The following three Nearctic Psammocharids have been de- 

 scribed under Aporus; since in my opinion they do not belong in 

 Aporinellus Banks, their status may be briefly discussed. 



Aporus magnus Banks, 1910,^ is based on a cT from Fedor, Lee 

 County, Texas. Mr. Banks has informed me that he has trans- 

 ferred this to Pedinaspis, and after examining the type specimen I 

 fully agree with him. The pronotum is very long, as long as the 

 mesonotum and distinctly flattened above; the posterior margin 

 of the propodeum is deeply emarginate but the lateral angles are 

 not spinose nor conical. There are three cubital cells in the fore 

 wings, all broadly open on the radial vein. Length 12 mm. 



Aporus minimus Cresson, 1872,^ was based on a cf from Texas. 

 I have not seen the type, but a cf taken by Mr. Banks at Falls 

 Church, Va., agrees perfectly with Cresson's description. It is 

 about 3 mm. long; the propodeum is very feebly emarginate 

 behind, but there are no projecting lateral edges; the pronotum is 

 convex. The venation of the fore wings is peculiar; the radial 

 cell is long and narrow; there are two cubital cells, the second of 

 which is scarcely half as long as the first, regularly trapezoidal, 

 much narrowed on both sides on the radial vein; it receives the 

 first recurrent vein near the first transverse cubital and the second 

 recurrent about its middle. If this specimen represents the true 

 Aporus minimus Cresson, the species will probably be placed in
