NEW MALLUl'HAGA. lUl 



oi fidiyinosiLs, which were collected from Dloiiiedca e.ru- 

 laiis and chlororhyncha by being larger, by showing no 

 difference in the clypeal front of male and female, by 

 having no short hair in the eye, and in otlier minor 

 characters. We make a variety, therefore, for them. 



\'ar. 77ia/07' Kellogg and Chapnuin. (Plate Vll, fig. 3). 

 In tiie following table of dimensions the figures enclosed 

 in parentheses are the measurements given by Taschen- 

 berg for the type specimens. Male. Body, length 3.75 

 mm. (3.32 mm.), width .9 mm. (.58 mm.); head, length 

 1. mm. (.80 mm.), width .60 mm. (.55 mm.) Female. 

 Body, length 3.9 mm. (3.72 mm.), width .94 mm. (.06 

 mm.); head, 1.05 mm. (.9 mm.), width .7 mm. (.59 

 mm.). From these measurements the head of the vari- 

 ety is proportionately wider than in the type forms. 

 The species is recognizable by its dark color and the 

 characteristic double set of internal bands in the 

 forehead. 



Lipeurus farallonii Kellogg. (Plate VII, fig. 4). 



New Mallophiiga, I, 1896, p. lO.'l pi. v, tig. 4. 



Many specimes from two individuals of Brandt's Cor- 

 morant, F/udacroconix peaicUlatus (Bay of Monterey, 

 California). Described (as a Xirrnns) from a single 

 female from a Farallon Cormorant, Plialacrocora.i- di/o- 

 phiis cdboclliatus (Bay of Monterey, California). The 

 finding of the males of this species shows that it is a 

 Lipeurus of the group dupeati sutura distincia and allied 

 to Piaget's sefusus, snb-se(osni<, at al . taken from various 

 cormorants. The marked difference in size, outline and 

 marking of the two sexes is striking, and likely to be 

 confusing to students who may happen to meet but one 

 sex. Is it possible that Piaget's Xirmus dispar, which 

 the female of faridlonii resembles, can be the female 

 of someone of these Lipeuri of the cormorants?
