male or female ; if the latter, the antenna? of the male may 

 differ considerably ; but it is, without doubt, allied to Phacodes, 

 Newm., in which genus the variations in the characters furnished 

 by those organs are very disagreeable to the systematist. 



Thephantes clavatus, 



T. fuscus, pube grisea, albeseente vage intermixta tectus; capita 

 prothoraceque subferrugineis. 



Hab, Darling Downs (Australia). 



Dark brown, covered with a rather coarse and loose greyish 

 pubescence, indefinitely mixed with small spots of whitish ; the 

 head and prothorax somewhat ferruginous, the upper surface 

 with small dispersed punctures, those on the elytra nearly dis- 

 appearing posteriorly and furnished each with a stiffish erect 

 hair ; second and third joints of the antennae equal, shorter than 

 the scape, the succeeding about the length of the scape; femora 

 exceedingly clavate ; legs with longish hairs. Length 7 lines. 



ZOODES. 



Scapus brevis, pyriformis. 



Prothorax convexus, transversus, postice angustior, lateraliter baud 

 excavatus. 



These characters appear to me to cut this insect off from 

 Stromatium, to which Mr. White has doubtfully referred the 

 only known species, Stromatium ? maculatum (Cat. Long. Brit. 

 Mus. p. 301, pi. 8. fig. 4). The name adopted is a manuscript 

 one, under which it stands in M. Chevrolat's collection. 



The following names applied to genera of the Cerambycidse 

 I have changed, as they had been previously used in other 

 groups : — 



TrichophoruSjSen?., non Temminck (Turdidae) : name proposed, Crocidastus. 

 Petalodes, Newm., non Wesmael (Braconidae) „ Anatisis. 



Couothorax, J. Thorns., non Jeckel (Curcuhonidae) „ Massicus.

The existence of several genera among Menispermaceae with 

 exalbuminous seeds was not known to botanists until I first in- 

 dicated the fact in this genus, which was established in 1851; 

 for it was then doubtful whether the genus Spirospermum
