the $ are armed with an apical spine on each side, and the 

 seventh also with a narrow central spine, segments beneath 

 clothed with grey hairs, third slightly produced in the 

 centre, ? with a dense golden scopa; legs more or leas 

 variegated with yellow, densely clothed with long some- 

 what silvery, shining hairs, intermediate and posterior 

 metatarsi in the ,$ longer than the tibiae. 



L. 11-16 mm. 



Abundant in some localities, but chiefly in the Southern 

 parts of England, it has occurred in Scotland where it is 

 very rare, but has not been recorded from Ireland. It 

 appears about the end of June, and is particularly partial

 as the first, third and fourth divergent, very small, short and 

 cylindrical, paraglossse exceedingly long, filiform towards 

 the apex, longer than the labial palpi, maxilla with a 

 slight hook at the apex, their palpi six-jointed, labrum 

 transverse, antennas in the S nearly as long as the entire 

 insect ; thorax densely hairy, wings with two snbmarginal 

 cells; six ventral segments exposed in the (5', armature

Of this genus there is only one British species, although 

 the number of European species is considerable ; it often 

 forms large colonies, burrowing in the ground. Smith 

 savs " their burrows are usually about six inches in length ; 

 at the end of eacli an oval chamber is excavated ; it is
