except a few very slight ones. Webber, hoATever, in revising the 

 genus Achaetoneura,^'^ has left this out; it may stand for the present. 



Tachina violenta Walker, List, p. 788. Coquillett (p. 108) 

 identified this as a species of Frontina. The type is a male from 

 Nova Scotia, and is the same species described on an earlier page by 

 Walker as panaetius, which I take for the valid name. It is the 

 same species described by Townsend as Tachinomyia rohusta.^^ In 

 Ciirran's key to the species of Tachinomyia ^^^ the type runs to couplet 

 3, but I did not venture to spread the genitalia and could not posi- 

 tively exclude variata Curran, which, however, seems at most not 

 more than a subspecies of robusta. The genus TacMnoinyia is a 

 distinct one, hence violenta in my opinion is a synonym of Tachino- 

 w/yia panaetius Walker. 



As to the species misidentified as violenta by Coquillett, the speci- 

 men with Coquillett's label on was included in Achaetoneura testacea^ 

 new species, by Webber.*^ Coquillett placed Masicera dubia Willis- 

 ton ** and Masicera sphingivora Townsend *^ as synonyms of his 

 supposed violenta. Webber has discussed these on pages 36 and 37 

 of his recent revision. , 



Tachina irrequieta Walker, List, p. 788. Coquillett (p. 108) 

 placed what he identified as this species in Fronting. The type is 

 a female of Tachinomyia panaetius Walker. 



The species misidentified by Coquillett as irrequieta is included as 

 Achaetoneura rileyi Williston by Webber in his revision of Achae- 

 toneurc(\; *° Coquillett had already indicated the synonymy of this 

 si:)ecies with the supposed irrequieta. 



Tachina dydas Walker, List, p. 748. Coquillett had no speci- 

 mens Avhich he could identify as this species, and placed it (p. 108) 

 as a doubtful species of Frontina. Major Austen*^ published a note 

 on the type, making it a synonym of Eutachina rustica Meigen. I 

 agree with this disposition after examining the type; but it seems 

 that simulans Meigen has some years priority for the species, and 

 the genus Eutachina has little to stand on as against Tachina of 

 authors {=Exorista Meigen according to strict rules, as larvarum 

 Linnaeus was the only species originally included in Exorista). On 

 this basis the species becomes Exorista simulans Meigen. 



Tachina obconica Walker, Insecta Saundersiana, p. 296. Co- 

 quillett (p. 110) placed this as a synonym of Sturmia alhifrons 

 Walker. The type is a female, not a male as Walker thought, and is
