800 DIPTERA. 
9. Pyrellia scapulata. 
Pyrellia scapulata, Bigot, Ann. Soc. Ent. Fr. 1878, p. 835’; Gigl.-Tos, Mem. R. Accad. Scienze di 
Torino, ser. 2, xlv. (sep.) p. 7’. 
Hab. Mrxico!2, Presidio (Forrer), Santiago Iscuintla in Jalisco (Schumann), Rio 
Papagaio, Rincon, Venta de Zopilote, and Tepetlapa in Guerrero, Atoyac in Vera 
Cruz, Teapa in Tabasco (H. H. Smith). 
Several specimens of both sexes. The arista is of the same yellowish-rufous colour 
as the antenne. The thoracic dorsum is densely clothed with black hairs, but is 
without dorso-central bristles. In a few female specimens the legs are reddish-brown, 
but usually they are black, with the knees (especially of the front pair) rufous. The 
blackish frontal band in the female is narrowed towards the antenne. 
3. Pyrellia ——? 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two female specimens. They agree with the females of P. scapulata, but the sub- 
humeral cicatrix and the knees are not rufous. 
GRAPHOMYIA. 
Graphomyia, Robineau-Desvoidy, Essai sur les Myodaires, p. 403 (18380). 
1. Graphomyia mexicana, (Tab. VII. fig. 17.) 
Graphomyia mexicana, Gigl.-Tos, Mem. R. Accad. Scienze di Torino, ser. 2, xlv. (sep.) p. 9’. 
Hab. Mexico}, Rincon in Guerrero 2800 feet, Teapa in Tabasco (H. H. Smith). 
One male and two female specimens. ‘This insect is nearly allied to the European 
G. maculata, L., and perhaps may prove to be no more than a local variety of it. The 
female agrees with it almost in all respects, and the male differs only in the less 
rufous coloration of the abdomen. 
MESEMBRINELLA. 
Mesembrinella, Giglio-Tos, Boll. Mus. Zool. Anat. comp. di Torino, viii. no. 147, p. 4 (1898). 
The distinctive characters between Mesembrinella and the old genus Mesembrina, 
Meig.—as they are exposed by Giglio-Tos [/. ¢., and in Mem. R. Accad. Scienze di 
Torino, ser. 2, xlv. (sep.) p. 11],—were not at first very clear tome; but a recent 
paper by Prof. Brauer (Sitz. Ber. Akad. Wiss. Wien, civ. p. 594) shows that there 
exist, especially in the bristles of the thorax, striking differences, which fully justify 
the separation. 
In the Central-American collections before me two species of the genus Mesembrinella 
are represented.
