tip ; apical cell widely open; macrochaetae marginal on last three 

 segments, with irregular discals on anal segment; front tarsi of 

 female widened ; palpi phylliform, but not very broad; scutellum 

 with erect short straight spines. 



This genus appears to be confined to Africa. 



Thelychaeta, B. B. 



Genotj^pe, Thelychaeta chalyhea, B. B. — Borneo. 



Facial carina iDroad, but flattened; epistoma Phasia-\\k&, 

 broad and very long ; arista wholly long-plumose to tip ; apical 

 cell widel}^ open; male eyes almost contiguous, the frontalia near- 

 ly or quite pinched out, the parafrontalia reduced to a line; male 

 hypopygium not very large, claws not very long ; macrochaetae 

 like Pollenia; front tarsi of female much widened, those of male 

 scarcely so; palpi phylliform; female with two strong proclinate 

 fronto-orbitals and one reclinate, male with none of either. No 

 straight erect spines on scutellum. 



Thelychaeta chalybea, B. B. 



One female, labelled " no history." This specimen differs 

 from the description by the third antennal joint being scarcely 

 twice the length of the second. It is strongly bluish, and the 

 abdomen shows practically no pollen. The tegulae are strongl}' 

 infuscate with brownish, the wings but faintly so. The form is 

 evidently congeneric with viridaurea, Wd., and is doubtfully re- 

 ferred to chalyhea, B. B. 



Thelychaeta viridaurea, Wied. 



One male and six females of this interesting species are from 

 Mergui, Lower Burma; Ghumti, Eastern Himalayas, 1,800-3,500 ft. ; 

 Sadiya, North-east Assam; and Soondrijal, Nepal; three others 

 being labelled " no history." Wiedemann's characterization, though 

 very brief, seems quite unmistakable. Brauer and Bergenstamm 

 have given additional characters {Muse. Schiz., Ill, 179), Wiede- 

 mann's specimen was evidently an undersized female. The pre- 

 sent specimens measure 10 to 11 mm. The colour is golden-green, 

 more or less cupreous; the abdomen with changeable pollen like 

 Pollenia rudis, F., but greenish-gold. The male generic characters 

 above are drawn from this species. 



Pollenia, R, D. 



Genotype, Musca rudis. Fab. — Europe, Asia, North America 

 (evidently introduced in last). 



Facial carina acute, sharp, narrow; epistoma Phasia-MkQ, 

 very narrowed ; arista plumose to tip ; apical cell widely open ; 

 male eyes not contiguous, but rather closer together than length 

 of second antennal joint, the frontalia practically pinched out ;
