Rachiptera Bigot, Rev. et Mag. de Zool. 1859 (Chili) has been 
deseribed again as Perenoptera Philippi Stett. Ent. Z. 1873, p. 307, 
Tab. 2, f. 1. — I have but little doubt that the species P. angusti- 
pennis Phil. is the same as R. limbata Bigot. It produces on 
Baecharis rosmarinifolia Hook. a gall. which is deseribed and figured 
by Philippi. 
Elaphromyia Bigot. Rev. et Mag. de Zool. 1559. — E. melas 
Bigot (Port-Natal), as Mr. Bigot nimself pointed out to me, is the 
same as Trypeta ulula Loew. Berl. Ent. Z. 1861. 281. The latter 
was afterwards recognized by Loew for a Pterocalla (Loew, Monogr. 
N. Am. Dipt. III, p. 60). 
Odontomera maculipennis Maeg. D. E. Suppl. I. 211, Tab. 19, 
f. 1. (Tephritidae in Maeg. 1. e.) is the same as Üoelometopia 
ferruginea Maeg. Suppl. II. 91. Tab. 5, f. 14 (Ortalidae in Macg. 
l. e.). The former from Colombia (Colleet. Fairmaire); the latter 
from Brazil (coll. Bieot). At present, both types are in Mr. Bigot's 
collection, bearing labels in the handwriting of Macquart. Loew 
(Monogr. etc. III. 188) believes Coelom. ferruginea to be the same 
as Trypeta trimaculata Fab. The synonymy would therefore 
stand thus: 
(Gen. Coelometopia. 
trimaculata Fab. Syst. Antl. 208, 23 (Scatophaga); Wied. 
Auss. Zw. II. 480 (Trypeta): Loew, Monogr. ete. III, 188 (Üoelo- 
metopia).

Coelometopia ferruginea Maeg. Suppl. I, 91: Tab. 5, f. 14 
(Loew. 1. e.). — Patria: Brazil, Colombia (S. Amer.) 
| Senometopia decora Macq. D. E. Suppl. I. 208. Tab. 18, f. 
10 is the same as Ortalis punmetifrons Macq. Suppl. III. 61, Tab. 
7, £. 4. (Patria: Tasmania, Australia). Both types are in Mr. 
Bigot's eolleetion. The species must be referred to the genus 
Euchalcota Lw. Monogr. ete. III, 40.
