Italy, Sicily, Dalmatia, &c. Taking the colour generally, as in dry 

 examples, clathrata may be distinctly termed a dart insect, and cla- 

 thrata, Pict., 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 antennas has often 

 a brown line externally. I have seen Pictet's insect from no other 

 quarter, and propose for it the name lineolata. 



Chrysopa granadensis, Ed. Pict., 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. Pict., p. 69, pi. vii, figs. 9 — 12. — Two ex- 

 amples are before me, in very bad condition. 



Chrysopa monticola, Ed. Pict., p. 70, pi. vii, figs. 1 — 4. — From the 

 Erench 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 antennae. 



Chrysopa venosa (Rambur), Ed. Pict., 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.
