Plate 10, Figures 65-68 



Female. — Eostrum small. Palpal femur longer than wide, only 

 slightly swollen on outer margin, with two dorsal squamiform serrate 

 setae ; apparently no dorsal genual seta ; palpal claw short, broad, with 

 teeth along entire margin; outer comb strong, with few teeth; inner 

 comb much weaker and with fine teeth ; apparently only one normal 

 sicklelike seta, the other being mildly clavate ; sensory rod short and 

 clavate. Rostrum broad, with M-like peritreme composed of narrow 

 segments ; at posterior ends of peritreme a pair of tympanlike organs of 

 unknown function. Body covered by shields ; dorsal body setae large, 

 squamiform, serrate ; four pairs of marginal setae and three pairs of 

 dorsosubmedian setae on anterior shield. Single pair of eyes present. 

 Posterior shield with six pairs of marginal setae and two pairs of 

 dorsosubmedian setae. On each side of body, apparently just beneath 

 skin is a long reticulated area as figured. A single pair of squami- 

 form serrate anal setae; other anal and genital setae simple. Legs 

 short ; leg I about 200]^ long, leg IV about 266/a long. Tarsus I, 87/a 

 long ; tibia I, 30/i long. Tarsus I with a short rodlike sensory seta and 

 a long broadly lanceolate serrate guard seta ; ventral tarsal seta serrate. 

 Tibia I with a small rodlike sensory seta, a simple ventral seta, and four 

 long, broadly lanceolate serrate setae. Length of body 366/a, including 

 rostrum 446/x ; width 266)li. 



Type hahitat. — Among eggs of termites. 



Type locality. — Panama. 



T'y^e.— U.S.N.M. No. 1766. 



The above description is based on a single mite, the type taken from 

 among eggs of termites in Panama, 1923. 



The palpal claw and dorsal reticulations are distinctive of this 

 species.
