Closely allied to the preceding species, from wliicli, however, I 

 regard it as distinct; the size is, as a rule, larger than that of P. 

 caudata^ and the form relatively more robust. The chief differ- 

 ences, however, lie in the sexual characters of the male; in P. 

 grandis the preanal fossa is rather deeper, and the blades of the 

 forceps more arcuate in form, so that the space between the 

 blades is wider than in P. caudata, in which the blades are more 

 nearly parallel; the penis in P. caudata is sharply pointed, while 

 in P. grandis it is rounded, and with a distinct notch in the apex. 

 For obvious reasons I have not been able to dissect out the 

 penis in the type-specimen of P. caudata, but I do not think I 

 am Avrong in my identification.

(J. A short, almost parallel-sided species, the smallest known 

 to me; sparingly clothed with greyish scales, setae stout, dark 

 brown. 



Head convex, rostrum rather narrow between the ridges, the 

 sides strongly dilated, mandibles lipped. Prothorax(5 x 5 mm.) 

 rounded on sides, moderately produced in front, collar-constriction 

 slight, finely and closely granulate. Elytra(ll x 7 mm.) gently 

 rounded on sides, shoulders prominent; striate, irregularly foveate, 

 interstices setigero-granulate in single series on the first, second,,- 

 fourth, and sixth; in double on the third, fifth, and seventh, the 

 granules both here and on prothorax strongly umbilicated. Fifth 

 abdominal segment widely excavate, excavation not quite 

 reaching the anterior margin, but coming close to the sides 

 anteriorly, rather shallow at the sides but deep in the middle, 

 preanal fossa being not sharply marked off; fascicles moder- 

 ately far apart(2 mm.), situated on anterior margin of excavation; 

 posterior border strongly bearded Avith a fringe of black bristles, 

 an intermediate row of red bristles situated midway between the 

 posterior row of bristles and the anterior margin; forceps short, 

 very stout at base, laminae obliquely set on inner surfaces of the 

 blades, their apices almost meeting. Dimensions : (J, 17 x 7mni.
