NOTES ON SOME NE UR OPTERA-PLA NIPENNIA DESCRIBED BY 
THE LATE MONS. A.-EDOUAED PICTET, IN HIS “NEVROPTERES 
D’ESPAGNE” (1865). 
BY R. McLACHLAN, F.R.S., Ac. 
I have had the opportunity of studying certain of the late A.-E. 
Pictet’s types, and subjoin the following notes : 
Sialis nigripes , Ed. Piet., p. 52, pi. iv, figs. 1 — 5. — I do not find 
any differences whatever between this and S. fuliginosa, Piet. (pere). 
The legs are not “glabres,” as is stated, but finely pubescent, as is 
usual. The size is very small (the $ sometimes expanding to only 
20 mm.). I have an equally small form of S. lutaria taken by the late 
Chev. Y. Ghiliani at a great elevation on the confines of Piedmont and 
Canton Valais. I regard S. nigripes as identical with S. fuliginosa. 
Chrysopa microcepliala (Brauer), Ed. Piet., p. 60. — The examples 
are no doubt specifically identical with Brauer’s insect. They are 
compared with Ch. alba in Pictet’s description, but the real affinity is 
with vulgaris, and I know that Dr. Brauer is now of opinion that mi- 
crocephala may be only a pale whitish form of vulgaris, which opinion 
I share. The former differs principally in the absence of reddish suf- 
fusion on the face, in a few of the basal nervules being slightly blackish 
at one end (those at the base of the costal area included), and in the 
dividing nervule of the third cubital cellule being often (not always) 
interstitiate with the nervule above it (instead of ending before it). 
Chrysopa nigro-punctata , Ed. Piet., p. 60, pi. viii, fig. 4. — Certainly 
a good species. Of the three examples one wants the spots on the 
mesonotum and metanotum (as is indicated by Hagen in Stett. Zeit., 
1866, p. 300), but has those on the pronotum. I saw a similar exam- 
ple from Barcelona forwarded by Sen. Cuni y Martorell. 
Chrysopa viridana (Schneider), Ed. Piet., p. 61. — I think there 
can be no doubt as to the identity of the examples with Schneider’s 
species, and Hagen is also of that opinion. Schneider’s types were 
from near Naples. Pictet found it at Grenada, and at Eaux Bonnes 
in the French Pyrenees. I have an example from near Quillan, Aude 
(Eaton). In this (as also in Pictet’s specimen from Eaux Bonnes) 
the costal nervules, &c., are not totally black, but have a pale median 
space. 
Chrysopa geniculata, Ed. Piet., p. 62, pi. vii, figs. 5 — 8. — I do not 
feel sure that this is anything more than a small example of viridana. 
Only one individual was found. 
Chrysopa Meyeri, Ed. Piet., p. 62, pi. viii, figs. 5— 8.— Of the two
