scribed some appearances in the pupe of Hudamus Tityrus, by which 
he thought it might be possible to know the sex of the pupz. 
Mr. Mann described some great variations in the appearance of larve 
which afterwards produced female imagos of Anisopteryx pometaria. 
Mr. Scudder referred to the presence of Gryllus domesticus in several 
parts of the country, into which it had been introduced from various 
parts of Europe. He had not succeeded in an attempt to naturalize the 
species in Cambridge, the specimens which he had, that had come to 
Boston from some undetermined source, in an East India merchant-ves- 
sel, having been destroyed by accident. 
Upon the table lay an Entomologists’ Bulletin in manuscript, which 
had been prepared by Mr. Mann, and contained the addresses of about 
three hundred North American entomologists, with a notice of the 
special pursuits of each, when known, and such other information of a 
similar kind as would be of interest to entomologists. This Bulletin 
was open to the inspection of all who wished to see it, and all were re- 
quested to communicate to Mr. Mann such information as would enlarge 
and freshen this record. 
April 14, 1876. Dr. Hagen gave a very interesting account of the 
mode of gathering, and of some of the properties of amber. 
Mr. Scudder exhibited specimens of Oyaniris lucia, Q, violacea, 0. 
neglecta, and C. pseudargiolus to illustrate a paper which he read, showing 
that these so-called species are probably only forms of one species, which 
must retain the name of Cyaniris pseudargiolus. ; 
Dr. Hagen gave some information about an insect allied to Mantispa 
(but possessing an ovipositor), which he had lately received from Lieu- 
tenant Wheeler’s Expedition, as having been caughtat Fort Tejon, South- 
ern California. This is the more interesting, as no Hemerobina, except 
its congeners and the species of the genus Dila, possess an ovipositor. 
The insect lives in wasps’ nests. 
Mr. Scudder said that in working up the Forficularians of North 
America, he had detected thirty-eight species; there are undoubtedly 
m more, especially in Mexico. Only fourteen species are found in 
the United States and only nine of these are indigenous. Mr. Scudder 
has prepared a synoptical table of the United States species for publica- 
tion in Psyche. 
Mr. Austin said that on the 26th of March he obtained at least twenty- 
eight species of Dytiscidæ in a small clay pit which had become filled 
with water. Some of the species occurred in immense numbers. De 
- Hagen suggested that the absence of fishes would account for the great 
abundance of these beetles. .
