NOTES ON THE SYNONYMY OF NOCTUID MOTHS. 11 
The genus Pteretholix is identical with Berresa, Walk. (Cat. 
Lep. Het. xvi. p. 214, 1858), and is allied to Ilattia. 
PERIGHA, Guen. 
Perigea conducta. 
Caradrina consocia, Walker, Lep. Het. x. p. 299, n. 40 (1856). 
Hab. —? Coll. B. M. 
This is another synonym of this much described species. 
The following genera belong to the later group, in which the 
radial vein of the secondaries is emitted near to or from the same 
point as the third medial branch. 
Grote says (Check List, p. 37), in explanation of his use of 
the term Hustrotia in place of Erastria, ‘I cannot use Hrastria 
for this genus, because Hubner uses that term before Treitschke 
for a genus of Geometride. If used only in the ‘ Tentamen,’ the 
publication of which by Hubner is improbable, I should ignore 
it. In the ‘ Verzeichniss’ the term is only used in the plural 
(p. 299) to indicate a Stirps; moreover, I believe that Treitschke 
has priority over this use of the name.” 
ERASTRITDAL. 
Nipista, Walk. 
Nipista tigris. 
Diastema tigris, Guenée, Noct. i. p. 1127. 
Nipista lineata, Walker, Cat. Lep. Het. xu. p. 800, n. 1 (1857). 
Venezuela and Sta. Martha. Coll. B. M. 
This has little in common with Diastema virgo ; it is, in fact, 
much nearer to the Leptosia concinnimacula of Guenée, which I 
would suggest should be, for the present at any rate, associated 
with it, as it has not the palpi of the Kuropean insects placed 
with it by its describer, nor can I see my way clear to admitting 
it into Hrastria. 
COSMOPHILIDA. 
Gonitis, Guen. 
Gonitis editrix. 
Gonitis editrix, Guenée, Noct. ii. p. 404, pl. 11, fig. 5.

South America, West Indies. Coll. B. M. 
Gonitis sabulifera.
