DESCRIPTIONS OF A NEW GENUS AND SOME 
NEW OR INTERESTING SPECIES OF PLANIPENNIA

(With 4 textfigures). 
Haarupiella, gen. nov. 
A recurrent vein at the base of costal area in forewing. 
One crossvein at the base of subcostal area. Radius in 
forewing with 4—5 sectors, the apical one is forked several 
times. Media forks near base of wing, nearly opposite to 
origin of Ist radial sector. 1st crossvein between 1st radial 
sector and M, about one third from base of wing. M, and 
Cu, coalesce for a short distance. Three series of gradate veins 
in the forewing, two series in the hindwing. No cross- 
veins between the apical radial sector and the radius. 
Type: Haarupiella neotropica, sp. nov. 
I dedicate this genus to my friend and colleague, Mr. 
A. C. Jensen-Haarup, who has done so much in order 
to explore the fauna of the Argentine Republic. 
This genus includes, besides the type-species, Haaru- 
piella pallida n. sp., Boriomyia colombiensis Banks, and 
probably also Hemerobius impudicus Gerst. 
It has much likeness to Boriomyia Banks, but is easily 
separated by the presence of three series of gradate veins 
in the forewing and by the coalescence of M, and Cu,.
