336 THE ENTOMOLOGIST. 



The following notes on larvae I took from living specimens in 

 my own possession : — 



Aurelia. — Larvae found at Sion, April 25th, in the middle of 

 plantain-leaves, only one being found beneath. General appear- 

 ance grey with white spines, apparently set on yellow-brown 

 lines ; rather closely resembling fallen alder-catkins. Seen 

 through lens, the ground colour is shown to be black, thickly 

 studded with white dots in transverse lines. There are eleven 

 transverse rows of short spines or papillae, the five central 

 yellowish brown at the base, all being very white at the tips, the 

 two lowest on each side white throughout. The five central 

 rows have many black setae pointing upwards, the sub-spiracular 

 (which is placed on a white line) has the black setae spreading 

 out laterally. The double ventral row is much smaller, with few 

 hairs. The arrangement of the spines is, except as described 

 above, the same as in Buckler's description of the larva of 

 athalia. Spiracles black surrounded by white. Head shiny, 

 black with white dots. True legs black and shiny. Prolegs white, 

 with slight greenish tinge. Head and prothorax retractile. 



First went up April 27th ; found as pupa (fallen) April 30th. 



Parthenie. — Larvae found at Charpigny, April 29th, on plan- 

 tain-leaves, not disposed like aurelia to eat out the middle of the 

 plant, but more frequently found on the edges or under the leaves. 

 General appearance darker, brighter, and rather larger, also 

 with browner spines than the aurelia larvae from Sion. Spines 

 arranged as in athalia, with the exceptions mentioned above. 

 The white lateral line is less visible than in aurelia, and is 

 succeeded beneath by a purplish-chocolate band, more or less 

 broken, which is much less visible in aurelia. The larva is not 

 unlike the last year's seeds of the plantain. 



First went up April 29th, one on May 1st, two more on the 

 2nd, &c. 



Dictynna. — Larva found at Caux, June 3rd. General appear- 

 ance grey, with yellow-brown spines. Through lens, black 

 ground with much white in spots and streaks. Spines yellow- 

 brown to tip, which is just touched with white. Prolegs light 

 semi-transparent greenish, hooks black. Legs black. Head 

 black, with only a few white spots on the top, and a white 

 streak above the mouth. Spines, as usual, in eleven rows. Only 

 double ventral and slight indication of central* rows on pro- 

 thorax ; dorsal and sub-spiracular rows absent on meso- and 

 metathorax, and the upper ventral truncated, especially on the 

 latter. The long pair on the tenth abdominal appear to be the 

 upper ventral. Otherwise as in athalia. The ventral pairs, 

 especially the lower, much whiter than the other spines. 



Full-fed larva of var. herisalensis, received from WuUschlegel, 



* This does not include, I think, anything to represent the dorsal row.
