64 Psyche [April-June 



Genotype: 8. scapheus, sp. no v. 



A genus differing from all other schendylids excepting Escaryus 

 and Eucratonyx in having several coxopleural pores on each side. 

 From these genera it differs in not having the labrum free, in the 

 non-pectinate claw of the second maxillae, the absence of chitinous 

 lines from the prosternum, etc. It departs from all other known 

 schendylids in having the anterior margin of the prosternum and 

 the femuroid of prehensors armed. 



Sogolabis scapheus sp. nov. 



Pale fulvous, with the head and prehensorial segment orange. 



Head longer than wide in about ratio 13:8. Sides of head nearly 

 parallel from the oblique caudal corners forward to in front of the 

 middle, then slightly converging. Anterior margin convex, not 

 notched at middle. Posterior margin truncate. No frontal 

 suture. 



Antennae filiform, the last joint about equalling the two pre- 

 ceding taken together. 



Prebasal plate not exposed. Exposed portion of basal plate 

 short, broad. Claws of prehensors when closed surpassing the 

 head, attaining the distal end of the first article of the antennae. 

 Anterior margin of prosternum armed with two strongly chitinized 

 teeth which in the type are broader than high, rounded. Femu- 

 roid of prehensors armed toward distal end with a subconic but 

 distally rounded tooth of moderate size. Next two joints unarmed. 

 Claw armed at base wnth a larger, strongly chitinous, tooth which 

 is conical, distally acute. 



First legs a little shorter and more slender than the second, the 

 others nearly uniform in length and thickness to the penult inclu- 

 sive. 



No ventral pores detected in the type. 



Sternite of pregenital segment of moderate width, nearly equal 

 in width and length, trapeziform, the sides and posterior margin 

 straight. Each coxopleura with five siniple pores. 



Last legs longer than the penult; with few hairs; last article 

 clawless, distally rounded.
