The spot on second vein very small and at extreme apex : usually only the 

 apical spot on second vein connected with one on third ; thorax shining 

 fulvous-testaceous; third antennal seg^ment not darkened apically; scutel- 

 lum not darkened on disk ; frous wider than long latifrons Malloch.' 



121. Costal margin hyaline from apex of first vein to the small dark spot at 



apex of second vein 122. 



Costal margin entirely, or almost entirely, dark brown from apex of first 

 vein to apex of second 126. 



122. No dark cloud over junction of second and third veins ; species yellowish 



testaceous in color, the only dark markings consisting of small dorso- 



central spots on abdomen 123. 



A dark cloud over the junction of second and third veins: species largely 

 black or fuscous ; longest hairs on arista longer than width 6f third 

 antennal segment ; male with some long fine bristles on anteroventral 

 surface of hind femur 124. 



123. Frons wider than long, entirely yellow; longest hairs on arista fully as 



long as \\idth of third antennal segment ; cell between auxiliary and 

 first veins entirely hyaline ; abdomen without dark dorsocentral spots ; 



thoracic dorsum without vittae latifrons Malloch. 



Frons longer than wide, with two pale brownish vittae; longest hairs on 

 arista about half as long as width of third antennal segment; apex of 

 cell between auxiliary and first veins infuscated ; abdomen with a black 

 dorsocentral spot on each tergite of apical half ; thorax with four or six 

 faint rufous vittae subvittata Malloch. 



124. Frons unicolorous rufous, or very faintly clouded on orbits, and slightly 



shining, the orbital stripes hardly differentiated; thorax and abdomen 



black on dorsum talamaui (de Meljere). 



Frons bicolored, not entirely shining, and with the orbital stripes conspicu- 

 ously differentiated, and paler than parts on each side of them 125. 



125. Thorax almost entirely black ; no dark cloud on second vein above inner 



cross vein ungaranensis (de Meijere). 



Thorax testaceous yellow, brownish on dorsum; a faint dark cloud on 

 second vein above inner cross vein angustata (de Meijere). 



126. A slight but distinct break in the brown costal stripe directly above the 



first brown spot on third vein beyond inner cross vein. 



strigata (de Meijere). 

 No interruption of the dark costal stripe from first vein to apex of second. 



medionotata (de Meijere). 



127. Inner cross vein not clouded, the extra dark spot on third vein proximad 



of outer cross vein, or almost immediately over it 128. 



Inner cro.ss vein distinctly clouded, the extra dark spot on third vein 

 beyond outer cross vehi 130. 



128. The extra dark spot on third vein almost directly above outer cross vein, 



and above it a spot on second vein which does not extend to apex of 



that vein flavomarginata (Kertcsz). 



The extra dark spot on third vein well in front of outer cross vein, about 

 one-third from apex of discal cell, the dark spot on second vein much 

 beyond that on third, and extending to apex of vein 120.
