iieiv Species of Histeridse. 249 



each other, 5 apical and dimidiate, sutural ceases just beyond 

 the middle and for two thirds of its length turns slightly 

 away from the suture ; the propygidium has scattered punc- 

 tures, with the surface between them microscopically strigous 

 and finely punctulate; thepygidium is very densely and simi- 

 larly sculptured, but except at the base it is free of the larger 

 punctures, the dense strigosity gives an appearance of opacity ; 

 the prosternum, the anterior lobe is strongly punctate, with a 

 cariniform lateral stria, and the apex is obtusely produced 

 like the mesosternum of a Cetonia (fig. 3) ; the mesosternum 

 is widely arched anteriorly, with a complete marginal stria; 

 the anterior tibite are 5-dentate, apical tooth bitid.

Hister terramutus, Lew. 



Tlister philrppinensis^ Mars., superficially is very similar to 

 this species, but the sculpture of the pygidium and the 

 curious ]irolongation of the prosternal lobe will at once distin- 

 guish it. //. philippinensis usually has the fourth dorsal 

 stria complete, but Marseul's original specimen had but three, 

 and the first abdominal segment has a bowed lateral stria ; in 

 //. lerrcemotus it is oblique. It also resembles IL myrmidon, 

 Mars.

Figure 4, introduced here, will show how differently the 

 anterior lobe of this species is formed to that of the preceding 

 species.
