they are seriate-punctate, regularly near the suture, not so beyond; the 

 scutellar region is depressed; there is a distinct, though not large, basal 

 elevation of the 3rd interstices, and on the summit of the apical declivity 

 on each elytron there is a pair of small nodosities. 



Antennae with the club densely pubescent, broad and Particulate; 

 basal joint but little exposed above; 2nd thick, as long as broad; 3rd 

 slender, not elongate, yet longer than it is broad; 4th and 5th slightly 

 longer than broad; joints 6-8 moniliform and small; 9th rather broader 

 than its predecessor, not dull and pubescent, and only about a third of 

 the width of the club. 



Only a single species, N . brevis (1353), resembles this, which, how- 

 ever, is even smaller, with more-convex elytra, rounded shoulders, and 

 different thoracic impressions and lobes. 



Length, nearly 2 mm. ; breadth, 1 mm. 



Mount Pirongia. December, 1909. Unique. 



In its natural condition it is covered with greyish sappy matter, so 

 that its real sculpture and thoracic lobes cannot be seen. The removal 

 of that substance by degrees with the point of a needle and brushing 

 with benzene is a very delicate and tedious operation in the case of a 

 somewhat asperate insect about the size of a pin's head. At any rate, 

 the cleaning without damage and the subsequent description of this 

 solitary specimen occupied a whole day. 



Dr. Sharp's Bitoma sellata (1927) should be placed in this genus. 

 It is not in the least like the European Bitoma, and may be readily 

 separated from Ulojiotus by its biarticulate club. 



3225. Bitoma maura sp. nov. Bitoma Herbst, Man. N.Z. Coleopt., 

 p. 192. 



Elongate, subdepressed, entirely dull black, with a few elongate, scale- 

 like, yellowish setae. 



Head rather smaller than thorax, with granular sculpture. Eyes of 

 moderate size. Antennae inserted below the edge of the forehead; the 

 exposed portion of the basal joint not longer than the thick 2nd, which 

 is narrowed towards its base; 3rd slender, longer than adjoining ones; 

 4th and 5th about equal, longer than broad; 8th and 9th moniliform; 

 the 10th obconical, twice as broad as the 9th, about as long as broad; 

 11th oblong, as broad as the 10th; these two joints are densely and finely 

 pubescent, and form the club. Thorax not lobate, widest near the front, 

 gradually narrowed backwards, with obtuse angles; the surface a little 

 uneven, with a large depression on the middle of the disc; its sculpture 

 is ill-defined, but appears to be granular; it is slightly broader than 

 long. Elytra almost thrice the length of thorax, evidently broader, their 

 sides parallel; they are broadly impressed before the middle and behind 

 the scutellum, their sculpture seems to consist of closely placed series of 

 granules. 



So far as superficial appearance is concerned, this species stands alone. 

 The club is unusually elongate. 



Our B. insidaris and B. vicina (343 and 344), so far as can be judged 

 without dissection, will probably remain in this genus. All the other 

 species are certainly different from the type of the genus, the European 

 B. crenata. 



Length, 2k mm. ; breadth, nearly 1 mm. 



Waimarino; elevation, 2,600 ft.; January, 1910. One only could 

 be found.
