546 Mr. Edward Saunders on 



extreme edge of clypeus shining but not raised, bearing a few fine 

 hairs : inner orbit of each eye with a very small pale spot ; antennae 

 with the 3rd joint of the flagellum about three-fourths the length of 

 the 2nd : distance between the posterior ocelli equal to the distance 

 between each and the eye ; vertex with a very few long pale hairs ; 

 posterior margin of pronotum sharply angular in the centre, tegulae 

 pale testaceous, wing nervures brown ; wings very slightly tinged with 

 brown, with a broad apical dark brown band which stops just short 

 of the wing-cells, 2nd submarginal rather large, its lower margin 

 more than twice as long as its upper, and rather longer than the 

 radial cell ; coxae and femora all clothed with silvery pubescence, the 

 former especially densely and brightly, anterior tarsi with no ap- 

 parent comb, all the tibiae and the apices of the femora more or less 

 testaceous, the latter clouded with greyish-brown at the base, except 

 the posterior pair, which are testaceous throughout ; these and the 

 tarsi are also clothed with silvery pile, but not densely : tarsi testa- 

 ceous, their apices darker ; claws with a small tooth beyond the 

 centre ; calcaria pale, except those of the posterior pair, which are 

 nearly black ; abdomen more or less clothed with silvery pile, testa- 

 ceous as far as the apex of the 3rd segment, the rest black, apical 

 segment with a few very fine, inconspicuous hairs. 

 Long. 9 m.m. 



Although this is a single specimen, it is in such perfect 

 condition that I have ventured to describe it.

 does not quite reach the wing-cells, nervures brown, testaceous at the 

 extreme base ; 2 submarginal cells, the 2nd small, pentagonal, its inner
