Head roughly quadrangular, slightly longer than wide, with the 

 anterior margin truncate and the sides of the forehead somewhat in- 

 curved. Dorsal transverse suture at the level of the antennae absent. 

 Trabeculae well developed, short, not extending beyond the level of 

 the 1st antennal segment. Dorsal anterior plate well developed, 

 broadly oval, evenly rounded in front and somewhat produced poster- 

 iorly. Prothorax short, wider than long; pterothorax with lateral 

 margins divergent and posterior margin convex. Abdomen elongate; 

 tergites in both sexes extend across the segments and unite with the 

 pleurites. Parameres of male genitalia slender elongate rods which 

 turn inward in a bend and then pass straight to the distal end; penis 

 a rod-shaped structure with large telomeres on either side. 



Cvrnmingsiella ambigua (Burmeister, 1838)

 DoGophorus amphiholus Giebel, 1961. Z. ges. NatWiss., 18: 314 



(nn for D. ambiguus Burmeister, 1838).

 Doaophorus nirmoides major Waterston, 1912 {nea Kellogg, 1896). 



Ent. Mon. Mag. ,23: 62. 

 Type host: Capetta gallinaga (Linnaeus) — Common Snipe. 



This is the only species of Cuwmingsiella found in New England. 

 The genus description will serve to identify this species. I have 

 found no published records of collections of C. ambigua in the 

 United States.
