a Family of Coleopterous Insects. 675 



ing its form and characters with reference to any of the pre- 

 ceding genera, will be disinclined to admit that we should be 

 sacrificing the principles adopted by all modern entomologists, 

 were we to regard it as congenerous with the true Paussi. In- 

 deed I cannot but think that its peculiar form, together with the 

 structure of its palpi, clearly prove not only the correctness of 

 such a step, but also show that, if we even consider it as belong- 

 ing to the family, a very aberrant situation must be assigned 

 to it, since it appears to me clearly to point the way to some 

 other group. And I likewise feel convinced that every friend 

 of entomological science will rejoice that Dalman's " specimen 

 unicum," although " copalo inclusum," was " optim^ conserva- 

 tum et examinatu sat facile, nisi quod attinet ad pedes ante- 

 riores sub corpore retractos." 



The generic characters given above are selected from Dal- 

 man's detailed specific description, and exhibit several peculiar 

 variations in structure. The general habit or facies of colour- 

 ing of the insect, the form of the head, thorax and elytra, the 

 length and slenderness of the legs, the formation of the maxil- 

 lary, and the extreme minuteness of the labial palpi, are cha- 

 racters which evidently intimate a connexion with other families ; 

 while at the same time the antennae (although the increased size 

 of the second joint, and the rudimental articulations in the clava 

 are worthy of notice,) evidently, as Dalman has remarked, ex- 

 hibit the general " forma singularis Pauso propria."
