228 Mr. McLachlan on species of Chrysopa 
many species of Chrysopa; such is my experience. 
Next to Ash comes Lime (Z%lia). The inference is that 
such trees furnish the Aphides, or Coccids, on which the 
larvee feed; but many species frequent any kind of 
decidvous tree indiscriminately, varying only in degree 
of abundance. A few affect conifers (and especially 
Abies excelsa) almost exclusively, their prey evidently 
being attached to the same trees. And I am convinced 
that a small number (e. g., C. phyllochroma) are probably 
attached to herbaceous plants. These remarks of course 
apply to European forms. The foregoing notes on 
habits are incidental only, and not specially connected 
with the Kastern Pyrenees. 
The few descriptions of new or little-known forms, 
here given, partly concern the species of the Kastern 
Pyrenees, and are partly the outcome of a general 
review of my Palearctic collection. To the small band 
of entomologists who have attended critically to this 
genus it is needless to state that if the difficulties con- 
nected with the determination of isolated specimens be 
creat, they often increase in direct proportion to the 
number of specimens. 
List oF SPECIES CAPTURED AT VERNET-LES-Batns, 
AND Vicinity (PYRENEES ORIENTALES). 
Chrysopa perla, L.—Tolerably common. 
C. Walkeri (Brauer), McLach., n.sp., see p. 229.— 
Very common. 
C. septempunctata, Wesm.—About ten examples ex- 
hibiting no variation. 
C. aspersa, Wesm.—Very abundant, and very variable, 
as elsewhere. ‘There can be little doubt that this should 
take the name of prasina, Burm., but as there is just a 
shade of suspicion that more than one species is included 
in the varying forms of “‘aspersa,”’ I think it better to 
leave the matter as given in my article in Ent. Month. 
Mag., xxill., pp. 38—36. 
C. Picteti, McLach. (=thoracica, Ed. Pict., nom. preoce., 
cf. Ent. Month. Mag., xvii., p. 63).—One somewhat 
doubtful example. 
C. lineolata, McLach. (= clathrata, Ed. Pict., nec 
Schnd.), see p. 282.—Hight examples. 
C. flavifrons, Brauer.—Most abundant and very vari-
