Xylota bicolor and chalybea, Criorhina umbratilis and analis, 

 Sphecomyia vittata, Teuchocnemis lituratus and Temnostoma 

 pictnla. It is also the type locality of Symphoromyia hirta 

 (June 2), Neaspilota achilleae (July 4), Pipunculus atlanti- 

 cus (June 2), and Tetragoneura pimpla (June 16). One trip 

 was made to Arcola on the Perkiomen River, April 27, 1894. 

 Pipiza albipilosa was abundant there. Fairmount Park is the 

 type locality for this species, and also for Pipiza nigripilosa. 



In Bucks County, Neshaminy Falls and vicinity were the 

 principal collecting grounds, but the amount of material col- 

 lected was limited. 



The label "Delaware Co." stands for several places covered 

 by about eight collecting trips. The woods between Folsom 

 and Morton yielded many new and interesting species. It is 

 the type locality for Asilus johmoni (July 7), Atomosia sayi 

 (July 23), Empis tridentata (June 12) and Haematopota rara 

 (June 12). My only specimens of Criorhina notata and of 

 Teuchocnemis bacuntius were taken there May 8, while such 

 species as Odontomyia flavicornis and Trichopoda radiata were 

 taken frequently. Another favorite trip was up the valley 

 from Darby to Collingdale and then through the woods to the 

 home of my friend, Mr. Charles Voelker, at Clifton Heights. 

 In the spring (May 5) an old log near Collingdale was usually 

 frequented by Chalcomyia aerea, Pseudotephritis corticolis and 

 Leptis plumbea. Brachyopa vacua was frequently found on 

 the sap of injured trees or stumps. Solva americana and Ech- 

 thodopa fonnosa were found in the woods at Clifton Heights. 

 August 19, 1892, was spent with my friend, Mr. Charles S. 

 Welles, at his home at Elwyn. Among the captures were two 

 new species, Leskia thecata and Plethochaeta versicolor. At 

 Media (June 21, 1895) I captured a specimen of Microdon 

 mcgalogaster. 



In Chester County, collections were made at Frazer, July 

 25, and Lenover, August 25, 1893. Later some collecting was 

 done at Green Tree. 



In this connection I should also like to refer to the locality 

 label "North Mt, Pa." This applies to all species taken at
