the Coleopterous Family Cerarabycidse. 317 



Thoris. 



Prothorax oblongus, irregularis, lateraliter tuberculatus. 

 Femora petiolato-clavata ; tarsi breves, longitudine fere aequales. 



Head exserted, short in front ; upper lip very small ; eyes 

 broadly emarginate. Antennae ( $ ) shorter than the body ; the 

 third joint nearly twice as long as the fourth and fifth together, 

 these three with a short spine at each of their apices. Prothorax 

 oblong, somewhat depressed, irregular, the sides tuberculate. 

 Elytra rather short, parallel, the apex of each emarginate, with 

 the outer angle spined. Legs gradually increasing in length to 

 the posterior; femora petiolate-clavate ; tibiae slightly com- 

 pressed ; tarsi short, nearly equal in length. Pro- and raeso- 

 sterna simple. 



In habit this genus bears only a very slight resemblance to 

 Callirhoe ; nevertheless I have found it difficult to diflferentiate 

 it by any important character, except that of the short and 

 nearly equal tarsi. It is probable that the antennae of the male, 

 which is unknown to me, will afford other characters ; those of 

 the female are shorter than the body, the apical spine, which is 

 very small, disappearing at the sixth joint, and all the joints 

 beyond the third are unusually short. The puncturation of the 

 elytra is quite different from that in Callirhoe or Phoracantha. 



Thoris ehurifera. 



T. rufo-lutea ; elytris maculis flavis impunetatis decern ornatis. 



Hab. Rockhampton (Queensland). 



Reddish luteous, with scattered erect hairs; head finely punc- 

 tured, a sharply impressed longitudinal line in front terminating 

 in an arched groove above the clypeus; prothorax opake, mi- 

 nutely punctured, the disk with five nearly obsolete tubercles, 

 the central one excepted; scutellum hairy, rounded behind; 

 elytra thickly punctured at the base, the punctures passing in- 

 definitely into the surrounding derm, and gradually becoming 

 less frequent posteriorly ; on each elytron five round w^ell- 

 niarked yellow spots, a little raised and entirely without punc- 

 tures, the first, fourth, and fifth spots on the same median line, 

 the third nearer the suture, the second smaller and towards the 

 side; body beneath, legs, and antennae chestnut-red, shining, 

 covered more or less with greyish hairs. Length 5 lines. 



Brototyche. 



Prothorax subquadratus, lateraliter inermis. 



Coxce anticae approximatae ; prostermim carinatum. 



Processus interfemoraHs obtectus. 



Head small ; antennary tubers prominent, the upper margin
