Within is an elastic bar, which is rolled up in a condition of re- 
pose; when extended it brings the lobule into.contact with the 
surface on which the insect is standing. There are no well- 
developed gland-cells. After descriptions of other modes of fixa- 
tion, the author gives the following table

The legs may, further, have a sexual function as attaching or 
holding organs; or, as in Mantis religiosa, Nepa cinerea, etc., they 
may be of use in seizing prey; and, finally they may be used as 
cleansing organs. The legs in ants may be seen to be pectinate, 
an admirable arrangement for forms that live in dust and earth; | 
they are often especially adapted for cleansing the proboscis and 
for other functions, for an account of which we must refer to the 
paper itself. 
Entomo.ocicaL Notes.—Dr. Brauer, says Psyche (Aug., Sept.) 
has noticed the transformations of a fly (Hirmoneura obscura) 
whose larva lives on that of the grub pee pupa of the June beetle, 
Rhizotrogus solstitialis. Mr. O. Lugger, according to Science 
Record has discovered a strange hymenopterous parasite infest- 
ing the larva of Tiphia, a black sand-wasp. The Tiphia lays its 
eggs in the larva of our June beetle (Lachnosterna fusca); the 
larva of Tiphia when nearly mature eats the white grub and then 
spins for itself a beautiful silken cocoon. This larva in turn is 
often infested by the larva of Rhzpiphorus pectinatus or R. limbatus, 
the eggs of which have become fastened to the Tiphia, and in this 
way reach the Tiphia cocoon. Mr. Lugger has also found in the 
same cocoons small hymenopterous parasites. — Interesting cases 
of lack of symmetry among insects are described in Psyche 
by O.P. Krancher. Mr. P. Cameron states in the Entomologist s 
Monthly Magazine for October that since the publication of 
the first volume of his Monograph of British Phytophagous
