excessively transverse as in alpicola, Blackb.; by its pronotum 

 very evidently more feebly and sparsely punctulate than in 

 Adelaides, Blackb., and by its size notably smaller, its form very 

 much less parallel, its tibiae and antennal club much more deeply 

 black in colour and its elytra much less extensively rufescent 

 towards the apex than in eyrense, Blackb.

This species is a very distinct one. It is the only Trogoderma 

 known to me having a well defined coloured pattern on the 

 elytra in combination with prosternal sulci open behind. The 

 pilosity on the testaceous parts of the elytra is of testaceous 

 colour, and there is also some thin whitish pilosity on the pro- 

 notum.

 remarks (above) on Trogoderma.

 In some examples the tibiae are piceous rather than black, and 

 the knees even rufescerft. The most distinctive character of this 

 species and the next is the eight-jointed antennal club of the 

 male. To a casual glance the antennae seem to be all club, but 

 on close examination it is seen that there is a single very small
