and squamation of the head are almost absolutely identical; Szra differ- 
ing from the others in having the head somewhat retracted: the females 
all agree in having the ovipositor extruded. This leaves for generic sepa- 
ration only the shape of the wings, and the modifications of the clypeus. 
The wings in Stadium and Plagiomimicus are alike: in Basilodes the out- 
er margin is less oblique and slightly bulging at the middle: this makes 
the wings more ample, but does not authorize its separation generically: 
Stria has a rudimentary tooth, somewhat like some P/uszas, at the hind 
angle, and the inner margin sinuate. The clypeus in all has a naked 
cup-like depression, which in Basilodes and Stibadium issmooth: in Pla- 
glomimicus the edges are raised and there is a corneous ridge at the inferior 
margin; in S#r7¢z there isa tubercle at this point. I can find no other 
differences, and these for reasons elsewhere given I cannot consider as au- 
thorizing a generic distinction. It is to be remarked that the Pluszad@ to 
which these insects belong, vary considerably in the form of wings and in 
some other characteristics. 
10. This genus I have not seen; it is based on a single species, and 
so far as it is possible to judge from the description, it seems to be iden- 
tical with the foregoing: I have been able to find nothing in the descrip- 
tion which would not as well apply to it, except the expression ‘‘costal 
margin depressed”: this does not seem sufficient to separate them gen- 
erically. : 
ir. Mr Grote says of this genus, that middle and hind tibia are spin- 
ose: I have examined the legs of several specimens, removing them, and 
placing them ona slide for examination under the compound microscope, 
but I have entirely failed to discover any spinulations. I have therefore 
placed it in this section with considerable hesitation as it is of course pos- 
sible that the spines were broken off all the specimens I examined al- 
though they were otherwise perfect. 
12. Very unsatisfactorily separated from Aznaphila Grt., by the pro- 
jecting clypeus and coarser vestiture. The ocelli are also smaller, and less 
remote from the eyes: in all other respects the two seem to agree. 
13. Ln sensu Lederer—Ochria Hb.:; this genus differs from Hydroecia 
only by the conic frontal tubercle: this is not sufficient to separate it gen- 
erically, but as I do not know Gordyna in nature, I prefer to leave mat- 
ters as they are. It is to be noted however that some Hydroeza are aber- 
rant, and more like the typical European Gorfima while from what Mr. 
Grote says of Gortyna (Ochria) sanzalite, it is not to be separated from 
Fiydroecia except by the frontal tuberele, and does not seem nearly rela- 
ted to the European species.
