232 Mr. McLachlan on species of Chrysopa 
latter, and in some other species, there is a tendency 
to the flattened and dilated tibiz above alluded to. In 
the example from Shahrud the basal joint of the antenne 
appears to be blackish beneath. 
(Postscript. Since this paper was read, I received 
from my friend the Rev. A. E. Eaton twelve examples of 
C. nana, taken by him on June 8rd, 1893, at Biskra, 
Algeria, sitting on oil-lamps in the Jardin opposite the 
station from 8 t0 10 p.m. In this long series the black 
irrorations on the wings are still more strongly marked 
(no doubt due, to some extent, to the specimens being 
comparatively fresh). The expanse of wings varies from 
144 to 19 mm. In the anterior wings there are more 
frequently 2 than 3 gradate nervules in the inner series 
(sometimes only one), but nearly always 8 in the outer 
(occasionally only 2). Mr. Eaton remarks that ‘“‘ its 
eyes were a sort of metallic blue-black, not coppery like 
those of other species.”’| 
Chrysopa lineolata, McLach., Ent. Month. Mag., xvii., 
p. 64 (=C. clathrata, Kd. Pict., nee Schneider). 
I have before me eight examples from Vernet-les- 
Bains, and one of Ed. Pictet’s types of ‘‘ clathrata” from 
Granada. That author also records it from HKaux 
Bonnes in the Pyrenees. As his diagnosis is simply 
translated from that of Schneider, and as my own re- 
marks (loc. cit.) are scarcely sufficient, I give a more 
detailed description :— 
Yellowish green, the head (including face) distinctly more 
yellow. On the vertex is a large obtusely triangular concave 
space, the raised margins of which are often (not always) tinged 
with ferruginous (or reddish brown) ; no spot between the antennz ; 
face frequently (not always) with a bilunate reddish brown trans- 
verse line placed considerably below the insertion of the antenne, 
and there is a small spot (usually darker, almost blackish) on the 
gene; palpi pale, slightly marked with brownish externally. 
Antenne pale, frequently with a reddish line on the basal joint 
externally. Pronotum narrowed in front: in strongly marked 
specimens there is a sublateral ferruginous band on either side, 
not touching the lateral margins, which is continued on the meso- 
notum, and often on the metanotum likewise (but these sublateral 
bands are very variable, and in some examples the only indication
