PENTHINA.

streaks and mottlings ; three small costal spots arc conspicuous between the fascite ; beyond 
the outer fascia are four or five grey costal spots and a triangular grey shade at the apex, 
which is continued in a broken line along the apical margin ; before this is a greyish-fuscous 
horseshoe-shaped spot, conspicuous upon the plain ground-colour of the wing, sometimes 
connected at its outer edge with the apical margin : a pale fuscous line runs within the base 
of the cilia, the points of which are also touched with fuscous. Hind wings whitish stone- 
grey, with paler cilia. Abdomen and anal tuft slightly ochreous. S ^ ,2 $ . Expanse of 
wings 21 millims. 
This species differs from P. variegana, Hiibn. (No. 937, Wocke's Cat.), in having no grey 
shading on the plain apical portion of the wing, Avith the exception of the one horseshoe-shaped 
spot, also in the larger and more diluted costal spots and more defined central fascia. It lacks 
the strong ochreous tint of P, ochroleucana, Hiibn. (No. 939, Wocke's Cat.), and has paler 
hind wings than that species ; and it may be at once distinguished from P. capreana, Hiibn. 
(P. mcestana, Wocke ; No. 931, Wocke^s Cat.), by the convex (not concave) outer edge of the 
central fascia. In a considerable series from California, obtained in May, June, and July, 
I have found no specimen which could not at once be separated from the numerous nearly 
allied European forms, at least so far as I am acquainted with them. 
Penthina nimhatana, Clem., which is the Penthina contrariana of Walker, differs from 
consanguinana in its smaller size and in the almost unspotted white apical portion of the 
wing, which contains no horseshoe mark. 
Penthina conditana. (Plate LXVII. fig. 7.) 
Palpi depressed, greyish fuscous : liead and antennje greyish fuscous. Fore wings more 
than twice as long as wide — the apical margin scarcely oblique, sliglitly convex ; apex rounded ; 
the costa somewhat arched — brownish fuscous, speckled or blotched with j^^ellowish stone- 
colour, especially towards the base and on the outer portion of the costa, suflused before and 
beyond the middle with a purplish hue, leaving the darker ground-colour in an ill-defined 
rather straight fascia across the middle of the wing, with a slight angulated excrescence about 
the middle of its outer edge, and in a narrow space along the apical margin : the purplish 
suffused band beyond the central fascia is divided into two almost equal parts below the middle 
by a line running parallel to the apical margin. Hind wings dark brown. 2 $ . Expanse 
of wings 12 millims.
