is nnich denser, loner and ])riohl falvous; pysi'liuni reddisli, bare, 

 cldsoly distinctly punctured; winos tinged vvitli fuscous vio,iace()us, 

 the stigma blackish, nervures fuscous; ))asal abscissa of ra<lius about 

 one-fourth shorter than the second. Female. Lengtli ;" mm. Saii Marcos, 

 Nicaragua (Baker). 



Lateral keels of metanotal area roundly curved, not tonching at the 

 apex, 1 ut distinctly separated, the area beiig four, not three angled, as 

 in the othi'r sjieci^^s; down its middle is a stout stra.ight keel, on the 

 sides are fiv irregular keels, the third and fourth on the outer side 

 are curved; the apical slope is smooth, shining, bare, with a few 

 minute striae around the edges. Basal half of metapleurae smooth, the 

 ajiical stoutly irregularly striated. The apex and the upper part of 

 the propleurae aciculated, the rest stoutly closely striated. Mesopleurae 

 strongly, but not closely punctured. Four anterior and apical joints 

 of posterior tarsi rufous; the hinder spurs white. 



This species should be known by the keels of the metanotal area 

 being somewhat widely separated at the apex anil by tlie side^ of 

 the metanotum being striolated.

 fringe pale golden; clypeus yellow, slightly tinged with orange; the 

 mandibles broadly reddish; paljii black tinged willi fuscous; wings 

 not very clear hyaline, the stigma and nervures black, the first abscis- 

 sa of the radius oblique, slightly but distinctly Sihorter than the second 

 the apical oblique, rounded, angled near its junction with the radius, 

 which .sJightly projects; the fourth transverse cubital nervure is 

 oblique, the lower half slightly rounded outwardly. Front and vertex 

 closely, coarsely pTTnctured, except for a small transverse space before 

 the anterior ocellus. Clypeus strongly, but not closely punctured, its 

 apex broadly rounded. Base of yironotum bordered by a sharp stout 

 keel, behind which is a ileep distinct furrow, widely crenidated; the 

 middle is strongly punctured, the apex smooth. Mesonotum strongly 

 closely punctured around the edges, the center much more sparsely 

 punctured. Scutelhim, except at the base, closely strongly punctured; 

 the post-scutellum is more closely rugose-ly punctured. The basal two 

 central areae of metanotum are wider than long, roundly broadly 

 narrowed from the outer to the inner side, but not strongly; the inne.r 

 half of the outer part is smooth, the outer stoutly closely striated; the 

 central two of the second row are almost square, the others longer than 

 wide, the apical slope is irregularly sparsely striated around the edges. 

 Propleurae coarsely reticulated at the base above, the rest almost 

 smooth. M-esopleurae strongly, but not closely punctured; the base 

 With a widely crenulated furrow. Metapleurae closely striated above, 

 the striae on the rest oblique, somewhat widely separated. Pygidium
