Genera and Species of Coleoptcra. 361 



would bo with Cli/ti(s. The genus must be worked out in its entirety, 

 it' it is to be divided satisfactorily. Among the Cli/ti, however, 

 there seems to me to be two groups which, by theii' habit principally, 

 deserve to be distinguished — one liJiapliuma, Thoms., including C. 

 quad I' t col or, Lap., C, leucoacuicUahis, Hope, and C. placid us, Pasc, 

 the other, unnamed, comprising C. hmatiis, Newm., C. Ilardiviclcii, 

 White, and C. cruentatus, Pasc. Both these groups appear to bo 

 well limited and well marked ; but their technical characters, I fear, 

 will not be very valuable. 



ZoEDiA [Ccrambycida)]. 



Head subquadrate m front, constricted into a neck behind. Eyes narrow, 

 elongate, deeply emarginated. Antennae eleven-jointed, filiform, as 

 long as the body; all the joints, except the second, nearly equal in 

 length, the basal thickened, obconic. Palpi with the last joint narrowly 

 triangular, obliquely truncate. Prothorax nearly as broad as long, 

 narrow anteriorly, a stout tubercle at the side. Elytra broader than 

 the prothorax, subparallel, rounded at the apex. Legs slender; tarsi 

 nearly linear, the basal joint elongate. Pro- and mesostema simple. 



Near TUlomorplia and Eiiderces, but differing completely in the 

 form of the head, the prothorax, &c. With Attodem* it agrees in 

 having the prothorax of a similar character, although more robust, and 

 in its neck ; but the pecuHar round, ant-like head of the latter, and 

 its perfectly entire eyes, place it in a different subfamily. Of the two 

 species described below, I have only seen one individual of each. 



Zoedia triangidaris. (PL XYII. f. 3.) 



A. niger, sericeo-pubescens ; capite, prothorace elytrisque macula magna 

 ti'iangulari rufis ; autennis rufis, articulo basali infuscato. 



Hah. Australia (Melbom'ne). 



Head caualicidate in front, finely pimctm-ed, and with the prothorax 

 bro\vnish red, inclining to feiTUginous ; eyes narrow, oblique, slightly 

 emarginate, pale red ; antennae rather shorter than the body, red, the 

 basal joint clouded with brown ; palpi and mandibles red ; prothorax 

 longer than broad, swelling out considerably at the side behind the 

 middle, where it is as wide as the head, very narrow and produced 

 anteriorly; scutellum triangular, dull brown; elytra wider than the 

 prothorax, especially at the base, the sides parallel, abruptly deflexed 

 and roimded posteriorly, brownish black, with silky and somewhat 

 silvery pubescence, a large triangular reddish patch, the apex com- 



* Pseudocephala, Newm. This name being preoccupied, as well as a more 

 recent one, OrtJwcephalus, Mr. Thomson informs me {m lift.) that he intends to 

 propose Attodera in his forthcoming work on the Longicorns.
