PHYCITINAE 
Acrosasis Zeller. 
In the Proc. Ent. Soc. Wash. X, 41 Dr. Dyar has revised this 
genus, giving a key to the species based on the ¢ sexual characters. 
Unfortunately for the general entomological public, who are apt to 
regard work from Washington as authoritative, Dr. Dyar has totally 
misidentified most of the older species, the types of which were not 
in America; it is a pity that an entomologist of Dr. Dyar’s standing, 
with the ability and the opportunity to do such excellent work, has 
not ere this taken the trouble to obtain correctly determined material, 
but has relied on old existing determinations in the museum. In con- 
sequence a large portion of his work, as in the paper under discussion, 
is full of flaws, and only serves to make the existing confusion in 
nomenclature worse confounded; it is such work which is responsible 
for the constant shifting of names and the corresponding disgust on 
the part of economic workers with the whole question of nomenclature. 
We offer the following notes based on the study of the type materia! 
and would recommend to Dr. Dyar a similar method of procedure 
before he treats us to any further Keys to Species. 
ANGUSELLA Grt. (syn. eliella Dyar) 
In his original description of this species (N. Am. Ent. I, 51) 
Grote had two species confused ; these he separates later, (Pap. I, 14) 
limiting angusella to the species with single black costal streak on 
underside of secondaries, a limitation confirmed by the ¢ type in the 
British Museum. According to Dr. Dyar’s table angusella has two 
streaks on secondaries, which is wrong. A correct use of the table 
would lead us to eliella Dyar which is indeed synonymous with the 
true angusella Grt.; we have several specimens of eliella ex Coll. 
Merrick received from Mr. Ely himself and collected in the type 
locality. 
DEMOTELLA Grt. 
The type ¢ has a distinct black costal streak on under side of 
primaries, longer than in angusella and two streaks on secondaries, the 
costal one narrow at base and swelling to an oval patch at middle of 
wing, the median streak rather diffuse; this is probably Dyar’s angu-
