analysis of it as a" whole. Under the heading Ccecilius (^Pteroclelci) pedi- 
cularius, L., the author states that Psocus salicis, Hag., and geologuSy 
Walsh (and perhaps pusillus, Harris), are synonyms ; the species is rede- 
scribed ; Hiley has bred it from leaf-galls, but Linne had long ago 
described a species from galls as a Tenthredo^ and also as Cynips salicis 
strohili. Many Hsocma have the claws toothed; m C. pedicularius 
others there is a very curious structure at the base of the claw in the 
shape of a hose, which if dilated forms a long funnel. Elipsocus is a 
natural geuus, and Mesopsocus^ Kolbe, does not present sufficient differ- 
ences for generic separation, more especially as E. laticeps, Kolbe, is 
perhaps not distinct from M. unipunctatus ; Ps. signatus, Hag., is not 
distinct ; details for the short-winged forms (doubted by Kolbe) are 
given. Under Psocus venosus, Burm., is a very detailed account in 
different sections : at the extreme base of the wings there is a chitinous 
space having the appearance of a sieve, but in each of the apparent holes 
is a small bristle, the whole neuration (with slight exception) forming 
a double net, not only of veins but also of tracheae ; the “pterostigma 
hook forms the dark spot at the base of the pterostigma, its structure is 
fully described ; the “ lock ” of the fore -wings, by which the wings are 
united during flight, is fully described ; the mouth parts differ apparently 
from those of all other insects, inasmuch as the inner lobe of the 
maxillae slides in the outer as in a sheath, and was long ago indicated by 
Latreille. Amphigeronlia, Kolbe, cannot stand on the characters assigned 
to it. Ps. variegatus, Latr., is also American ; Ps. moestus, Hag., is allied, 
but perhaps distinct, and is redescribed; P. lichenotus, Walsh, is also 
allied and is likewise redescribed ; these are the only North American 
species that can fall into AmpJiigerontia.

Observations on the occurrence of the insect in a palm-house at 
Cologne, on A spidistria elatior, a Japanese plant; hence the author 
thinks Japan may be its native country. It was originally found in a 
palm-house in Belgium.

In Beitriige Kenntniss Buss. Beich. (2) i. p. 89 [1879], Koppen refers 
to a previous observation by Motschoulsky to the effect that a species of 
Psocus {Ps. cer calls, Motsch., without description) w’^as destructive to 
rye in Bussia, and doubts the accuracy of the observation. [The insect 
was probably Cvccilius pedicularius, L., and its food the mildew on the 
rye. — B ec.]
