noticed it in the Ent. Ann. for 1862, p. 26. I always had a sus- 
picion that the insect was a true Phryganea, rather than an Agryp- 
nia, and at the last moment I fortunately received from Dr, Ha- 
gen types of P. obsoleta and A. picta, and have no hesitation in 
declaring my insect to be the furmer; 4. picta must, therefore, 
be erased from our lists for the present, but it is extremely likely 
to be found in the northern parts of this island. The two species 
bear very considerable superficial resemblance to each other, but 
A. picta is decidedly narrower-winged, and with the apex more 
sharply truncated (characteristic of the genus); the head is less 
transverse ; the markings are somewhat the same, but in 4. 
picta the small white spots are absent, and there is a dark fuscous 
spot on each side of the pterostigma, almost encircling it; there 
is also a fasciate brown band near the apex, which is not defined 
in P, obsoleta. The form of the appendices is altogether different. 
The published descriptions of both insects are too short to be of 
much service. P. obsoleta might be mistaken for a small and 
much faded example of P. varia, but the wings of the latter are 
decidedly longer and narrower in proportion ; the anal appendices 
of the males are also dissimilar, especially the app. sup., which 
are invisible or wanting in P. obsoleta.

Antennz testaceous, with fuscous annulations, the few first 
joints altogether fuscous. Head piceous, with greyish-ochreous 
hairs. Palpi fuscous. Mesothorax fuscous. Anterior wings 
fuscous, thickly spotted and irrorated with grey or ochreous grey ; 
on the costa the markings form large blotches, and on the inner 
margin short oblique streaks, the last of which forms a nearly 
complete fascia across the wing close to the apex ; there are also 
a few dark, almost black, dashes; apical margin regularly spotted, 
fuscous and grey alternating; neuration fuscous, Posterior 
wings smoky-grey, subhyaline; neuration fuscous, somewhat
