I have no data on this species of Quadraceps and have not col- 

 lected the Least Tern. Peters (1936) listed Degeeriella sp. from the 

 Least Tern collected in South Carolina and Louisiana which is probably 

 this species.

 Type host: Larus canus Linnaeus — Mew Gull. 

 New England host: 



Larus marinus Linnaeus — Great Black-backed Gull. 



An easily recognized species because of the contrasting patterns 

 on the body. Body white except for dark brown pleural plates and 

 their re-entrant heads; light brown transverse bands on abdominal 

 segments II-VII on female, II-VI on male. Lateral margin and a por- 

 tion of the posterior margin of the prothorax rimmed in black. Several 

 black blotches present along the lateral margins of the head. Dorsal 

 anterior plate with anterior margin lightly sclerotized.
