imago of Tarquinius. I have taken it in several years, in April, from 

 17th to end of the month and 5th May. Again in June, from 14th to 

 4th July; on this latter date I took 24, in 1868, and saw large numbers 

 more ; and again last of July, in several years. And I have repeatedly 

 bagged the females on hawthorn, led thereto by what Prof. Glover told 

 me, but always have failed of getting eggs. I have taken these examples 

 generally up the branches of the creeks, flying about the stones in the 

 nearly dry beds thereof. I remember that on the occasion spoken of 

 when I took so many, the butterflies persisted in visiting a large stone, 

 and I caught most of my examples by a bottle, so tame were they. So 

 far as I know there were no alders or hawthorn within a mile of the 

 points where the butterflies have been abundant. There were plenty of 

 beeches, but the probability is that many trees or shrubs on which there was 

 a good supply of aphides would attract the females. 



I know nothing about the broods of this species at the north. As we 

 have seen, eggs and larvae were found at New Windsor from middle of 

 August to last of September. 



Note. — After the above lines had been sent to printer, on 4th Oct., I 

 received three nearly mature larvae of Tarquinius from Mr. Henry F. 

 Schonborn, at Washington, D. C. , on alder. No information was received 

 respecting these larvae.

A small round box of bamboo (8 by 6 inches) was bought nine years 

 ago in Hong Kong, China, and brought home to Boston. It was placed 

 on a little shelf on the wall, and used for Turkish tobacco. The box was 

 lined inside with a perfectly closing box made of East Indian block-tin, 

 about a miUimetre thick. I examined the box January, 1885, and found 

 it hollowed throughout like a sieve, and containing between the tin box 

 and the bamboo cover a large number of dead and living beetles and two 

 living larvae. The tin box had four small round holes apparently cut 

 through by the insects. The beetles represented two species, one, a little
