Goleopterological Notices. 391 



2 It is difficult to draw any rigid distinction between the form of 

 tarsal vestiture of the Amphidorini and Upes, and, 



3 It does not seem proper to class together genera like Tenebrio, 

 with the tarsi very sparsely and coarsely spinose beneath ; and the 

 Upes, in which they are densely and finely pubescent. 



After a prolonged and careful study of the genera involved, I 

 have been forced to the conclusion that a purely natural tribal 

 classification, which shall include no exceptional cases, is a practical 

 impossibility, but, at the same time, the following arrangement of 

 the first few tribes of the subfamily seems, at least with the mate- 

 rial at hand, to be less objectionable in this respect than any which 

 I have been able to consult. The few known exceptions will be 

 noted below : — 



Posterior coxce transverse, other characters as stated (Class. Col. N. A. p. 372). 



Fourth joint of the maxillary palpi triangular or securiform. 

 Epipleurse attaining the sutviral angle. 



Tarsi with fine, usually silken pubescence beneath Upixi 



Tarsi spinose or setose beneath. 



Elytra widely embracing the body Blaptini 



Elytra narrowly embracing the body. 



Inflexed sides of the elytra only in part composed of the epipleurse. 

 Middle and hind coxae equally and widely separated ; elytra 



strongly inflated Pimeliini 



Middle coxre narrowly, posterior very widely separated ; elytra 

 subequal in width to the prothorax, the latter generally loosely 

 articulated and not overlapping the elytra. 



Head long, the eyes distant from the prothorax Scacrini 



Head short and transverse ; eyes near the prothorax. ...Eulabini 

 Middle and hind coxae equally and narrowly separated, the pro- 

 thorax and elytra in very close contact throughout, the base of 



the former usually overlapi^ing at the sides Pedixixi 



Inflexed sides composed entirely of the epipleurae ; posterior coxae 



generally narrowly separated Texebeiokixi 



Epipleurae not attaining the sutural angle. 



Head strongly dilated and prominent at the sides before the eyes. 



Opatkumixi 



Head not prominent at the sides ; body pubescent Amphidorini 



Fourth joint of the maxillary palpi elongate-oval, more or less finely acumi- 

 nate Leichexini 



The only exceptions which it is possible to cite at present, are the 

 genera Dendarus^ and Colpotus of the Eulabini, which have the 



i I am uncertain which of the two names Eulabis and Dendarus to apply to 

 the tribe ; they were both published in 1829.
