slenderness, about eqnal in length to the combined four tergites preceding the 
genital shield.

(Cheesman), 
The nearest relative of the present fly seems to be Limnophila (Papuaphila) 
agicalis de Meijere, which differs especially in the coloration of the body and legs. 
EverHantomy1a Osten Sacken, 1859, 
ELEPHANTOMYIA (ELEPHANTOMYODES) HYALIBASIS Sp. noy. 
Thorax almost uniformly obscure brownish yellow, the mesonotum with short 
but abundant erect setae ; rostrum long, exceeding oue-half the length of the wing; 
anterior vertex very narrow; wings with a strong brownish tinge, the costal 
border narrowly dark brown, the colour continued distad nearly to the wing tip; 
cell M in preareular field clear hyaline, contrasting with the darkened costa; 
abdomen more or less bicoloured. black, with broad obseure yellow basal rings, 
only the eighth segment uniformly darkened ; hypopygium yellow. 
¢ Length, excluding rostrum, about 6 mm.; wing, 7*5 mm,; rostrum, about 
4°5 mm. 
Rostrum black, exceeding one-half the leneth of wing. Antennae black 
throughout; verticils very long. Head dark grey; anterior vertex very narrow, 
only about as wide as two rows of ommatidia, the eyes correspondingly large. 
Thorax almost uniformly obseure brownish yellow; mesonotal praeseutum 
and seutum with numerous but short, erect bristly setae, with somewhat fewer of 
these on posterior half of mediotergite. Pleura testaeeous yellow, the anterior 
pleura more darkened. Halteres with stem pale brown, knob brownish black. Legs 
with all coxae brownish yellow; trochanters yellow; a single detached leg is affixed 
to the tab and may not belong to this specimen, as the setae are differently arranged 
than in other members of the subgenus; in this leg the tibiae and tarsi are uniformly 
blackened. Wings with a strong brownish tinge, the costal border, including cells 
Cand Se, as far distad as the termination of vein R5 dark brown; very narrow to 
scarcely evident dark seams at origin of Ms, Ry 344 and over the remainder of 
cord ; cell M in preareular field clear hyaline, constrasting conspicuously with the 
darkened costal portion; veins brown. Venation: Rs relatively long, exceeding 
in length cell 2st M», square at origin; vein Re 49.4 perpendicular at origin, bent 
at virtually a right angle, thence nearly parallel to vein Fy .2, the portion of the 
cell above it uniformly darkened; cell 7s? My large, rectangular, subequal to or 
a little longer than the distal section of vein My +2; m-cw nearly its own length 
beyond the fork of M and nearly as loug as the distal section of vein Cu; cell 
2nd A narrow, more widened before midlength.
