26 Mr. D. Sharp on the 



tennis pedibusque rufis ; prothorace inaequali, hand costato ; elytris 

 minus distincte costatis, lateribus apiceque fusco-signatis. Long. 

 Corp. 3f m. m. 



Antennte reddish, the ninth joint scarcely larger than the 

 preceding one, the tenth verj broad and transverse, eleventh 

 large, nearly as broad as the tenth. Head of a brownish 

 colour, rugose, without distinct impressions. Thorax a good 

 deal narrower than the elytra, not quite so long as broad, nearly 

 straight at the sides, the front angles prominent ; the surface 

 bears some irregular elevations, so that it appears to be occu- 

 pied by large irregular depressions ; in sculpture it is similar 

 to the head. Elytra rather depressed, of a testaceous colour, 

 with some ill-defined darker marks near the sides, and a larger 

 and more distinct one just before the apex ; each elytron bears 

 three or four costaj, and between these is coarsely sculptured ; 

 but the sculpture is made indistinct by some short rigid setse. 

 Legs reddish ; tarsi rather long and slender. 



Tairua (Captain Broun). 



Obs. Though this species at first sight is extremely similar 

 to Bitoma insularisj White, yet it is readily distinguished there- 

 from by the absence of the distinct costse of the thorax of that 

 species. 



Bitoma distans, n. sp. 



B. nigro-fusca, opaca, griseo-setosa, elytris rufo-maculatis, pedibus 

 fusco-rufis ; prothorace fere aequali, baud costato, elytris duplo 

 angustiore ; bis fortiter punctatis, baud costatis. Long. corp. 

 4 m. m. 



Antennae blackish red, with the two joints of the club black. 

 Thorax rather longer than broad, greatly narrower than the 

 elytra, slightly curved at the sides, the front angles acute but 

 only slightly prominent ; the surface very opaque and obso- 

 letely sculptured, without distinct elevations or depressions, 

 but with grey sette arranged in an irregular manner, so as to 

 give a good deal the appearance of depressions between them. 

 Elytra elongate, less dull than the front parts, of a blackish 

 colour, with numerous large but indistinct reddish marks, 

 punctured with rows of crenate punctures, and with the alter- 

 nate interstices very indistinctly elevated ; the setas rather 

 long and distinct, though not abundant. Underside blackish, 

 very dull. Legs infuscate red.
