A CURIOUS CASE OF PROTECTIVE
COLORATION.
AT Mesilla, N. hf., on Aug. 15, 1897,
sat down to rest while on a collecting excur- sion, and my eyc fell On a clump of the
whitish-green Baileya maltiradiata, with its splendid orange composite flowers. In the middle of the clump was a vanessid pupa, while resting on one of the stems, about to cast its skin, was a sphingid larva. These objects caused me some surprise, as being (so far as J had yet known) foreign to the Baileya, and yet harmonizing perfectly with its peculiar color. The pupa was silver-color with a faint greenish tinge and a golden lustre, with the dorsal prominences and part of the antenna1 coverings ruddy golden. A beautiful and conspicuous object in the hand, it was hardly noticeable on the plant. So also with the larva, which was 35 mtn. long, pale whitish-green, nearly the color of the foliage; caudal horn very pale blue, with dorsal black specks; seven oblique lateral stripes, spiracular openings orange. Taking' the larva home, I found that it would by no means eat Baileya, but it fed greedily on the foliage of Solanitin elaeagaifolwm. It was, in fact, an immature " tomato worm." The pupa, on Aug. 21, gave forth an ordinary example of Pyrameis curdui; the larva must doubtless have wandered from an adjacent Sphaeralcea.
Now are we to suppose that the vanessid
larva came to the Baileyn to pupate, and the sphingid to exuviate, because they realized that they would he protected (2'. e. inconspic- uous) there?

NOTE ON CYDOSIINAE.
IN VIEW of Mr. Cockerell's note on the
larva of Cydosia (Psyche VIII., 130) we have now at least a pnrtial idea, of the young stages of both genera of the Cydosiinae of Smith. Messrs. Hulst and Smith have both remarked on stage I. of Cerathosia (Ent. Amer. V. 48-g), but between the two accounts the essential features seem to have become befogged. The specimens are now before

me.
The egg is noctuid and the larva a true
semi-looping noctuid in primitive first stage, * the single setae stiff, bulbous at tip, per- fectly normal and the subprimaries absent. The larva is excluded from both Arctians and Lithosians by the bulbous setae, us Dr. Packard has shown that no Arctian has glan- dular hairs. "Further the thoriicic tubercles remove it from the Lithosians. Apin the
ihortening of the first two pair of abdominal feet never occurs in the Arctian phylum, but is characteristic of the semilooping Noctuids.
It seems evident that the Cydosii'nae are Noctuids, the character of vein 8 of second- aries being here deceptive, but pariillelcd in some species of Acontia in the Noctuidae, as I have had occasion to notice.

THIS nuturnn Miss Eliot and I found in
Nonq~iitt, Mass., six larvae of Smerinthis asfyltts on Andromeda liyusf&a. We had
never been able to make them eat anything except Vaccinium co~ym6osum and Gaylus-
saciafrondosa. We found also Samia cecro- å´pi on Gdylnssacia frondosu; JSacles iwperi- alis on Primus serotina ; Smerinthzis nyops on birch, willow, and poplar; Datana drefs- dziion llamadis; S. gordinson Andromeda
Ziwtrina; S. excoecatus on Spiraea salici- folia; H. io on Trifolium repels; E. cJloe- rilus on Kalmia a-iqxstzfolia.
We found one larva of Smerinthus
having the spots of a clear mauve color
instead of red or brown; and a larva of H. tJtisbe all red except the dorsal area and first segment.
We found on elder a large sphinx larva of a chocolate brown with obliques and face lines of paler brown, like 5. chersis' except in color. This had been hurt in some way and died.
