larger extend over the commencement of the fissure, extending to the 

 fringes on the inner margin ; on the lower lobe are two other white 

 spots. The hind-wings are somewhat lighter brown, their fringes 

 almost grey ; they are divided into three plumules by two fissures, the 

 upper cleft reaching only half way up the wing. On the undersides, 

 there are several white spots on the blackish-brown ground colour 

 and on the fringes. The moth was taken in the month of June in the 

 bushes on the Anninger near Modling " (I.e.). Stainton's diagnosis 

 of this species is as follows: — "9"' — g%". Fore-wings dark brown, 

 with the costa and fringes spotted with white ; hind-wings dark 

 brown, with a white blotch in the fringes of the second feather. VII." 

 (" Manual," II., p. 444). The following description was made by 

 Mr. South from a foreign specimen: — "Imago — Expanse, 10 — n| 

 lines. Fore-wings black, sprinkled with ochreous-brown scales, 

 especially on the disc, which seems in consequence to be of a brownish- 

 black coloration ; a small white dot on the costa above the digital 

 juncture, from which an ochreous line, sharply angulated at the 

 juncture, runs to the inner margin ; fringes black, ornamented with 

 white at the tip of the outer and the angle of the inner digit ; there 

 are also some white scales edging the digital juncture, and a patch of 

 white scales on the fringes of the inner margin at the termination of 

 the ochreous transverse line. Hind-wings blackish-brown ; fringes 

 of second feather grey from the base to the middle, and white near 

 the tip ; there are also some white scales at the junction of the first 

 and second feathers. Head and thorax the colour of the fore-wings. 

 Abdomen brown, ornamented with lateral white spots. Legs brown, 

 the tibiae with one, and the tarsi with four white marks or rings " 

 (" Entomologist," Vol. XXII., p. 36). 



Larva — Of the larva of this species Dr. Jordan writes: — "In June 

 1856, I received through the kindness of Mr. Stainton (who had them 

 from Professor Zeller of Zurich), two larvae of Pterophovus brachy- 

 dactylus ; they were found on Prenanthes purpurea, but whilst in my 

 possession they ate Lactuca muralis freely, feeding on the upper surface 

 of the leaf, and living on it without any attempt at concealment. The 

 larvae were narrowly fusiform in shape, not flattened from above 

 downwards, and with sixteen feet, the two segments which followed 

 the three pairs of true legs having, however, prominences beneath. 

 The head was yellowish-brown ; the body green, with the dorsal line 

 of a darker green colour ; the sub-dorsal line was also dark green, but 

 so wavy as almost to present the appearance of separate spots upon 

 each segment ; the spiracles were black. There were two rows of lateral 

 tubercles, each of which had a few dusky grey hairs springing from it. 

 Neither of the larvae were reared ; when apparently full-fed they 

 became stationary, without forming any silken fastening, and in a few
