species to the genus — namely, Aleyrodes hergii Signoret. A com- 

 parison of the type of Aleyrodes sacchari Maskell with hergii leads us 

 to beheve that Maskell's species is the same as hergii Signoret. Below 

 are given the characteristics of NeomasJcelUa and a key to the two 

 known species of the genus, followed by a description of hergii. A 

 revised description of comata was given in Technical Series 27, part 

 1, of the Bureau of Entomology, United States Department of Agri- 

 culture, on page 92. 



Pujpa case. — Elliptic, with reflexed edges; margin with row of 

 prominent spines. PapUlae and dorsal pores absent. Vasiform 

 orifice on a tubercle-Uke elevation, transverse, eUiptical; operculum 

 short and broad, about haK fiUing the orifice; hngula similar in 

 shape and visible caudad of the operculum. Adult males much 

 smaller than the females; forewing with only radial sector present. 

 Females with radial sector and traces of the cubitus ; vertex depressed 

 mesad and with the lateral margins elevated. Antennae short, 

 thick, and hairy, composed of seven segments, of which the third is 

 the longest; second segment spherical; claspers of male short, thick, 

 and hairy. 



Type. — Neomaslcellia comata (MaskeU). 



KEY TO SPECIES OF NEOMASKELLIA. 



1. Pupa case with 12 pairs of spines arising from submarginal area, the cephalic two 



pairs short and hair-like. Forewing of adult with foiu- faint brownish patches 

 comata. 



2. Pupa case with 16 pairs of spines arising from submarginal area, the cephalic two 



pairs equally developed with the others. Forewing of adidt mottled and dotted 

 with dark brown bergii.

We have specimens of this species from Java, received from Dr. 

 L. Zehntner, February 1, 1897 (host not stated), and also specimens 

 collected by Mr. George Compere at Manila, Philippine Islands, on a 

 wild grass. 



Egg (fig. 1). — Length 0.272 mm.; form oval, with the stalk attached 

 a short distance from the base and about half as long as the egg 

 itself. We are unable to make out any surface sculpturing in the 

 specimens at hand. 



Pupa case (fig. 2).— Length from 0.72 to 0.8 mm.; width from 

 0.432 to 5.52 mm.; shape elhptic, rather strongly arched; abdom-
