OF NEW ZK ALAND. S95 



transversal, sides explauated and trilobed ; anterior lobe large, acute 

 in front, the indentation behind it about one-half its size, the next 

 lobe small, the basal minute, forming the posterior angle ; disc 

 destitute of distinct depressions, granulate. Elytra oblong, with 

 rows of closely-placed punctures, appearing as if transversely 

 rugose ; they bear (on each) about six tubercles behind the middle, 

 those near the hind declivity most conspicuous. Legs stout. 



Smaller and relatively broader than U. asper, the wing-cases 

 differently sculptured. It is rendered distinct by the unusual 

 reduction of the ninth antennal joint, so that the structure of the 

 club is just intermediate between that of the more orthodox Ulonotii 

 and the genus Ahlahus. Should other forms be discovered possessing 

 antennae of similar structure, it may become expedient to alter the 

 generic diagnosis of Ulonotus, so as to admit such species and also 

 all those now belonging to Ablahus.

Bitoma (p- 192). 



1596. B. SCita, 'i-s. Body elongate, moderately convex, sub- 

 opaque, variegate ; head and thorax obscure rufo-fuscous, legs pale- 

 brown, antennae and front of head rufescent ; tarsi, thoracic lobes, 

 and most of the wing-cases testaceous ; the sides, apex, and a broad 

 sutural space not reaching the base and furcate in front, brownish 

 (elytra), on the interstices some small pale elevations, there being 

 five on the third, and others near the sides. 



Head coarsely granulate, broadly bi-impressed longitudinally. 

 Prothorax granulated, with some rather deep and broad impressions ; 

 its sides explanate, with a deep median indentation, the anterior lobe 

 largest, the other with uneven edges, so as to appear as if formed of 

 three or four denticles. Elytra with eight or nine rows of quadrate 

 punctures, clothed with fine pale setse. Legs stout, tibia3 ciliated 

 with fuscous setffi similar to those bordering the elytra. 



Allied to B. lobata, larger, broader, much more brightly 

 coloured, &c.

One in my own collection. Whangarata, near Tuakau. 



1597- B. guttata, 5Z.S. Elongate-oblong, moderately convex ; 

 elytra shining, piceous, with (on each) two elongate, raised, basal 

 and other ill-defined spots brick-red ; legs and antenna obscure 

 fusco-rufous, head and thorax with two large, raised greyish spots 

 on each, formed of scale-like matter. 



Head granulated. Prothorax bilobed, the lobes of equal length, 

 the posterior widely emarginate ; its surface granulate, with de- 

 pressions similar to those seen in B. rugosa, B. lobata, and B. scita. 

 Elytra with several rows of punctures, interstices almost smooth, 

 clothed wdth fine yellowish setse or short hairs. Legs setigerous, 

 stout. 



Its affinities are with B. rugosa and the other two species referred 

 to above : from the first it differs in having the thorax lobate, &c., 

 whilst the rugose appearance of the elytral sculpture and almost
