Bruchophagus herrerae Ashmead, 1902, p. 324. 



Female: Black. Length averages 3.9 mm. (3.6-4.8). Abdomen, 

 from the side, narrowly oval or conical; lateral compression slight; 

 averaging 2.2 mm. (1.8-2.6) in length; sixth segment long, averaging 

 .78 mm. (.70-. 90) at widest point; sculpturing on lateral surface of 

 sixth tergum heavy ventrally, continues dorsally for about one-half 

 to two -thirds of surface and then fades out so that dorsal surface is 

 smooth and shiny. Valves of ovipositor usually in line with the hori- 

 zontal axis of abdomen. Ninth tergum short to moderately elongate, 

 broad and somewhat bluntly pointed; averaging .19 mm. (.12-.25) in 

 length. Liternal genitaUa with very little dorsal extension of valves 

 anteriorly; dorsal valves mediumly broad for horizontal length turning 

 dorsally with ventral valves at much less than a right angle; stylet 

 arch in a horizontal to obhque plane; whole structure averages 1.5 mm. 

 (1.4-1.8) in length and .75 mm. (.62-.87) in height; thus height is half 

 of length or length equal to about twice the height. Tegula black. 

 Propodeum with a wide, shallow concavity and a narrow and deep, to 

 wide and shallow, usually complete median furrow; furrow widest at 

 top and narrows ventrally; lateral areas with rough punctations be- 

 tween fine UTegular ridges; median carina in furrow in upper one- 

 thu'd to one-half only; lateral carinae usually discernible to base. 

 Antenna fiUform; the scape all yellow or dark brown to black except 

 yellow base; flagellum often with segments one to five longer than 

 wide, moniUform, or segments four and five may be almost square; 

 segment six separated from seven by a distinct annulation but not as 

 truncate as proximal segments; whole structure appears short and
