Legs short nnd stout, coiicolorous with liead, witli slight anmilations at the tip 

 of the femora and tihia.\ 



The male differs from the female by being longer, the head narrower, the 

 abdomen narrower, with sides subparallel and tip broadly rounded ; the first seg- 

 ment of the abdomen is wider than the rest with sharply projecting posterior angles, 

 the metathorax with a median clear portion, abdomen being completely obscured by 

 the continuous lateral bands which on the first and second segments are ]nistulated as 

 in the female but the remainder have not more than four small pustules, the suture 

 between the eighth and ninth is clear, while the lip of the ninth is dusky with 

 numen.)us small pustules; the genital honks are very long, though not exceedingly 

 heavy, e.xtending from posterior portion of third segment to lip of abdomen. 



It measures: body, length 1.67 mm., width .52 mm., head, length .56 mm., 

 width .64 mm. 



Several males and females collected from a Red-shafted Flicker 

 {Cola/'frs cafer) shot at Lincoln, Neb., Nov. 3, 1900. This new 

 form has little resemblance to any species of this genus yet described 

 from any of the Fici. It is easily recognized by the short body and 

 wide, abruptly tapering head.
