390 HETEROCERA. 
It is most probable that WV. iniqgua will prove to be the female of NV. textilis, Guén. ; 
all the specimens of the former known to us are of this sex.

Our Mexican specimen very closely resembles Felder and Rogenhofer’s figure of 
Phurys coactilis. This species varies considerably in colour, and in the size of the 
black spot near the base of the primaries, it being almost obsolete in some specimens. 
ISOGONA. 
Isogona, Guénée, Sp. gén. des Lép. vii. p. 8322 (1852) ; Walker, Cat. xiv. p. 1515. 
Guénée and Walker include two species in this genus, one from North America and 
the other from Brazil. We are now enabled to trace the southern species northwards 
to Mexico, and to add a new one from our region.

This is a common species throughout our region. Mr. Butler states (Trans. Ent. 
Soc. Lond. 1879, p. 55) that Massava scissa, Walk.=Tsogona continua, Guén. 
2. Isogona eolia, sp.n. (Tab. XX XIII. fig. 1.) 
Primaries pale brownish-fawn-colour, crossed near the outer margin from the costal to the inner margin by a 
wide dark brown band, the latter edged with a pale line on the outer side, and with three indistinct 
waved lines crossing the wing between the base and the dark brown band; secondaries dull brownish- 
fawn-colour, darkest round the outer margin ; the fringe of both the primaries and the secondaries pale 
greyish-brown; the underside of both wings pale dove-colour, crossed beyond the middle by narrow in- 
distinct darker brown lines: head, thorax, and abdomen greyish-brown, the anal tuft yellowish-brown, 
the antenne and palpi pale brown, the legs brown. Expanse 14 inch.
