The Genus Notiobiella

CONCERNING THE GENUS NOTIOBIELLA 
(NEUROPT.-HEMEROBIIDiE) 
By Nathan Banks 
In recent years several genera have been made for forms 
agreeing with Notiobiella in having but one series of grad- 
ate veins in the fore wings. 
Buxtonia Petersen 1928 (Insects Samoa) was based on 
males with enlarged veinlets in the stigmal area. 
Vaja, Navas 1925, from Java and Ganchetus, Navas 1929 
(Insecta Nova XIII) from Kamerun were based on an elon- 
gate pronotum, together with certain slight venational 
points. 
Having a species of Notiobiella from the Malay Peninsula 
which has a long pronotum I have gone over the material 
in this genus available to me. 
Notiobiella was published in 1909 with live species, four 
from Australia and one from the Fiji Islands. Shortly 
afterward Needham published a genus, Annandalia from 
India based on one species — - curta . In my original descrip- 
tion of Notiobiella I mention N. unita as type, so that the 
genus must be interpreted in this sense. The length of the 
pronotum varies from much broader than long to almost 
as long, fully as long, and plainly longer, and one specimen 
with a pronotum nearly twice as long as broad. This point 
therefore should not be used as a generic character. The 
size of the veinlets in the stigmal area used by Petersen for 
his Buxtonia is only developed in the males of certain spe- 
cies; his statement that my N. stigmatica would go in his 
new genus is correct; but I suspect that N. stigmatica is 
the male of N. unita, the type of the genus. 
Navas mentions that in Ganchetus there is in the hind- 
wing a “venulis externis.” I have a species from Mada- 
gascar that has two such veins in one hind wing, and only
