the Genus Raphidia. 495 
3. Raphidia media, Burm. 
R. media of Schneider and Rambur are identical according to the 
types. 
12 to 15 antecubitals, and usually 5 discoidal areoles, marginal 
veins almost all twice-forked; areole beneath the pterostigma as 
in A. notata. R. angustata of Ratzeburg belongs here, according 
to a type. 
Male.—Penultimate abdominal segment very short, the parts 
inserted beneath larger, very strong, triangular when viewed from 
the side, cylindrical and straight when viewed from beneath, the 
apex obtuse, with a little curved tooth within, two brown crotchets 
above before the apex; penis stout, black, convex above, triangular 
at the sides. 
Female.—Last ventral segment slight, produced at the apex, 
truncated obliquely at the apex if viewed from the side. 
4. Raphidia xanthostigma, Schummel. 
Schneider, after an examination of the type of Rambur’s cog- 
nata, of which the head is wanting, thought that species identical, 
probably erroneously, for he did not examine the genitals. The 
wings of R. xanthostigma are larger and more rounded than in 
betica and hispanica. The areole below the pterostigma begins 
and ends at the same points as the pterostigma, and only by ex- 
ception begins later or sooner ;_ the subcosta finishes always very 
slightly before the pterostigma in the costa; the second vein in 
the posterior wing is not simply furcate, but one branch is again 
forked. R. chalybocephala, Ratzeburg, seems to be identical, ac- 
cording to the type. 
Male.—Penultimate segment half as long again as broad, above 
with a very short apical excision, beneath broadly divided for the 
insertion of the penis, which is brown, slightly shorter than the 
segment, canaliculated, rounded at the apex; the sides of the 
segment rounded at the apex above and in the middle of their 
border, with a brown, acute, slightly-curved crotchet, scarcely 
longer than the segment. Terminal segment yellow at the apex, 
broader than long, open beneath, forming a quadrangular lobe 
when viewed laterally. 
Female.—Last ventral segment quadrangular, truncated at the 
apex (fig. 2, post, p. 499). 
5. Raphidia affinis. 
According to Schneider the areole beneath the pterostigma is 
NN2
