costiform, third and fifth more prominent than the rest, first 

 outturned at base to join third, obsolete posteriorly; second, 

 fourth, and sixth tending to lose their costiform character and 

 become granulate; fourth ending a little beyond middle. Sides 

 transversely rugate in two rows separated by subcostate inter- 

 stice. Metasternum shallowly impressed in middle. Fifth 

 ventral segment deeply excavate, excavation steep, not reaching 

 • anterior edge; intermediate ridges prominent, ending abruptly in 

 front of the deeply sunken preanal fossa; fascicles very small and 

 close together, situated within the excavation at the ends of the 

 intermediate ridges. Forceps moderate in length, not so long as 

 in P. miracula, outer faces rounded, inner sides concave, directly 

 facing one another, with no inclination forwards as in P. mira- 

 cula) laminse moderately large, rounded, fringed at base with 

 dark hair. Legs long, rather thin, densely clothed with black 

 setae. Dimensions : (J, 23 x 9 mm. 



^«&._Victoria(1). 



I have received from Mr. A. M. Lea a single specimen of this 

 species bearing a label " VictoriaC?), F. H. du B." Among the 

 species with armed mandibles, it is most closely allied to P. 

 miracnla Macleay,but differs in the prothoracic granules, distinct 

 without any tendency to become obsolete, the elytral sculpture 

 more regularly foveate, and the anal forceps shorter and with 

 their inner faces directly facing; the legs, notably the posterior 

 tibiae, thinner and lighter. The abdominal fascicles are rather 

 smaller and more closely set in P. approximata. From the other 

 members of the group, the position of the fascicles will separate 

 it.
