originating near the middle of the stigma ; the first abscissa 

 of the radius short, scarcely more than half as long as the 

 breadth of the stigma; an oblique vein from the apex of 

 the stigma meeting the radius and closing the radial cell, the 

 radius not continued beyond this vein, the space between the 

 transverse cubital nervure and the oblique vein a little more 

 than twice as long as the first abscissa of the radius. First 

 cubital cell receiving the only recurrent nervure well before 

 the apex ; second cubital cell very small, with a short petiole, 

 triangular, the cubital margin a little longer than the first 

 abscissa of the radius. Median cell longer than the sub- 

 median. 



Protostif/mus championi, sp. n. 



<3 . Niger ; mandibulis, scapo, tibiis anticis, tarsisque pallide flavis ; 



flagello, tibiisque intermediis posticisque basi brunneo-flavis ; 



alis hyalinis, iridesceirtibus, venis pallidis, stigmate fusco- 



ferrugineo. 

 Long. 2*7 mm. 



<$ . Clypeus subcarinate longitudinally, triangularly pro- 

 duced and almost pointed at the apex. First joint of 

 flagellum longer than the second and third combined ; joints 

 2-5 broader than long, thence gradually lengthening and 

 becoming thicker to the apex. Front flat, obliquely sloped 

 from a little below the anterior ocellus ; posterior ocelli 



Protostigmiis championi, sp. n. 



nearer to the hind margin of the head than to each other, but 

 nearer to each other than to the eyes. Head, thorax, and 

 abdomen smooth and shining; median segment opaque, very 

 finely granulate, subcarinate longitudinally in the middle, 

 much broader than long, narrowed to the apex, the sides and 

 the apical slope almost smooth, shining, the latter with a 

 median sulcus.

This genus is very distinct in the shortened radial cell and 

 petiolated second cubital cell from Stigmus and other related 

 genera, but is to be placed in the same subfamily. Except 

 for the neuration it is very near Ammoplanus.
