ridges somewhat flattened, the grooves not deep; mentum dentate 

 anteriorly. Prothorax (7 x 7 mm.) widely rounded on sides, 

 anteriorly produced to a moderate extent; finely and closely 

 granulate. Elytra(15 x 9 mm.) not much wider than prothorax^ 

 feebly rounded on sides, humeral angles thickened but not pro- 

 minent; striie transversely crenulate, hardly definitely foveate, 

 interstices finely and closely setigero-granulate; the first, third, 

 fifth, and seventh in double, the others in single series (in some 

 specimens all the interstices are granulate in double series). 

 Metasternum concave, anteriorly raised to level of middle coxae. 

 Anal excavation deep, the sides vertical, preanal fossa deep and 

 hidden; fascicles moderately far apart(2 mm.), situated on the 

 edge of the excavation. Forceps rather short, slender towards 

 apex; laminae long, straight, broad at base and tapering towards 

 apices, which are rounded and do not overlap. Dimensions : 

 (J, 22x9; O, 22x9-5 mm.

I have examined the types of P. crenata, P. Helyi, and P. 

 Howitti, as well as the one Macleay doubtfully referred to P. 

 mirabunda, and cannot distinguish them from the Tasmanian 

 species, P. imijressa^ which can be confidently identified from tlie 

 description and figure. The continental specimens differ slightly 

 in being, as a rule, smaller and narrower; but in all other par- 

 ticulars, and in the arrangement of the sexual organs of the male, 

 they are identical.

 Cure. vii. (1), p. 52; Boisd., Yoy. Astrolabe, ii., p. 377; Macleay, 

 loc. cit., p. 207. 



I am quite unable to identify this species from description, the 

 species being originally described from a female. Bohemann 

 described the male, but his description is so short as to be worth- 

 less. The species identified doubtfully by Macleay as P. mira- 

 bunda is the same as P. impressa Boisd.
