Extract

Pupal Term of Arctia nais.

♀ found June 16, 1875, laying eggs in a depression in ground recently dug. Total number of eggs obtained about 500, 16th to 19th of June.

Larvæ began to appear June 24th. They were fed chiefly on Polygonum acre, and one or two species nearest allied to acre, partly on Polygonum aviculare, var. erectum, and partly on red clover.

Pupation began July 23rd, and continued daily to August 8th, inclusive; a few more pupæ formed to the 16th inclusive, when pupation practically ceased, Only 5 pupations occurred later; two about 20th of August, one about 1st of October, and two in the last ten days of October.

* Gladly giving some attention again to entomology, after several years neglect, I find a few of my former notes, which, as far as they extend, were carefully made, and may be of some use in supplementing other records, or for comparison of localities.
