broad, spatulate with sclerotized teeth on lateral margins 
of tip (Fig. 1, B). Dorsal inner processes small but 
longer than ventral inner processes. Ninth sternite small 
with a shallow excavation in middle. Apicolateral pro- 
cesses small and blunt. 
Length: 1.4 mm.; wing 1.0 mm. x 0.5 mm.; female slightly 
larger. 
Type Data: Holotype; male, Storrs, Conn., May 18, 1953 
(F. B. Lewis) ; USNM type No. 62699, deposited in U.S. 
National Museum. Paratypes; male, Storrs, Conn., June 
15, 1953 (F. B. Lewis) ; two females, Storrs, Conn., June 
14, 1954 (F. B. Lewis) ; deposited in USNM, University 
of Connecticut, and author’s collections. 
Comparative Notes: A small blackish species having a 
shiny black thorax and a dull black abdomen with brown- 
ish blue pruinescence. The wings are whitish. This species 
keys out to pruinosa in Wirth’s (1952) 2 key to the Cali- 
fornia species. Serrata resembles pruinosa Wirth closely 
but differs in the bluish cast, larger size, and unequal 
claws. The most outstanding difference is between the 
aedeagi of the two species. The toothed edges of serrata' s 
aedeagus is the best distinguishing character as it sep- 
arated the species from all others in the genus known to 
the author. The bluish cast will separate either sex from 
all known New England species.
