534 INSECTA. 



with shorter antennae, thickest, and almost serrated at the extre- 

 mity(l). 



In those that inhabit France, such as the 



N. riifa, h.; or the Lepture a ifiiis HrangUs, Geoff.; lb., 74, 

 i, 6, the antennae ar° filiform and as long as the body(2). 

 Those in which the t lytra are short and sguamiform will consti- 

 tute the subgenus 



Necydalis proper, 



Which corresponds to the genus Molorchus of Fabricius. Its type 

 is the Necydalis major of Linnaeus and Geoffroy — Oliv. lb. I, 1. 

 Found in old Willows in June and July(3). 



Certain Insects generally proper to the African islands. 

 New Holland, New Ireland and New Zealand, ambiguous in 

 several respects, and which, in a natural order, should per- 

 haps be placed between the Laniiarise and the Lepturetae, 

 will terminate the division of the Cerambycini. 



Their palpi are almost filiform, the last joint almost cylin- 

 drical and somewhat attenuated towards the base ; their tho- 

 rax is usually smooth or but slightly uneven, without acute 

 tubercles, and becomes widened posteriorly, or presents the 

 form of a trapezium or truncated cone, as in the last tribe of 

 this family ; the abdomen in the greater number is almost in 

 the form of a reversed triangle, and the elytra are truncated at 

 the extremity. 



These Insects form four genera. 



DiSTiCHOCERA, Kirby. 



Where the antennae of the males are gradually dilated towards the 

 extremity, and their joints, from the third, are forked or divided 

 into two branches at the end(4).

(2) The Necydales atra M\f\. prxusta. Fab., and the N. femorata of Germar, are 

 analogous. 



(3) See Fabricius, Olivier, Kliig, Kirby, and Schocnhcrr. 



The Stenocorus hemipterus of Fabricius, which should apparently be placed here 

 in a natural order, approximates more closely to the Stenocori of Germar and De- 

 jean.
