14 February, 1896. The 19th meeting
was held at 156Brattle St., Mr. S. H. Scudder in the chair.
Prof. C. M. Weed read his presidential
address for 1895 on the Hibernation of
Aphides.
In continuation of his remarks at the last meeting, Mr. A. G. Meyei- said the cells from the scales of Lepidoptera were modified hypo- dermic cells and homologous with hairs.
The pigment of the scales is derived from the blood, a haemolymph, of the chrysalis, which fills the scales while the pigment is forming. The haemolymph is an albumin-
011s fluid containing a strong acid; its min- eral bases contain a large amount of iron and also potassium and sodium in small
quantities. The following facts confirm the statement that the pigments of the mature wings arc derived from the blood of the
chrysalis. The red band on the hind wing of Sawin -cecropia becomes yellow by the addition of hydrochloric or nitric acid, but its red color is restored by ammonia The blood of the pupa of that species when treated with warm nitric acid becomes yellow, and is changed to ormge-red by ammonia; the
application of hydrochloric or nitric acid again turns ityellow, the color being restored by ammonia, exactly as is the case with the red color of the mature wing. Also, if the blood of Callosnmia promethea is treated with hydrochloric acid find a minute crystal of chloratc of potash sit a gentle heat, it becomes purple, but is blackened to a drab color by nitric acid. The purple spots near the outer edge of the hind wingof the female moth are similarly bleached to a drab color upon application of nitric acid. Most of the colors of the wings are probably derived from the blood of thc chrysalis by processes of oxydation.
In answer to questions, Mr. Meyer stated that it was in the last stages of the pupa that the pigment was developed; and that colors
