STENETEIUM CRASSIMANUS, n. sp. 

 (Plate XX. A.) 



Whole body, in <? more so than $ , covered with rather long 

 hairs, which are especially numerous on the pleon. 



Antero-lateral angles of the head slightly bent inwards, teeth 

 forming the inner angles of the sockets for the second antennae 

 fairly prominent, rostrum longer than broad with blunt apex. Eyes 

 kidney-shaped. First segment of the peraeon rather longer than 

 the rest, its antero-lateral angles strongly produced. 



Lateral mai'gin of pleon with one tooth. 



First antenna, 1st joint largest, 2nd joint shorter than 3rd, much 

 shorter than 1st, flagellum not quite as long as peduncle, composed 

 of ca. 12 joints very indistinctly separated. 



Second antenna, 1st joint acutely produced externally, apex with 

 1 tooth and 4 setae, 3rd joint rather longer than 1st and 2nd com- 

 bined, exopod widening distally, 4th joint the shortest, 6th joint a 

 little shorter than 5th, flagellum a little longer than peduncle, with 

 many short scarcely separated joints. 



Upper lip apically rounded ; epistome with distal margin bidentate 

 in the centre. 



Lower lip, lobes with inner margin straight, outer strongly 

 sinuous, apices setose. 



Mandibles, cutting-edge 4-toothed, secondary cutting-edge in 

 left mandible 3-toothed, in the right probably represented by 4 

 serrate spines, spine-row in left mandible with 6 serrate spines and 

 one arising from base of secondary cutting-plate, in the right with 

 5 serrate spines ; molar strong and prominent, with tufts of setae 

 on posterior margin; palp strong, 2nd joint with 2 long serrate
