two basal parts ellipsoidal, strongly shiny, rust-yellow, somewhat darker at tips, the apical 

 parts small and knotlike, bluntly rounded; segment bearing on dorsum a weak triangular 

 piece at its base; between apical parts of genitalia are inserted two small chitinized shields; 

 on venter, between basal parts, sheath of penis is inserted. 



Female pupa.' — Body resembling that of male, but longer and somewhat stouter (length 

 10.5 mm., diameter 1.8 mm). Leg sheaths extending to just beyond midlength of abdominal 

 segment 2. Seventh abdominal segment shortened and somewhat narrowed, on dorsum 

 largely pale, with a narrow chitinized margin only on lateral parts, so that the unchitinized 

 part forms a triangle with the ape.x directed backward; on sternum this segment almost 

 completely chitinized, rust-yellow, only a small triangular area at base on either side remain- 

 ing uncolored; chitinized plate separated from plate of next segment only by an incomplete 

 segmentation, swollen, and bearing two longitudinal impressions. Eighth segment bearing 

 on its dorsal surface the dorsal valves of ovipositor, fused at their base, chitinized thruout, 

 rust-yellow in color; segment bearing on its ventral surface a depressed conical chitinized 

 plate of a rust-yellow color, and with transverse impressed wrinkles; on either side a small, 

 dark, chitinized, lower valve of ovipositor. Other characters as in male. (When the pupae 

 are placed in alcohol, the green of the metathorax and the abdomen disappears and is 

 replaced by a yellowish white color.) 



Pupae were collected in large numbers in a pine wood near Hammern 

 in Freistadt (upper Austria) in the latter days of August, 1882. The 

 pupae live in pine stumps, near the ground, where the bark has been 

 removed, more especially in situations where the wood is somewhat sappy 

 and not yet completely decayed. Those found were not deep in the wood. 

 Their preseiice was discovered by finding the teneral adults on and near 

 a stump, and many cast skins of the pupae projecting horizontally, the 

 caudal end of the body, up to the leg sheaths, adhering to the wood. No 

 emergence holes were found on the cut surface of the stump. The adults 

 at first have a very long, pale abdomen, which is of a verdigris color, 

 most intensive at the base and paler toward the tip. The pupae that 

 were found transformed as adults in from one to three days.

Geranomyia is a rather extensive genus including about eighty species, 

 which are most abundant in the tropics of America, Asia, and Australia. 

 On the African continent the genus is apparently less common. The 

 adult flies have an elongate rostrum which is used for sucking nectar
