7 DIPTERA OF THE FAMILY PHORIDAE FROM PABAGUAY.

1 By CHARLES T. BRUES. The present short communication relating to Paraguayan Phoridae is based upon some very interesting material recently accumulated for the Hungarian National Museum by Mrs. BABARCZY and Mr. F

IEBRIG and sent to me by Dr. K

ERTÉSZ for examination. The only Phoridae hitherto credited to the fauna of Paraguay are three in number

2 and the present collection serves to add four more, three of which are undescribed while the other was previously known from Bolivia. One genus (Gymnophora) common to northern Europe and Nort America appeare in South America for the first time, represented by a species closely similar to its northern congener. Phora LATR. There is an additional Paraguayan species in the present material, very similar to Ph. parayuayaiia BRUES (Ann. Mus. Nat. Hungarici, Yol. V, 1907. p. 400) but quite distinct as can be seen from the following key which aims to distinguish as clearly as possible the species of Phora which have the fore tibiae furnished with a series of four or five small setae, and have the proboscis of the female more strongly chitinized than usual. Whether this group is really of subgeneric value, I do not feel sure, but it is very conveniently designated as Group Dorniphoui D

AHL. 1. Hind tibiae with four or five small serial bristles similar to those of the fore tibiae. _____________ .. „ _____ 2. — Hind tibiae without such a series of small bristles. _____ 3. 1 Contributions from the Entomological Laboratory of the Bussey Institution, Harvard University. No. 42. 2 Phora paraguayana BRUES, Aphiochaeta meridionalis BRUES and A. pauxilla BRUES described in volume 5 of the present journal (1907. pp. 400—403). The peculiar termitophilous fly, Termitomastus leptoproctus SILVESTRI from Argentine Republic is erroneously attributed to the Phoridae by BRETHES. (An. Mus. Nac. Buenos Aires, Vol. XVI, p. 291.) It is one of the nematocerous Diptera.
