Species of the 2nd Section of Peeicoma 



(Analytical Key, Steps 3a, 2, 1). 



1 — — Eringe of the wing's apex light coloured or whitish ; that of the posterior 



margin uninterruptedly dark 2. 



a — Fringe of the wing's apex whitish or cream colour ; that of the posterior, 

 margin dark, with a patch of white in at least one place. Wing, ovate, or 

 elongate-ovate, subacute 5. 



2 — (1) Posterior branch of the pobrachial nervure linked by a perpendicular cross 



veinlet to the stem near its abrupt inner extremity. Legs dark coloured, 

 with light coloured hair at the apical margins of the tibia and of the 



joints of the tarsus 3. 



a — Posterior branch of the pobrachial nervure either continued to the stem, or 

 linked at its inner extremity to the stem by an oblique or curved cross 

 veinlet 4. 



3 — (2) Superior $ appendages apparently 1-articulate at first sight, subglobular 



and slightly compressed, with an acicular spine directed towards the tip 

 of the penis ; this spine, the 2nd joint, is curved sharply and tortuously 

 towards its origin in the inferior base of the spheroid 1st joint, and 

 where it] begins to be straight, is propped up by a short laminar lobe 

 directed backwards, which arises in close proximity to the upper part of 

 the inner base of the spheroid. Marginal dark spots at the ends of the 

 wing-nervures less distinct than in the next species. Wing, 3 to 3'5 mm. 

 long 8. P. neglecta, sp. nov. 



a — Superior $ appendages obviously 2-articulate, geniculate ; 1st joint stout, 

 longer than broad ; 2nd joint elongate, subulate, and curved. Marginal 

 hair-spots at the ends of the wing-nervures blackish, small, but distinct. 



Wing, 3 to 3"75 mm. long 9. £. canescens (Meig. ?), Schiner. 



4 — (2(z) Tibia and last three joints in the tarsus dark coloured or blackish ; 2nd 

 tarsal joint and the base, if not all, of the 1st joint glossed dorsally with 

 whitish. Fringe of the wing's apex cream colour from just before the 

 cubitus to just within the posterior fork ; small flaxen hair-spots at the 

 ends of all the nervures, except the cubitus and the prsebraehial. Basal 

 joint in the superior $ appendages tapering upwards ; 2nd joint longer, 

 uncinate, dilated in its basal half and then pointed. Wing, 2 to 2*5 

 mm. long .. 10. P. exquisita, s^^. r\o^. 



a — Tibia and tarsus from most standpoints blackish, with a whitish gloss on 

 the extreme apical margin of the tibia, and of the next one or two joints 

 in the tarsus ; but from certain directions the last three tarsal joints 

 appear black, and the first two take dorsally a dull whitish gloss in the 

 (J , or a dull dark greyish gloss in the $ . Fringe of the wing's apex 

 cream colour from just before the cubitus to the anterior branch of the 

 pobrachial nervure. The flaxen hair-spots in this species are less distinct 

 than their counterparts in P. exquisita. Basal joint in the superior <J 

 appendages stout, rounded, compressed ; 2nd joint short, uncinate, 

 folding down obliquely into the former. Wing, 2'25 to 275 mm. long. 



11. P.fallax, sp. nov.
