Caloneceus [Mtidulidae]. 

 Thomson, Arch. Ent. i. p. 117. 



Calonecrus rufipes. 



C. rufo-flava ; oculis elytrisqiie nigris. 



Jlab. Borneo. 



Entirely reddish -yellow, except the eyes and elytra, which are hlack ; 

 head and prothorax finely, elytra more coarsely punctured ; sides of the 

 latter, pygidium, femora and tihise pubescent. Length 3 lines. 



Proportionally a more slender form than C. Wallacei, Thoms., and 

 altogether less robust, with the antennae and legs reddish-yeUow, 

 and not black as in that species. 



Peostomis [Cucujidse]. 

 LatreiUe, Fam. Nat. du Regno An. p. 397. 



Prostomis morsitans. (PL V. fig. 6.) 



P. oblongus, testaceus vel piceo-testaceus ; prothorace transverse j elytris 

 pimctato-striatis. 



Hah. India (Darjeeling). 



Larger and proportionally broader than P. mandihidans, the pro- 

 thorax transverse, the antennae shorter, &c. Length 4 lines. 



In the only two specimens which I have seen (in the British 

 Museum), one is very much darker than the other. Mr. Bakewell 

 has another very distinct species from Melbourne. 



Ehyssopeea [Cucujidae]. 



Head small, slightly exserted, nan*owed anteriorly. Antennae of moderate 

 length, the first joint thick, abruptly contracted at its base, the rest 

 more or less ovato-triangular, the last three stouter, forming a loose 

 oblong club. Eyes transverse, rather prominent. Mandibles bidentate at 

 the apex. Labrum long, narrow, roimded anteriorly. Palpi claviform, the 

 last joint broadly ovate, obliquely truncate, the maxillary much larger 

 than the labial, and widely separated at their origin. Mentum subqua- 

 drate, not larger than the labium, which is transverse and emarginate 

 anteriorly ; external maxillary lobe broad, strongly ciliated, inner very 

 narrow. Prothorax subcordate, scarcely sinuated in front. Elytra 

 much broader than the prothorax, parallel, slightly depressed. Legs
