140 Mr. G. Lewis on 



behind the head and laterally, punctuation largest and clearest 

 near the base, the punctures along the base are evenly and 

 transversely placed, those behind the anterior angles are 

 closer and less distinct ; the elytra, punctuation most clear at 

 the base ; the pygidia are evenly and not closely punctured ; 

 the prosttrnum is rather coarsely punctured, anterior lobe 

 marginate, keel is narrow and between the strise feebly 

 canaliculate, the striaj gradually meet anteriorly, but they are 

 somewhat obscurely indicated owing to the punctuation ; the 

 mesosternum is obtusely acuminate and margined narrowly, 

 surface and that of the metasternum is clearly but not closely 

 punctured ; the metasternum is striate laterally ; the anterior 

 tibite are 6-denticulate, posterior 3-spinose, the tarsal spine 

 being bifurcate. 



The colour of this species somewhat resembles that of 

 T. puLex, Fairm., but pulex has a broad and flat prosternal 

 keel and its striaj are parallel to each other and far apart and 

 the mesosternal marginal stria is distinctly farther from the 

 edge. These characters are noticed now for the first time.

'i3^ 



Teretrius erythrceus^ sp. n. 



Cylindricus, subelongatus, niger, nitidus, supra undique punctatus ; 

 prosterno bistriato, striis subparallelis, sparse punctato ; meso- 

 sterno stria marginali postice abbreviata ; pedibus rufis, tibiis 

 anticis 7-8-denticulatis. 



L. 21 mill. 



Cylindrical, rather elongate, black and shining, evenly and 

 rather closely punctured above ; the thorax, marginal stria 

 complete, fine behind the head and sinuous at the base; the 

 elytra, suture behind the scutellar region a little elevated and 

 the humeral smooth space is also somewhat raised ; the 

 pygidia are evenly, not closely punctured ; the prosternum, 

 striae not quite parallel, but widen out gradually and slightly 

 anteriorly, surface microscopically strigose, with a few large 

 shallow round punctures ; the mesosternum somewhat acute 

 in the middle, marginal stria anteriorly complete but fine, 

 and it does not pass the coxse, so that there is a marked 

 interruption between it and the metasternal lateral stria, the 

 nieso- and metasterna are sparingly punctured and the points 

 are smaller and not circular like those of the prosternum ; 

 the legs are reddish and the anterior tibia3 are 7-8-denticulate. 

 In form this species most resembles T. latebricola, Lew., 

 but it is somewhat less narrow.
