* of new Exotic Longicorn Beetles. 365 



near the middle of the elytra coalesce and form a waved fascia ; 

 two others, on the disc beyond the middle, also unite so as to 

 form an oblique bipartite patch ; some of these spots extend across 

 the inflexed lateral margin of the elytra. The under surface of 

 the body is black and glossy ; the sides of the pro- meso- and 

 meta-sterna and of the abdominal segments marked with fulvous 

 spots. The legs are short, strong and black ; the lobes of the 

 third joint and the base of the claw joint of the tarsi are clothed 

 with white hairs ; there is also an irregular white patch on the 

 outside of each femur. 



I should have wished to refer this insect to one of the host of 

 subgenera found in the subfamily of which Lamia is the type, 

 but the want of a satisfactory plan of distribution of the Longi- 

 corn Coleoptera renders such an attempt almost impossible. The 

 work of a master-mind like that of Lacordaire can alone reduce 

 these subgenerical sections to their true rank and position. I 

 have made the attempt in vain with the work of Mr. Thomson, 

 but have been thwarted by the illogical nature of even his pri- 

 mary sections. These, in the first tribe, Lamiitce, are thus ar- 

 ranged : — * 



I. Acetabula antica integra. 



A. Acetabula antica rotundata (^Acanthoderitce). 



AA. Acetabula antica vel rotundata, vel extus angulata 



(Dorcadionitce), 

 AAA. Acetabula antica extus angulata (^Lnmiitce verae). 

 la. Acetabula antica subintegra (Monochamitce). 



laa. Acetabula antica integra (^Gnomitce). 



11. Acetabula antica valde hientia {^Methiitce). 



I must confess that such a style of tabulation is beyond my 

 comprehension.
