man, LeConte, and others. He exhibited a number of manuscript 
and rare printed books from this collection. Some of the manu- 
script volumes contain original descriptions, with colored fig- 
ures of larvae raised by Melsheimer, with notes on the habits of 
larvas ; others contain descriptions of genera and species of in- 
sects, compiled or original, intended apparently for a faunal work ; 
others contain transcripts of scientific writings which Melsheimer 
had been unable to purchase. One quarto volume contains a 
list of Coleoptera (probably those of Pennsylvania) , with notes 
on the season, food-plants, and habits of many species. Among 
the printed books there was a copy of the Catalogue of the Cole- 
optera of Pennsylvania, by the elder Melsheimer, published in 
1806, with manuscript additions and corrections by Melsheimer. 
Mr. Lugger gave a list of insects which he had noticed out- 
doors this year very late in the season. They are species not 
usually found at this season. The list is as follows : 
Oct. 19. Leptostylus aculifer, found on the electric light in Baltimore 
during a cold and windy evening. 
Oct. 21. Attacus luna <$, flying about a street-lamp in front of his house 
in Baltimore ; weather rainy and cold. 
Oct. 26. Chcerocampa tersa, found flying during a sunny afternoon in 
the Agricultural Grounds. 
Oct. 27. A very large swarm of Cotton Moths (Aletia xylina) at the 
electric lights on Capitol Hill. Wind due west; all the specimens were 
fresh (Schonborn). 
Oct. 27. A few Cotton Moths at the electric light in Baltimore, but only 
at elevated points. 
Oct. 28. All the streets in Baltimore provided with electric lights were 
crowded with Cotton Moths. The same phenomenon occurred six years 
ago, during a heavy rainstorm. It was so cold at that time that snow- 
flakes were mixed with the rain, and snow remained on the streets until 
the following noon. Specimens quite fresh. 
Nov. i. Scepsis fulvicollis; one specimen flying about at Washington. 
Nov. 8. A few Cotton Moths flying about the electric lights on Capitol 
Hill (Schonborn). 
Nov. ii. Colias eiirytheme, or rather a very pale variety of it, looking 
like Pieris, was flying about some flowers of Dandelion in the Agricul- 
tural Grounds. 
Nov. ii. A female of Mantis Carolina was found in the Smithsonian 
Grounds. 
NQV. 12. A fresh specimen of Cicada pruinosa was taken at the same 
place.
