basal joint is short and njoderatelv narrow, 

 the second longer, broader, and somewhat fusifoi-ni, the third 

 long, very narrow and seta-like The lal>' nvi (Ir) is merely a 

 weak, slightly bifid projection betw^een, and slightly above, the 

 mandibles. 



The head itself is curiously elongate, the black eye-spots being 

 placed lateralh' close up to the anterior border. The atitrmnr 

 {ant) are situated just in front of the eye-spots, above the man- 

 dibles, and closely resemble the labial palpi. They are, however, 

 longer, and four-jointed. The basal joint is short and fairly 

 thick; the second joint is somewhat bioader and slightly fusiform 

 as regards its distal two-thirds, but the basal third is narrower, 

 and the outer border is slightly dentate or ridded at one-third 

 from the base; this ridging probably repiesenting the beginning 

 of the formation of a number of small segments from this joint. 

 The third joint is long and \ery slender, the fourth merely a 

 sharply-pointed, seta-like tern)i nation. The iieck or niicrothorax 

 (nic) is very conspicuous, elongated and rather narrow.
