712 Goleopterological Notices, IV. 



Tlie species in the neighborhood of morio Grav. are very much confused, and, 

 in my efforts to view a typical specimen from Europe, I have received four 

 distinct species, in one or two cases differing radically in male sexual charac- 

 ters. The following synonymy is however sufficiently evident : — 



S. morio Grav. = indistinctus and haplus Cas. 



The type of subgriseus represents a species quite different from morio, in the 

 abruptly very narrow sixth ventral segment and other characters. 



S. umbratilis Cas. =fraternus Cas. 



S. pollens Cas. = patens Cas. 



S. reconditus Cas. = propinquus Cas. This species is stouter than the 

 European tarsalis, and has the punctuation stronger and coarser ; it also 

 differs in male sexual characters. The differences become quite evident with 

 the large series of both these species which I have before me. Canadensis is 

 closely allied but has much shorter elytra. 



S. callosns Er. = varipes Cas. 



S. punctatus Er. = dilutux and ohsoletus Cas. 



S. hubbardi Cas. = simiolus Cas. 



S. lucidus Cas. = leciceps and politulus Cas.
