* 11. Pseudagenia gentilis. (Tab. X. fig. 10, head.) 



Mgra, dense argenteo-pilosa, femoribus posterioribus rufis, geniculis nigris ; alis fere hyalinis. $ . 

 Long. 9 millim. 



Hab. Panama, Bugaba 800 to 1500 feet {Champion). 



Eyes distinctly converging at the bottom, elbowed at the top. Hinder ocelli sepa- 

 rated from the eyes by a distinctly greater distance than they are from each other. 

 Clypeus elongate, convex, the apex somewhat sharply rounded. Head rather short, 

 compared to the breadth, the occiput transverse, the sides rounded, not much 

 developed behind the eyes; finely and closely punctured; covered with long silvery 

 pubescence, more sparsely so on the top. Prothorax short, the sides rounded, narrowed 

 towards the head. Median segment short, gradually rounded, transversely striated ; a 

 smooth, shining, finely transversely striolated, fulvous band at its base. The thorax 

 finely and closely punctured; covered with long whitish hairs, which are especially 

 long on the base and apex. Abdomen short, shining, impunctate ; the petiole with a 

 distinct neck at the base, from which it becomes gradually dilated to the apex ; the 

 apical segment shining, bearing some scattered punctures, the apex testaceous, broadly 

 rounded. Antennae stout, moderately long, covered with a close microscopic pile ; the 

 apical joints brownish beneath. Wings : second and third cubital cellules at the top 

 and bottom subequal ; the first and third transverse cubital cellules obliquely curved, 

 the second straight; the first recurrent nervure received slightly before the middle, 

 the second close to the basal fourth. Legs pruinose ; the long spur of the hinder tibiae 

 not quite reaching the middle of the metatarsus.

Nigra, nitida, mandibulis, antennis pedibusque anticis rufis ; alis hyalinis, fuseo-bifasciatis. $ . 

 Long. 7 millim. 



Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 



Eyes a little converging above and beneath. Ocelli forming a triangle, the hinder 

 ones separated from the eyes by nearly the same distance they are from each other. 

 Clypeus broadly convex, broadly rounded at the middle. Occiput slightly concave. 

 Head not much developed behind the eyes ; closely punctured, densely covered with 

 a whitish pile, and with a few longish hairs on the top ; its black colour has coppery 

 tints. Antennae short, stout ; the third joint fully one quarter longer than the fourth ; 

 the first joint not much shorter than the fourth. Prothorax as long as the head, 

 the sides broadly rounded, sparsely punctured, densely covered with a fulvous pubes- 

 cence; mesothorax shining, aciculate, the sides finely punctured. Median segment 

 very finely punctured, broadly rounded, the apex with two large spots of dull fulvous 

 pubescence; the transverse furrow in the mesopleurse placed below the middle. 

 Abdomen shining, subpetiolate, shorter than the thorax, sparsely pruinose, the apical
