282 Major T. Broiin on neio Genera and 



tions ; there are two more on the summit of the hind slope, 

 but further from the suture than tlie middle pair ; lower 

 down tliere is atiothrr pair, almost united to an elonjiated 

 elevation on eacli elytron, near the apex ; the derm is glossy 

 brown on the disk, but near the hind slope appears greyish, 

 owing to the fine pubescence there ; immediately behind this 

 the pubescence is dark, but the lower part of the declivity 

 and tlie sides are mottled with grey and ash-coloured 

 pubescence. 



Femora clavate, fuscous ; pubescence grey ; tibiae yellow, 

 but fuscous near the base. 



This should be placed near S. costifer (2272), which is 

 considerably larger, and bears on each elytron a costa which 

 extends from the middle and is bent at the base, so as to 

 join the raised and thickened suture.

Hokianga. One found at Oponoui, when accompanied by 

 Mr. John "Webster, in whose honour it is named. This 

 distinction is conferred so as to place on record the name of 

 one of those courageous northern pioneer settlers who are 

 now fast passing away. 



Somatidia heterartha, sp. n. 



Small, slightly shining ; piceous ; antennae and legs 

 rufescent, not variegated ; tarsi testaceous ; sparingly clothed 

 •with slender but quite perceptible greyish pubescence; the 

 hinder pairs of tibiae along the outer face more coarsely 

 pilose and darker ; the intermediate pair more evidently 

 emarginate than the posterior. 



Head moderately convex, its deflexed forehead abruptly 

 truncate in front. Thorax widest before the middle, where 

 it is rounded, considerably narrowed behind, with a minute 

 spine at each side behind the middle ; the surface rather 

 coarsely punctate, but without inequalities. Elytra mode- 

 rately convex, less coarsely punctured than the thorax, the 

 sutural region and apex more finely and distantly. 



Antenna stout, reaching backwards to the top of posterior 

 declivity ; basal joint stout, second small and subquadrate, 

 third about as long as the following three or four conjointly, 

 fourth unusuall}' abbreviated, but little longer than broad ; 

 remaining joints just oblong. 



The small size, unicolorous body, and remarkable antennae 

 differentiate this from previously described species. 



Female less coarsely sculptured and rather dull.
