second and third cubital cellules of equal size, the legs piceous-black (with, I presume, 

 black spurs), the antennae fuscous, and the tegulee dull testaceous.

27. Pseudagenia melanocephala. (Tab. x. fig. 18, $ .) 



Ferruginea, fronte et vertice nigris ; alis lacteis, fusco-bifasciatis. £ . 

 Long. 8 millim. 



Hob. Mexico, Atoyac in Vera Cruz (H. H. Smith). 



Head broader than the thorax, finely punctured ; the top with a fine close pile ; the 

 cheeks and clypeus with long white pubescence. Eyes coarsely faceted, curved above, 

 converging beneath ; the ocelli in a curve, the hinder ones separated from the eyes by a 

 little less distance than they are from each other. Clypeus short, broadly rounded. 

 Occiput concave. Thorax finely punctured ; the pronotum short, with a gradual slope 

 from the apex, which is widely arcuate. Scutellum slightly narrowed towards the apex. 

 Median segment more strongly punctured than the mesothorax, obscurely furrowed down 

 the centre, and with a gradual rounded slope to the apex ; the curved metapleural furrow 

 moderately deep. Abdomen about as long as the head and thorax united, shining, 

 the petiolated part of the basal segment short; the apical segments bearing long 

 fulvous or pale hairs ; the ventral segments also having long pale hairs. Legs compa- 

 ratively stout, pilose ; the tarsi with a few minute spines ; the long spur of the hind 

 tibiae does not reach the middle of the metatarsus. Wings shorter than the body ; the 

 first cloud is somewhat oblique and extends along the basal nervure, the second reaches 

 from the first to the third transverse cubital nervures ; the base of the stigma is fulvous ; 

 the second cubital cellule at the top is a little longer, at the bottom shorter, than the 

 third ; the first recurrent nervure is received in the middle, the second not far from 

 the base of the cellule. The antennae are stout, involute ; the third joint distinctly 

 longer than the fourth ; the apical six joints are black. 



28. Pseudagenia tabascoensis. (Tab. X. figg. 19, <? ; 19 a, <s organ.) 



Eerruginea ; alis fere hyalinis, fusco-bifasciatis, stiginate pallide testaeeo. c? . 

 Long. 6| millim. 



Hab. Mexico, Teapa in Tabasco (H. H. Smith). 



Head closely, finely, uniformly punctured ; the face with a sparse pale pubescence. 

 Eyes curved above, distinctly converging beneath ; the ocelli forming a triangle, the 

 hinder ones separated from each other by a much less distance than they are from the 

 eyes. Clypeus short, broad; the apex almost transverse. Occiput roundly convex. 

 Antennae moderately stout; the third and fourth joints subequal ; the apical two joints 

 black. Pronotum arcuate behind, gradually narrowed towards the base. Scutellum 

 broad, not narrowed towards the apex ; the median segment with a gradual slope to 

 the apex, somewhat elongate. The thorax coarsely aciculate ; the pleurae with a
