Head elongate with V-shaped ocular bands ; temples with 1 long 

 seta and 1 short bristle on each side. Prothorax small, angles rounded; 

 heavily bordered laterally with blackish brown extending around the 

 posterior border. Pterothorax much wider than prothorax. Abdomen with 

 sides of posterior half nearly parallel to segment VIII. Material from 

 this bird appears to be quite scarce. Carriker's (1902) published 

 record of a collection of 1 female and 1 immature female from Colorado 

 is the only record from the United States.

Bruelia interposita (Kellogg, 1899) 



Nirmus interpositus Kellogg, 1899. Occ. Pap. Calif. Acad. Sci., 6: 



23, pi. 2, fig. 7. 

 Type host: Dendroica petechia (Linnaeus) — Yellow Warbler. 



Lateral margins of head weakly convex: trabeculae extend to the 

 1st antennal segment and are uncolored. Temples with a single long 

 seta; occipital margin bare, very flatly convex; forehead and temporal 

 margins narrowly bordered with dark brown. Prothorax short and wide 

 with 1 long seta in each posterolateral angle. Pterothorax short, 

 lateral margins dark brown; 6 or 7 long setae on the posterodorsal 

 margin on either side of the midline. Abdomen narrow with rather broad 

 dark brown lateral bands. 



According to Carriker (1957) this specimen was collected in Panama. 

 I have found no records of its collection in the United States and have 

 not collected the Yellow Warbler during the course of this study.

A large species, the female measuring 1.82 mm in length. Pre-

 plate, then gradually narrows to a very constricted opening into the 

 long narrow buccal cavity; gular plate extends beyond occipital margin. 

 Pterothorax with straight sides, diverging; thoracic carinae deeply 

 colored. Abdomen with narrow pleurites.
