FAMIIA' CAMBALIDAE. 



Paiteya, jj^en. nov. 



Eyes fairly well de\'eloi)cd, consisting of a moderate number of 

 ocelli arranjijed in two or more rarely in three transverse series. 



Antennae short, a little clavately thickened distad. Second article 

 longest, the sixth next; the others much shorter, the third, fourth and 

 fifth not much differing in length. The four sensory cones slender and 

 moderately long. 



Gnathochilarium narrowest proximally. Promentum elongate, 

 triangular comjiletely separating the laminae linguales which are strong- 

 ly narrowed proximad. 



Body iulus-like in general form. All segments striate beneath; 

 dorsum of segments from the fourth to the antepenult, not inclusive, 

 each with a series of strongly developed keels of which the most ventrad 

 on each side is thickened and bears on the enlarged caudal portion of 

 edge the spiracle. 



Legs definitely armed with spiniscent bristles. 



First legs of male reduced; with six articles; normally armed. 



Second legs of male likewise reduced but otherwise normal in 

 structure. 



Type — Paiteya errans sp. nov. 

 Distribution — Southern California. 



Paiteya errans sp. nov. 



Brown in transverse encircling bands which, except on anterior 

 segments, alternate with ]5aler yellow bands which are broadest on dorsal 

 surface and increase in extent on posterior segments; fifteen or so of the 

 segments immediately following the fourth with an oval pale spot 

 enclosed in the dark band laterally, these spots on posterior segments 

 becoming confluent on the caudal side with the yellow of the adjacent 

 yellow stripe; first four segments usually unmarked laterally with any 

 such pale spots. A row of black spots on each side in line with the 

 spiracles and extending caudad as far as the antepenult segment, not 

 inclusive; these dark spots sharply defined excepting on the most anter- 

 ior segments where they tend to be more diffuse and commonly enclose 

 a paler area. First four segments commonly with a pale transverse 

 band on dorsum, this band narrow at mesal line and expanded laterally, 

 commonly areolated with dark. All dorsal carinac dark along their 

 edges. Anal scutum brown excepting the caudal portion. Venter, 

 legs and antennae yellow. Vertex crossed by a transverse yellow band 

 which exjDands about the black eye area on each side. Between eye 

 and antenna of each side and those of the opposite is a broad brown 

 area which is often areolated with i)ale. Head below this latter dark 

 band yellow. 



Body constricted caudad of head, most strongly so over from about 

 fourth to ninth segments.
