Mr. Viereck said he could corroborate Mr. Daecke's state- 

 ment on this interesting locality and reported the capture of a 

 bee there, Bombus ternarins Say, which record was the south- 

 ern limit of this species and of a wasp, Pcpsis elcgans St. 

 Farg., which was the farthest north this species has been 

 found. He said Harrisburg seems to be a conjunction of the 

 Alleghenian and Carolinian zones and has evidences of the 

 overlapping of the Canadian and the Austroriparian with the 

 former two. 



Mr. Wenzel commented on Fall's recent paper on American 

 Diplota.vis which includes 95 species of which 50 occur in New 

 Mexico and Arizona, only 3 in Ontario, 5 in all the New Eng- 

 land States and 9 from Pennsylvania and New Jersey. Upon 

 inquiry as to whether this group was determined in the same 

 manner as the Lachnosterna Mr. Wenzel read from the paper, 

 "The male genitalia are quite simple so far as examined while 

 in the female they are entirely membranous and therefore use- 

 less for comparison." 



Mr. C. T. Greene exhibited two flies one of which, Phornia 

 regina Meigen, had been attacked by a fungus which made a 

 complete line around the abdomen at the joints of the seg- 

 ments giving this blue fly the appearance of having yellow 

 bands or stripes and the other, Pollemia rudis Fab., a freak in 

 which the second abdominal segment does not extend the full 

 width. 



Mr. Harbeck said he had taken about 140 specimens of An- 

 drcna, about 6 species, on willow blossoms in a short time at 

 Glenside, April I7th and could have taken a thousand if he 

 had so desired. Adjourned to the annex.
