ART. 9 TWO-V/INGED FLIES OF TRIBE MILTOGRAMMINI ALLEN 21 



Costa, near the humeral angle, with appressed hairs; inner forceps of male 

 genitalia elongate and linear when viewed from behind nana Coquillett. 



UNRECOGNIZED SPECIES AND OTHERS MENTIONED BY ALDRICH '* AND BY 



COQUILLETT '^ 



biseta Thomson, Kong. Sven. Freg. Eugenics Re.sa, p. 524, 1868. There is 

 no record of this species since the type w^as described from Panama in 

 1868. From the description is seems probable that the species belongs 

 in Senotainia, but its exact position is rather uncertain. 



erythrocera Thomson, Kong. Sven. Freg. Eugenies Resa, p. 523, 1868. This 

 species from California is described as possessing a long, pale, shaggy 

 beard, three sternopleural bristles and discal bristles on the fourth abdomi- 

 nal segment — characters sufficient to place it outside the limits of Seno- 

 tainia, and in all probability outside the subfamily Miltograniminae. 



sarcophagiJia Van der Wulp, Biol. Cent. Amer., Dipt., vol. 2, p. 90, 1890. 

 Major Austen reexamined the type in the British Museum for me, finding 

 that the specimen possessed two rows of frontal bristles on each side of the 

 frontal vitta. He writes that it is certainly a Pachyophthalmus, to which 

 genus it has been assigned. 



erythrura Van der Wulp, Biol. Cent. Amer., Dipt., vol. 2, p. 89, 1890. 

 Major Austen, who has examined the type in the British Museum for me 

 states that this species is also a Pachyophthalmus, to which genus it has 

 been assigned. 



fuhicornis Van der Wulp, Biol. Cent. Amer., Dipt., vol. 2, p. 89, 1890. 

 Described from type and one other female from Guerrero, Mexico, and 

 assigned to Miltogramma. Type in British Museum reexamined for me 

 by Mr. Barnett who states that "the type does not possess a pair of 

 marginal bristles at the apex of the second abdominal segment; the tibia 

 of the hind leg is equipped with a more or less complete row of bristles 

 on the outside; there are more than ten bristles in the frontal row on 

 either side of the frontal vitta; the eyes are nearly twice as high as wide.'" 

 These characters serve amplj' to distinguish it from rubriventrts with 

 which it has been considered synonymous. Major Austen states that it 

 is a Sphixapata, which equals Senotainia. He has compared the type 

 with a specimen of Senotainia flavicornis Townsend determined by me 

 which possesses all the characters listed above for the type of fulvicornis, 

 and states that they are certainly not conspecific. It does not appear 

 to be identical with any other species discussed in this paper and must 

 represent a distinct species which I am at present unable to place. 



nana Van der Wulp, Tijdschr. v. Ent., vol. 35, p. 195, 1888; Biol. Cent. 

 Amer., Dipt., vol. 2, p. 483, 1903. Described and assigned to Milto- 

 gramma; type, a female from Guerrero, Mexico, has been lost. I find it 

 impossible to definitely determine the place of this form from the super- 

 ficial nature of the description. It has not been repoi-ted since its descrip- 

 tion over 35 years ago. It may belong to the genus Senotainia, and is 

 most certainly distinct from nana Coquillet and other species of the genus 

 mentioned in this paper. Unless the type should be found, the name 

 might best be disregarded. 



fasciata Coquillett, U. S. Bur. Ent., Tech. Ser., No. 7, p. 81, 1897. Equals 

 Eumacronychia elita Townsend.
