112 Rev. T. A. Marshall's monograph of 



infumated, with a whitish streak under the stigma ; squamuhe 

 rufous ; nervures stout, fuscous, rufo-testaceous at the hase of the 

 wing; stigma fuscous, its inner angle rufous; recurrent nervure 

 rejected ; 'id ciibital areolet narrowed towards the radius ; 2d 

 abscissa of the radius distinct. Metathorax convex, coarsely 

 rugose. Tracheal grooves distinct. Legs stout. Terebra longer 

 than \ the abdomen. $ J . Length, 2 — 2| ; wings, 3} — 4^ lin. 



Head as broad as the thorax ; face almost twice as wide as long, 

 not narrower below, not carinated, punctulate ; above the clypeus 

 is a shining oval protuberance ; mandibles tipped with fuscous. 

 Antenme J § of the length of the body, filiform, 22 — 25-jointed ; 

 of the cT longer than the body, setaceous, 28 — 32-jointed, not paler 

 at the base of the nagelhun. Thorax less robust than in the last 

 species, coarsely sculptured, the priescutellar fovea large and deep, 

 bisected by a carina. Sides of the prothorax gibbous, rugose, as is 

 also the furrow of the mesopleurae. Metathorax not elongate, 

 regularly convex, somewhat excavated behind, coarsely and irregu- 

 larly reticulato-rugose. Abdomen as long as the head and thorax, 

 more attenuated behind than in albicornis, segment 2 more 

 brightly rufous ; segment 1 about \ of the whole length of the 

 abdomen, widened suddenly at the tubercles and thence more 

 gradually to the apex, which is about 4 times wider than the base, 

 striolated ; tracheal grooves elongate, conspicuous ; segment 2 

 seldom entirely black, rufous at least anteriorly, even in the $ ; 

 segment 3 also sometimes rufescent at the base. Terebra exceeding 

 \ or f of the abdomen ; the valves black. The infumated wings 

 are rather narrow in both sexes, and reach but little beyond the 

 anus ; 2d cubital narrowed towards the radius, but not so much as 

 to destroy the 2d abscissa. Hind tarsi entirely, the others at the 

 apex, fuscous. 



Described from ten females, three males. Common. 

 Taken at Maldon by Fitch ; by Thurless near Norwich ; 

 by Capron near Guildford ; by me in Birch Wood, near 

 St. Albans, Abergavenny, Teignmouth, &c. According 

 to Haliday frequent in Ireland.
