386 COLEOPTERA 



rounded or trapezeiform in front. Antenna often long and slender, 

 filiform or slightly depressed near the extremity, sometimes moderate or 

 short, and gradually incrassated ; their apical joint nearly always larger 

 than the penultimate. Eyes of variable form, generally small, more or 

 less distant from the thorax ; the latter variable. Elytra sometimes 

 strongly embracing the body, often otherwise ; epipleural folds entire 

 behind. Legs long among the majority ; front coxae globose ; tibial 

 spurs absent or hardly distinct; tarsi sometimes brush-like underneath; 

 the anterior, and often the intermediate, dilated in the males ; their 

 penultimate joint sometimes bilobed. Intercoxal process rarely narrow 

 and acute, generally broad and rounded in front. Metasternum variable ; 

 its episterna moderately wide or narrow, parallel. Mesostcrnum decli- 

 vous, slightly (or not at all) concave, rarely horizontal and furcate. 

 Prosternal process bent back behind. Body variable.

 more or less convex, sometimes only slightly convex, rounded and mar- 

 gined laterally, usually narrowed posteriorly, emarginate in front, trun- 

 cated or slightly emarginated at the base, with its hind angles variable.

Adelium is a common Australian genus ; but it has not previously 

 been found in New Zealand. This species may be placed after A. 

 proximum, although it is not closely allied. The sculpture of the elytra 

 is very distinctive (lines of fine punctures embracing oval, oblong, and 

 a few linear spaces, all of a very irregular character).
