Dexia aiigusta {ibid. p. 314. — Brazil) is a Stonuitodexia, 

 Br. & von Berji;., near, or perliaps identical with, S. (Dexia) 

 diadema, AVicd. 



Dexia plana {ibid. p. 315. — Brazil) is a Stomatodexia, near 

 5. diadema, Wied. 



De.ria suffusa [ibid. p. 31 7. — Locality unknown) appa- 

 rently belongs to a new genus of the " Section " Pseudo- 

 de.ria, " Sub-Section " Thelaira, Br. & von Berg., near 

 Xanthodea-ia, v. d. "Wulp. This species presents a deceptive 

 resemblance to A'avt/iode.ria sericea, \Vied., from which, 

 however, it can at once be distinguished by the frontal 

 stripe being w ide and by the presence of marginal macro- 

 chaeta;on all the abdominal segments. Orbital setsein female 

 stout and conspicuous ; face and jowls narrow ; antenn?e 

 lather below level of middle of eyes ; bend of fourth vein 

 rounded. 



De,ria? albicans (Trans. Ent. Soc. Loud. iv. (1858) 

 p. 204. — R. Amazons, Brazil) belongs to the ''Section'^ 

 Sarcojihaga, Br. & von Berg., and apparently to a new 

 genus. — Aery narrow and somewhat resembling a Scato- 

 phaga in shape and general appearance; head in profile 

 square, with rather prominent front ; eyes semicircular in 

 outline; face bare; arista feathered on rather more than 

 ])asal half; abdomen, femora, and front and middle tibiae 

 clothed with short woolly hair; hind tibiffi in male shortly 

 ciliated on inner side ; first joint of front tarsi someM'hat exca- 

 vated on underside ; abdomen totally devoid of macrochsetje 

 except on hind margin of fourth segment; third vein bristly 

 lor three-fourths of the distance from the base to the small 

 transverse vein ; remaining veins bare. 



De.ria insolita (Ins. Saund. — Dipt. iv. (1852) p. 318. — 

 Brazil) may, provisionally at any rate, be referred to Hystri- 

 chodexia, von Rcider : there is a row of stout macrochaetse on 

 the hind margins of the second and third abdominal segments, 

 lait on the disc of the latter segment macrochaetae appear to 

 be wanting. 



Tachina similis (ibid. p. 269. — S. America) is a Peleteria, 

 near P. robust a, Wied. 



De.ria harpasa (List Dipt. Ins. Brit. ^Mus. iv. (1849) 

 p. 840. — N. America) = Ptilodexia tibialis, Rob.-Desv. 



DeAa cerata (ibid. p. 847. — N. America) is a Rhynchu- 

 de.ria, v. d. Wulp {Bigot, pro parte). 



Dej-ia jjristis (ibid. p. 841. — Massachusetts) belongs to 

 the genus Aporia, Macq. The type is in very poor 

 condition.
