A cuinmunication was read from Dr. Leconte anuuuiicing that during 

 the months of July and August, at Bedford Springs, in Bedford Co. Pa., 

 he collected the following species of Coleoptera, of unusual occurrence : 



Chlsenlus chlorophanus. Chlsenhts prasinus. Cerlius Ziegleri, Bry ax- 

 is longuhis. Batrisus globosus. Eitryuaa n. sp., and ffomalota? n. sp.,a.l\ in 

 the hills formed by a species of ant of a brown color, with a piceous abdo- 

 men. Bri/oporus . Rlii/asodes covjungens. Bdcanms tantiUus. 



Helirhuti fa»tigiatus. Udirhiis ^/</ioj>At?».s, very abundant, flying at night; 

 and also under stones beneath the water of streams. Serica iricolor. 

 Cupes capitatu. Xyletinua n. sp. Trijpop)itys sericeus. Oligomerus er- 

 rnns. 3fi/odites fasciata, on Solidago. Brachy tarsus tomentosiis. 



Also a communication from Mr. Newman, calling the attention of the 

 members to specimens of the larvse of Dryocampa imper talis, and Cerato- 

 ravipa rcgalis, exhibited by him this evening. The larvae of Dryocampa 

 imperialis varies very much in color, some being a beautiful green, and 

 others jet black. The perfect insect also varies, some specimens being 

 darker than others. He also states that he has bred 28 larvae of Cerato- 

 campa regalis, most of which have gone into the ground to transform, and 

 to appear as perfect insects in July next. 



Also a communication from Mr. Bland, reporting the capture of the fol- 

 lowing Coleoptera: Cicindela ahdominalis was found running on a white 

 sandy road in Atlantic County, N. J., on the 4th of last month. 



On the 2oth of August, in Camden County, N. J., he found Euryomia 

 inda abundant on Vernonia novemboracensis ; also Tritoma higuttata abun- 

 dant in fungi. 



Mr. Bland also states that from his experience in collecting aquatic Co- 

 leoptera during the past two months, he has found the early part of Aug- 

 ust the best time. The plan he adopted was to gather the moss and weeds 

 from the sides of swamps, and wash them in a close muslin net. Collectors 

 will thus find their labors rewarded by many minute species which cannot 

 be otherwise obtained. 



Also a communication from Mr. Cresson, stating his belief that there are 

 two broods of Sphyracrphala hrevicornis during the year. It suddenly 

 reappeared on the 20th of August in the same locality as before reported, 

 but on grass and weeds instead of skunk cabbage, which had disappeared. 



The best time to collect them is at sundown, by sweeping with a net, 

 the grass and weeds growing in a damp and shady situation ; at this time 

 they are quite inactive and easy to capture.
