116 REVISIONAL NOTES ON AUSTRALIAN CARAniD.E, 11., 



A. Elytra with a single row of discoidal foveiform punctures on each. 



B. Elytra 4-punctate, colour cyaneous L. (Scarites) cyaneus, Fabr. 



BB. Elytra with more than two large punctures on each. 



c. Upper surface golden-bronze L. (Carenum) deauratus, Macl. 



^, , f Tj. (Caremtm)miiltiimpres!^ns, Casteln. 



cc. Black \ ' "^ V oi * 



t L. (Laccopterum) humeralis, SI. 



AA. Elytra with several rows of fovetb on each. 



d. Elytra with a non-foveate space along suture (a row of small ocellate 

 punctures in the lateral channel). 

 e. Colour not black. 



f. Upper surface green, with coppery reflections 



L. {Carenum) gemmatns,V\'estw. 



ff. Upper surface dark blue L. {Caremim)foveolatus, Macl. 



ee. Black. 



g. Elytra with three regular rows of large foveas, divided by con- 

 tinuous slightly raised interstices... L. (Carenum) spencei, Westw. 



gg. Elytra with the large fovea? more or less confused 



L. (Carenum) salebrosus, Macl. 



dd. Elytra with space near suture (first interstice) foveate. 



H. General colour black, ocellate pores along lateral margin placed 

 in a deep channel and usually in large depressions. 



i. Elytra with the fovete confused and irregular. (Black) 



L. (Carenum) loculosus, Newm. 



ii. Elytra with four rows of fovea? on each, 



j. Black L. (Laccopterum) macleayi, SI. 



jj. Black, with lateral margins of prothorax and elytra bluish... 



,^ L. {Caremim) foveigerns,-\- Chaud. 



ijj. Black, with lateral margins and bottoms of fovejB of elytra 



bluish L. {Laccopterum) lacunosns, Macl. 



jjjj. Black, with lateral margins and bottoms of fovea? of elytra 



greenish />. {Caremim) foveipennif., Macl. 



HH. Upper surface golden-green, a row of closely placed small ocellate 

 pores along lateral margins. .L.(Laccopterum)darwiniensis, Macl. 



* I suspect that L. humeralis may be conspecific with L. mjdtiiiiqn-essus, 

 and that Castelnau"s type-specimen was aberrant in the number and position 

 of the elytral fovete. Mr. French has recently received J., humeralis from 

 the Roebuck Bay District. 



t It seems possible that with further knowledge L. foveipennis, Macl., L. 

 lacunosns, Macl., and L. macleayi, SI., may come to be considered only 

 colour-varieties of L. foveigerus, Chaud.
