258 MR. B. m'lachlan on new species etc. oe neueopteka. 



longitudinally by lines of the whitish ground-colour in the middle 

 between the veins, the dark colouring consisting of a broad margin- 

 ing of the longitudinal veins, and in the apical fascia there are 

 several similarly margined transverse vienlets, hence this fascia has 

 a fenestrated appearance; before the first fascia are two or more 

 fuscous spots, sometimes uniting and forming a more or less complete 

 basal fascia ; between the fasciae there is generally a fuscous spot on 

 the dorsal margin, which sometimes unites with the first fascia, and 

 forms a little fork ; pterostigma yellow ; basal veins black, most of 

 those between the fasciae more or less testaceous ; the subcosta joins 

 the costa scarcely beyond the middle, far before the pterostigma. 

 Legs rufous ; claws with three obtuse teeth below the apex. Abdo- 

 men very long and robust ; the first four segments more or less trans- 

 verse, the lateral margins winged ; second segment with its postei'ior 

 margin above produced in the middle ; 5th segment nearly cylindrical, 

 longer than broad, scarcely narrower than the fourth ; 6th cylindrical, 

 about as long as the 5th, and narrower, truncated at the apex, the 

 apical margin produced at each side into a tooth ; 7th longer than the 

 6th and very much thinner, cylindrical, gradually thickened towards the 

 apex, which is truncated, with the margins slightly concave above and 

 beneath ; 8th short, broadly obconical, the forceps very long, the points 

 crossing each other, reddish brown. 

 5 . Much smaller than the <5 . In the specimen before me the basal 

 spots on the anterior wings form a fascia. Abdomen slender, the apical 

 segments very thin ; basal segments laterally winged, as in the male ; 

 two last segments equal, together not so long as the antepenultimate. 

 It is remarkable that in the neuratiou of all the three above- 

 described species, the subcosta joins the costa at, or scarcely 

 beyond, the middle, a pec\aliarity which, in the European species, 

 is seen only in P. variabilis.

I have seen a female of this ; the male is yet unknow^n.
