GALERUCIDAE. 471 



The tlioracvc punctatioii is similar to that of L. dilucidii.s ; this species 

 has a basal impression near each shoulder but none at all alongside the 

 suture, its eyes are more prominent, the antennae are more elonj^ate and 

 slender ; it is, therefore. inde])endently of general appeai'ance, essentially 

 different. 



Length, 5 mm. ; breadth, 2 mm. 



Moa Basin. One; another of Mr. Hall's discovei-ies on the 20th 

 October, 1913. Var. (one) : Sides of thorax almost icgularly curved, but 

 without lateral elevations. 



3973. Luperus gracilipes sp. nov. 



Nitid, dark cyaneous, legs and antennae fuscous. 



Head, including the large prominent eyes, not appreciably narrower 

 than the widest part of thorax, smooth behind, the forehead nigrescent, 

 with a few ashy hairs. Thorax a third broader than long, somewhat wider 

 at the middle than elsewhere, a little narrowed towards the front and base, 

 the latter very slightly curved near the sides, with obtuse angles, lateral 

 rims well developed ; discal punctation minute and obsolete before the 

 middle, more distinct, irregular, and unequal near the base and sides, 

 broadly impressed near the anterior angles. Scutellum subtriangular, 

 small. Elytra broader than thorax at the base, four times its length, apices 

 broadly rounded ; they are moderately closely and distinctly but not 

 coarsely punctured, with smooth intervals, more finely near the shoulders, 

 where they are broadly but not deeply impressed. 



Antennae pubescent throughout, filiform and slender, extending beyond 

 the hind thighs. 



Legs long and slender, tibiae straight, basal joint of posterior tarsi 

 nearly double the length of the 2nd. 



The large and prominent eyes, the frontal thoracic impressions, the 

 slender antennae and long legs, in conjunction, render this species distinct. 

 The thoracic sculpture is similar to that of L. cyanescens. 



Length, 4f mm. ; breadth, If mm. 



Moa Basin. Unique. From Mr. Hall ; 20th October. 1914. 



3974. Luperus minor sp. nov. 



Elongate, slender, shining ; dark cyaneous. head aeneous, legs pale 

 fuscous, antennae darker. 



Thorax a third broader than long, its sides rather finely margined, nearly 

 straight, a little narrowed behind, anterior and posterior angles subrect- 

 angular ; the surface very minutely and closely sculptured on some parts. 

 Elytra with obtusely prominent shoulders, rather wider at the base than 

 the thorax, nearly five times its length, dehiscent near the extremitv. apices 

 apparently narrow, oblique near the suture, rounded externallv ; moderately 

 finely and closely punctate, with an elongate impression near each shoulder, 

 the punctures more distant there. 



Though nearly allied to L. gracilipes this species is much smaller, the 

 head is nearly as broad as the thorax but the eyes are less prominent, the 

 thorax is rather smaller and is only indistinctly sculptured anywhere, the 

 elytral apices are very different, the shoulders appear to extend a little 

 forwards, the antennae and legs are nearly equally elongate but the latter 

 are paler. 



Length, 3| mm. ; breadth, Ijmm. 



Moa Basin. Another species from Mr. Hall ; one example only.
