ANALOGIES OF THE LEPTTJR1DJE. 293 



the thorax ventricose, and the elytra abruptly termi~ 

 nated by two acute spines, similar to those of Acrocina. 



2. The Callichromince, where the body and elytra 

 are narrowed from the base. 3. The Lepturince, 

 greatly resembling the last, but head narrow and por- 

 rect at the base: the thorax, also, is narrow in front, and 

 is only spined in one or two types. 4. The Necydalince. 



And, 5. The Dasycerince, where the general form is 

 not unlike that of Stenocorus ; but the elytra are not 

 spined ; the thorax and head are of equal breadth with 

 the body, and the former, in the typical genera, is con- 

 siderably lengthened ; the thighs or shanks are nearly all 

 clavate, or suddenly thickened at their outer extremity : 

 and the aspect of very many immediately reminds us of 

 the Saperda among the Lamiidce. Looking to them as 

 forming a circle, we shall at once arrange them in the 

 following series, for the purpose of determining their 

 analogies in other groups.

(262.) The only confidence we feel in this table, re- 

 sults from the analogies which appear to exist between 

 the respective groups ; and in a conviction that the two 

 series are naturally distinct. But our analysis has not 

 proceeded sufficiently far to determine the rank either 

 of the Dasycerincp or the Dorcadionlnce : we believe they 

 are representatives of each other ; and as such we have 

 .placed them, provisionally, as sub-families. This ana-
