Oenera and Species of Coleoptera. 4G3 



Narrowly oblong:, rodili.sh brown or dark brown, sliji^htly shining' ; 

 head finoly puneturod ; pR)thorax with very minute punctures, tho 

 eniargination at the apex very sliallow; elytra rather ttuely lineate- 

 puuctate, the alternate lines slightly elevated (about nine on each 

 elytron) and garnished with small glossy pustular or bubble-like gra- 

 nules placed at irregular intervals on those lines ; body beneatli dark 

 chestnut-brown, or paler ; legs also varying from reddish to brown, and 

 shining. Length 8 lines. 



Apparently allied to Cilibe granulosus, Do Br., from New Zealand?, 

 but essentially different in the very minute, almost obsolete punc- 

 tation of the prothorax. It varies in colour, but the margins of 

 the prothorax are paler than the disk. 



Helceus* consularis, 



H. obovatus, niger, nitidus, marginibus latis valde reflexis ; prothorace in 

 medio dentato-carinato, dente posteriore magno spiniformi ; scutello 

 carinato ; elytris impunctatis, marginibus exceptis, utroque costa cre- 

 nata et linea tuberculata externa instructo. 



Hab. Western Australia. 



Obovate, glabrous, black, shining ; prothorax with a toothed carina 

 in the middle, the posterior tooth large, in the form of a compressed 

 triangular spine; scutellum transversely triangular, keeled in the 

 middle ; elytra impunctate, the broad strongly reflexed margins faintly 

 punctured, their edges terminated by an erect, naiTow border, the raised 

 suture having on each side at a short distance a shai-p costa crenated on 

 both sides, and externally near the angle fomied by the reflected margin 

 a line of small tubercles which do not, however, extend to the base j 

 body beneath glabrous, black, shining; legs rugose. Length 11 lines. 



About the average shape and size of H. colossus, but with elytral 

 costae as in H, Peronii. The following is very nearly allied. 



Helceus moniliferus, 



II. ovatus, glaber, brunneus, nitidus, marginibus latis, explanatis ; scutello 

 semicirculari, baud carinato ; elytris fere obsolete punctatis, cieteris ut 

 in lircecedente. 



Hah. South Australia. 



Broader and paler than the last, the margins scarcely reflexed ; the 

 scutellum rounded posteriorly, or semicircular, without a keel ; elytra 

 with the lateral costae less crenated, and the exterior line of tubercles 

 extending to the base, and the pimctation, though minute, very evident 

 under the lens. Length 11 lines.
