The genus Lomamyia Banks 
Lomamyia Banks, 1904, 4 Proc. Ent. Soc. Wash., vol. 6, 
p. 209. 
Genotype : Hemerobius flavicornis Walk., by monotypy. 
Two species, flavicornis and banksi Carp., are recorded 
from the vicinity of Washington, D. C., and it is possible 
that still others occur here, so the specific identity of the 
larvae described below cannot be determined. 
Immature stages of Lomamyia 
Eggs. — While confined in a glass tube, a female col- 
lected at light on Plummer’s Isl., Md., June 16, 1919, 
laid clustered stalked eggs similar to those of many 
Chrysopidae. There was one cluster of 12 white eggs, 
each about 0.7 mm. long, attached to the end of a thread- 
like stalk 6 mm. long, the terminal end of the stalk being 
more slender than the base. There were several smaller 
and less perfect clusters. After 24 hours the eggs had 
transverse dark bars due to the development of banded 
embryos. Smith (1923, p. 139) has described a single 
infertile unstalked egg laid by a captive female of 
Lomamyia. The unstalked condition may have been ab- 
normal. 
First-stage larva. — General body shape (fig. 2) much 
as in Nallachius, head more elongate; jaws subequal in 
length to palpi and antennae ; 3 pairs of equal legs ; max- 
illa dominant, with scalelike dorsal sculpture (fig. 8), the 
apical tenth specialized and weakly serrate (fig. 7) ; man- 
dible reduced, slender, lateral ; labial palpus and antenna 
3-segmented, second and third segments each with numer- 
ous annulations. Front broadly produced; two lateral 
eye spots ; cervical region and legs well developed ; latero- 
dorsal thoracic sclerites absent or inconspicuous ; 5 thorax 
and abdomen with conspicuous reddish purple transverse 
bands, as shown by stippling (fig. 2). 
4 The genus Lomamyia was first proposed in a list of species ; the formal 
description appeared late the following year in Banks’ revision of the Nearc- 
tic Hemerobiidae.
