152 THE CANADIAN ENTOMOLOGIST. 



Calliphora rufipes Mcq., 1843, Dipt. Kxot. II (3), 28C, Suppl. 

 II, 00, Java and Tasmania, also appears to belong here, but I 

 have no specimens and can only judge by comparing the descrip- 

 tion with material of Oceania, to which it seems extremely close. 

 Brauer (Sitz. Ak. Wiss. CYHI, 526) says that it equals Miisca 

 stygia F. {villosa R. D.), but this seems doubtful since Macquart 

 sa>s "caerulea * * * abdomen bleu." It is also rather too small 

 (0 mm.). 



Tricyclopsis, new genus. 



Genotype, Rhynchomyia diibia Mcq., 1855, Dipt. Exot. Su[)pl. 

 \', 129-30, Adelaide. Brauer, Sitz. Ak. Wiss. CVIII, 514. 



Near Tricydea W'ulp, l)ut the third vein is bare. Facialia 

 ciliate to above middle of face. Facial carina absent. Arista long- 

 plumose above and below. Parafacials with short bristly hairs. 

 Third antennal joint three or four times as long as second. Palpi 

 clubshaped. Kpistoma strongh' produced. Antennae two-thirds 

 as long as face. 



Gerotachina, new genus. 



Genotype, Tachina obtusa Walker, 1850, Dipt. Saund., 274-5, 

 New South Wales. Austen, Ann. Mag. N. H. ser. 7, XIX, 330-1 

 (Syn. Echinomyia stolida Wlk., 1858, Trans. Ent. Soc. London, 

 n. s. 1\'. 195-0, male). 



DitYcrs from Microtropesa Mcq. as follows: Third antennal 

 joint of female distinctly shorter than the second; that of male 

 not longer than the second, or but slightly longer; in both sexes 

 the third joint is convex on upper border. Arista short and stout. 

 Row of six to eight small admedian spinelike macrochietie on hind 

 margin of second abdominal segment. Agrees with Microtropesa 

 in air other characters given by Walker and Austen. 



Tasmaniomyia, new genus. 



Genotype, Masicera viridiventris (1st) Mcq., 1847, Dipt. 

 Exot. Suppl. II, 84-5, Tasmania. Brauer, Sitz. Ak. Wiss. CVI, 

 330-7. (Syn. Masicera viridiventris 2d Mcq., 1851, Dipt. Exot. 

 Suppl. IV (2), 163-4, female, locality Egypt in error).
