228 TUE ENTOMOLOGIST. 



there is a rather broad and very distinctly defined side stripe, 

 of a dingy white colour, extending from the head to the 

 extremity of the anal claspers ; the spiracles are white ; the 

 belly is dingy brown, and the claspers concolorous. It feeds 

 on the leaves of Salix fragilis (crack willow), and will eat 

 lettuce in confinement. At the beginning of August it 

 changes, on the- surface of the ground, to a glabrous brown 

 pupa, with a broad rugose tip to the abdomen, and two 

 incurved spines very distant at the extremity ; each abdo- 

 minal segment has a ring of strong rough spines, somewhat 

 similar to those of the goat moth. I am indebted to Mr. W. 

 Johnson, of Liverpool, for a supply of these interesting larvae.

Life-history of Rhodaria sanguinalis. — The eggs are laid 

 in Julv, among the flowers of the common rosemary (Rosma- 

 rina officinalis), and the young caterpillars, almost as soon as 

 hatched, spin the flowers together, and reside in the domicile 

 thus constructed ; they grow very rapidly, and those collected 

 in September attain their full size in less than three weeks : 

 it is extremely sluggish, and possesses none of that frisky 

 vivacity which is so marked a character of the caterpillars of 

 Pyrausta, which in other respects it seems so nearly to 

 resemble. The head is small and nearly spherical, but 

 slightly depressed ; it is of a yellow colour, with the man- 

 dibles and ocelli brown, and imniedialely behind the latter 

 are two rather large black dots : the body is fusiform, and the 

 2ud segment, which has no corneous plate, is distinguished 

 by a double ring of circular black dots, each of which is sur- 

 mounted by a bristle, as well as all the other black dots in 

 different parts of the body. The ground colour is grayish 

 green tinged with vinous red ; there is a distinct and broad 

 white medio-dorsal stripe extending from the 3rd to the 

 I2lh segment, and a lateral white stripe in the region of the 

 spiracles : the spiracles, which can only be seen with the aid 

 of a powerful lens, are white and surrounded with brown ; the 

 ventral area is of a dingy white and without stripes; both the 

 legs and claspers are concolorous with the body ; the latter 

 are marked at their base with a triple black dot. When full- 

 fed this caterpillar invariably descends from its food-plant, 

 and seeks among dry moss a suitable place to spin its 

 cocoon, which is of an oval form, a paper-like texture, deli-
