the sculpture of the median segment in the female less deve- 
loped, occurs in N.E. Rhodesia and Nyasaland: Luangwa

This is one of the most conspicuously coloured species of 
the genus.

segmentisque dorsalibus 1-3 fascia apicali pallide aureo-pubes- 
centibus ; area pygidiali fusco-ferrugineo-setoso ; alis pallidissime

Long. 14 mm. 
?. Clypeus shining on the apical margin and subtruncate. 
Second and third joints of the flagellum subequal; eyes 
separated on the vertex by a distance not quite equal to the 
length of the second joint of the flagellum. Thorax sub- 
opaque, smooth; median segment very little longer than the 
breadth in the middle, slightly convex, indistinctly trans- 
versely striated, with a low carina from the base not quite 
reaching the apex, the surface of the posterior truncation with

This belongs to the group of crwsus,Sm., but differs in the 
colour of the wings and legs, in the shorter tarsal comb, in 
the much sparser pubescence, and in the shorter median 
segment. ‘The pygidial area is similar to that of cresus, not 
truncate at the apex as in deceptor, ‘Turn.
