70 Eev. T. A. Marshall's monograph oj 



is now in the National Collection ; and I have another 

 from the Forest Hills in Leicestershire.

2 . Piceous, castaneous, or rufescent, metathorax and abdomen 

 blackish ; 3 basal joints of the antennae rufous ; face, mouth, and 

 legs testaceous. Wings subhyaline, nervures and stigma pale ; 

 praebrachial nervure distinct. Antennae 18-jointed; 1st joint very 

 long, equal to the 10 following together; 2d obliquely inserted, 

 forming a geniculation ; 3d twice as long as the 4th; joints 3 — 6 

 filiform, the rest moniliform. Petiole of the 1st abdominal segment 

 hardly longer than broad, striated ; condylus much widened, 

 conical. Terebra not quite half the length of the abdornen ; valves 

 black. 



$ slender ; antennas a little shorter than the body, not genicu- 

 lated, 18-jointed ; 1st joint longer than the 2d and 3d together. 

 Otherwise like the ? . Length, \—\\ ! wings, \\ — 3 lin. 



As I have no specimen, the description is compiled 

 from the authorities, not without a difficulty arising 

 from certain discrepancies. Westwood gives the antennae 

 of the ? (from the Schetsen) as 17-jointed, and those of 

 the $ as 16-jointed. He further mentions that the 1st 

 joint in the $ is furnished with a small round tubercle 

 near the base, and that the 3d joint is produced beneath 

 into a deflexed spine at its apex ; these characters are 

 not represented in the figure by Van Vollenhoven, nor 

 mentioned by Euthe and Eeinhard ; so that it may be 

 questioned whether the English description does not 

 refer to a fresh species. 



Euthe possessed two males taken near Berlin, and 

 Eeinhard had a ? , of which he has given a figure. Two 

 English specimens of the $ are recorded by Westwood, 

 one from Glanvilles Wootton, in Dale's collection, and 

 the other preserved in that of Matthews, at Oxford.
