may be regarded primarily as particular developments of the usual four spots, 

 varying in each individual, and more or less like thick oval spots run together in 

 blotchy marks ; that is to say, each anterior spot is confluent only with the 

 posterior one below it, but does not unite transversely with the others. In one 

 variety the black spots resemble tadpole forms united by the tails ; in another 

 these tails are thickened equal to the spots, and appear as blotchy curves ; and in 

 one variety these blotchy curves are so thick and confluent as to include some of 

 the ordinary side spots, thus completely surrounding two sides of the triangle with 

 a blotchy black border. 



To conclude the description briefly, there is a yellow spot on the spiracular 

 region of each segment excepting the 2nd ; the usual black spots laterally and on 

 the prolegs ; occasionally some fine, short, transverse black streaks on the sides. 

 The head bright ochreous yellow, mottled with red, and spotted with black ; 

 anterior legs reddish-yellow. 



C- verhasci is a larva similar in form, but rather larger and thicker when full 

 grown. The segmental divisions and wrinkles marked with black interrupted 

 streaks; the ground colour whitish, greenish-white, or blueish-green ; a transverse, 

 equally broad band of yellow, extending to below the spiracles on either side, is 

 seen on the middle of each segment. This character is alone sufficient for its 

 identity ; and though this species varies much in colour and size of markings, yet 

 the design remains in all. 



In rudimentary marked varieties, the transverse central yellow band is often 

 interrupted slightly on the centre of the back, and completely, or partially so, 

 at the sides. The upper pair of dorsal black spots entire, and never united to those 

 below. In richly marked individuals, the hinder pair of spots become elongated 

 and approach each other, with tails slightly turning upwards ; in others not so 

 confluent, a small twin pair of dots are seen instead on the yellow band in the 

 centre, midway between the large spots. The yellow transverse bands largely 

 developed on the thoracic segments ; the ordinary spots, dots, and streaks of black 

 on the sides well developed. In some instances the ventral divisions are broadly 

 black, and occasionally the whole surface of the belly black. Perhaps hardly two 

 larvffi could be fovind exactly alike in the minutiee ; but the transverse band of 

 yellow is the conclusive character, strengthened by the additional one of the black 

 anterior dorsal spots never being united to the posterior pair. — Wm. Biickier,

Notes on, and description of, the larva of Colias Edusa. — On the 10th of June 

 last, my friend, Mr. James Terry brought me a fine $ of this species, that he had 

 caught with his hat. It measured 2f in. in expanse of wings, and had evidently 

 been, before hybernation, a splendid insect, though it was then in a worn and 

 ragged condition. 



I placed the butterfly on a plant of Dutch clover {Trifoh'u.m repens), and stood 

 it in a window facing tlie west, and supplied it with a little honey and water ; and 

 two days later I had the satisfaction of seeing ten eggs. The insect was then 

 removed to fresh plants of clover, but the day following being dull and cloudy, no 

 eggs were laid ; and the two succeeding days proving bright and sunny, she re-
