setae on each posterolateral angle of enlarged abdominal sternite II. 

 Posterior femur and abdominal sternites with or without brushes of setae 

 ventrally. Male genitalia with basal plate moderately long, continuous 

 distally with a broad, rounded lamina at base of which are affixed 

 stout, apically incurved parameres. In size and outward appearance 

 this genus is similar to Dennyus Neumann, 1906. Throughout the genus 

 there is, according to Ferris (1916), an inherent tendency to vary. 



This is one of the largest genera of the Menoponidae. It contains 

 87 described species, 14 of which have been reported from birds known 

 to occur in New England. Members of this genus are ectoparasites of 

 birds belonging to the order Passeriformes . 



Myrsidea cucullaris (Nitzsch, 1818) 



Menopon oucuZtare Nitzsch, 1818. Germar's Mag. Ent., 3: 300 {nn 



for Redi's "Pollino del Storno Bianco"). 

 Type host: Sturmus vulgaris Linnaeus — Starling. 



There is a figure of the female and a photograph of the male in 

 Clay and Hopkins (1960).

 Type host: Turdus migratorius Linnaeus — Robin. 



Similar to M. incerta (Kellogg, 1896) in having tergite I unmodi- 

 fied but it may be separated from incerta by tergites II and III which 

 are produced posteriorly. Pronotum usually with 6 long setae on the 

 posterior margin. Sternite III with 1-3 anterior median setae. Female 

 with 2 short and fine posterior setae of tergite IX. In the male the 

 tergocentral setae of VIII are long, extending beyond the end of the 

 abdomen. The distance from the base of these setae to the end of the 

 abdomen is approximately the same as the distance they extend beyond 

 the end of the abdomen.

Myrsidea scabrei Ansari, 1956b. Pakistan J. Health 5: 167, 



figs. 4a-e. 



Type host: Hylooiehla ustulata (Nuttall) — Swainson's Thrush. 



Kellogg described the type from a collection made in California. 

 Other reports of this species, all from the Hermit Thrush, are Geist 

 (1931) from Ohio; Stanford (1932) from Utah; Peters (1936) from 

 Alabama, North Carolina, and New York; and Brimley (1938) from North 

 Carolina.
