230 Mr. McLachlan on species of Chrysopa 
mostly black, those below the sector interrupted with pale or 
wholly pale in their lower half, and those between the two rows of 
gradate nervules wholly pale. In the posterior wings the neura- 
tion is for the most part pale, excepting the costal and gradate 
nervules, and those (in part) between the radius and sector. 
In 1867 two examples from Mehadia in Hungary 
(J. Mann) were sent to me by Dr. Brauer under the 
name here retained, and this name has found its way 
into catalogues and lists; but the species is now de- 
scribed for the first time. At Vernet-les-Bains it was 
very common, and easy to recognise on the wing on 
account of its peculiar green, and in this respect easy 
to distinguish from C. perla (which occurred with it, but 
more sparingly), the latter being very conspicuous on 
the wing by its blue-green ‘‘ shimmer.” 
The two species (Walkeri and perla) are no doubt 
closely allied, but very distinct; the black markings on 
the head, &c., are less pronounced in Walkeri, and in 
it the A isalways open posteriorly, whereas in perla it is 
closed. In this respect Walkeri somewhat resembles the 
North American upsilon, A. Fitch, which is a smaller 
species, and there is analogy with the European dorsalis, 
Burm. 
Chrysopa intima, Ni. sp. 
Closely allied to C. Walkeri. Differs principally as 
follows :— 
The spots on the top of the head touching each eye are never 
connected by a line along the posterior margin of the head; the 
two spots on the middle of the vertex near the posterior margin 
are neither connected nor contiguous, but always distant, so that 
the distance between them is not much less than that between 
each of them and the spot touching the eye; the two branches of 
the A are rather more divergent. The palpi are paler. On the 
pronotum, instead of the broad black margins, are three black spots 
on either side (the lowest sometimes indistinct on account of 
retraction), and the markings on the meso- and meta-nota resolve 
themselves into distinct spots. The pectus and pleure entirely 
without markings, save a spot in the centre of the prosternum.

(Grdser). Japan (Lewis, Pryer). 
Formerly I used to consider the Asiatic examples above 
noticed were C. Walkeri, but it seems to me that the 
characters here given indicate a species, or at any rate
