thirds eye. Parafrontalia gently narrowing posteriorly, a little 

 narrower than frontalia. Frontals descending obliquely two 

 below base antennae. Parafacialia less than half as wide as 

 clypeus, with row of bristly hairs doubled below. Cheeks little 

 over one-fourth eye-length. Three postsuturals, preacrostichals 

 present. Squamae longer than wide. No median marginals 

 on second segment, strong marginal row on third segment. 

 Hypopygial tergum entire. Genotype, Sarcophaga amblycory- 

 phae Coq., Proc. Ent. Soc. Wash., vi, 187 (1904). 



Notochaetopsis, new genus. 



Differs from Sarcophaga as follows : Proboscis shorter than 

 head-height. Eyes large. Vertex in both sexes about two- 

 fifths eye, the front narrowing conspicuously in front of ocellar 

 area. Frontals descending obliquely two below base antennae. 

 Outer verticals developed in both sexes, but short. No 

 proclinate fronto-orbitals in either sex. Ocellars present. 

 Parafacialia of female half as wide as clypeus, those of male 

 two-thirds same ; with single row of bristly hairs. Cheeks 

 about one-third eye-length in both sexes. Three postsuturals, 

 preacrostichals present. Lateral scutellars two. Squamae 

 longer than wide. Hind tibiae of male not villous. No median 

 marginals on second segment ; third segment with strong 

 median marginals. Hypopygial tergum of female entire ; sec- 

 ond and third hypopygial sternites forming a short broad 

 sheath to the larvipositor, the third showing thin and trans- 

 lucent. Genotype, Sarcophaga masculina Aid., Sarc. and 

 Allies, 130 (1916). 

 Camptopsis, new genus. 



Differs from Sarcophaga as follows : Female. Arista short- 

 plumose less than halfway. Eyes very large. Vertex about 

 three-fourths eye. Parafrontalia almost as wide as frontalia ; 

 frontals not descending below base antennae. Outer verticals 

 very short, stouter but scarcely longer than occipital fringe. 

 Only one proclinate fronto-orbital. Ocellars weak. Para- 

 facialia scarcely one-third as wide as clypeus, with only a few 

 microscopic hairs on upper extent in continuation of row on 

 parafrontals. Cheeks hardly over one-seventh eye-length.
