ON THE STENOCHORIDiE OF NEW HOLLAND. 195 



Section 3. Fissipennes. 



Antennae spinosse, thorace insequali tuberculato seu denticulato, 

 apicibus elytrorum transverse truncatis, baud spinosis. 



Gen. CoPTOCERCus', Hope, nov. gen. 

 Caput antice rugosum, antennis spinoso-toraentosis. Thorax fere cyUndricus, tuber- 

 culatus. Elytra parallela thorace latiora, ad apicem parum contracta, transverse 

 fissa, baud spinosa. Corpus infra convexum, antennis pedibusque fere ut in Sten. 

 Roei conformatis. 

 Type of tbe Genus, Stenochorus biguttafus of Donovan. 



CoPTocERCUs BiGUTTATus, Donovan, vid. pi. 2. fig. 7. 

 Copt, biguttatus, thorace mutico, ferrugineus, elytris antice punctato-rugosis, testaceo- 

 maculatis, bidentatis, macula Jiava. 

 Long. lin. 8 ; lat. lin. 2. 



I received this insect from Mr. Donovan, and therefore have no doubt respecting the 

 individual species. The elytra, according to the above description, can scarcely be 

 considered as bidentate ; they appear as if they were abruptly broken off at their apex. 

 The sexes vary very much in size. 



CoPTOCERCUS SEXMACULATUS. 



Copt, niger ; antennis brunneis ; thorace tuberculato et rugoso ; elytris 6 maculis luteis 

 notatis, pedibus rufescentibus. 

 Descr. — Caput atrum, antennis brunneis. Thorax utrinque denticulatus, insequalis, 

 rugosus, tuberculatus, macula media elevata et glabra. Elytra nigra antice vario- 

 loso-punctata, postice punctis minoribus, sex-maculata, macula 1"'' lutea paullo 

 infra basin, 2''* fere media seu melius fasciata, 3"* apicali pallidiore. Corpus infra 

 cinereo-piceum ; pedibus rufo-brunneis. 

 Long. lin. 7 ; lat. lin. If. 



This species, which appears to have escaped the notice of entomologists, is abundant. 

 1 suspect that the male sex will have the denticulation on each side of the thorax more 

 marked than in the female described. 



CoPTOCERCUS UNIFASCIATUS. 



Tab. XIL Fig. 6. 

 Copt, ater, thorace ineequali tuberculato, elytris nigris punctatis et jlavo-fasciatis, punctis 

 ternis, maculisque minutis in singula, inter basin et mediam fasciam positis. 



' Coptocercua, from Koirru, scindo, and Kipms, Cauda.
