NEW MALLOPHAGA. 65 



Genus Akidoftroctits Piaget. Body slender, elongate, 

 Nirmoid in general shape; front of clypeus with a deep 

 median rectangular notch, clypeal suture not distinct; 

 antennas similar in the sexes, situated distinctly before the 

 middle of the head, short; prothorax rectangular, meso- 

 and metathorax fused, widest (except in one species) in 

 front; abdomen with broad sutures and a longitudinal 

 median uncolored line ; slightly mesad of the lateral band 

 there runs parallel with it on each side a second narrow 

 transparent lateral band ; the two last segments in both 

 sexes abruptly narrower than the seventh and conical. 

 But four species belonging to this genus have been de- 

 scribed. 



Genus Eurymetopus Taschenberg. (Plate xi.) Body 

 broad, Docofi/iorits-like ; antennas differing in the sexes ; 

 clypeus broad, truncate; anterior angles of antennary 

 fossae produced and pointed; metathorax short, broad, 

 without indication of constriction between meso- and 

 meta-segments; coxae not projecting beyond lateral mar- 

 gins of thorax; posterior segment of abdomen broadly 

 round with slight rounding emargination, deeper in fe- 

 male than in male. But three species of this genus are 

 yet known, of which one is so aberrant that it should 

 probably be made the type of a new genus. 



Genus Gon/odes Nitzsch. Body large and broad; head 

 usually with temporal margin and outer occipital margin 

 angulated; head often varying in form in the sexes; 

 antennae differing in the sexes, third segment of male 

 always with appendage, first segment enlarged and some- 

 times with appendage; prothorax usually trapeziform, 

 metathorax much larger, rounded laterally; abdomen 

 usually broadly oval, lateral band broad. Color usually 

 whitish or pale yellowish, the blotches tawny, the bands 

 dark brown to black. Found only on Gallinaceous birds.
