near Holmes, Delaware County, Pa., August 29, 1911, taken 

 by himself; very few records of these species from this neigh- 

 borhood exist. A male of E. civile Hagen from the same 

 pond and date is of interest because of its additional black 

 asymmetrical spots on abdominal segments 3 and 4. 



This led to a general discussion on the different forms from 

 warm and cold climates and Mr. Wenzel, Sr., exhibited his 



4 



collection of Cicindelas dorsalis group to bear out his state- 

 ments. 



Dr. Skinner said they have had considerable trouble at the 

 Academy, caused by Dermestids infesting the mounted heads 

 hanging about the museum. He found upon examination that 

 they were a Californian and New Mexican species. Trogoder- 

 ma sternale Jayne. Mr. McCadden claims they do not injure 

 the hair but feed on the cartilage left on the bones and at the 

 base of the horns. 



Mr. Daecke said someone at Harrisburg had complained to 

 him of numerous mosquitoes breeding in a certain place. He 

 had gone to this water hole and spread three gallons of oil on 

 the surface and immediately the water beetles came up for air 

 and were easily captured with a net many specimens were 

 taken. Dr. Skinner said it might be possible to obtain the 

 same result with fish poison as used by the Indians in New 

 Guinea. 



Mr. C. T. Greene exhibited the Rhyphus alternatus Say 

 (Dip.) reported at the last meeting. 



Mr. Geo. M. Greene exhibited Metathorasa monetifera Gn. 

 (Lep.) collected by C. T. Greene, Lehigh Gap, Pa., vii-7-o7-
