affinities with Nallachius and Lomamyia that appear 
stronger than any shown by the rapliidiids. 8 Trichosors 
or marginal dots and dashes of the wings, discussed by 
Killington (1936, p. 34) and Comstock (1918, p. 167), 
occur in Dilaridae, Berothidae, and some Mantispidae, as 
well as certain other families, but not in the Raphidiidae 
that I have examinel. The swollen body and reduced 
legs of mature Lomamyia larvae suggest an approach to 
the parasitic habit, with even more swollen body, of 
Mantispidae. The claws and empodinm, as well as cer- 
tain other structures discussed by Withycombe (1925), 
of first-stage larvae of Mantispidae are very similar to 
those of Lomamyia. I have examined larvae of an un- 
identified mantispid found by J. C. Bridwell in 1938 in 
alcohol in which spiders had been collected. In addition 
to the Nymphidae and Myiodactylidae, the Berothidae, 
Mantispidae, and Chrysopidae are known to lay stalked 
eggs. While raptorial front legs give the Mantispidae 
a quite different superficial appearance from either 
Dilaridae or Berothidae, they are regarded by Withycombe 
(1925, p. 329) as a specialization rather than as evidence 
of fundamental lack of relationship.
