 zones, except where it is replaced by the subspecies perplexus in the 

 Pacific States.

Cryptiis proximus var. perplexus Cresson, 1878, Proc. Acad. Nat. Sci. Philadelphia, 

 vol. 30, p. 359; ?. Type: ?, California (Philadelphia). 



Structure as in the subspecies altonii. 



Male: Black. Facial orbit broadly, frontal orbit narrowly, small 

 spot at top of eye, usually hind orbit narrowly, center of clypeus, 

 mandible, often extreme hind corner of pronotum, more or less of tegu- 

 la, subtegular ridge, under side of front first trochanter, usually a spot 

 on apex of front coxa, and sometimes stripe on under side of middle 

 first trochanter, yellowish white; palpi brown, yellovash basally; 

 legs fulvous, the hind tibia and tarsus brownish fulvous with the tar- 

 sal segments 2-4 and usually apex of segment 1 and base of segment 5 

 whitish; wings subh3^aline. Sometimes the yellowish marldngs are a 

 little more extensive than described. 



Female: Black. Narrow front and hind orbits, sometimes center 

 of clypeus, usually more or less of mandible, and subtegular ridge, 

 yellowish; scape fulvous; palpi brownish; legs fulvous, the hind tibia 

 and tarsus a little darker, the hind tarsus usually a little paler medially ; 

 wings moderately infuscate. 



Intergrades between this subspecies and altonii are moderately 

 common where the ranges of the two are adjacent or overlap. Most 

 of the intergrading specimens are males. These have the coxae 

 fulvous, with more or less extensive fuscous areas. Female inter- 

 grades have the coxae of a rather uniform color intermediate between 

 black and fulvous.
