252 Rev. T. A. Marshall's monor/raph of 



rounded and truncate at the apex; 2 scarcely longer than 3, 

 which last is somewhat shining, although distinctly subrugulose 

 and vaguely punctate ; the other segments very smooth. Second 

 cubital areolet almost complete. Spurs of hind tibite stout, longer 

 than I the metatarsus. ^ . Length, 1^ ; wings almost 4 lin. 



Distinguished from the two preceding by having testa- 

 ceous squamulse ; with them it has little affinity, except 

 the sculpture of the 3d segment. The antenna are very 

 stout, compressed, and, though broken, still nearly twice 

 as long as the body. The abdomen is unusually small ; 

 belly pitchy-black, with a yellow pellucid streak on each 

 side beneath segments 1 — 2 ; segment 1 is narrowly 

 edged with yellow, 2 more broadly ; 3 is much less 

 coarsely sculptured than 1 — 2, but cannot be regarded as 

 smooth. Legs elongate, stout ; middle tibife longer than 

 their tarsi, their spurs as long as the metatarsus ; spurs 

 of the hind tibiae very stout, shorter than the meta- 

 tarsus. Anal forceps exserted, pale testaceous. Areola 

 complete, except at the outer lower angle. 



One specimen taken in Scotland by Cameron.
