44 Psyche [February* 



4. Mesonotum mostly orange; a black spot on the praescutum. (Eastern 



Brazil) pulchella, sp. n. 



Mesonotum chestnut in the middle, black on the sides of the prae- 

 scutum. (Guat. — Salvador) sackeni, sp. n. 



Teucholabis pulchella sp. nov. 



Wings banded, thorax yellowish with a large black spot on the mesonotum; 

 femora brown. 



cT. Length, 8.3 mm.; wing, 7 mm. 



Fore leg, femur, 3.4 mm.; tibia, 4.1 mm.; tarsus, 4.6 mm; (alcoholic) c? • 



Head: rostrum and palpi brown, the apices of the segments of the latter very 

 narrowly paler; antennae brown. Front, vertex and occiput brown. 



Thorax: pronotum light yellow; mesonotum entirely clear light yellow, except 

 the middle of the praescutum which has a prominent rounded, transverse, brown 

 mark extending from the level of the pseudosutural fovea back to near the suture, 

 the caudal margin of the mark produced backward in two small lobes, one on either 

 side of the median line. Pleurae clear light yellow. Halteres brown, extreme base 

 of stem pale; knob less dark than the stem. Legs: coxae and trochanters light 

 yellow; femora, basal half light brown, apical half dark brownish-black; tibiae and 

 tarsi dark brownish-black. Wings: hyaline or nearly so; an indistinct brown 

 band across the wing from the base of Rs to the end of 2nd Anal; a much darker 

 brown band, broadest in front begins over the cross- vein r and extends back to Cu; 

 outer end of cell 1st M 2 margined with brown; tip of wing brown, the inner end 

 of this band distant from the outer end of cell 1st M». Venation, as figured (Fig. b.) 



Abdomen, dark brown, the genitalia swollen. Hypopygium: (See fig. 1.): 9th 

 tergite, caudal margin strongly convex; pleural pieces very stout, at the apex with 

 two short teeth; the inner margin produced caudad and entad in an obtuse tooth; 

 viewed from the ventral aspect, with a stout apical appendage (a) inserted on the 

 side of the pleura, below the apical teeth described above; it is narrowed at the 

 ends, swollen on the inner face in the middle and bears numerous hairs at its tip; 

 just entad of the base of the apical appendage is a rounded lobe (b) ; between the 

 pleurae arises what is apparently the guard of the penis, dark brown basally, appar- 

 ently less chitinized apically (c), shaped as in the figure. 



Holotype, d\ Igarape-assu, Para, Brazil; Jan. 30, 1912. (H. S. Parish, coll.) 



Type in Cornell University Museum. 



It is probable that the body-colors, described above as brown 

 are, in fresh specimens, jet black and presumably shiny. 



The species belongs to the polita group and may be separated 

 from its allies by the key under sackeni. 



Teucholabis audax sp. nov. 



Wings unhanded; body-color yellow; large, d\ wing, 9.5-10 mm. 



<f . Length, 11.3 mm.; wing, 9.7 mm. 



Fore leg, femur, 8.2 mm.; tibia, 9.6 mm.; tarsus, 8.6 mm.
