race would probably persist even if the eggs were not concealed, 

 but would certainly die out if the eggs were laid where sunlight 

 could act upon them. 



TWO NEW ORIENTAL PHORID.E. 



By J. R. Malloch, 



Urbana, Illinois. 



Aphiochseta parasitica, sp. nov. 



Female: Yellow. Frons slightly darkened towards vertex; antennse, and pro- 

 boscis yellow, palpi whitish-yellow. Pleura with a small dark spot below wing base. 

 Dorsum of abdomen brown, each segment with a very narrow yellow posterior 

 marginal line. Legs yellow, mid coxae with a black spot on their posterior surface; 

 apices of hind femora and dorsal surface of hind tibise blackened. Wings clear, 

 veins brownish. Halteres yellow. (This description is drawn from alcoholic 

 specimens. Fresh or dry mounted examples will probably be darker in color.) 



Frons slightly longer than broad, the surface with numerous short hairs; post- 

 antennal bristles 4 in number, sub-equal in size; first row of bristles convex, the 

 center pair but little below the outer pair and distinctly nearer to center of frons; 

 antennas normal in size, third joint rounded; arista bare, about one-third longer 

 than length of frons, palpi projecting beyond apex of antenna, not swollen, and 

 with about 8 distinct black bristles; cheek bristled. Mesopleura bare; scuttellum 

 with 4 bristles, the basal pair slightly the weaker. Abdomen almost bare, only a 

 few very weak setulse present, the segments sub-equal in length. Legs normal; 

 fore tarsi slender; hind femora and tibiae dilated; the mid tibial setulse weak; hind 

 femora with a few weak setulae on the basal half of the ventral surface; hind tibise 

 with 10-11 setulae extending in a series from basal thhd to apex, which at no part 

 exceed in length one-half the tibial diameter. Costa to about three sevenths the 

 wing length; fringe close, the hairs not exceeding in length twice the diameter of 

 the costal vein, first costal division about 5 times the length of second; third slightly 

 shorter than second; fourth vein gently arcuated, ending distinctly in front of wing 

 tip, slightly recurved. 



Male: Similar to female in coloration. Differs in having the frons rather nar- 

 rower; the lower pair of post-antennals minute, and the upper rather close together; 

 the antennae larger, the third joint over one-third as large as the eye; the abdomen 

 tapering; the hypopygium slightly exposed, and the anal protuberance very small, 

 W'ith 2 weak apical hairs; the costa reaching to about two-fifths the wing length, the 

 second and third divisions thereof sub-equal, and the fringe more widely spaced. 



Length: 1.75-2.5 mm. 



Tyfe: From Heliothis larva, Medan, Sumatra, May, 1912. 



Allotype {Male): Same data. Paratypes: Same data. Five specimens in all.
