360 NOTES ON AUSTRALIAN COLEOPTERA, 



founded on Olivier's erroneous statement to that effect^ but there 

 seems to be no doubt whatever that Mr. Baly is right in his 

 conclusions. It is quite likely that A. Olivieri may be hilaris, 

 Boisd., but this could only be determined by reference to the type 

 if still in existence. 



AULACOPHORA RiCHMONDENSIS, Sp.nOV. 



Oblongo-ovata ; convexa ; nitida ; flava, labro, mandibulis 

 apice, antennis (basi excepta),metasterno, tibiis (basi excepta), 

 tarsis et elytrorum fasciis 2 latis (altera recta basali, altera 

 arcuata pone medium) nigris aut nigro-piceis ; prothorace 

 quam longiori fere duplo latioii transversim sulcato, antice 

 latera versus sparsim fortiter punctulato ; elytris tenuiter 

 punctulatis. 



Maris segmento ventrali apicali 3-lobato, lobo intermedio 

 toto longitudinaliter profunde concavo. 



Feminae segmento ventrali apicali tequali, postice rotundato. 

 Var. metasterno flavo. [Long. 3-3f, lat. 1^2 lines. 



The eyes are connected by a transverse furrow, immediately 

 above the middle of which is a deep fovea. The antennae are not 

 different in the sexes. The basal joint (and in some examples the 

 second and even the base of the third) is more or less rufous ; 

 joints 3 and 4 are equal inter se. The prothorax is punctured 

 very finely and sparsely except towards the sides of the portion in 

 front of the transverse furrow where the puncturation is strong 

 and conspicuous. 



The previously described Australian species having yellow elytra 

 with large black markings are Olivieri, Baly, pectoralis, Jac, 

 Cartereti, Guer., and hilaris, Boisd., (not recognizably described). 

 Of these the first has antennae totally difierent from those of the 

 present insect, the black markings not forming continuous fascise 

 on the elytra, &c., — the second (from Cape York) has " the pro- 

 thorax impunctate,"— the third (known I think only by a very 

 poor description) has antennae "at least as long as the body" (in 

 this species they reach little behind the middle of the elytra), 

 " thorax a little wider than long " (in this species all but twice as 

 wide as long), yellow legs, &c. The Malayan A. analis, Weber,
