daries, general shape of the female genital plate, and cremaster of pupa approach those of the remingtoni group of the marine complex. The maculation of the primaries and what is known of the life history would indicate a baueri complex relationship. When more information is known this species may well represent another species complex.
Host plant: Agave tequilana Weber.
Life history: What is known of the life history of this species was observed at the type locality by Stallings and Turner on 24 August 1957, while they were collecting the larvae. They inform me that the tan trap doors were on either side of the leaf and that the day that they were found the larvae were cutting holes in the leaves just prior to making their trap doors. Some of the burrows were not powdered on that date while others were. A few larvae used two leaves with their burrow, while most used but a single leaf. There was no frass to be observed anywhere. The larvae were a sordid green with pink tints. Pupae resemble those of the rnar'ue complex in general shape and size.
I wish to express my deepest thanks to the National Science Foundation for a very generous research grant, making it possible for me to continue my work with the Megathymidae.

CAPTURE OF NYMPH J LIS J-ALBUM IN MARYLAND
AT NIGHT
This note was stimulated by the observation of Bryant Mather (1959) concerning the capture of butterflies at night and by his restatement of the Editor's desire for further information in this field.
On the night of August 22, 1941, I noticed a perfect specimen of Nymphalis j-album Boisduval & Leconte hanging from the light fixture of an open side porch oi a friend's house in a northern residential section of Baltimore city. It was easily captured because it seemed to be lethargic and I simply knocked it off into a killing jar.
This capture is of interest in that it occurred at 9 p.m. and in that it is the first recorded capture of this species in Baltimore since that of Otto Lugger in 1882 (January 2nd!) as reported by Clark (1932).
