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-guttata Oliv. , Bassareus inammifer Newra., 

 Cryptocephalus 4-macuIaius Sa\-, C. binominis Newm., C. quadruplcx 

 Newm., C. venustus Fab., C mutabilis Melsh., Pachybrachys othonus

 faushis Hald., P. femoratus Oliv., P. subfasciaius Hald., P. tridens 

 Hald. (one specimen). Babia 4-guttata occurred in ct)nsiderable num- 

 bers on the leaves, which they had devoured quite badly ; of the other 

 species, some were found on the leaves, some on tiie flowers, and man\' 

 were observed on all parts of the plant.

A Stridulating Carabid. 



Having recently set n a statement that Cychrus, Nomaretus and 

 Harpalus among the Carabidx' of this country are known to stiidulate, 

 I may add to the list, Oinopkron. 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 cvanide bottle.
