This species, T. diaticollis, Macl, and 7. Auguste, 
Blackb., are easily distinguishable from all the other Aus- 
tralian species of Trox known to me by the numerous and 
conspicuous rows of fine, brightly fulvous sete on their 
elytra. They resemble each other considerably, but are 
separated by good characters—the inequalities of the prono- 
tum being in the other two species strong cariniform ridges, 
in this one feeble obtuse convexities; the subsutural carina 
of the elytra being in the other two continuous along the 
sides of the scutellum, in this species widely disconnected 
from the short elevation that margins the sides of the scutel- 
lum in their front part; the elytral sete being very evi- 
dently shorter, less erect, in the other two than in this 
Species, those setae, moreover, in.the other two not being 
regularly spaced (on account of two or three sete being 
placed close together here and there as a fascicle on the 
apex of a scarcely defined tubercle), while in the present 
species each seta is isolated, and all are very equally sepa- 
rated inter se.
