abdomen. Ilalteres dark brown. Legs: coxse and trochanters light yellow; 

 femora light yellow, the apice broadly dark brown; tibia and tarsi brownish-black. 

 Wings, subhyaUne, with a distinct dusky tinge; stigma round, brown, its posterior 

 margin not touching Ri+j. Venation: Sc rather long, that portion beyond the 

 origin of Ks slightly longer than cell 1st M:(discal); cross- vein r close to the tip of 

 Ri; space on Rj+s before r, as long as the basal deflection of Cui; cell 1st Mi very 

 elongated, narrowed anteriorly; outer deflection of M» longer than cross- vein m 

 (these two components making up the distal end of cell 1st Mj); basal deflection 

 of Cui slightly beyond the fork of M. 



Abdomen: dark brown, not at all with metallic reflexions; two basal sternitcs 

 yellowish. 



Holotype, cf, Aguna, Guatemala, Central America (Dr. G. Eiscn, coll.) 



Type in V. S. Nat. Mus. coll. (No. 15,125), 



T. fleuralis is closest to chalyheiventris Loe\v' from the i.slaiid of 

 Cuba; it differs in its lack of metallic reflexions on the head and 

 abdomen; prothorax yellow, not brownish; mesothorax with a con- 

 spicuous ])leural stripe; femora not brownish-black except at the 

 extreme tip; wdngs not pure hyaline, but distinctly suffused with 

 darker. It is even more closely akin to the specimen which Willis- 

 ton- doubtfully referred to chalyheiventris, but no mention is made, 

 in this description, of a pleural stripe. It is very probably the 

 same species; Williston's specimen was from Cucrna\aca, Morelos, 

 Mexico. 



Teucholabis parish! sp. uov. 



Wings nnbanded; color light yellow throughout; venation not like typical 

 Teucholabis. 



cf Length, 5.2 mm.; wing, 4.1 mm. 



Middle leg, femora, 2.6 mm.; tibia, 2.5 mm. 



Hind leg, " 3.4 mm.; " 3.5 mm. 



(Alcoholic) &. 



Head: rostrum very short, pale; palpi also very short, the segments subequal, 

 only about twice as long as broad, pale yellow, .\ntenn8e, 16-segmentcd, segments 

 1 and 2 short, the second only a little more globular than the third, light yellowish ; 

 the apical segments apparently paler. Front broad; broader than the diameter 

 of one eye: ommatidia of the eye large, coarse. 



Thorax: light yellow, mesonotal pra?scutum with darker, orange, stripes (pos- 

 sibly brown in dry fresh specimens); the middle stripe is dout^e, begi/is at the 

 cephalic margin of the sclerite, ends just before the suture; the laiVral sJtipes begin 

 just behind the pseudo-sutural fovea, run caudad, crossing the suture, on the 

 scutum represented by two spots on each lobe, the posterior one triangular; post-
