PENTHINA. 31 



streaks and mottlings ; three small costal spots are conspicuous between the fascise ; 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. 3 (^, 3 ? . Expanse of 

 wings 21 millims. 



This species differs from P. variegana, Hiibn. (No. 937j Wocke's Cat.); in having no grey 

 shading on the plain apical portion of the wing^ with 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 nimbatana, 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 : head and antennae greyish fuscous. Fore wings more 

 than twice as long as wide— the apical margin scarcely oblique, slightly convex ; apex rounded ;, 

 the costa somewhat arched — brownish fuscous, speckled or blotched with yellowish stone- 

 colour, especially towards the base and on the outer portion of the costa, suffused 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.
