new Species of Histerldtev 187 



and tlic posterior edge is thickened and somewhat overhangs 

 the j)ygidiuni, the hitter punctate; the presternum is narrow 

 and bistriatc, striae j)arallel until they join in front just before 

 the suture ; the mesosternum, acumination minute, stria well- 

 marked and slightly bent in front, surface (and also that of 

 the nietasternum) punctulate ; the anterior tibiffi o-dentate. 



This is another very remarkable species, but evidently a 

 species of Pach^crcerus.

Pachi/crcerus mimic us, sp. n. 



Oblongus, parallclus, subcylindricus, rutb-brunneus, nitidus ; capite 

 excavate, stria Integra ; thorace quadrato, puuctulato, stria In- 

 tegra, ante seutellum foveolato ; clytris, striis subhumerali, 1— i 

 et suturali integris, 5 dimidiata ; prosterno bistriato, striis an- 

 ticis et posticis conjunctis.

Oblong, parallel, subcylindrical, reddish brown, shining ; 

 the head, face excavated as in the last species, surface with 

 various-sized ])unctures, not closely set, stria complete, straight 

 anteriorly, and continuing along the base of the head, clypeus 

 pointed in front ; the thorax quadrate, with an antescutellar 

 fovea, lateral stria complete and continued finely in front, 

 surface somewhat closely and a little irregularly punctured ; 

 the elytra — stri^, subhumeral external complete, internal very 

 short and basal, 1-4 and sutural complete, 5 dimidiate, the 

 sutural at the base turns away from the seutellum ; the pro- 

 pygidiura and pygidium are punctured like the thorax and 

 the latter is convex above ; the prosternum, keel narrow and 

 straight, widening out only at the base, the strise join at the 

 base and in front, at the base they widen out a little, ante- 

 riorly they run nearly parallel until they join before the 

 suture ; the mesosternum is feebly produced in front and 

 rounded oft' in the middle, sinuate on either side, the stria is 

 fine and continues round the anterior angles, and is then lost 

 in two transverse impressions which are seen on the anterior 

 edge on either side ; all the sternal plates are punctulate ; 

 the tibiae, anterior pair 4-dentate. 



Superficially this species resembles one of the cylindrical 

 Plati/somce.
