110 Mr. David Sharp on the 



Head densely but indistinctly punctured, opaque ; the vertex 

 bifoveolate, and the front part also foveolate. Thorax 

 shorter than that of T. carinatus, not so long as broad, 

 the sides rounded in front and narrowed behind, without 

 distinct margin : it is quite dull, its scidpture being similar 

 to that of the head. Elytra rather longer, and much 

 broader than the thorax, finely and obscurely punctured, 

 rather shining, with a fine sutural stria and a discoidal 

 plica (as in T. carinatus). Hind body finely and sparingly 

 punctured, formed as in T. carinatus; the dorsal segments, 

 however, without any central line, but the first and second 

 segments with an elevated line half-way between the middle 

 and the lateral margin. The front tibia? much curved in- 

 Avards. 



Maiyasama, Hiogo ; a single specimen. 



The affinities of this insect with T. carinatus are very 

 marked. It possesses, however, some evident distinc- 

 tions, which at the same time are not of such a nature 

 as have, as yet, been considered of generic importance in 

 the Pselaphidre. The most important of these appears to 

 be the structure of the 3rd joint of the maxillary palpi, 

 which is broader and shorter than in T. carinatus, and 

 angulated externally. These organs, in fact, depart less 

 Avidely from the Ctenistes structure than do those of Tmesi- 

 phorus carinatus. The Ctenistes intef/ricoUis of Faivmaire 

 appears to supply a connection between the ordinary species 

 of Ctenistes and Tmesipliorus. While, again, I possess a 

 Pselaphid from Algeria (sent in error by Olces as the C. 

 integricollis, Fairm.), which in the structure of its palpi 

 appears intermediate between T. carinatus and speratus; 

 but from other differences this Algerian insect Avill neces- 

 sitate the establishment of a ncAv genus for its reception.
