two species, and the third submarginal cell differently shaped. From 

 manrns it differs by having the tarsal claws toothed, instead of cleft. Its 

 position is between athiops and maurus. 



PO.MPILUS POSTERUS. 



<j? . — Anterior margin of clypeus very slightly incurved; frontal 

 impression distinct; posterior margin of prothorax bowed ; metathorax 

 not impressed above ; tibiae and tarsi very strongly spinose, the longest of 

 those on the fore tarsi almost equalling the first joint of that tarsus in 

 length ; tarsal claws cleft ; longest spur of hind tibiae much more than 

 two-thirds as long as the first joint of hind tarsi ; wings hyaline, the 

 apical margin broadly fuscous, nervures black ; third submarginal cell 

 narrowed about one half at the top. the second recurrent nervure 

 received by it a little beyond the middle. Black : head, thorax, legs and 

 first abdominal segment clothed with silvery pile which has somewhat the 

 appearance of verdigris ; hind femora and tibia; (the spurs excepted) 

 rufous . posterior margin of prothorax narrowly whitish ; head with rather 

 sparse, pale hair. Length, 7 mm. 



o*. — More slender than the female, antennse shorter and stouter; the 

 tibial spurs, transverse band at base of third dorsal segment, and spot at 

 apex of abdomen above, white. Length, 7 mm. 



Camden County, N. J. (July) ; So. Florida (Chas. Robertson). Allied 

 to biguttatus, from which it differs in the colour of the hind legs, the 

 stronger armature of the legs and the greater length of the hind tibial 

 spur. 



Planiceps calcaratus. 



$ . — Anterior margin of clypeus rounded ; front strongly impressed on 

 lower portion ; anterior ocelli deeply pitted ; antenna? reaching much 

 beyond the tegulae, the flagellum slightly tapering to the apex ; hind 

 margin of prothorax formed into a very slight angle medially ; metathorax 

 above with exceedingly fine punctures, with longitudinal, medial, im- 

 pressed line ; tibiae with distinct, though not strong, spines, the tarsi 

 scarcely or not at all spined ; longest spur of hind tibiae as long as the first 

 joint of hind tarsi ; wings sub-hyaline, iridescent, nervures fuscous, second 

 recurrent nervure uniting with the second transverse cubital vein ; black ;
