TACIIINA. 43 



Frontalia broad, black ; bristles of the front descending to one-third 

 of the face ; face slightly oblique ; epistoma not prominent ; lateralia 

 red. Antennae almost reaching the epistoma ; third joint linear, ob- 

 liquely rounded at the tip, about thrice the length of the second ; sixth 

 stout for more than three-fourths of the length, a little longer than the 

 third. Costal vein ending at some distance in front of the tip of the 

 wing ; subcostal vein ending before one-third of the length ; mediastinal 

 vein ending before half the length ; radial vein ending at about three- 

 fourths of the length ; cubital vein joining the costal near its tip ; prae- 

 brachial vein forming an obtuse angle at its flexure, very slightly in- 

 clined inward from thence to its tip ; discal transverse vein with two 

 slight curves, parted by much more than its length from the border, 

 and by its length from the flexure of the prsebrachial.

 articulo sexto ad apicem incrassato, thorace nigro-quadrivittato, alis sub-

Frontalia deep black ; bristles of the front descending to one-third 

 of the face ; face oblique ; epistoma not prominent. Antenna? reaching 

 the epistoma ; third joint linear, slightly and obliquely rounded at the 

 tip, almost thrice the length of the second ; fourth and fifth joints dis- 

 tinct ; sixth stout, bare. Costal vein ending far above the tip of the wing ; 

 subcostal vein about one-third of the length ; mediastinal vein about 

 half the length ; radial vein ending much beyond three-fourths of the 

 length ; cubital vein joining the costal near its tip ; prasbrachial vein 

 forming a very slightly obtuse angle at its flexure, which emits a very 

 short branch, near this it is slightly inclined inward, and thence straight 

 to its tip ; discal transverse vein almost straight, parted by more than 

 its length from the border, and by less than its length from the flexure 

 of the prasbrachial. Var. . Prsebrachial vein without a branch ; dis- 

 cal transverse vein with two slight curves, parted from the border by 

 much more than its own length.

Frontalia linear ; bristles of the front descending to one-sixth of the 

 face ; face vertical ; epistoma slightly prominent ; palpi tawny. An- 

 tennas nearly reaching the epistoma ; second joint ferruginous, nearly 

 twice longer than deep ; third linear, slightly truncated, a little more 

 than twice the length of the second ; fourth short ; fifth long ; sixth 

 bare stout to the tip, very much longer than the third. Costal vein
