of hyaline wings, a rather slender body and the posterior legs fitted for 
walking. The forelegs have the tibia bent back upon the femur as in the 
Mantidce. 
Nothing is known of the life his¬ 
tory of our species ; Brauer records 
that one European species lays stal¬ 
ked eggs, as do the H enter obiidce, and 
that the larva finds its way to the 
egg-mass of a spider and there feeds 
Fig. 74.— Mantispa. x 2. on the eggs and young spiders ; it 
pupates in the web that contained 
the spider’s eggs, and the pupa, when ready to transform, pierces its 
cocoon and the spider’s web, the imago then emerging. Glenurus pupil- 
latus Navas., Mantispa rugicollis Navas., and M. Hamiltonella , Westw. 
have been described from India, as also has M. nodosa, Westw. which 
occurs in Assam and is figured by Westwood (Cab. Or. Entom., pi. XXIV, 
fig. 7). 
Hemerobiince .—The antenme moniliform. 
This sub-family includes two types of insects, of which some of each 
are known in India. The Sisyrini live as larvae in freshwater sponges, 
and Annandale has recorded one as having 
been found in this situation in Calcutta. The 
student should consult Sharp’s volume, where 
there is a good figure of the larva. Osmylus 
perspicillaris. Gerst., 0. langii Mach, 0. 
lineaticollis Mach, and Dilar Hornei Mack, are 
Indian species. The Hemerobiini are represen¬ 
ted by one delicate brownish insect whose larva 
feeds on the cotton aphis. The life history 
differs only in detail from that of Chrysopa in 
the next sub-family ; the eggs are laid on stalks ; 
the larva is naked and feeds voraciously on 
aphides, sucking them out with its long 
mandibles. In this species pupation takes 
place under a very delicate web on a leaf. 
This insect is less common than its ally, the
