TJRANOT^NIA SAPPHIRINUS 903 



Legs slender and rather long; vestiture dusky black, bronzy brown in some 

 lights; knees brilliant white scaled; apices of femora with a patch of white 

 scales. Claw formula, 0.0-0.0-0.0. 



Length : Body about 3 mm. ; wing 2.8 mm. 



Male. Proboscis straight, long, and slender, apical portion greatly swollen 

 and with many stiff setse; vestiture of dusky brown scales. Palpi very short 

 and stout, clavate, nearly hidden by the clypeus, clothed with dusky brown 

 scales. Antennae densely plumose and rather long, in consequence the whorls 

 far apart; joints subequal, cylindrical; hairs of whorls long, halfway between 

 the large whorls a whorl of very short hairs; tori rather large, dark brown. 

 Coloration as in the female. Abdomen somewhat longer than in the female, 

 subcylindrical, broadened somewhat through fifth, sixth and seventh segments; 

 lateral ciliation moderately abundant, rather coarse, long, pale, irregular. 

 Wings much narrower than those of the female ; vestiture about the same ; stems 

 of fork-cells longer, the anterior and basal cross-veins more closely approxi- 

 mated. Mid tarsi with a single, very large and broad, simple claw. Claw 

 formula, 0.0-0-0.0. 



Length : Body about 2 to 2.5 mm. ; wing 2.2 to 2.6 mm. 



Genitalia (plate 38, fig. 252) : Side-pieces very short, rounded, about twice 

 aa long as wide or less, basal lobe broad and low, clothed with many hairs; 

 clasp-filament expanded before middle, constricted just before tip, bearing a 

 small terminal articulated claw. False harpes lamellate, revolute, bearing a 

 row of teeth within; false harpagones represented by a long, stout smooth 

 process which is twice curved; unci forming a central cone with divided tip. 

 No basal appendages. 



Larva, Stage IV (see figure of entire larva, plate 83). Head elongate, 

 longer than wide, bulging at sides, front margin with a median emargination, 

 limited on each side by a sharp spinose process projecting over clypeal spines, 

 a deep notch at insertion of antennas. Antennae small, subcylindrical, stout, 

 thickened at base, spined on one side, a single small hair at basal third ; four 

 unequal terminal spines, a pedicel with one large and one small digit. Eyes 

 moderate, pointed. Both pairs of dorsal head-hairs very stout and thick, single ; 

 a pair of two-haired tufts below ; ante-antennal tuft of four hairs, remote from 

 antennae. Mental plate rounded triangular, apical tooth round, short ; six teeth 

 on each side, the last three small, merely rounded irregularities. Mandible 

 quadrangular, the area below dentition squarely exserted ; four filaments before 

 tip, two large, two smaller, with a dense group of hairs before collar; cilia at 

 edges supplanted by filaments ; dentition heavy, of two sets of teeth on a process, 

 rounded, the first longest in each group ; second group with two very large round 

 teeth before and smaller ones at base, a broad serrate filament within ; exsertions 

 with hair-tufts at tip; three long serrate filaments and a row of stout hairs 

 within. Maxilla hemispherical, divided by a suture, hairy, outer half less 

 densely so ; a group of serrate filaments at apex on suture ; two jointed filaments 

 near middle of outer half; palpus small, with six digits of different lengths. 

 Thorax subquadrate, wider than long; hairs abundant, the subdorsal tufts of 

 mesothorax and metathorax short and stellate; subdorsal prothoracic tufts 

 multiple. Abdomen moderate, anterior segments shorter; lateral tufts of first 

 two segments long, in fours, nearly obsolete on the other segments; secondary 

 hairs with two distinct subdorsal and sublateral series of stellate tufts. Tracheal 

 tubes narrow, flexuous. Air-tube slender, straight, about five times as long as 

 wide, a moderate multiple tuft near middle, beyond pecten; pecten of short 

 evenly spaced teeth, the separate teeth flat scales, deeply serrate and with base 

 widened on one side. Lateral comb of eighth segment a row of teeth on distal 

 edge of a large transverse chitinous plate; single teeth conical and spine-like.
