THE PHORIDAE OF FORMOSA. 
539 
shorter one just before the tip in addition to three apical spurs. Wings 
(fig. 5) yellowish hyaline, long and narrow, with piceous veins, the 
costal vein reaching to the middle and bearing rather short and closely 
placed bristles ; first vein ending a little nearer to the tip of the third 
than to the humeral cross-vein. Third vein with a few bristles at its 
base ; straight, and not swollen at apex ; fourth vein straight, except 
for a very slight curve at its base, ending much nearer to the wing 
tip than does the straight fifth vein ; sixth long, straight ; sevent obso¬ 
lete. Halteres black, with yellow T -brown pedicel. 
One male from Toyenmongai. 
As mentioned above, this is very close to the South American 
H. insperata, differing by its higher front ; straight row of middle 
frontal bristles, and higher, impunctate occipital depression. The antennæ 
and palpi are also lighter colored. The peculiar fluting of the posterior 
edges of the abdominal segments, which I have seen in no other Pho- 
rids, is reproduced in both species. 
Conicera formosensis n. sp. (Fig. 6.) 
Female. Length 1*5 mm. Black, faintly tinged with grayish, due 
to the vestiture; palpi and tarsi yellowish brown, remainder of legs 
fusco-piceous. Front broad, nearly one half wider than high, sub-opaque 
black; lower margin with a pair of small reclinate bristles; next row 
abowe with a well-separated median pair, but apparently no lateral pair, 
although the antennæ cover this spot and a pair may have been present ; 
next row above of four in a straight line, with the lateral bristle close 
to the eye margin and much farther from the median ones than these 
are from one another. Occipital row of four, its bristles longer than 
those below, which become weaker toward the lower frontal margin. 
Third antennal joint ovate, pointed, reaching but little more than halfway 
to the vertex, clothed with short, microscopic, glistening white pube¬ 
scence. Arista one half longer than the head-height; thinly pubescent 
and thickened on its basal third. Palpi brownish yellow, at tips and 
on apical half below, with fine black bristles. Postocular cilia well- 
developed below, but less so above becoming very short toward the 
vertex. Cheeks each with two downwardly directed bristles of rather 
small size. Thorax above subopaque, clothed with scattered black hairs 
and tinged with gray by a finer, glaucous pubescence. Sides of meso- 
notum with several stout bristles before each wing; one pair of dorso, 
central macrochætæ and two marginal scutellar bristles. Scutellum nearly 
semicircular, convex. Abdomen opaque black, without any bristly hairs.
