the median elevations much smaller than in .1. phy ma fades, and 

 their sculpture rather finer. From A. deceits it is distinguished by 

 the greater size, longer antennas, larger tubercles on the head, as 

 well as by the differences in colour.

2230. A. auxins, n.s. Subopaque, dark blackish-brown, very 

 dark below and along the sides ; most part of femora also dark, but 

 with their extremity, and the tibiae (except the blackish apex), ob- 

 scure-red, tarsi also variegate ; antennae shining, red, club darker. 



When compared with A. vates the following differences may be 

 noticed : Antenna thicker, the joints less nodiform at apex ; the 

 three first joints are more distinctly pubescent than the others, the 

 club more finely but densely, third joint quite one-third longer than 

 second. The clothing is darker, more flavous, less dense on thorax, 

 so that bare spots are seen. The elytra are, on the dorsum only, a 

 little and irregularly spotted. The carina is just perceptibly more 

 angulate in the middle. The legs have much less pubescence. The 

 insect itself is smaller.

OBS. A variety of A. vates exists for which I propose the name 

 A. nigrofasciatus . It has a broad, almost black, fascia, in line with 

 the hind thighs, but not reaching the sides. The third joint of the 

 antennae is about one-third longer than the second : Dr. Sharp de- 

 scribes that joint, in A. vates, as being "one and a half times 

 longer," but I have no specimen of the species with such a long 

 third joint ; perhaps, however, he made a mistake in estimating the 

 relative lengths. 



Another variety, which occurs on Mount Arthur, may bear the 

 name A. aspersus. The darker hairs are inconspicuous, but the grey 

 form large spots on the elytra, often assuming the form of large 

 irregular somewhat angular spaces. Antennae similar to A. nigro- 

 fasciatus. Legs obscure-red. It may be distinguished from A. tessel- 

 latus by the shape of the eye. 



These two forms may ultimately prove to be distinct species. 



2231. A. laetabilis, n.s. Variegate, infuscate-red, legs a little 

 paler ; middle of femora, last tarsal joint, and extremity of joints of 

 antennae fuscous ; clothing less dense on thorax than on elytra, 

 fulvous and grey intermingled, and with some small black spots on 

 the third, fifth, and seventh interstices, besides two larger indefinite 

 ones on the declivity, the grey hairs most conspicuous on the third 

 interstices. 



Its nearest ally is A. discedens, from which this differs in having 

 the antenna just twice the length of the whole body, they are also 

 rather thicker, joints 3-8 are more nodose at the tip, the ninth quite 

 double the length of the tenth and eleventh conjointly. The thorax
