Coleopterological Notices. 391 



2 It is difficult to draw any rig-id 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 coxoz transverse, other characters as stated (Class* Col. N. A. p. 372). 

 Fourth joint of the maxillary palpi triangular or securiform. 

 Epipleurse attaining the sutural angle. 



Tarsi with fine, usually silken pubescence beneath Upixi 



Tarsi spinose or setose beneath. 



Elytra widely embracing the body Blaptixi 



Elytra narrowly embracing the body. 



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

 Middle and hind coxse equally and widely separated ; elytra 



strongly inflated Pimei.iini 



Middle coxa? 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 Scaurixi 



Head short and transverse; eyes near the prothorax Eulabixi 



Middle and hind coxa? equally and narrowly separated, the pro- 

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



the former usually overlapping at the sides Pedimm 



Inflexed sides composed entirely of the epipleurse ; posterior coxre 



generally narrowly separated Tenebrioxixj 



Epipleura? not attaining the sutural angle. 



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



Opatku.mixi 



Head not prominent at the sides ; body pubescent Ajipiiidorixi 



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

 nate Leichexixi 



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

 genera Dendarus 1 and Colpotus of the Eulabini, which have the 



1 I am uncertain which of the two names Eulabis and Dendarus to apply t.> 

 the tribe ; they were both published in 1829.
