GALERUCIDAE. 471 
The thoracic punctation is similar to that of L. dilucidus; 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 elongate and 
slender; it is, therefore, independently of general appearance, essentially 
different. 
Length, 5mm.; breadth, 2 mm. 
Moa Basin. One; another of Mr. Hall’s discoveries on the 20th 
October, 1913. Var. (one): Sides of thorax almost regularly 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, 42 mm.; breadth, 1? 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 extremity, apices 
apparently narrow, oblique near the suture, rounded externally ; 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 palez. 
Length, 3} mm.; breadth, 14 mm. 
Moa Basin. Another species from Mr. Hall; one example only.
