Head circumf asciate with an obvious semilunar chitinous ridge an- 

 terior to the mandibles. Antennae filiform and similar in the 2 

 sexes; clavi prominent and short; temporal lobes acutely angled, each 

 with 2 long setae at the posterolateral angle. Posterior margin of 

 occiput concave. Prothorax narrow. Dorsal posterior margin of the 

 pterothorax projects over the abdomen. Abdomen of both sexes broad, 

 oval; posterolateral angle of each segment with 2 prominent setae. 

 The most important generic character is the bell-shaped head, to which 

 the generic name refers. Lice of this genus are ectoparasitic on birds 

 of the order Columbiformes .

This is the only species of the genus known in North America. The 

 generic description will serve to identify this species. It has been 

 reported by Wilson (1928) from New York, Peters (1928) Ohio, Emerson 

 (1940) Oklahoma, Brimley (1942) North Carolina, Brown and Wilk (1944) 

 Alberta, and Whitehead (1954) Quebec.

Head with broad hyaline margin arising from clypeal suture; clypeal 

 and internal bands fusing at their anterior ends; clypeal signature 

 large. Dorsal antennal bands passing inwards and downwards to form a 

 narrow suture on each side of the preantennal region. Heavily sclero- 

 tized transverse antennal band across head at the level of the mandibles; 

 dorsal and ventral occipital bands present. Pterothorax short with 

 lateral margins not divergent. Abdomen with segment I small; paratergal 

 plates without elongated re-entrant heads and bearing anterior and pos- 

 terior inwardly directed processes; the posterior process continued 

 across tergal plate as a thickened bar, giving the characteristic appear-
