Ihey are to be distinguished from the normal Rhagia of Europe and 

 North America, by the elongated and often curved basal joint of the 

 antennae, by the elongation of the head anteriorly, and by the frequen- 

 cy of carinated elytra, having the interspaces either reticulated or 

 thickly punctured. I feel considerable hesitation in proposing a name 

 for a family which, though in all probability very extensive, is known 

 to us only by the occasional arrival of a somewhat aj^proaching form ; 

 indeed, in the genus Rhagiomorjjha, the eyes are more those of a Ce- 

 rambyx ; in Stenoderus, — to which Macrones is almost too closely 

 allied, — those of a Leptura. Still the points of resemblance as given 

 above are so striking, that I would propose to unite the genera as the 



Family. — Rhagiomorphid.e, Newman. 



In addition to Macrones its contents, as at present published, are 

 as follows. 



Genus. — Rhagiomorpha, Newman. 



This genus is described in the * Annals of Natural History,' v. 21, 

 and contains two divisions : the species in the first are Rha. Leptu- 

 roides, the Stenocorus Lepturoides of Boisduval, 'Faune de I'Oceanie,' 

 479 ; Rha. concolor, the Stenocorus concolor of MacLeay, 'Appendix 

 to King,' ii. 452 ; and Rha. sordida of Newman, 'Ann. Nat. Hist.' v. 

 21. The second division, containing ' species abeiTantes,' should I 

 leave them as Rhagiomorphae, will doubtlessly be separated from the 

 preceding on account of the distinctly carinated elytra, which evince an 

 approach to the following genus. I shall therefore consider these the 



Genus. — Tropis, Newman. 



Containing as the type Tropis ocnlifera, the Rhagiomorpha oculifera 

 of Newman, 'Ann. Nat. Hist.' v. 21 ; and 



Tropis dimidiata. Caput nigrum, glabrum : prothorax flavus, gla- 

 berrimus, nitidissimus : elytra basi flava, apice nigra, splendore 

 chalybeo nitentia, parallela, quasi reticulata, basi fere glabra, 

 singulo 4-carinato : pedes nigri, splendore chalybeo nitentes ; 

 pro- et mesofemoribus flavidis : sternum flavidum, abdomen 

 chalybeum. (Corp. long. *7 unc. lat. 'ISS unc.) 



Inhabits New Holland. There is a mutilated specimen in the ca- 

 binet of the Zoological Society, and a second in that of the Entomo- 

 logical Club.
