324 Mr. K. G. Blair— .4 Revision of 



P. inapicalis, Pic — A ^ in the Fry Collection at the 

 British ]\juseuiu (Perak, Duhertij) has the head transversely 

 impressed between the eyes, with the vertex slightly raised ; 

 the front portion of the head between the antennae is tri- 

 gibbous, the gibbosities being arranged transversely and 

 encroaching upon the transverse impression. The antennaj 

 are rather stout, the basal joint moderately incrassate, the 

 second joint sharply dentate within ; joints 3-10 subequal, 

 expanded, each with a tine branch arising out of the apex of 

 the expansion. 



P. testaceipermis. Pic, is possibly only a variety of inapicalis. 

 Pic, It is smaller and more slenderly built, with the trans- 

 verse impression of the head in the (^ less deep, but the 

 structure of the head and antennue are essentially the same 

 as in inapicalis. 



P. brevitarsis, Lew., was described upon $ specimens 

 only, but there are in the Paris Museum ^ S S 'ii>'l 1 ? 

 from near Tokio [E. Gallois, 2.2. iv.-16. v. 09, and J. Harma7id, 

 ]906j that 1 have little hesitation in referring to this species. 



The head of the ^ has a deep transverse excavation 

 between the eyes, above the base of the antennae ; this cleft 

 is nearly closed in the middle by the forward projection of 

 the vertex, itself deeply impressed. This impression forms a 

 sharp edge overhanging the transverse cleft, and dies away 

 gradually behind. The lower part of the face below the 

 cleft has two oblique pyriform impressions with their points 

 converging near the middle of the anterior edge of the cleft. 

 The first two joints of tlie antennae are incrassate and 

 shining, the rest opaque, the third strongly produced, 4-10 

 each with a long slender branch. The sculj)ture of the head 

 approaches very nearly that of P. aurita. Lew,, in which, 

 however, the vertex is not pressed forward over the trans- 

 verse excavation. In the latter species, too, the lower part of 

 the face is rough and swollen, and the oblique impressions 

 are much smaller. 



P. laticoUis, Lew. — This species also was described upon $ 

 specimens only, but a J in the Paris iMuseuin (Mt. Takao, 

 E. Gallois, IH. iv. OU) appears to be conspcx-itic with two $ $ 

 from the same locality (23. iv. 11) that I identify with 

 laticullis, Lew. The sculpture of the head is tliat of rubri- 

 collis Lew., viz., a very broad and distinct transverse de]jrcs- 

 sion occupying the greater jiart of the /"nnit of the head, 

 almost divided by a median carina arising from its anterior
