observed in the Eastern Pyrenees, cc. 231 
a very striking local form. The examples from Japan 
do not seem to differ from those from the mainland. I 
have not seen the true C. Walkeri from Asia, but C. perla 
occurs both in Siberia and Japan. 
Chrysopa nana, n. sp. 
Head and thorax whitish (or yellowish) grey above, with a very 
broad black marginal band on either side extending the whole 
length of the thorax (and probably of the abdomen also), some- 
times with a short median fine black line on the anterior portion 
of the pronotum ; face with a black line on either side extending 
along the gene and clypeus; palpi lined with black externally ; 
antenne yellowish grey, sometimes with a blackish line on the 
basal joint externally; pleure and pectus varied with grey and 
blackish. Legs yellowish grey, with short fine black hairs ; a 
black ring at the insertion of the coxe, and another immediately 
before the apex of the femora (more extended on the posterior) ; 
tibiee visibly compressed and somewhat dilated, with a blackish 
spot on the anterior and intermediate slightly before the middle 
externally ; tarsi slightly testaceous ; claws minute, simple. Wings 
long-oval, narrow, subobtuse; neuration with sparse black hairs; 
in the anterior pair the neuration is yellowish (or whitish), costal 
nervules 17—18, black, pale in the centre, the black portion dilated 
into a line at the confluence with the subcosta, and a similar dila- 
tation (with clouding of the membrane) takes place at the axille of 
all the connections of the nervules with the nervures, giving the 
wing a peculiarly irrorated appearance, and there is a large and 
distinct oblong black spot on the third nervule in the space between 
the lower cubitus and the post-costa ; neuration open, most of the 
cellules large and hexagonal; upper portion of third cubital cellule 
oval, the dividing veinlet extending beyond the superposed nervule ; 
pterostigma obsolete, the pterostigmatic space without nervules ; 
three nervules in both gradate series, the outer series close to the 
margin; in the posterior wing the black irrorations are less 
evident. Expanse of wings, 164—18! mm. 
Asia Minor (Adana) and Persia (Shahrud). Four 
examples in my collection. {Also Algeria, see Post- 
script. | 
This striking little species is amongst the smallest 
known in the genus, and is remarkable for the black 
irroration of the otherwise transparent wings. Its 
affinities are probably with C. Genei, which is some- 
times nearly as small, but has broader wings. In the
