Italy, Sicily, Dalmatia, &c. Taking the colour generally, as in dry 
examples, clathrata may be distinctly termed a dark insect, and cla- 
thrata , Piet., a pale one. The true clathrata has the sides of the thorax 
broadly margined with dark fuscous, the costal nervules entirely 
blackish or nearly so, and the other nervules with only a short pale 
median space. In Pictet’s species the colour of the markings on the 
body is reddish-brown, the bands on thorax are not lateral, but sub- 
lateral, in the form of lines, leaving the margins pale ; the nervules 
are much less marked with black, and in all cases (excepting the gradate 
series) only as a point at either end : the whole form is less robust ; 
the markings on the face also differ, none of Pictet’s examples show 
the spot between the antennae of which he speaks (and it is not fre- 
quent in the true clathrata ) ; the basal joint of the antennae has often 
a brown line externally. I have seen Pictet’s insect from no other 
quarter, and propose for it the name lineolata. 
Chrysopa yranadensis, Ed. Piet., p. 69, pi. vi, figs. 5 — 8. — A small 
species described from a single example. Apparently quite distinct. 
Possibly allied to lineolata. 
Chrysopa riparia , Ed. Piet., p. 69, pi. vii, figs. 9 — 12. — Two ex- 
amples are before me, in very bad condition. 
Chrysopa monticola, Ed. Piet., p. 70, pi. vii, figs. 1 — 4. — From the 
French Pyrenees. Allied to riparia , but apparently distinct. The 
“ tache semi-lunaire rouge devant les yeux ” is not apparent in the only 
type with a head. It is probable that nigro -punctata , Meyeri , riparia , 
and monticola belong to the same group as flavifrons (Brauer), in which 
there is a black or brown dot at the extreme base of the costa in the 
anterior-wings, but no spot between the antenna 1 . 
Chrysopa venosa (Eambur), Ed. Piet., p. 72. — One of the few 
species with simple claws. Otherwise this species has the form and 
facies of Ch. perla , and is allied thereto. 
Chrysopa italica (Rossi), Ed. Pictet, p. 72. — This, as is well known, 
belongs to my genus Nothochrysa. It was not taken by Pictet, and I 
mention it only in order to call attention to a curious structure seen 
in an example once forwarded by Dr. Bolivar, of Madrid. In the 
abdomen of one sex (probably the <^) there are concealed two long 
curved spines in a pouch between two of the apical ventral segments. 
I have seen them in no other example, owing to the pouch being closed, 
and neglected to take an exact description when the individual was 
before me.
