is entirely reddish yellow, while rufescens has the head and the 



apex of the elytra dusky or black. 

 All the species of this genus, except the second (aiontanus) , seem to be 

 fairly common, although rufescens appears rather local. Montanus is a species 

 which occurs, as its name implies, in mountainous regions, in Wales, north 

 of England, and Scotland, but it only occurs very rarely. 



Lebiides. 



Passing from the Carahides, and omitting for the present any reference to 

 the Scaritides, we commence with the first group of beetles which have not- 

 ched anterior tibiae, the Lebiides, distinguished by their truncate elytra, 

 which are generally shorter than the abdomen. The last species in this 

 family, Masoreus Wetterhalli, has the elytra so long and so slightly truncate 

 at the apex that it may cause a little trouble to its fortunate captors, but the 

 description given at the close of this article will, I think, enable them to 

 recognise it. The Lebiides (including the genus Brachinus, which is sepa- 

 rated as a distinct family by some authors) contain the following genera : — 

 Brachinus, Brypta, Polystichus. Odacantha, JEtophorus, Bemetrias, Dromius, 

 Blechrus, Metabletus, Lionychus, Lebia, Cymindis, and Masoreus. The lat- 

 ter of these is easily separable by reason of its having the anterior tibiae 

 covered with strong spines, the whole of the remaining genera having the 

 legs smooth and unarmed.
