breeding in confinement two were found dead as eariy as April 21st, a 
larva was taken as Jate as May 4th anda pupa was placed in alcohol 
May 22d. The adult insects feed upon the leaves of the locust. Latest 
capture was on June 21st. 
Brachys ovata Web.—Mines the leaves of oaks. 1 have seen one 
speciinen tred from an oak leaf. 
B. «rosa Melsh.—Occurs commonly on elins. 
My observations on the following species coincide substantially with 
Mr. Blanchard’s list. Decerca durida Fab., under stones in early spring. 
Chrysobothris scabripennis Lap. & Gory on white pine in May and June. 
Lupristucerus cogitans \Veb. on alder, Agrilus bilneatus Web. and A.

Cryptocephalini found on Ceanothus Americanus. 
The following is a list of some of the species of Cryptocephalini 
taken at Ithaca, N. Y. in July on the New Jersey tea plant (Ceanothus 
americanus). Babia 4-guitata Oliv., Bassareus mammifer Newm.., 
Cryptocephalus 4-maculalus Say, C. binominis Newm., C. quadruplex 
Newm., C. venustus Fab., C. mutabilis Melsh., Pachybrachys othonus 
Say, P. ¢rinotatus Melsh., P. sobrinus Hald., P. duridus Fab., P. in- 
Jaustus Hald., P. femoratus Oliv., P. subfasciatus Hald., P. tridens 
Hald. (one specimen). Aadbia g-gu/ta/a occurred in considerable num- 
bers on the leaves, which they had devoured quite badly ; of the other 
species, some were found on the leaves, some on the flowers, and many 
were observed on all parts of the plant. 
Many other Coleoptera frequent C. americanus, among others many 
species of Mordellidze, Malachudae and Cistelidze. Cvs/e/a sericea Say, 
often occurs in such numbers as to almost exclude all otber species.

A Stridulating Carabid. 
Having recently seen a statement that Cychrus, Nomarefus and 
Harpalus among the Carabidee of this country are known to stridulate, 
I may add to the list, Omophron. During the past season I have re- 
peatedly observed the habit in O. americanum, Dej. and I have no 
doubt that many other genera will be found to have stridulating habits, 
if collectors will only be careful to observe them before consigning them 
to the alcohol or cyanide bottle.
