Lewis — Ceratopogonidae 
49 
Comparative Notes: A blackish species with shiny black 
thorax and legs brownish with black knees. The speci- 
mens were taken from a small brook-fed bay on a large 
lake. The water was still and algae-choked. This species 
resembles J ohannsenomyia syblae Wirth from California, 
but differs in the details of the male genitalia. The 
genitalia easily separate this species from any known 
New England species. This species is named for Dr. 
Howard W. Smith in appreciation of his continued advice 
and help during the author’s study. 
The Identity of Lordomyrma rugosa Clark. — Through 
the courtesy of Curator Elisabetha Bajari of the Hungarian 
National Museum, I have been able to examine the type 
of Dacryon christae Forel (1907, Ann. Mus. Nat Hungar., 
5: 16, worker: type loc., Botany Bay, Sydney, New South 
Wales) and to compare it with nidotypes and topotypes 
of Lordomyra rugosa Clark (1934, Mem. Nat Mus. Vic- 
toria, Melbourne 8 : 38, pi. Ill, figs. 3, 4, worker, female : 
type loc., Ferntree Gully, Victoria) and with a worker 
and female from Como, New South Wales (J. Freeland). 
All of these samples appear to represent a single species. 
The type is a rather small example, with a relatively 
slightly narrower head (head L, including clypeus, 0.92 
mm., head width without eyes 0.82 mm.), but in other 
ways agrees perfectly with the rugosa types. Lordomyrma 
rugosa must therefore be considered as a new synonym 
of Dacryon christae. This species varies appreciably in 
depth of color, length of propodeal and petiolar teeth, and 
coarseness of sculpture. At Ferntree Gully, Victoria, where 
I collected the species, it nested in small colonies (40-50 
workers, one queen) under stones in grassy-floored sclero- 
phyll forest of the intermediate moisture type. The adults 
feign death when disturbed. — W. L. Brown, Jr., Museum
