LAMIIDAE. 459 



is largest at the side and nearly reaches the suture ; the lower part of the 

 shoulders and basal half of the sides of thorax are also fuscous ; antennae 

 and legs fusco-testaceous, the former with the tips of joints 4-11 infuscate, 

 tibiae with rather small spots ; pubescence depressed, distinct, of a tawny 

 grey on the lighter parts and forming spots on the posterior declivity. 



Head distinctly and broadly concave between the antennae, without 

 perceptible punctation. Thorax of equal length and breadth, its sides 

 gently rounded ; disc moderately finely, distantly, and irregularly punctate, 

 with a pair of small median nodosities, and a broad but not conspicuous 

 swelling at each side behind the middle. Scutellum broadly triangular. 

 Elytra widest at the middle, where they are a fourth broader than the 

 thorax, but only very slightly wider than it is at the base, twice its length, 

 gradually declivous behind ; the suture along the basal half is obtusely 

 elevated, near the middle of this part, on each, there is a slight elongate 

 elevation which is fuscous in the centre, in line with this, on the top of the 

 declivity, there is another ; their punctation is moderately coarse and 

 irregular. 



Antennae as long as the body, the infuscate 3rd joint just reaches the 

 shoulder, the 4th is shorter than 3rd but evidently longer than 5th. 



This somewhat resembles S. picticornis (2994), from Invercargill, which 

 measures 4| mm. by 2 mm., and has a narrower head ; its thorax is coarsely 

 and closely punctured in front and has neither discal not lateral nodosities, 

 its scutellum is more elongate, the elytral suture is perfectly flat, and the 

 vestiture is rather finer. 



Length, 5| mm. ; breadth, 2 mm. 



Eveline Glacier, beyond Routeburn. Mr. T. Hall scraped a specimen 

 ofi a tree covered with moss and lichen, at a height of 3,000 ft., on the 

 14th February, 1914. 



Obs. — The following varieties of 2994 occur in adjacent localities, all 

 but one represented by single individuals in Mr. Hall's collections. 



Var. A. — Mount Alfred. 4 mm. by If mm. Thorax widest and broadly 

 rounded before the middle, coarsely and closely punctured in front. Elytra 

 without median crests or spots, but with a slight elevation along the middle 

 of the basal half of each. Male. 



Var. B. — Ben Lomond. 4^ mm. by 2 mm. Fem. Coloration more 

 dusky throughout. Head broader between the antennae. Thorax with a 

 pair of small median nodosities, frontal punctation very coarse. Elytra 

 almost entirely maculate, without any posterior dark area, but with a pair 

 of minute crests on the summit of hind slope in addition to the median 

 ones. 



Var. C. — Routeburn. 4|mm. by 2 mm. Antennae almost immacu- 

 late, their 4th joint a third longer than 5th. 



3951. Somatidia obesula sp. nov. 



Broad, moderately convex, thorax and elytra narrowed and of the same 

 width at their junction, without crests or elevations, nitid ; dorsum dark 

 fusco-rufous, sides of thorax and elytra dark fuscous, as are also the humeral 

 region, the interrupted fascia across the top of the posterior declivity, and 

 its middle portion ; it is irregularly clothed with depressed fulvescent hairs, 

 and moderately elongate erect setae. 



Head as broad as thoracic apex, distantly punctate. Thorax a third 

 broader than long, rather strongly rounded and widest just before the
