OF NEW ZEALAND. 193 



curved raised lines in the middle behind ; each elytron with four longi- 

 tudinal ridges and two rows of largish punctures between each, elytra 

 palish brown, with a large dark brown triangular mark on the base as 

 wide as the elytra, and a few spots of different sizes. 



Length, if lines. 



NOTE. This is the most common species of the genus.

 fusca, capite thoraceque brunneo-testaceis, elytris testaceis, antennis 

 pedibusque runs ; prothorace inyequali, haud costato ; elytris minus dis- 

 tincte costatis, lateribus apiceque fusco-signatis. 



Long, corp., 3! mm. 



Antenna reddish, the ninth joint scarcely larger than the preceding 

 one, the tenth very broad and transverse, eleventh large, nearly as broad 

 as the tenth. Head of a brownish colour, rugose, without distinct im- 

 pressions. 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 oc- 

 cupied 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 costse, and between 

 these is coarsely sculptured ; but the sculpture is made indistinct by some 

 short rigid setae. Legs reddish ; tarsi rather long and slender. 



OBS. Though this species at first sight is extremely similar to Bi- 

 toma insularis, White, yet it is readily distinguished therefrom by the 

 absence of the distinct costse of that species. 



Tairua (Captain Broun). 



345. B. distans, Sharp; Ann. Mag. Nat. Hist., July, 1876. B. 

 nigro-fusca, opaca, griseo-setosa, elytris rufo-maculatis, pedibus fusco- 

 rufis ; prothorace fere sequali, haud costata, elytris duplo angustiore ; his 

 fortiter punctatis, haud costatis. 



Long, corp., 4 mm. 



Antenna 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 obsoletely sculptured, without distinct ele- 

 vations or depressions, but with grey setae 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 alternate interstices very 

 indistinctly elevated ; the setae rather long and distinct, though not 

 abundant. Underside blackish, very dull. Legs infuscate red. 



Also sent by Captain Broun from Tairua.
