T. D. A. COCKERELL 33 



Carcarana, Argentina (Briiner 36). In general appearance 

 resembles Tetralonia gilva, Leytometria pereyrae, etc., but easily 

 distinguished by the palpi and other characters, including the 

 apparently normal two submarginal cells. 

 Xenoglossodes manca new species 



Male. J.eiigth, about 10 mm., anterior wing, 7 mm., flagellum very long, 

 7.3 mm. ; black, covered with pale ochraceous hair, much shorter on abdomen 

 than in A', lusor; eyes brown; facial quadrangle about square; clypeus, 

 labrum and base of mandibles creamy white; apical part of mandibles with 

 an orange patch; maxillary palpi five-jointed, second joint very long and stout, 

 third long, slender and cylindrical, fourth very short, fifth longer than fourth, 

 measurements in microns: (3.) 145, (4.) 40, (5.) 65; scape black; flagellum 

 very slender, bright fulvoferruginous beneath, dusky above; fourth antennal 

 joint hardly longer than tliird; mesothorax higlily polished, sparsely punctured; 

 tegiilac rufo testaceous; wings hyaline, nervures ferruginous; three submar- 

 ginal cells, but first transversocubital represented only by a stump on one side; 

 knees, tibiae at apex, and tarsi more or less ferruginous; legs with ochreous 

 hair; hind margins of abdominal segments hyaline, but covered with fine hair; 

 apex rufous. 



Carcarana, Argentina (Bruner 55). Resembles the last, but 

 quite distinct. 

 Xenoglossodes tnimetica (Brethes) 



Female. Length, about 11 nun., anterior wing, 9 mm.; robust, black, 

 covered with reddish-fulvous tomentum, paler on face and under side of thorax; 

 labrum black, with white hair; rpandibles with a broad orange stripe on apical 

 half, and with a small inner tooth remote from the blunt apex; clypeus black, 

 densely and coarsely rugosopunctate; flagellar joints obscurely reddish api- 

 cally; mesothorax shining and strongly punctured; tegulae rufotestaceous; 

 wings slightly dusky, nervures fuscous; small joints of tarsi ferruginous; ab- 

 domen densely covered with bright fulvous tomentum, suffusedly redder on 

 apical margins of segments; first ventral segment emarginate. The joints 

 of maxillary palpi measure in microns, (2.) 176, (3.) 160, (4.) 95, (5.) 40. 



Like Leptometria, with the same venation (see especially short broad mar- 

 ginal cell and venation of hind wings), but maxillary palpi five-jointed, first joint 

 stout, second slender, third broader, broadening apically, fourth very stout, 

 fifth minute, fourth and fifth bristly at end, no lateral hair-fringes. Omitting 

 the last joint, the palpi may be said to be davatte. 



Carcarana, Argentina (Bruner 62). This was descril)ed as a 

 Svastra, but it is probably nearer to Leptometria, notwithstanding 

 the character of the palpi. It may well go in the North American 

 genus Xenoglossodes.
