and Species of Longicorn Coleoptera. 1 7 



Nyssicus. 



Head short, broader in front ; eyes large, reniform ; maxillary 

 palpi larger than the labial, the two last joints obconic ; antennae 

 long, the third to the sixth or seventh joints strongly spined at 

 the apex; prothorax unequal, the sides armed; elytra elongate, 

 biapiculate ; legs long ; femora clavate, unarmed. 



This genus bears the MS. name of Holacanlhus, Blanch., in 

 some collections ; but that word has been long ago used for a 

 genus of fishes. It is chiefly distinguished from Eburia by its 

 long maxillary palpi, and clavate femora. The type is N. qua- 

 drigutlalus, 01. 



Eroschema. 



Head slightly produced in front ; eyes rather large, reniform ; 

 antennae shorter than the body, stout, hairy towards the base, the 

 joints (except the second) sub-equal, dilated on one side ; palpi 

 short, the last joint subcylindrical, truncate ; external maxillary 

 lobe produced and rounded at the end ; prothorax constricted 

 almost into a neck anteriorly, its side with a stout tooth, the disc 

 unequal ; elytra parallel, depressed ; legs short, last tarsal joint 

 small. 



The place of this very remarkable genus is, I think, near 

 Pteroj)laliis, from which it differs in the palpi, constricted pro- 

 thorax, head, &c. 



Eroschema Purveri. (PI. H. fig. 2.) 



E. hirsuta, atra, infra nitida ; prothorace maculis duabus rubris ; 



elytris rubris, quadricarinatis, interstitiis punctatis ; antennis 



articulis quinque basalibus barbatis. 

 Australia (Sydney). 



Black, clothed above with dense short half erect hairs, beneath 

 smooth and shining; prothorax with a smooth spot at the anterior 

 margin, and another behind, and with the elytra orange red,- the 

 latter having each a sutural and three other raised lines, the inter- 

 stices thickly punctured ; legs very hairy. 



Length 5 lines. 



I have the pleasure of dedicating this to John A. Power, Esq., 

 M. D., so well known as the discoverer of a vast number of our 

 native insects, and to whose kindness there are few British col- 

 lectors who are not indebted for some of their rarest specimens.
