ORTHOPODOMYIA 877 



pagones with a slender, long, columnar base, pilose, flexuous, bearing an ar- 

 ticulated terminal filament of about the same width as the stem. Unci con- 

 tiguous, revolute, forming a large basal cylinder. 



Larva, Stage IV (plate 126, fig. 438). Head rounded, widest through eyes; 

 antennae rather small, slender, smooth, a single hair near middle ; both pairs of 

 dorsal head-hairs in twos, the lower pair situated rather low down on face ; ante- 

 antennal tufts of three hairs, small. Skin of body coarsely and densely hairy. 

 Lateral comb of eighth segment of eight scales in a straight row attached to a 

 small chitinous plate, each scale with broad body and long sharp tip, smooth, 

 without lateral fringes. Air-tube stout, about two and a half times as long as 

 wide, tapered outwardly ; pecten of about fifteen evenly spaced short teeth and 

 reaching about to middle of tube, followed by a two-haired tuft. Anal seg- 

 ment longer than Avide, with a dorsal plate, notched at the sides, with a few long 

 spines along its posterior border ; dorsal tuft a long hair and tuft on each side ; 

 tufts of posterior angles six-haired and very long ; ventral brush long but sparse 

 with tufts preceding the barred area for a short distance; a small triangular 

 plate on either side of barred area; anal gills not as long as segment, stout, but 

 sharply pointed, equal. 



The larvae live in water in tree-holes and probably also in bamboo, as Mr. 

 Jennings captured adults in a bamboo woods. 



Tropical America, less distributed towards the North than the other species 

 of the genus. 



Tabernilla, Canal Zone, Panama, May 13, 1908 (A. H. Jennings) ; Caldera 

 Island, Porto Bello Bay, Panama (A. H. Jennings) ; St. Anns, Trinidad (F. 

 W. Urich). Reported also from State of Sao Paulo (Lutz) and Juiz de Fora 

 and Oliveira, State of Minas Geraes, Brazil (Peryassii). 



Coquillett placed Hcemagogus capricornii in his genus Cacomyia and the 

 short palpi of the male caused him to confuse it with Hcemagogus albomaculatus, 

 a species which has simple claws in the female. Theobald followed Coquillett 

 and placed albomaculatus in Cacomyia, but his statement about the venation, 

 taken from Coquillett, applies to the present species. Neither author mentions 

 the structure of the female claws in Cacomyia. Theobald's repetition of Co- 

 quillett's reference of albomaculatus to Cacomyia in the fourth volume of his 

 work is doubtless due to the haste of compilation.
