 W'liite. 



Head broader than long, broadest near base. Eyes large, 

 somewhat coar.^elj facetted, pilose, occupying at least 0*5 

 the length of the head. A long stout genal spine behind 

 each eye; inter-ocellar and postocular spines rather long. 

 Mouth-cone reaching across prosternum ; maxillary palpi 

 long, apical joint shorter and narrower than either joints 1 

 or 2. Anttnuge more than twice as long as bead, first joint 

 with the characteristic prolongation described in the generic 

 diagnosis, which almost reaches the apex of the second 

 joint. Kelative lengths of joints 3-9 as follows: — 19 : 17 : 

 16 : 15 : 9 : 6 : 8. 



I'rothorax about as long as the head and 1*75 times as 

 broad as long ; furnished with several stout seta?, of which 

 the mid-lateral J)air, two at each hind angle, and certain

Hah. Western Australia, near Fremantle, on flowers 

 (nos. 17 and 22). The only named flower is a proteaceous 

 shrub [Dryandra floribunda, K. Bi.), and it is impossible to 

 say whether this species is attached to Dryandra (or any 

 other flower) or is a general species. 



I find particular pleasure in naming the species after 

 Prof. E. ii. Poulton, E.H.8., who obtained several other 

 interesting species on the occasion of the recent British 

 Association visit to Australia, and who has encouraged my 

 researches in many directions.
