a fusion of these margins. Mandibles situated a short distance behind 

 the anterior margin. Thorax normal; mesonotum short and separated from 

 the metanotum. Prosternal plate with a median pointed process; pro- 

 sternum with 2 median setae. Third femora with a brush of normal setae 

 on the ventral surface. Second and 3rd tibiae with 3 spine-like setae 

 at their apices. Abdomen elongately oval with tergal, sternal, and 

 paratergal plates. Abdominal sternites IV-VI with brushes of normal 

 setae, those on VI may be scattered. Male genitalia with short basal

No collections of this bird nor any data or records of this species 

 of Mallophaga available. 



Eidmaniella pus tulosa (Nitzsch, 1866) 



Menopon pustulosum Nitzsch, 1866. In Giebel, Z. ges. NatWiss., 28: 



393. 

 Type host: Morus bassanus (Linnaeus) — Gannet. 



The only record found of this species in North America is by White- 

 head (1954) from Quebec. I have made several collections of the Double- 

 crested Cormorant, Phalacrocorax auritus (Lesson), and have taken 

 numerous specimens of Eidmaniella sp. from these birds. This is an 

 undescribed species of mallophagan which I am now in the process of 

 determining.

Distinguishable by its large, short, robust form. Head broader 

 than long; forehead broadly curved, temporal lobes greatly expanded and 

 angular, occiput deeply concave. Antennae small, the fossae partly

 mounted specimens. Metathorax large, lateral margins expanded pos- 

 teriorly. First pair of legs short; 2nd and 3rd pairs longer. Femur
