latter red on their apical half, yellow-tipped ; the spines are 
set on the definitely margined apex of the scutellum. Abdo- 
men black in ground color, except the apices of segments four 
and five, which are red, ventrally and dorsally ; a consider- 
able amount of black appressed pile on the median three- 
fourths of segments one to three inclusively, a little of this 
extending onto the base of segment four ; segments one to 
three laterally, segment four for the most part, and seg- 
ment five wholly, with straw-yellow pile, that of the venter 
being entirely pale and almost white. Legs mostly blackish 
or reddish-black, the extreme apices of the femora and bases 
of the tibiae, and the middle basitarsi, yellow; pile yellow, 
that of the inner sides of the tarsi golden. Wings yellowish 
hyaline, the veins distinctly yellow; cross-vein r-m very 
short, almost wanting, the discal cell with an appendiculate 
extension in that direction. Stigma distinct, yellow. Length 
5.5 mm. 
Holotype: male, Cordoba, Mexico (Mann).

tic characters of the genus as given by Kertesz in his Mono- 
graph of the Notacantha, as the foregoing description will 
indicate, still I can see no reason for not placing it here.
