Rhagigastetf Guer., composed of a single species from Port Jackson. Rh. unicolor. 
Telephoromyia^ Guer., composed of a Patagonian species. 
Tachypterus^ Guer., consists of a single species, T. fasciatus, from Kangaroo Island, on the 
coast of New Holland. The genus is evidently identical with Psamatha (See ante, p. 20), 
which name must accordingly sink into a synonyme. Tachypterus chalybceus pi, 
64, fig, 5), forms a second species in tho genus. 
Agriomyia^ Guer., consists of a single species, A. maculata, from New Holland.

ThynnoideSy Guer.—Three new species, T. fulvipes, Gudr.; T. rubripes, Gudr, ; and 
T. pugionatus, all from Australasia. 
DiammUy Westw., (see ante^ pi. 54, fig. 6.) In addition to D, hicolovy the true type of 
the genus, M. Guerin describes a second species, Z). ephippigevy from Kangaroo Island, 
but it is not congenerous with the former, being in fact a female of the genus Rhagi^ 
gaster. He also suggests that apteruSy Fab., also belongs to the genus. 
Anthohoscay Gudr.—A single species from Port Jackson. {Myzene AusirelasitSf 
Guer. Atlas, pi. 8, fig. 10.) 
Anodontyroy Westw.—A single species from Chili. 
Ornepeies Guer.—Also a single species from Chili. 
Elaphroptera, Gudr.—Composed of South American species. 
AmmodromuSy Gudr.—Composed of the female of South American species. 
In the Magasin de Zoologie ” for 1842, M. Guerin has made 
numerous additions to our knowledge, both of the species and 
structural characters of these insects, adding the following new 
species:— 
Rhagigaster hesmorrhoidalis (Swan River.) 
Agriomyia marginilabris, affinis, Westwoodii, abdominalis, and Spinolse, all from Australasia. 
* Nous n’avons pas fait entrer dans ce tableau les deux genres provisoires, Diamma et 
Ammodromus; ils se composent de femelles qui entreront probablement dans les genres deji 
connus, quand on les aura mieux observees, et qu’on aura surpris leur accouplement.” 
+ This species belongs to the family of the bees, and is allied to Crocisa. 
J Tho cylindric abdomen with a recurved apical spine, unites this species with the genus 
Rhagigaster of Gudr.
