I have examined the types and a large number of additional specimens 

 from various collections of cylindrica, and the type female of setosa. The 

 new species agrees in general habitus with the other two, differing essen- 

 tially only in being about 8.5 mm. in length and as stated in synopsis. 

 Like setosa, it has the posthumeral bristle single or with a small anterior 

 setulose hair, and the costal setulae are longer than the costal diameter. 

 In color all the species are similar, the only difference being in the color 

 of the femora, as stated in synopsis. 



Type locality of parkeri, Bozeman, Montana, April and May, 1916. 

 Paratype in collection of Montana Agricultural Experiment Station. 



Named in honor of Dr. R. R. Parker, who submitted the material. 



Emmesomyia Malloch. 



The type of this genus is unica Malloch. 



I have examined the type specimens of Spilogaster socialis Stein, and 

 find that the species belongs to Emmesomyia. The only differences that 

 I can find between the types of the two species lie in the comparative 

 lengths of the hairs of the arista and in the slightly larger size of socialis. 

 In the latter the hairs of the arista are much longer than in unica, the 

 longest being distinctly longer than the width of the third antennal joint 

 in the male, while in unica it is distinctly less. Otherwise the species 

 agree closely. An examination of the male hypopygium and of more 

 specimens of each will be necessary to determine the specific distinctions. 

 The fifth ventral abdominal segment in the two species is appi rently 

 structurally the same and quite distinct in armature from that of apicalis 

 Malloch — the only other species known to me. 



Calythea Schnabl and Dzeidzicki. 



Genotype, Anthomyia albicincta Fallen. 



On pages 273 and 274 of their large work on Anthomyiidae Schnabl 

 and Dzeidzicki enumerate the distinctions and affinities of Anthomyia 

 albicincta Fallen, and express the opinion that it should forma new sub- 

 genus of Pegomyia with the name Calythea. 



No mention is made in the discussion of the presence of hairs on the 

 upper anterior portion of the hypopleura, a character sufficiently rare in 

 Anthomyiinae to entitle a species to generic rank. 



The hypopleural hairs associate the species with those in Phaonia, and 

 the hypopygial characters are somewhat similar, but the presence of hairs 

 on the ventral surface of the scutellum, the existence of a bristle on the 

 ventral surface of the basal joint of the hind tarsus, the complete sixth 

 wing- vein, and the general habitus of the species unmistakably connect 

 it much more closely with Anthomyiinae.
