SOME NEW EXOTIC PHORIDÆ. 
405 
Aphiochæta Bírói n. sp. 
(Plate VIII. fig. 4.) 
Female. Length 1*25—1*5 min. Dark brownish varied with black; 
legs testaceous. The thoracic dorsum is always brown, but the front 
varies from brown to black and the abdomen is principally brown. 
Antennæ light brown ; palpi pale yellow. Front about as wide as high, 
grayish pollinose, the ocellar tubercle very distinct and the median 
impressed line deep. Four proclinate bristles close together; lower 
angles of the front each with a pair of reclinate bristles inserted rather 
far apart. Middle row curved strongly downward medially, the inner 
bristles widely separated, as far from the median line as from the eye- 
margin. Antennæ small, the arista thickly pubescent. Palpi small, weakly 
bristly below, the apical bristles stronger. Proboscis very short and 
fleshy. Cheeks with two large downwardly directed macrochætæ and 
a row of smaller ones in front. Thoracic dorsum light brown or fuscous, 
sub-shining, with a single pair of unusually weak dorsocentral macro¬ 
chætæ and four equally strong marginal scutellar bristles. The scu- 
lellum is sub-triangular, less than two times as wide as long. Abdomen 
black or piceous, the posterior margins of the segments more of less 
distinctly margined with whitish yellow. Genitalia pale. Legs short, but 
not particularly stout. Spur of middle tibia short, less than one-half 
the length of the basal joint of the tarsus. Posterior femora delicately 
but distinctly ciliated below with fine yellow hairs, their tibiæ bare, 
without any trace of setulæ, but with a fine black line along their 
hind edge; with a single short, but stout spur. Wings hyaline, the 
veins dark fuscous ; costal vein reaching considerably beyond the 
middle of the wing, its cilia exceedingly short and very thickly placed. 
Third vein forked far from the tip, the second vein meeting the costa 
two-thirds the way from the tip of the first vein to the tip of the costa. 
First vein joining the costa three-fourths as far from the humeral cross¬ 
vein as from the tip of the costa. Fourth vein curved at base and 
straight at apex ; fifth and sixth slightly bisinuate ; seventh nearly 
straight, distinct. Halteres pale. 
Three female specimens, New Guinea (Biró). Two from Simbang, 
Huon Gulf 1899 and the other from Seleo, Berlinhafen 1896. 
This species is a close relative of A. limbata Brues from India, 
but the wings are hyaline and the costal vein is longer, reaching con¬ 
siderably beyond the middle of the wing. Otherwise the two are very 
much alike.
