pine and deodar in Simla. An account of what is known of the life history 
will be found in Sharp’s insects. They will be confused with Aleur- 
odidce if not carefully examined ; the mouthparts are well developed 
with prominent palpi ; the wing venation is comparatively complex and 
the tarsi five-jointed. The wings are white, the body red in one species 
Enderlein has listed the family (Genera Insectorum, 1908); no 
Indian species are recorded. He states that the larvae, after feeding 
on Coccids, spin a web by means of anal spinnerets and rest under 
it till spring, when they pupate and emerge. 
Collecting .—Special methods of collecting are not required in this 
family, but great care must be taken to preserve the specimens from 
damp as in all groups of Neuroptera. Myrmeleonides and Ascalaphides 
are on the wing once a year and come to lights. Nemopterids come out 
in houses at dusk and dance; the remainder must be sought for in their 
haunts. Any killing bottle is good, so long as it is quite dry. Good series 
of all species are required, and in this group there is very much biological 
work to be done before we can fully estimate the value of this family. 
Trichoptera.— CW& flies. 
Wings hairy, the hind wing larger, with a folded anal area. Coxce long 
and contiguous. Antennw long, tarsi five-jointed. 
The family can be distinguished by the above characters with some 
doubt, since the hairiness of the wings is not always noticeable. They
