572 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiii., 



of the abdomen, which are deeply infuscated) is paler than the 

 prothorax and elytra, these being of a rather bright llavous; the 

 infuscation of the legs is not very deep. The dilated, sutural 

 patch is much as in the preceding species. 



The five females commented upon, under the preceding species, 

 may possibly belong to this one, but the abdomen of each is 

 entirely pale (as in the male of that species), not bicolorous (as 

 in the male of this species). 



COPIDITA TENUICORNIS, n.Sp. 



9. Pale flavous, tips of mandibles blackish, pronotum with 

 three, conspicuous, but not very sharply defined, infuscate lines, 

 elytra with very feeble infuscate lines. 



Head rather large, with irregularly distributed and not very 

 large, but sharply defined punctures; mandibles bifid Eyes 

 large, prominent, widely notched, and rather closer together than 

 usual in the genus. Antennae very long and thin, eleventh joint 

 moderately curved, distinctly longer than tenth, and with a vague 

 remnant of doubling at the apical third. Prothorax slightly 

 longer than wide, sides gently dilated from near the base, which 

 is narrowly upturned, with a shallow and vaguely impressed, 

 irregular, median line, and feeble impressions elsewhere; with 

 fairly dense punctures. Elytra much wider than prothorax, each 

 with four discal elevations, of ^vhich the third (apart from its 

 colour) is scarcely traceable; with dense but rather ill-defined 

 punctures. Fifth segment of abdomen rather long, its tip 

 rounded. Legs rather long and thin. Length, 12-15 mm. 



Hah. — Queensland: Cairns (E. Allen). 



The three specimens before me are apparently all females; 

 they are not very close in appearance to any previously described 

 species. The infuscated lines on the elytra are fairly distinct to 

 the naked eye, but less defined under a lens, and are due to the 

 elevations being somewhat paler than the adjacent parts. The 

 antennae are unusually thin, and extend to the tip of the elytra. 

 The prothoracic punctures are sharply defined on one specimen, 

 much more so than on the type.
