I have only seen one specimen of this species, and 

 that unfortunately in a bad condition. In Ireland, ac- 

 cording to Templeton, it is very common. The head is 

 small ; the thorax is not distinct from the abdomen ; 

 the prothorax cylindrical ; the mesothorax is enlarged 

 and elevated ; the metathorax is less raised, short and 

 broad. The abdomen is 10-jointed and tapers gradually 

 backwards. 



The eyes which are large, compound, and black, meet 

 in the middle line. The antennce are shorter than the 

 body, but in my specimen were imjDerfect at the ends ; 

 they differed, however, considerably from Templeton's 

 figure 1 c. The terminal whip-like portion is divided 

 into much more numerous subsegments, which towards 

 the end become monihform, have each a whorl of hairs, 

 and fall into groups of seven, each group separated by 

 a well-marked division. 



The larger palpi are 6-jointed, the three basal seg- 

 ments point forwards, the third being smaller than the 

 other two : the three terminal ones are recurved, and
