Mr. A. G. Butler on the Genus Phrynus. 123 



mated lunate white spots on one side, the ends of the two 

 series being united above and below so as to produce a distinct 

 fusiform marking. 



This interesting species is allied to P. cheir acanthus.

 prominent, subovate ; eyes wide apart ; lateral tubercles much 

 smaller, rounded ; eyes yellow. Abdomen black, pitchy at 

 the sides, irregularly transversely granulated. Legs pitchy, 

 becoming castaneous towards tarsi ; ligaments yellow ; femora 

 coarsely granulated, with strong, conical, terminal, internal 

 tooth ; tibias and tarsi finely granulated and pilose ; palpi dull 

 black, yellow at the joints, and with coxas and under surface 

 of terminal joint castaneous, coarsely granulated; the coxae 

 with short hairs on their opposing edges ; mandibular process 

 well developed ; trochanters with four or five short denticles 

 on antero-superior edge, otherwise exactly as in P. Batesii; 

 femoral joint semicylindrical, with ten spines on its interior 

 margins — five above (that next to the proximal end double), 

 and five below ; tibial joint similar to the femoral, with thir- 

 teen spines on its inner margins, seven above and six below, 

 the third, fourth, and fifth above considerably longer than the 

 others (4^ lines) and subparallel ; terminal joint long, shining, 

 coarsely granulated internally, quadrispinose at base, the an-
