LOBOCEKAS. 55 



the three middle joints are black, the others testaceous. The lateral furrows on vertex 

 and the transverse one behind the ocelli deep ; the lateral ones run into a dee£ 

 transverse suture over the antennae, and immediately behind a projecting ridge, which 

 has a distinct border and is emarginate in the middle. A furrow surrounds the lower 

 ocellus behind ; the space below it is blistered. Clypeus rounded, shorter than the 

 labrum, which is semicircular ; the sides of the scutellum are smooth and shining, the 

 centre somewhat blistered, slightly hollow, and there is a depression at the apex which 

 is slightly emarginated. In front the metanotum is black. The yellowish band in the 

 wings extends from the commencement of the cubital nervure to the end of the stigma. 

 The third cubital cellule is small, not half the size of the second, and not much 

 longer than the first ; the first recurrent nervure is received nearly in the middle of the 

 second cellule ; the second is nearly interstitial ; the transverse median nervure is 

 received before the middle of the cellule. Behind, the middle tibiae and tarsi are more 

 or less fuscous ; the posterior tibiae are testaceous at the base.

Hab. Guatemala, San Geronimo (Champion) ; Panama, Bugaba (Champion). 



Antennae pilose, becoming gradually thickened towards the apex, but not forming a 

 club. The first joint is longer than the second; third one half longer than the 

 fourth, which is scarcely so long as the fifth; the three last subequal; the last joint 

 projects more above than on the lower side. The eyes reach to near the base of the 

 mandibles. The clypeus is truncated at the apex ; labrum small, rounded at apex. 

 The mandible has a large apical tooth and two small blunt subapical ones ; the first at 

 the base of the apical tooth, the second close to the base of the mandible. Wings with 

 one radial cellule shortly appendiculated, and four cubital cellules; the first small, 

 the second longer than the third, and the fourth is longer than the three basal ; the 

 second receives a recurrent nervure towards the apical third, the third one in the basal 

 third. The basal nervure is joined to the cubital ; the transverse median is received 

 a little in front of the middle of the cellule ; the frontal furrows are broad and shallow 

 and bound the frontal area, which is somewhat raised ; a furrow bounds the lower 

 ocellus behind. The extreme apex of the anterior tibiae is blackish fuscous ; the apical 

 half of the middle pair and more than half of the posterior one black. The apex of 

 the middle femora before and behind and the apical half of the posterior are also black ; 

 the femora are pallid testaceous at the base.
