ANOCHETUS. 45 



the thorax and the apical margin of the mandibles are darlcer. 

 Head, tliorax and legs with sparse, the abdomen A\ith abundant 

 erect hairs. The head is much broader than the thorax and 

 the abdomen ; it is broadest in the middle, in the front much, 

 posteriorly less narrowed ; the lateral margins in front, as well as 

 behind the eyes, waved, and the posterior margin truncate with 

 projecting rounded angles. The eyes placed in the middle of the 

 sides of the head. The antennal carinas are arched and bounded 

 by the inner snargins of the antennal hollows, these are deep in 

 front, flattening out posteriorly. The clypeus in front is abruptly 

 truncate. The antennfe are slender, not very long. The mandibles 

 are at the base smaller and nearer together than at the apex, 

 which is bent at right angles and split into two large teeth on the 

 masticatory margin ; before the middle is a small, and after the 

 middle, nearer the apex, a much larger tooth. The head is entirely 

 smooth and shining, and only the space betx^een the antennal 

 hollows is longitudinally striate. The prothorax is much broader 

 than the rest of the thorax, rounded somewhat suddenly, con- 

 stricted anteriox'ly into a small neck, smooth and shining. The 

 rest of the thorax above is transversely striate or rugose, on the 

 sides smooth and shining. The node of the pedicel is conical, 

 with a somewhat obtuse spine above, and on the underside a 

 small tooth in front. The pedicel is inserted wholly under the 

 anterior face of the abdomen. This latter is oval, about as broad 

 as the prothorax ; its 1st segment is broader than long, anteriorly 

 somewhat smaller, and is ])lainly truncate behind and above the 

 rounded front face. The tibia3 are tolerably broad, and the claw- 

 bearing or apical joint of the tarsi is the longest ; the claws are 

 simple." {Rosier.)
