long black liaii-s; no distinct constnctions on the fla<j;ollnm of tlie 

 antennae. Front dull yellowish-brown; vertex dark brown; occiput 

 paler. 



Thorax: mcsonotuni dark brown, uniform, dull opaque tlirougli- 

 out; pleura3 light grayisli-brown. Ilalteres brown. Legs: coxos, 

 trochantei-s, femora, tibia; and tarsi yellowish- brown; posterior legs 

 with the apical half of tarsal segments 1, and 2, 3, and 4, white. 



Wings uniformly tinged with yellowish; veins brown. Venation: 

 Sc long, Sc, ending beyond the fork of Ej+3; cross-vein r far out toward 

 tlie tip of Ri, so tliat Rj beyond r is only about one-fiftji tlie distance 

 on R, from Scj to r; Rs gently arcuated at its origin, in a direct line 

 with Rj+5, consequently no basal deflection to R.,+5 is present ; R,+3 

 short, a httle longer than the basal deflection of Cuj; Cui + Mj shorter 

 than M3 alone; basal deflection of Cu, at the fork of M. (See fig. 1 6.) 



Abdomen: tergum dark brown; sternum yellowish; hypopygium 

 brown. 



Female. — Length, 5.9 mm. ; wing, 7 mm. Flagellum of the antennae 

 broken; vertex more grayish; oviposter veiy long and pointed; col- 

 oration and venation as in the male. 



Paratypes. — Males, specimens 1 and 3 (Surinam) (Brazil). Similar 

 to the type, but the licad darker brown with no yellowish tinge. 

 Venation of Surinam specimen: r-m at the fork of Rs; basal deflec- 

 tion of Cu, at the fork of M. Brazilian specimen: R, beyond r about 

 one-fourth of the distance on R, between Scj and r; basal deflection 

 of Cu, beyond the fork of M. Specimen 2 (Surmam) is more inter- 

 mediate between the holotype and paratyjies 1 and 3. 



Habitat. — Holotype. — Male, Bocas del Tore, Panama, September 

 28, 1903 (P. Osterhout). In U. S. National ]Museum collection (No. 

 14926). 



Allotype. — Female, Patulue, Guatemala, Central America (700 

 feet) (G. Eisen) (received Jan. 6, 1903) (U. S. National Museum col- 

 lection). Paratypes 1-2. — Two males, Surinam (IT. Polak) (U. S. 

 National Museum collection) . Paratype 3. — ilale Igarape Assil, Pard, 

 Brazil, January 29, 1912 (Parish), (Cornell University collection). 



If the specimen figured by Wiedemann ' was really a specimen of 

 his fusca, then this species is undoubtedly closely allied iofusca. It 

 is readily distinguished by its dark brown fore and middle tarsi. 



POLYMERA THORACICA, new species. 



Size, medium; flagellar segments of the antennse bi-nodosc; wing 

 with cell M present; tarsi white; thorax dark brown, pleural stripe 

 not conspicuous. 



Male. — Length, 4.8 mm.; wing, 5.3 mm.; antennae (about), 7.5 mm. 

 Rostnim and palpi brown; antennae: basal segment dark browii, 

 segment 2 and the flagellum light brown, the base and tip of the seg-
