Australian Longicorn Beetles. 79 



I have seen but one example of this remarkable insect, which 

 was presented to me by my friend the late Rev. J. W. Horsley. 



Brachopsis, new Genus (/3pa^vc o\pig). 



Head slightly produced in front, abruptly truncate, with the 

 sides parallel ; deeply furrowed between the eyes. Eyes round. 

 Antenna filiform, with the 1st joint long, clavate, equalling the 

 three following in length ; 2nd, short, rounded ; 3rd, long ; 4th, 

 much shorter ; and the remainder rapidly decreasing in length. 

 Thorax cylindrical, the sides slightly projecting, with obtuse 

 tubercles. Elytra gradually tapering to a point, gaping at the 

 suture, and of the same length as the body. Abdomen long, spatu- 

 late. Legs short, somewhat robust, with the femora clavate. 



This genus differs from Macrones in the less projecting head, 

 unarmed thorax, and shorter and stronger legs, besides other 

 characters. This and the two preceding genera form a very 

 natural group. 



Brachopsis concolor. (PI. IV. fig. 4.) 



Dark chesnut brown, with the tips of the first joint of the an- 

 tennae, forehead, face, and a longitudinal line along the upper 

 surface of thorax, black. Elytra marked with four elevated lon- 

 gitudinal ridges. 



Hab. Van Diemen's Land. 



Length \ inch. 



In the collection of the British Museum. 



Stenoderus, Dejean. 

 Stenoderus maculicornis. (PI. IV. fig. 2.) 



Dull orange, with the antennae, except the fourth, fifth and 

 sixth joints, black, the latter nearly white, tipped with black, and 

 with the eyes, apices of elytra, apices of hinder femora, apices of 

 all the tibiae, and three terminal joints of tarsi, also black. 



Head and thorax impunctate, opaque. Elytra punctate, with 

 five elevated striae, two vanishing before the shoulders. 



Length -^ inch.
