156 Transact ions. 



marked with ligLt fuscous, wliich colour extends backwards, but less de- 

 finitely, near the sides, and becomes spotted with grey pubescence near the 

 apex ; the enclosed central space is pale and somewhat maculate, it is dis- 

 tinctly but not closely punctured, and bears some dark erect setae ; on each 

 elytron there are 2 small elevations or crests, the first before the middle, 

 the other at the simmit of the hind slope. 



This species is more robust than S. nodularia, and differs from it in the 

 broad interantennal space, dift'erent vestiture, sculpture, and coloration, 

 the less basally narrowed thorax, and the very broad process between the 

 intermediate coxae. 



Length, 6^ mm. ; bi-eadth, 2|^ mm. 



Erua. The unique specimen was found amongst some leaf-mould col- 

 lected and forwarded to me by Mr. \N . J. Guinness in March, 1910. 



3347. Somatidia posticalis sp. nov. 



Subopaque, fusco-niger, with an irregular, more or less maculate, area 

 between the hind thighs covered with grey pubescence, the whole of the 

 dark hind slope spotted with grey ; tarsi and tibiae flavescent, the latter 

 with a small subapical spot and their basal half fuscous : antennae with the 

 basal joints fusco-rufous and feebly speckled, the remainder testaceous 

 at the base but fuscous beyond it. 



Head densely covered with yellowish pubescence in front, and with 

 a few small but distinct punctures, the interocular space broad and quite 

 black. Thorax slightly broader than long, widest before the middle, mode- 

 rately narrowed backwards ; the disc irregularly, moderately, but not 

 closely punctured, and with a broad median impression. Scutellum greyish. 

 Elytra of the same width as thorax at the base, more than twice its length, 

 gradually dilated towards the middle ; they are irregularly but not coarsely 

 punctate ; on each there are three small specks of brassy pubescence, and 

 there are also a few erect setae on the hind slope. 



Antennae not quite reaching the extremity of the body, their 4th joint 

 shorter than the 3rd, but longer than the 5th. 



An easily identified species, owing chiefly to the almost uniformly 

 nigrescent and mottled surface. The thorax, before the middle, at each 

 side of the central impression is convex, so that its frontal portion seems 

 a little depressed. There is a fine line along the back of the head. The 

 labrum is reddish, with elongate flavescent setae. There is no trace of the 

 scutiform mark on the hind slope seen in S. avtarctica and its allies. 



Length, 6| mm. ; breadth, 2| mm. 



Wairiri, Kaikoura Range. My specimen was found by Mr. W. L. 

 Wallace. 



3348. Somatidia corticola sp. nov. 



Subopaque, rather broad, moderately convex; dark fuscous, tibiae 

 and tarsi obscure testaceous, sometimes quite infuscate ; antennae also 

 variable; fusco-rufous, or much darker, and mottled with greyish pubescence ; 

 the body with yellowish-grey pubescence and some erect setae, but the 

 humeral region, a broad irregular fascia behind the posterior femora, and 

 a much interrupted but not scutiform subapical area are dark fuscous. 



Head distinctly and moderately closely punctured, broad and unim- 

 pressed between the antennary orbits. Thorax rather broader than long, 

 wader before the middle than elsewhere, rather closely and coarsely punctate ;
