Australian Coleoptera. cxiii 



Family 



Stenoderus ostricilla. 



Caput, prothorax, mesothorax ,profemora, mesofemoraque glaberrima, late testacea ; oculi 

 rotundi, antennmque nigra ; metathorax, melafemora, tarsique omnes nigro-picea ; 

 abdomen subtus nigrum fulgore chalybeo splendidum ; elytra 4-carinata, testacea, 

 apicibus late purpureo-nigris. (Corp. long. - 5 — '6 unc. Elytrorum lat. max. - 125 

 — '15 unc.) 



The head, prothorax, mesothorax, profemora and mesofemora are smooth, very 

 shining and bright testaceous ; the eyes, which are round, and the antennae are black 

 and shining ; the metathorax, metafemora and all the tarsi are pitchy black ; the ab- 

 domen beneath is black but respleadent with a steel-blue lustre ; the elytra are bright 

 testaceous approaching to orange but without gloss, indeed they exhibit somewhat of 

 a velvety surface, and have a broad apical band of black resplendent with a lovely 

 metallic purple ; this purple colour does not quite extend to the anterior margin of 

 the black : each elytron has four raised longitudinal keels. 



These insects are constant to two sizes, as designated above : the difference is pro- 

 bably sexual. 



Hab. — North of New Holland. In Mr. S. Stevens's collection. 



Family — Pho r aca n thi d^e . 



Genus — Skeletodes, Neivman. 



Generi noslro Callirhoe nimis affinis, at corpore, antennis, oculis manifestb differt : 

 gracilius ; antenna longiores articulis 3 — 5 spina apicali armatis, 3tii spina me- 

 diocris, 4ti minor, bli minima ; oculi 4, binis epicranii approximatis, minoribus, 

 ovatis, binis genarum majoribus, subrotundis ; prothorax latitudine duplb longior 

 lateribus subparallelus, inermis ; elytra lateribus parallela, dorso complanata, 

 apice rotundala inermia ; pedes longi femorum dimidio apicali incrassato. 



Skeletodes Tetrops. 



Fusca, testaceo varia,puncta ; elytra basi, plagis discoidalibus obliquis, apiceque fusca ; 

 pedes testacei,metafemorum apicibus fuscis. (Corp. long. *425 unc. Elytrorum lat. 

 max. "08 unc.) 



Head porrected on the plane of the prothorax with which it exactly corresponds in 

 width ; antennae as long as the body, beset with scattered long and short hairs ; the 

 third joint armed with a strong apical spine, the second with a smaller one, the third 

 with a very small one, the remainder unarmed ; each joint is dark at the base and 

 apex, pale in the middle : the eye being completely divided at the base of the antenna? 

 by a large scale or plate evidently connected with the antennae, the insect becomes 

 possessed of four distinct eyes, a character already noticed in Tessaromma, Astathes, 

 and several other genera of longicorn Coleoptera ; the upper or epicranial eyes are
