NEW MALLOPHAGA. 7 



Docophorus rufus n. sp. (Plate I, figs. 6 and 9). 



A dozen specimens from the Ash-throated Flycatcher, 

 Myiarchua cinerascens nuttingi (Baja California). A 

 member, probably, of the group femorati of which 007/1- 

 viunis is the chief representative. I have not found on 

 my specimens the characteristic longish hair rising 

 vertically from the dorsal surface of the anterior angles 

 of the clypeus, but the broad clypeus, signature, genital 

 blotches, and pustulated lateral abdominal blotches are 

 of the femorati type. The species differs distinctly from 

 communis in color, in the peculiar anterior convexity of 

 the clypeus, in the extent of the transverse abdominal 

 blotches, in the presence of transverse median blotches 

 on the ventral aspect of the abdomen, and in the char- 

 acter of the genital blotches. 



Description of the male. Body, length 1.56 mm., 

 width ,31 mm.; reddish brown, lighter on head and 

 thorax, because the darker lateral abdominal blotches 

 nearly cover the abdomen; broad headed; with ventral 

 median transverse blotches on abdomen. 



Head, length .5 mm., width .48 mm.; forehead broad, 

 with expanded frontal uncolored part of clypeus flatly 

 convex, willi 11 shallow, median, curving emargination; 

 no hairs on this frontal margin; sides of forehead with 

 a pair of short hairs and a shorter single one in front 

 of and near the trabecuhe; the trabecuhe very large, 

 acute; antenme when projected backward not quite 

 reaching the occipital margin; the inconspicuous, 

 slightly pendulous eyes with a hair, and two hairs on 

 the flatly convex temporal margin; occipital margin 

 nearly straight, bare; color, reddish brown; signature 

 large, broad, anterior margin almost straight, the dark, 

 sharp posterior point projecting beyond the mandibles;
