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 cui'ves 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 bi'iefly, 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- verbasci is a larva similar in fonn, 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 blneish-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 
larvae could be found exactly alike in the minutiae ; 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. Buckiee,

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 2| 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 [Trifolium repens), and stood 
it in a window facing the 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 tlie two succeeding days proving bright and sunny, she re-
