1911] Graenicher, Wisconsin Diptera. Supplement. 67 



Anthrax. 



A. alternata Say. Two specimens from. Hudson (St. Croix Co.), 

 three from Prescott (Pierce Co.), and one from Maiden Bock (Pierce 

 Co.). 



A. fulvohirta Wiedemann. Not at all rare at Hudson (St. Croix 

 Co.), and Prescott (Pierce Co.), where altogether eighteen specimens 

 were obtained. Only one specimen has been taken in eastern Wiscon- 

 sin (Milwaukee), so far. This is a species of southern distribution, 

 and in Wisconsin it has not been met with farther north than Hudson. 

 It has been reported from Minnesota {Diptera of Minnesota, Tenth 

 Annual Eeport of the State Entomologist of Minnesota, 1905), but no 

 locality given. 



A. halcyon Say. Two specimens from Maiden Rock (Pierce Co.) 

 are the only ones on record from western Wisconsin. 



A. lateralis Say, var. gracilis Johnson. A rather common Bomby- 

 lid along the Mississippi river. Specimens from St. Croix (Hudson) 

 and Pierce Cos., (Prescott and Maiden Bock). 



A. morio Linne. Two from Hudson (St. Croix Co.) and three 

 from Prescott (Pierce Co.). 



A. nemakagonensis Graenicher. Seven specimens from Hudson 

 (St. Croix Co.) and ten from Prescott (Pierce Co.) agree in detail 

 with the type and cotypes from the St. Croix region. 



A. sinuosa Wiedemann. Four from Hudson (St. Croix Co.) and 

 five from Prescott (Pierce Co.). 



Bombylius. 



B. fulvibasis Macquart. Fairly common at Hudson (St. Croix 

 Co.) and Prescott (Pierce Co.). No specimens were taken farther 

 south, undoubtedly on account of the lateness of the season. All of 

 those collected at Prescott around July 20th bore the marks of old 

 age (torn wings, and most of the pubescence of the body rubbed off). 



Systoechus. 



S. candidulus Loew. This species was described by Loew (Centur. 

 IV, 51) from a specimen from Wisconsin. Later Osten-Sacken (West- 

 ern Diptera, p. 253) reported it from Illinois and Kansas, but since 

 that time nothing- has been heard of it, so far as our knowedge goes. 

 One male taken at Prescott (in Pierce Co.) has the scutellum more
