526 COLEOPTERA. 



The very unequal thoracic lobes and discal sculpture, in conjunction 

 with the arrangement of the elytral nodosities, distinguish this species. 



Length, 4 mm. ; breadth, H mm. 



Routeburn, north-west of Lake Wakatipu. My specimen, with a tibia 

 broken off, was found by Mr. T. Hall on the 11th February, 1914. 



Notoulus Broun. Man. N.Z. Coleopt., p. 183. 

 4048. Notoulus discors sp. nov. 



Oblong, moderately convex, opaque ; fuscous, legs infuscate-red, antennae 

 and tarsi paler ; irregularly clothed with depressed yellow, and greyish, 

 curled, suberect setae, these latter most conspicuous, and forming on the 

 elytra a pair of elongate basal crests and four subrotundate ones on top 

 of the posterior declivity. 



Head fully half the width of thorax, indistinctly sculptured, somewhat 

 dilated in front of the prominent eyes and covering the basal joint of the 

 antennae. Thorax a third broader than long, base and apex slightly rounded 

 in the middle, the latter bisinuate, its subacute angles extending to the 

 front of the eyes ; its sides explanate, the anterior lobe half the whole length, 

 the second very much shorter ; disc on a higher plane, indefinitely granulate, 

 with three rounded basal impressions, the central one smallest, there are 

 two frontal ones, and a large but shallow and irregular one along the middle. 

 Eh'tra oblong, curvedly narrowed behind, double the length of thorax, 

 slightly broader than it is at the base, with rounded shoulders ; no definite 

 dorsal sculpture can be seen, but behind the middle there are a few 

 irregular infuscate spots. 



Antennae about the same length as thorax, second joint hardly longer 

 than broad, third slender, distinctly longer than following ones, joints 6-8 

 small and bead-like, ninth transverse and slightly broader ; club abruptly 

 enlarged, basal joint transversely quadrate, the other subrotundate. 



N. crassulus (3405) is broader, the sides of the thorax are less flattened, 

 the discal impressions are deeper, and each elytron has a large nigrescent 

 mark.

Titirangi. One, from Mr. A. E. Brookes ; 21st November, 1914. 



Allobitoma gen. nov. 



Elongate, convex along the middle, the sides explanate. Antennae 

 ll-articulate, basal joint just visible above ; second stout, suboblong, fourth 

 and fifth shorter than third yet distinctly longer than broad, sixth shorter, 

 joints 7-9 moniliform ; club abruptly biarticulate, its basal joint thrice 

 the width of the ninth, the terminal not quite as broad, rather short, its 

 apex rounded. Epistome sinuate in front. Labrum transverse. Mandibles 

 bifid at extremity. Maxillary palpi thick, terminal joint subacuminate, not 

 at all securiform. Eyes small but distinct. Thorax lobate. Elytra elon- 

 gate-subcordate, with thick prolonged apices. Legs robust, tibiae without 

 apical spines. 



Prosternal process moderately broad, extending just behind the coxae. 

 Metasternum short, but little longer than the basal ventral segment, which 

 is rather longer than any of the following ones, fifth strongly rounded 

 behind. Epi|)l('urae broad. Antennal cavities deep, prolonged straight 

 backwards beyond but not encroaching on the eyes.
