Eustalomyia vittipes Zett. (Anthomyidae'). 



In describing the male of this species, Mr. P. Stein com- 

 ments upon the rarity of the fly in collections. It may be of 

 interest, therefore, to record the fact that this fly has twice 

 been reared from material collected from the interior of rotten 

 logs in the winter season at Harrisburg, Pa. The insect was in 

 the pupal stage and upon both occasions was in close proximity 

 to cells of hymenopterons. Collections made by Paul Myers 

 and A. B. Champlain. The following hymenopterons were 

 reared in connection with it. Crabro (Xestocrabro} trifas- 

 ciata Say. Crabro maculatns Fabr., Thyreopns (Blepharipns) 

 impressifrons F. Sm. and Pcmphredon concolor Say. 



The puparium is chestnut brown, 8 to 9 mm. in length and 

 from 2 1-2 to 3 mm. broad. Dorsally extremely polished, ven- 

 tral side minutely wrinkled between the segments. 



Ectecephala albistylum Macq. 



Type locality North America. This rather curious Oscinid 

 seems to have escaped recording for some reason. It seems 

 to be not uncommon in the vicinity of Harrisburg, Pa., Mr. 

 W. S. Fisher having swept it from grass on several occasions, 

 and the writer has also taken it in Harrisburg. Mr. D. W. 

 Coquillett has confirmed our determination. 



Pyrellia serena Meigen. = = (P. cyanicolor Loew.). 



This Muscid, apparently adventitious from Europe, appears 

 to have been overlooked by collectors ; it is rather common in 

 Pennsylvania, but as it resembles superficially the much more 

 common Morellia tnicans, its presence in collections possibly 

 remains unsuspected. 



The distinguishing characters may be summarized as fol- 

 lows: Color of body, dark steely blue, occasionally greenish 

 blue; thorax with three longitudinal, rather faint, hoary 

 pollinose stripes. Sterno-pleural bristles 1-3; a stout bristle 

 on the flexor surface of the middle tibia, first posterior cell 

 rather widely open, 4th vein being only gently curved forward. 



I first recognized this species among some Muscids collect- 

 ed by Mr. Erich Daecke, on the flowers of Trillium erectum,
