should have been almost iucUned to regard them as ijenerically 

 removed from their quasi-(Can{inan) allies, — the scarcely expanded 

 (and only slightly suhclavaie) terminal joint of their labial palpi (I 

 believe, in both sexes) affording a marked difference from the immense 

 and largely securiform corresponding one (at any rate in the males) 

 of the normal members of that gronp ; but as such is the case, I 

 prefer treating them (at any rate for the present) as only very ano- 

 malous Tari. As regards their more evidently specific details, they 

 recede from the T. discoideus in their smaller size and darker head 

 and prothorax, the latter of which is more distinctly roughened and 

 punctured, more straightly truncated before and behind, and is much 

 more narrowed posteriorly (wdth the extreme hinder angles them- 

 selves more prominent and acute) ; in their alutaceous and more 

 shining elytra, which are shorter posteriorly (though rather more 

 produced in the centre), with their shoulders more acute, and ^dth 

 their darker portions a little different, the basal patch being more or 

 less hachwardhj -produced between the third and fourth stria, and 

 the postmedial one larger and more suffused (extending on either 

 side to the seventh stria, instead of only the sixth) ; in their darker 

 palpi and antennce; and in their rather more coarsely serrated claws.

P. apterus, niger, subnitidus ; prothorace subquadrato autice vix latiore, 

 in disco canaliculate (canalicida antice et postice abbreviata et abrupte 

 termiuata), basi utrinque foveis duabus (una sc. interna angusta longi- 

 uscula subflexuosa lineaformi, et altera breviore latiore miuus profunda) 

 impresso ; elytris (in foemiua saltem) subtilissime alutaceis, leviter sub- 

 crenulato-striatis, singido punctis duobus impresso, interstitiis planius- 

 cidis ; antennis pedibusque mfo-piceis. 



Long. coi"p. lin. 3|-4. 



P. apterous, black, and slightly shining. Prothorax subquadrate, being 

 but very little uaiTOwed behind, and with the sides only very slightly 

 roimdcd ; scarcely as broad, even anteriorly, as the elytra ; with a deep, 

 but abbre%-iated, dorsal channel down the disk, — it being suddenly 

 shortened both before and behind ; and with two fovese on either side 

 at the base, — the inner ones being rather long, deepj subfiexuose, 

 naiTOw and lineaform, and abruptly defined ; and the outer ones short, 

 very broad and shallow (forming merely a depression). Elytra with 

 their sides almost parallel, and (at any rate in the female sex, for which
