Some material at hand agree very closely with Champion's descrip- 

 tion. A redescription of the species follows: 



Male: Blackish. Legs, beak, and antenna blackish brown. Legs 

 inconspicuously annulate. 



Body and legs with short, appressed, scarce yellowish pilosity. 



Head sparsely but distinctly granulosc; eyes moderately large. In- 

 terantennal spine long, decurved. 



Thoracic segments sparsely but conspicuously granulate; lengths of 

 segments: 3.0, 2.8, 1.5 mm. Armature of forefemur with inner row 

 consisting of long and short spines and alternating longer fine setae, the 

 setae arising from wartlike bases. Claws of foretarsi two, the inner 

 very short and closely appressed to base of outer. First spine of fore- 

 femur at nearly twice its length from tip of trochanter. Basal half of 

 forefemur gradually thickened to first spine. 



Abdomen with bulbous swelling (fig. 46). Second and third ab- 

 dominal segments relatively short, the bulbosity thus strikingly close 

 to the thorax. Abdomen gradually widening to middle of fourth 

 segment, apical half of fourth segment forming part of bulbosity. 

 Fifth segment forming widest part of bulbosity, the margins of the 

 tergum produced as lateral carinae and over margin of segment, the 

 elevations nearer to posterior margin, gibbous above. Basal half of 

 sixth segment forming part of bulbosity, equal in length to fifth. 

 Seventh tergum bent upward, narrowed portion beginning at basal 

 two-fifths, one and two-thirds times as long as sixth, apical half trans- 

 versely corrugate, apex ending in a sharp point, slightly surpassing 

 apex of claspers. Hind margins of second to fifth sterna straight, of 

 sixth shallowly concave medianly and before lateral margin. Hind 

 margin of seventh sternum with a broad V-shaped indentation and 

 of eighth shallowly concave. Sixth sternum one and one-half times as 

 long as seventh. Seventh sternum with conspicuous lateral basal 

 depressions. Eighth sternum visible its entire width, shorter near 

 spiracle. Clasper broad to near midlength and narrower apically, 

 apical upper angle pointing cephalad. Upper lateral margin of 

 hvpopygium bisinuate; with a large apical hook standing clear of the 

 sternum, its apex hidden under elaspers (fig. 21). 



Overall body length 20.0 mm. 



The lateral aspect of the hypopygial portion of this species closely 

 resembles uncinate. In gibbiventris, the mesothorax is shorter than 

 the prothorax, the claspers are narrower apically, and the bulbous 

 swelling is strikingly close to the thorax.
