pean authors as a synonym of Wagneria Kobineau-Desvoidy. On 

 examining the type I at first agreed with this disposition of it, but 

 further examination showed that it belongs to Eutrichogena Town- 

 send.® It is, in fact, the species on which Townsend based the genus, 

 Trichogena setipennis Coquiilett, which becomes a synonym. Town- 

 send ^° had stated that NeophoHchaeta johisoni Smith is a synonym 

 of setipennis^ a conckision later accepted by Smith. There is no 

 doubt of the validity of EutricTiogena); hence Walker's species should 

 be called Eutrichogena clesides. Meanwhile Townsend ^^ had pro- 

 posed the new genus Neophyto for Coquillett's sefosa, which is not a 

 Pliyto. This has been generally accepted for years; Coquillett's 

 species is therefore Neophyto setosa. It has no postscutellum, and I 

 think it belongs to the family Sarcophagidae. 



Tachiiia tlieutis Walker, List, p. T78. Coquiilett (p. 52) placed 

 this in its proper genus, Gryptomeigenia Brauer and Bergenstamm. 

 I took full notes on the type, a male from Nova Scotia. The genus 

 contains several North American species, which show modifications 

 of the ovipositor in the female available for specific distinction in at 

 least a part of the series. A revision of the genus is now in progress 

 and will probably be published shortly after the present paper; 

 hence it is not desirable to discuss the specific characters here. 



Tachina prisca Walker, List, p. 780. Coquiilett (p. 52) placed 

 this as a synonj^m of the preceding, and it certainly belongs to the 

 same genus. The type is a female from Nova Scotia, different from 

 theutis^ on which I took notes that will be used in the forthcoming 

 work just mentioned. 



Tachina convecta Walker, Insecta Saundersiana, p. 276. 

 Walker had already, page 264, established the genus Schizotachina 

 for this and his Tachina eocul, immediately following it. Coquiilett 

 (p. 55) made eanil a synonym of convecta^ which was a very natural 

 course, as the descriptions are almost exactly the same. Both were 

 from " United States." I was surprised on examining the type of 

 convecta to find that it did not match the specimens I had with me. 

 My notes run : 



One male, United States. It is in good condition as to antennae and abdo- 

 men. I note first an absence of the interruptions of the basal silvery bands 

 on second and third abdominal segments. The band seems entire on the second 

 and only interrupted in the middle on the third ; although narrow in a certain 

 light, they are not so sharply limited as in my two males. The band is in- 

 distinct on the fourth segment laterally, perhaps on account of condition. The 

 discal row of bristles on the fourth segment is distinctly behind the middle ; not 

 so in mine. The narrowest part of the parafacial is much wider than in my 

 males, and the bristles of the facial ridges are only four, on lowest one-third 

 or two-sevenths. Wings a little milky.
