512 Rev. T. A. Marshall’s monograph of 
as at the base, sessile, striolate, sometimes smooth at the extremity, 
or (in small specimeus) almost wholly smooth; the following 
segments smooth and shining. Terebra as long as the abdomen; 
valves stout, hairy. ¢ Antenne longer, 37—-4(-juinted ; 1st abdo- 
minal segment scarcely widened posteriorly, faintly striolate, or 
almost smooth. Length, 12-2; wings, 31-44 lin. 
Var. Abdomen piceous with the Ist segment rufescent and 
nearly smooth; legs paler piceous. 
Taken in England by Walker; in Ireland, rarely, by 
Haliday. Billups has captured it at Oxshott, and I have 
two which I captured near Abergavenny, and a third 
which I found at Nantua last summer, in the Jura. I 
have seen others from the Continent, taken in Italy and 
Germany.

Antennz 9? 25-jointed. Black, shining; mandibles pitchy red. 
Antenne stout, shorter than the body. Metathorax punctato- 
rugulose. Wings hyaline; squamula blackish-brown ; stigma 
blackish, stouter than in the allied species, confounded at the ex- 
tremity with the metacarp, emitting the radial nervure from near 
its middle; radial areolet not quite reaching the extremity of the 
wing ; recurrent nervure interstitial. Legs dull red; fore femora 
streaked with black at the base, the 4 posterior femora streaked 
throughout their whole length; tarsi, coxe, and trochanters 
blackish. First abdominal segment regularly striated. Terebra, 
according to Nees, half as long, according to Haliday a quarter as 
long, as the abdomen. ¢ Similar, according to Nees, but not 
described ; unknown to Haliday. Length, 14 ; wings, 3 lin. 
This species is unknown to me. MHaliday expresses a 
doubt whether his insect was the same species as the 
similis of Nees, on account of the difference in size, and 
in the length of the terebra. In other respects the 
descriptions of these authors coincide. 
Taken once in the London district, with A. man- 
ducator. .
