Fring-illa arvensis Kittlitz. )

 or rather long and I'ather pointed wing, the emarginate or double- 

 rounded tail decidedlj' shorter than wing, and the tarsus not longer 

 than middle toe with claw. 



Bill moderate or rather small in size, conical, compressed, variable 

 as to relative length and depth, but depth at base always greater than 

 basal width of the mandible; culmen slightly curved, sometimes nearly 

 straight, its exposed portion more than half as long as tarsus; gon3^s 

 straight, or nearl}- so, nearlj' or quite as long as basal width of mandi- 

 ble, decidedly longer than mandibular rami; maxillary torn iuni nearlj^ 

 straight to distinctly sinuated, its basal deflection decided, but not 

 abrupt; mandibular tomium nearly straight or even obviously concave, 

 the subbasal angle prominent but obtuse, and the basal deflection very 

 decided. Nostril exposed, oval or nearly circular, with a slight postero- 

 superior operculum. Rictal bristles very indistinct. Wing moderate 

 to long (less than three and a half to four and a half times as long 

 as tarsus), rounded (eighth and seventh primaries longest, ninth not 

 longer than sixth), or pointed (ninth primary longest), the primaries 

 exceeding proximate secondaries by less than length of exposed cul- 

 men (in S. columhiana) to more than length of tarsus (^S*. chrysops,
