102 Tratisoctions. 



the vertical declivity, and there tipped with short grey setae ; the serial 

 punctures are rather indefinite, but the rows of pale squamae are distinct, 

 and there are some small black granules on the basal half ; on the 

 3rd interstices there is a basal nodifonn elevation and a smaller one in line 

 with the posterior femora ; there are 2 others near each side before the 

 middle ; the declivity is a good deal narrowed, its sides are darker than 

 the suture, with some well-marked punctures ; along the fuscous vertical 

 sides of the hind-body the puuctation is seriate and moderately coarse. 



This is the largest member of the genus as yet known. The most 

 similar species is L. virilis (2867), which may be easily separated by the 

 trinodose elytral interstices, the thicker and quite straight scape, and more 

 prominent sides of the thorax, just before the middle. 



Length (rostrum inclusive), 11mm. ; breadth, 5|mm. 



Erua. One example only, found amongst decaying leaves in January, 

 1910, by Mr. W. J. Guinness and myself. It bears that gentleman's name. 



3267. Lyperobates elegantulus sp. nov. 



Piceous, closely and uniformly clothed with small depressed fulvescent 

 squamae ; tarsi and antennae rufo-piceous. 



Rostrum with an obtuse median carina and a broad groove along each 

 side of it, slightly shorter than thorax ; interocular fovea elongate. 

 Thorax subcylindrical, a little longer than broad, slightly dilated and 

 broadly rounded, but not at all prominent, before the middle, very gently 

 curvedly narrowed anteriorly, nearly straight behind ; its surface a little 

 uneven, with 4 shallow frontal and 2 basal impressions, its central portion 

 irregularly and longitudinally but only obtusely elevated, and with some 

 small black granules there. Scutellum with very slender fulvous setae. 

 Elytra slightly broader than thorax at the base, shoulders oblique ; just 

 behind each of these there is an outstanding, elongate, lateral tubercle ; 

 in line with these the breadth is double that of the widest part of the 

 thorax ; the sides are widely incurved towards the horizontal lateral 

 protuberances, which project backwards beyond the subtruncate summit 

 of the nearly vertical posterior declivity, and extend outwardly very nearly 

 as far as the humeral tubercles ; the dorsum is almost flat, and bears on 

 each elytron 4 small well-defined grey-tipped tubercles, which are placed 

 before the middle ; the 3rd interstices are nodiform at the base ; the serial 

 punctures on the disc are moderately fine and distant, those on the fuscous 

 somewhat inflexed sides are rather coarser. 



Scape slightly flexuous, very gradually incrassate ; 2nd joint of funi- 

 culus rather longer than the basal ; club elongate-oval, its intermediate 

 joint slightly narrowed towards the base and consequently distinctly marked 

 off from the 1st. 



Underside nigrescent, with slender bright coppery squamae. Meta- 

 sternum with a deep median pimcture. Basal ventral segment slightly 

 impressed along the middle, subtruncate between the coxae, not quite twice 

 the length of the 2nd. 



The subcylindric thorax, nearly quite level elytral disc, the elongate 

 humeral tubercles, and posteriorly prolonged subapical protuberances are 

 distinctive characteristics. The nearest species are L. virilis and L. 

 guinnessi. 



Length (rostrum inclusive), 10 mm.; breadth (maximum), 4|^mm. 



Erua. Unique. Picked out of leaf-mould forwarded to me by Mr. 

 W. J. Guinness in April, 1910.
