somewhat Y form. Last ventral plate very narrow; its anterior 

 border triangular; caudal margin straight or nearly so; sides moder- 

 ately converging caudad, straight; plate 2.33+ times longer than 

 greatest width. 



Tergite of last pediferous segment with sides substraight and only 

 slightly converging caudad; caudal margin weakly convex. Plate 

 only two thirds as wide as long. Last prescutum long and rather 

 narrow. 



Coxopleurae inflated and much elongate, crowding cephalad toward 

 bases of penult legs. Densely porose with numerous small pores as 

 shown in the figures. 



Anal ' legs very much longer and more robust than the penult ; 

 proportionately slender, the articles decreasing regularly in diameter 

 from the femur distad. Articles from the prefemur to the first tarsal 

 inclusive somewhat clavately enlarging distad; second tarsal article 

 of nearly uniform diameter or a little decreasing in width distad. At 

 end of second tarsal, joint a minute, membranous but clearly sepa- 

 rated, appendage or article bearing short hairs. 



Anterior legs more robust than those of the posterior region. 



Pairs of legs 79. 



Length 52-58 mm.

Telocricus frater, sp. nov. 



Dorsum ochraceous, the head nearly of same color. Antennae and 

 legs yellow. 



Head 1.55 times longer than wide. A little widest near caudal end 

 of the frontal region, though only slightly narrowing caudad. Sides 

 straight or nearly so back to the rounded caudal corners. Anterior 

 margin substraight. Caudal margin straight. Basal plate much 

 covered by the head and the first dorsal plate, the exposed portion 

 being fully six times as wide as long. 



Antennae rather thick, a little attenuated distad; three times 

 longer than the head. Ultimate article much shorter than the two 

 preceding articles taken together, being only about three fourths as 

 long. 



Claws of prehensors stout; when closed extending widely beyond 

 front margin of the head as usual. Claw armed at base with the usual 

 stout, conical black tooth. Femuroid bearing at its distal end a 

 black tooth somewhat stouter than that of the claw, the tooth conical,
