moderately high but very much broadened. The mandible 

 is nearly 0-3 mm. in length. 



The palpi are nearly 0-39 mrn. in length. The extensor 

 surface of the first segment carries the usual curved spine. 

 The second segment is stout, nearly as thick as the first pair 

 of legs, and has on the inner edge of the extensor surface 

 four or five moderately long bristles. The flexor surface 

 may be straight or slightly bulging in its anterior half. The 

 characteristic long bristle is about as long as the segment 

 and stands well back from the anterior edge. The third

segment has six long bristles on its inner surface ; three 

 of these are distal, one being at the flexor edge and two 

 close together at the extensor edge. The other three 

 bristles are in the proximal half of the segment, one being 

 about midway on the extensor edge and one halfway 

 between that and the proximal extremity, while the 

 remaining one lies between these two but more in from the 

 edge. The fourth segment is weakly curved on its flexor 

 and extensor surfaces, and has two hair pores on the flexor 

 surface, equidistant from one another and from the extremi- 

 ties. The posterior hair is short, the anterior one very 

 minute. Towards the distal extremity of the extensor 

 surface there are two short hairs, and round the distal 

 extremity two or three others. At the distal edge of the
