Alallophai!;a from Birds of Costa Rica, Central America 25 



Lipeurus longisetaceus Piag. 



Piaget, Les Pcdiculines, Sup., p. 57, pi. VI, fig. 4. 



Male. — Body, length 1.87 mm., width .33 mm.; head, length 

 .40 mm-, width .25 mm. 



Female. — Body, length 2.41 mm., width .32 mm. ; head, 

 length .56 mm., width .25 mm. 



This species, described by Piaget from specimens collected on 

 Tinamus solitarius, is distinguished by its exceedingly slender 

 form and nirmoid appearance; the head is conical with straight 

 sides and rounded front and concave occiput; the ciypeus is dis- 

 tinctly set off and pale reddish brown, with two slender fleshy 

 appendages on the dorsal surface; the antennal bands are heavy, 

 while the temples are margined with blackish ; mandibles large ; 

 whole interior of the head clear ; thorax and abdomen with heavy 

 lateral bands, interior clear. 



Two females and one male collected from Tinamus rohustus, 

 at Pozo Azul, Costa Rica, June, 1902. 



Piaget gives such a clear description and figure that a draw- 

 ing in this paper is unnecessary.
