MB. r, p. PASCOE ON THE LONGTCORNIA OF AUSTRALIA. 101 



the disk ; body beneath and legs thinly clothed with long pale-greyish 

 hairs ; the epipleurse of the metathorax with a dense white pile ; an- 

 tennae with the five basal joints covered with loose stiffish hairs, the 

 remainder with a fine uniforna pubescence. Length 12 lines. 

 Allied to S. scutellatus, Hope*, but without any spots on the 

 prothorax, the apex of each elytron strongly spined, the eyes con- 

 siderably more approximate beneath, the metathoracic epipleurse 

 covered with a dense white pile, and other characters. 



OXTMAGIS. 

 Caput antice paulo productum. Ociili prominuli, anguste emarginati, 

 supra distantes. Antennas breviusculae, basi remotae; scapo modice 

 elongato, obconico ; articulis tertio et quarto brevioribus, cylindrieis ; 

 cseteris paulo longioribus et subsequalibus. Palpi breves, articulo 

 ultimo triangular!. Prothorax capita latior, apice angustus, antice 

 utrinque rotundatus, basi bisinuatus, angulis posticis productis. Elytra 

 prothorace multo latiora, oblonga, parallela. Pedes mediocres, antici 

 breviores, postici longiores ; femora in medio incrassata ; tarsi subdi- 

 latati, fere sequales. Acetabula antica integra. Prosternum latum, 

 elevatum, postice transverse dilatatum. Mesosternum elevatum, antice 

 dilatatum et perpendiculare. 

 Nearly related to Strongylwus, Hope, but the palpi short, with 

 the terminal joint triangular, and the pro- and mesosterna pro- 

 duced, with broad opposing perpendicular faces. I have dedicated 

 the species described below to Dr. G-ray. 



OXTMAGIS GrRATII. 



O. fuscus, sparse griseo pubescens ; prothorace lateribus dense albo to- 

 mentoso ; elytris brunneis ; antennis, tibiis tarsisque fulvo-ferrugineis. 



Hah. ? 



Dark brown, with scattered greyish adpressed hairs, each issuing from a 

 small puncture in the derm ; head with a wide semicircular impression 

 between the eyes ; prothorax with a dense pure- white tomentose stripe 

 on each side ; elytra reddish brown, the apex of each rounded ; body 

 beneath thickly pubescent at the sides ; antennae, tibiae, and tarsi yel- 

 lowish ferruginous. Length 11 lines. 



Opsidota albipilosa. 

 O. fusca, supra sparse albo pilosa, infra dense pilosa ; antennis brunneis, 



subtilissime pubescentibus ; tarsis rufescentibus. 

 Hah. South Australia (Gawler). 



* This was the type of my genus Isalium. At the time of proposing it I was 

 under the impression that Strongylurits, Hope, was synonymous with Didymo- 

 cantha, Newm. ; the former author, however, gives 8. scutellatus as the type, not 

 distinguishing it from Didymocantha, but separating Coptopterus.
