A PRELIMINARY LIST OF THE FLIES OF WISCONSIN 



BELONGING TO THE FAMILIES BOMBYLIID^, 



SYRPHID^ AND CONOPID^. 



By S. Gr a en i cher. 



Our acquaintance with the insect fauna of this State is still 

 so unsatisfactory that a list of this kind can not be considered 

 more than a simple registration of the facts in our possession at 

 the present time, from a few sources only. Owing to the ardor 

 of some of our local entolomologists the immediate surroundings 

 of Milwaukee have been pretty thoroughly canvassed for some 

 groups of insects, and as a result records have been obtained that 

 form a nucleus for comparison with the records from other parts 

 of the State. Nearly 10 years ago the writer published a list of 

 the Syrphidw of Milwaukee County (Bull. Wis. Nat. Hist. Soc, 

 July 1900; pp. 167-177), in which 64 species were enumerated. 

 Since that time, partly through the efforts of Dr. G. P. Barth of 

 Milwaukee, partly through my own observations the following 

 17 species have been added to the Milwaukee list for this family: 



Chrysogastcr nigripes, Chilosia prima, Eupeodes volucris, 

 Xantho gramma emargiiiafa, X. tenuis, X. divisa, Volucella evecta 

 V. vesiculosa, Sericomyia chrysotoxoides, Bristalis saxorum, 

 Helopkilus bilinearis, Tcuchocnemis lituratus, Criorhina inter- 

 sistens, Xylota angustiventris, Spilomyia hamifcra, Temnostoma 

 bombylans, and Ceria abbreviata. 



I am also indebted to Dr. Barth for a number of records from 

 other points in the State, mainly from Wausau, Marathon 

 County, Wis. 



The collection of the Public Museum of Milwaukee contains 

 a large number of species of the three families under consideration, 

 among them some interesting material collected by Mr. C. T. 

 Brues on two collecting expeditions of the Public Museum to 

 northern parts of the State, one in 1905 to the Door Co. peninsula, 

 the other 1907 to Vilas Co. and the Lake Superior region around 

 Ashland. In this latter lot I have come across a new species of
