ges. Naturwiss., 1869, vol. xxxiv, p. 394), from Corvus 

 scapulatus. The species may be recognized by the broad 

 black occipital border and occipital bands, ocular and 

 frontal blotches of the head, and by the transverse ab- 

 dominal blotches of the abdomen, much narrowed in the 

 middle in the male, and divided in the female into a 

 median and two lateral parts. The female figured by me 

 measures: Body, length 1.53 mm., width .63 mm.; head, 

 length .31 mm., width .5 mm. 



Menopon decoratum n. sp. (Plate lxxii, fig. 2.) 



One male, one female, and a young specimen from a 

 White-tailed Kite, Elanusleucurus, (Palo Alto, California). 

 A finely marked species not resembling especially any

 72 mm.; pale yellowish brown, with dark rusty brown to 

 black markings; distinct transverse bars on abdominal 

 segments, the one on segment 2 especially strongly de-

Head, length .31 mm., width .66 mm.; robust, more 

 than twice as wide as long; front broad, flatly rounded, 

 with a few short weak hairs, and on the weak swelling in 

 front of the shallow ocular emargination two strong hairs, 

 of which one rises from the dorsal surface; temples ex- 

 panded, with two longish hairs and three very long ones; 

 occipital margin concave, straight in the middle, with four 

 long hairs; large black ocular fleck; an irregular black- 

 ish brown ocular blotch (on base of antennal band), the 

 two connected by a paler curving transverse band, and also 

 connected with the occipital margin by pale, broad, ill- 

 defined occipital bands, the bases of the bands being 

 blackish brown; on the forehead in front of mandibles a 

 pale, short, curving band on each side.
