from the latter by its bare third vein. It is rather slender for such a 
large species. 
Phora egregia n. sp. (Fig. 3.) 
Male. Length 3—4 mm. Black, with the lower part of the pleuræ, 
antennæ, palpi, first abdominal segment and legs except posterior pair 
beyond the middle of the femora, yellow or pale testaceous. Head with 
the bristles much larger and the eyes more pubescent than usual. Front 
smooth and shining, not hairy ; fully twice as high as broad. Lowest 
pair of bristles close to the middle of the anterior margin as usual; 
next row above consisting of four in a straight line close together but 
nearly equidistant, the lateral ones a trifle closer to the eye; next row 
above forming two rows, owing to the median pair being as far above 
the lateral ones as these are above the row of four below; ocellar row 
as usual. Occipital margin strongly arcuate when seen in front view ; 
the ocelli in a broad triangle, the lateral ones equidistant from the eye 
margin and the median ocellus. Postocular cilia stout, much enlarged 
toward the upper third of the eye then small again at the vertex. 
Cheeks each with two very long macrochætæ. Antennæ brown, yellowish 
below and darkened above ; third joint long, ovate, obtuse at tip ; arista 
as long as the head height, and nearly bare. Palpi small, deep yellow, 
strongly bristly at their tips. Thorax long; mesonotum subshining, densely 
clothed with fine bristly hairs, and along its sides with very stout 
bristles beginning at the middle and becoming longer behind ; without 
dorsocentral macrochætæ, but the posterior margin of the mesonotum 
behind the roots of the wings bears four pairs of long, backwardly 
directed horizontal bristles of which the lateral ones are longest; scu- 
tellum more than half as long as broad, with four long horizontal marginal 
bristles, each as long as the width of the scutellum. Pleuræ very high, 
their upper half opaque black, the lower sclerites testaceous, except for 
a black spot at the upper anterior corner of the metathoracic one. 
Abdomen semiopaque ; black, except for the pale venter, light yellow 
first segment and whitish overhanging hypopygial piece ; second and 
fifth segments slightly elongated ; sixth more strongly so. Legs brownish 
yellow, the anterior pair paler and the posterior pair with the upper 
edge and posterior half of the femora, and the tibiæ and tarsi black. 
Anterior tibiæ with a single external bristle at the basal third and on 
apical third internally with transverse rows of fine appressed bristles ; 
middle tibiæ each with a pair of bristles externally at the basal third ; 
posterior femora broad, but not swollen ; their tibiæ with a dense mat 
of very small appressed bristles on their hind edge, externally with a
