uncommon bird in New England makes it highly unlikely that this species 

 will ever be collected here. 



Machaerilaemus oomplexus Malcomson, 1937 



Maahaerilaemus oomplexus Malcomson, 1937. Ann. Ent. Soc. Amer., 



30: 53, figs. 1-2. 

 Type host: Spizella pusilla (Wilson) — Field Sparrow. 



This species is separated from the remaining members of the genus 

 by the presence of a circular opening in the center of the gular plate 

 and by the absence of a caudally pointing process on the same plate. 



Described from 4 females and 2 males collected from the type host 

 in Pennsylvania. This is the only known collection of this species. 



Machaerilaemus maestus (Kellogg and Chapman, 1899) 



Menopon maestum Kellogg and Chapman, 1899. Occ. Pap. Calif. Acad. 



Sci. , 6: 130, pi. 9, fig. 2. 

 Type host: Zonotriohia atrioapilla (Gmelin) — Golden-crowned Sparrow. 



M. maestus has a gular plate without an opening and with more than 

 4 setae on each of its lateral margins and a metasternal plate with a 

 short seta at each posterolateral angle. 



In addition to the type host, Emerson (1947) reports this species 

 from Pipilo erythrophthalmus (Gmelin) — Rufous-sided Towhee , in Ohio, 

 New Hampshire, New York, and South Carolina; from Junoo oreganis 

 (Townsend) — Oregon Junco, in Oregon; from Pooeotes gramineus (Gmelin) — 

 Vesper Sparrow, in Michigan; from Junco hyemalis (Linn.) — Slate-colored 

 Junco, in New Hampshire; from Zonotriohia albicoZlis (Gmelin) — White- 

 throated Sparrow, in South Carolina; and from Melospiza melodia (Wilson) 

 — Song Sparrow, in New Hampshire. Since that time Machaerilaemus 

 melospizae Emerson, 1954, has been described which may now include some 

 of the above records.

I have collected a single female M. maestus from the Blue Jay, 

 Cyanocitta cristata (Linnaeus), Durham, New Hampshire, August 2, 1964. 

 This appears to be a new host record for this species of Mallophaga.
