20 MANDIBULATA. HYMENOFTERA. 



Te. furcata. Fillers. — Sch. furcatus. Steph. Catal. 327. No. 3771. 



Head and thorax black, slightly shining; abdomen dull yeilowj with the basal 



segment dusky or blackish; legs luteous; femora black at the extreme 



base; wings hyaline, fuscescent; palpi also luteous; antennae black and 



ciliated in the male. 



A rare insect, and I believe not found within the metropolitan 

 district; the only specimens I have seen having been taken in 

 Somersetshire, in the vicinity of Bristol, in June. 



Sp. 2. pallipes. lEneo-niger, nitidus, antennis nigris, tibiis tarsisque pallidis, 

 alls hyalinis fascia ohscura substigmate pallide fuscescente. (Long', corp. 2§ 

 lin. ; Exp. Alar. 5 — 5i lin.) 



Cry. pallipes. Leach. — Sch. pallipes. Curtis, v. ii. pi. 58. — Steph.' Catal. 327. 

 No. 3772. 



Head, thorax, and abdomen shining brassy-black; femora dusky-black, tibi« 

 and tarsi pale ; wings hyaline, with a faint brownish fascia annexed to the 

 stigma, which is fuscous ; antennae black, faintly ciliated in the male. 

 Apparently very rare : I have taken both sexes at Coombe wood in 



June, and the females at Birch wood, but I know of no other 



locality. 



§ 3. Antennce many-jointed, with a double series of pectinations beneath in the 

 males; thickened towards the middle, with the apex acuminated and 

 somewhat serrated within in the females; anterior wings with 1 ample 

 marginal areolet and 4 submarginal ones, the 1st of the latter sometimes 

 incomplete; body broad, depressed. 



Genus IX.— LOPHYRUS, LatreUle. 



Antennas composed of numerous distinct articulations, the 2 basal ones straight 

 and simple, the remainder placed obliquely, and in the males producing on 

 each side a long ciliated ray, gradually decreasing in length to the apex, 

 the 3 or 4 terminal joints having but one ray, and the extreme one being 

 simple ; in the female they are thickened in the middle, and slightly serrated 

 within : mandibles tridentate : head transverse, wide in the males, small in 

 the females : ocelli 3 : wings ample, anterior M'ith 1 marginal and 4 sub- 

 marginal areolets, the first 2 of the latter with the divisional nervure 

 imperfect : abdomen broad, depressed in the females : legs simple ; tibice 

 with a pair of acute spurs at the apex only. Larva with 16 prolegs. 

 There is considerable disparity in the sexes of this genus, but each 

 may be readily known from the other genera of this family, by the 

 antennae alone ; in the males these organs are strongly bipectinated 

 (as in many Lepidoptera), the pectinations, or rays, diminishing in 

 length to the apex of the antennae, the terminal joint being simple ; 

 in the females they are thickened in the middle, and slightly atte-
