Tachina pyste Walker, List, p. 754. Coquillett (p. 93) placed 

 this in Exorista. The type is a female and agrees with the deter- 

 mination of Coquillett. Aldrich and Webber ^* make pyste a syno- 

 njaii of Tnaculosa Meigen of Europe, which Stein ^^ puts as a syno- 

 n3^m of -floralis Fallen. Brauer and Bergenstamm had referred 

 American specimens to the genus NemoHlla Rondani for Coquillett, 

 and this genus is now generally accepted for the species. Hence 

 Tachina pyste Walker should be called Nemorilla -floraUs Fallen. 



Tachina epicydes Walker, List, p. 786. Coquillett (p. 94) 

 placed this as a synonym of ExoHsta affinis Fallen. The type is a 

 male from Martins Falls, Albany River, Canada ; it runs in the key of 

 Aldrich and Webber to Zenillia coerulea^ new species, and agrees 

 with the description perfectly except that it appears to have true 

 discals. The abdomen is rubbed and this point is not clear, but I 

 accept the synonym}^, sinking coerulea. 



Eurygaster septentrionalis Walker, in Lord's " Naturalist in 

 Vancouver Island," vol. 2, p. 339, 1847. Coquillett (p. 102) placed 

 tliis as a synonym of Euphorocera cJaripennis Macquart. I did not 

 find the type in the British Museum. The description is vague and 

 incomplete, but reads like a Phorocera. It is as follows : 



Euryijaster septentrionalis, N. S. Foem. — Nigra, setosn, latiuscula ; capite 

 argenteo-cinereo ; vertiee aurato ; frontalibns atris ; palpis rufescentibus ; an- 

 tennis aristae dimidio incrassato ; thorace vittis quinque cinereis ; scutelli 

 apice piceo ; abdomine cinereo subtessellato ; alis cinereis. 



Female. — Black, setose, rather broad. Head silvery cinereous, gilded above ; 

 frontalia deep black, widening in front ; facialia bordered with bristles aloug^ 

 most of the length from the epistoma. Palpi reddish. Antennae extending 

 to the epistoma ; third joint linear, rounded at the tip, full six times the length 

 of the second ; arista incrassated for half its length from the base. Thorax 

 with five cinereous stripes; scutellum piceous at the tip. Abdomen slightly 

 tessellated with cinereous, very bristly toward the tip, a little longer than 

 the thorax. Wings cinereous ; veins black ; prebrachial vein forming an obtuse 

 angle at its flexure, straight from thence to its tip. [Length omitted.] 



Tachina melobosis Walker, List, p. 743. Coquillett (p. 105) 

 could not identify any specimens as belonging to this species, and 

 placed it doubtfully as a Phorocera. I saw the type, a male from 

 Florida, but had nothing with me to match it, nor can I find the 

 species in the National Museum ; hence I quote the description I made 

 from the type : 



Much resembles LypTKi dubia Fallen in having hairy eyes, large pteropleurals, 

 abdomen thick apically and with discals, the first genital segment shining black 

 and rather large and conspicuous. However, melobosis has much longer an- 

 tennae, and the penultimate joint of the arista is elongate. 



Outer vertical larger than a hair ; ocellars proclinate and divergent ; 2 re- 

 clinate frontals, 10 others to second fifth of third antennal joint, fully meeting
