OOLIAS HTALE. 17 



before ; the markings much the same, but the dark 

 bristly hairs more conspicuous. They continued to 

 feed in the same way as before until November, and 

 then more and more sparingly until the 18th, when I 

 found the largest was dead ; it was just a quarter of 

 an inch long and very bristly. Another died Decem- 

 ber 12th, and the last on the 28th of December, from 

 mildew on the two hinder segments. (W. B., Note- 

 Book III, 32.) 



On the 27th of July, 1882, I received four eggs of 

 Golias Hyale from Herr Heinrich Disque, of Speyer, 

 they were adhering to the leaflets of Trifolium. Two 

 hatched in the morning of the 1st of August, another 

 at noon that day, and the fourth two hours later. The 

 larvae were offered Medicago lujoulina and Trifolium 

 repens, and chose the latter plant, each taking a posi- 

 tion on the midrib on the upper side of a leaflet, from 

 which they moved to the right or left occasionally to 

 feed, at first by eating away small portions of the 

 cuticle between the veins, and the next day they ate 

 small holes quite through the leaves between the 

 veins ; these larvae were as before described. On the 

 9th I noticed that they had passed their first moult, 

 the day previously at least, perhaps earlier. The head 

 was now coloured like the body, which was of a very 

 deep and dingy green with a faintly darker dorsal 

 stripe, and the spiracular stripe scarcely paler than the 

 ground colour, the entire upper surface being thickly 

 covered with a roughness of minute black bristles ; at 

 this time the length was 4J mm. 



On the 11th one was laid up to moult, and on the 

 14th had moulted during the previous night ; on the 

 15th I observed its head to be rather lighter green 

 than the body, which was very dark and dingy, relieved 

 by a yellowish spiracular line ; the surface of the skin 

 was thickly covered by minute, pale, tubercular, glis- 

 tening specks, each bearing a short, pointed, black 

 bristle. On the 21st all the larvae had been for two 

 or three days laid up to moult, and in the morning of
