 barbellate bristle ; e, dorsal ovate lanceo'ate bristle. 



a strong auxiliary vein extending from upper end of recurrent vein to junc- 

 ture of costal and cubital veins ; nearly midway between the upper end of 

 recurrent vein and apex of cubital, the latter vein curves forward abruptly 

 till it touches the auxiliary vein, making two loop-like subcostal cells ; the 

 second of which is much the larger ; subcostal vein a mere point of juncture ; 

 recurrent vein strong, making a very obtuse angle with base of median vein , 

 latter strong for the first third of its length, then distinct, but delicate to 

 to margin of wing. Discal vein obsolescent before its juncture with the
