LIST OF BEITISH TIPVLIDM, he. ("DADDY-LONGLEGS"), 

 WITH NOTES. 



BT G. H. TERBALL, F.E.S. 



(Continued from Vol. xxiii, p. 267). 



L. APERTA, n. sp. (^ 5). — L. lineolellee simillima, sed pallidior et celluIA 

 discali apertdi,. 



This species is exceedingly like the preceding, and may possibly be only a variety 

 of it, yet there seem to be several small characters besides the conspicuous one of 

 the open discal cell. It is smaller, the dark line on the thorax is less shining, 

 smaller and shorter, the antennae are lighter coloured, the femora are usually less 

 black at their tips, the " great cross-vein " would be placed at about one-third the 

 distance from the base of the discal cell, were that complete, while in L. lineolella 

 it is at or beyond the middle, the forks of what should be the forked vein from the 

 discal cell are from one and a half to two and a half times as long as their petiole, 

 the mediastinal vein seems to end abruptly without any distinct cross-veins, but upon 

 minute examination the sub-costal cross-vein can be faintly traced close to the end 

 of the mediastinal, while the mediastinal vein itself ends faintly in the costa; the 

 sub-costal vein seems to end in a somewhat similarly abrupt way just before the 

 middle of the upper branch of the radial, but really it curves abruptly but evenly 

 into the costa, while a faint marginal cross-vein unites it to the vein below. The 

 end of the last abdominal segment of the male is deeply undulating at the side, 

 while in L. Uneolella it is nearly straight. One point in favour of this being a de- 

 pauperated form of L. lineolella is that further absences of venation sometimes 

 occur in it, one male in my possession having the upper third of the great cross-vein 

 absent on one wing and very faint on the other, while sometimes the tip of the upper 

 branch of the radial is obsolete. 



It is not at all uncommon, and extends from the south coast to 

 Suther] an dshire. 



L. ferruginea, Mg. : always easily distinguished by the entire 

 absence of any dark line on the middle of the thorax, and by the 

 portion of the radial vein (after the prsefurca but before the fort) 

 being just about the same length as the upper branch of the fork. 

 The abdomen of the male has a well-defined blackish fascia just before 

 the end, which occupies nearly all the last two segments ; on the edge 

 of the last segment of the belly are tufts of stoutish reddish-yellow 

 hairs. I have seen it in Hants, Sussex, Kent, Suffolk, and Suther- 

 landshire. 



L, ocTiracea, Mg., is a common species, easily known by the 



character in the table ; its distribution must be universal, as I have it 



amongst other places from Eonchurch, Inveran, Newmarket, and 

 Bantror.
