1913] Melander — A Synopsis of the Sapromyzidae 5!) 



The species is therefore certainly to be excluded from the Sapro- 

 myzidae, and as there is no genus in the Sciomyzidse to receive it, 

 I would propose for it the new generic name Poecilomyia. 



A further characterization presents the following: 



Head in profile a little higher than broad, the upper portion spherical; perior- 

 bita less than one-fourth the width of the interfrontalia (Mittelleiste), separated from 

 it by well-marked sutures which are parallel with the eye-margin on the front, 

 but converge at the vertex to meet the sutures of the epicephalon (cerebrale) of 

 the occiput. The interfrontalia is uniformly convex, glabrous, and highly polished, 

 is darker than the silky periorbits, and is marked with a translucent median stripe 

 extending forward from the anterior Ocellus. The arms of the frontal suture (Stirn- 

 spaltenaste) continue weakly to the lower edge of the eye, but at the usual antennal 

 dark spot they send a suture across to the eye thus dividing the frontal from the 

 facial orbits (Wangendreieck). The lunula is completely covered. The face 

 (Gesichtsleiste) narrow but widening below, at its middle no wider than the sides 

 (Wangen), in profile considerably concave, with oral margin projecting. Clypeus 

 (Schlundgeriist) entirely undeveloped. Palpi linear, porrect, extending beyond 

 oral margin, hairy beneath. Cheeks (Backen) one-half the eye-height, hairy, 

 rounding into the sides of the face (ohne Vibrisseneck). Paracephala (Hinter- 

 hauptsorbiten) loosely setose; a closely setulose patch above the neck. Eyes 

 rounded, but obliquely longer than wide. First joint of antennae small, nearly 

 bare, immersed in its socket; second joint conical, with the upper inner side pro- 

 jecting most, the outer side about one-half the length of the third joint, the inner 

 side subequal to this joint, setose, except the outside, and with three long bristles 

 on the upper edge; third joint pointed, somewhat excised above, uniformly fine- 

 hairy; the dark arista rather loosely and evenly plumose above and below; the whole 

 antenna no longer than eye-breadth, with the arista shorter than the last two joints. 

 The bristles of the head are long and strong and include: a pair of diverging post- 

 verticals, a convergent inner and a divergent outer vertical, 2 reclinate fronto- 

 orbitals and a stout pair of proclinate ocellar bristles. The lesser ocellars are very 

 small. The orbital bristles arise from dark-colored papillae. The chsetotaxy of 

 the thorax is as follows: 1 humeral, posthumeral, 2 notopleural, 1 presutural, 3 

 dorsocentral, 1 pair prescutellar, 2 pair convergent scutellar, 1 supraalar, and 2 

 approximate postalar bristles; no prothoracic or pleural bristles, except a couple 

 (Vallarborsten) on the pteropleural ridge just under the calypter. Meso-, ptero-, 

 and sternopleura? with scattered fine hairs, the last witli a bristle in the angle below. 

 Calypteres pale yellow, with pale fringe. Front femora with several bristles in 

 extensor row, hind femora c? 1 biseriately spinose beneath; front and hind tibia? with 

 preapical bristle, middle tibia? with usual ending of bristles. Last two segments 

 of abdomen with long submarginal bristles; hypopygium globose. Wings reticulate 

 with alternating light and dark spots, costal margin unbroken; first vein cm ling 

 midway between tip of auxiliary vein and the anterior cross vein; veins not sinuate, 

 third and fourth veins subparallel; anal vein complete. 



Type: Saproinij'.a decora Loew.
