Since Loew's memoir no addition has been made to the extra- 

 European species of lihinr/ia mentioned by him {he. cit.) : thesa 

 are lih. nasim, Say (J. Arad. PhiL iii. 94 ; CompL Wr. ii. 81 ; 

 Wiedemann, Auss. zw. Ins. ii. 115; Williston, Synopsis N. Amer. 

 Syrphidie, Bull U. S. Nat. Mus. No. 31, p. 130), from North 

 America; lih. nigra, Macq. (Dipt. Exot. i. Supph p. 133, t. 11. 

 fig. 10), from Colombia ; and Kh. la'vitjata, L\v. (Wieu. ent. 

 Monatschr. Bd. ii. p. 107), from Japan. 



Erom specimens in the Mnseum Collection I am able to state 

 that Lijcastrirluincha niiens, Biyot (Plate V. figs. 15, 16) (llev. 

 et Mag. Zool. 1859, p. 307), from the Amazons, «hich Bigot 

 afterwards (Ann. Soc. Ent. Fr. 6^ serie, t. i. 1881, p. 373) 

 thought to be a Ehinr/ia, and identical with Eh. nigra, Macq., has 

 nothing whatever to do with lihingia, but is one of the Eristaliai. 

 The genus Li/castrirhyncha is a perfectly good and very remark- 

 able one, ^^'hich is characterized by possessing the body, wings, and 

 legs of an Erisfalis and the head of a lihingia, with a some\\'hat 

 elongated epistoma. The position of the anterior cross-vein of tlie 

 wings and the thickened posterior femora are in themselves suffi- 

 cient to dispose of all doubt as to the true affinities of the genus. 



The genus Lycastris of Walker (Trans. Ent. Soc. Lond. n. ser. 

 vol. iv. p. 155, — founded for a species from India), which Bigot 

 likewise proposes {Joe. cit.) to sink in favour of lilimgia, is allied lo 

 Criorliina ! 



Brachj/opa rnfo-cyanea, Wlk. (Ent. Mag. ii. 472), from New 

 Holland, is a Oyphipelta, Bigot (liev. et Mag. Zool. 1859, p. 307), 

 and = C. coiiifroiis. Bigot, loc. cit. (= Eristalis vcsicul(iris,'E.\:\c\\ii., 

 — Wiegmann's Archiv, 1842, 272), which is the type of tlie genus. 

 Walker's species was published in 1834, and therefore liis name 

 has the priority. This species is the only one of the genus liitherto 

 described. Bigot stated that the genus is most closely allied to 

 VoluccUa, but it has been shown by von lioder (Wien. ent. Z. i. 

 61), who re-described the genus, that its proper position is nearest 

 lihhujia.
