328 MISCELLANEA ENTOMOLOGICA, 



Caput parvum. 



Thorax parvus laevis orbicularis. 

 Elytra magna ovata subplana. 

 Pedes ut in Graspedophorus. 



Platylytron amplipenne. 

 Long. 9 lin. 



Nigrum subnitidum, capite antice utrinque foveato, thorace 



leevi antice subemarginato postice subtruncato ad latera 



rotundato late marginato — margine reflexo — dorso canali- 



culato ad basin utrinque profunde impresso, elytris sub- 



planis latis oblongis profunde striatis — interstitiis convexis 



— lateribus apiceque rugose punctatis. 



The head is smooth, and the fovea on each side of the face is 



short. The thorax is smooth and nearly circular, though a little 



emarginate in front and truncate behind, the dorsal line is deeply 



marked, and there are two deep impressions at the base near the 



posterior angles. The sides are rounded and not narrower 



behind than in front, with a broad reflexed margin. The elytra 



are broad, flat, rounded at the humeral angles, broadly rounded 



at the apex, deeply striated and roughly punctured towards the 



apex and sides. The legs are rather slender. 



I received several specimens of this insect from King George's 

 Sound some years ago. 



Baron de Chaudoir has given the generic name of Goptocar- 

 pus to the insect formerly known as Oocles Australis Dej. He 

 gives as the chief characters which distinguish it from Codes 

 proper — the adherence of the paraglossse to the sides of the 

 labium, the absence of spongy covering on a large portion of the 

 under side of the first joint of the anterior tarsi, and the enor- 

 mous dilatation of the three first joints of the same tarsi in the 

 male. It is probable that these characters are common to all 

 the Codes of Australia, the tarsal characters certainly are in all 

 those species which I have had an opportunity of examining. 

 I shall therefore adopt Baron de Chaudoir's genus Goptocarpus for
