Without dwelling upon all these resemblances., it may 

 be sufficient to remark that Lissonotus offers a striking 

 analogy to Bostrichus, in the enlargement of its thorax, 

 the comparatively diminutive size of its head, and its 

 short feet, circumstances which appear to favour our 

 idea, not only that the two groups are analogous (for that 

 is sufficiently obvious), but that they naturally stand in 

 the situation of affinity we have assigned them. A few 

 details on each of these sub-families, and of the general 

 principle which appears to enter into each, will conclude 

 our remarks on this division of the capricorns. 



(258.) The Acrocinince, although mostly large, are few 

 in number, and are chiefly, if not exclusively, confined to 

 Tropical America. The Acrocinus longimanus, Lacor- 

 daire informs us, is usually found upon the trunks of trees 

 or near them, and that it rarely occurs beneath their bark ; 

 it has an awkward gait, and drags itself along rather 

 than walks. It sometimes takes flight about nightfall, and 

 this it accomplishes heavily, but with a considerable 

 noise. It seems scarcely capable of directing its pro- 

 gress, as it frequently strikes against trees, and then falls 

 to the ground. It possesses the power, like many other 

 Coleoptera, especially Capricornes, of producing aloud and 

 sharp noise by the friction of its thorax ; and this can be
