882 COLEOPTERA 



shoulders, their apices individually rounded; lateral rims distinct, 

 ending just before the apices ; their striae, seemingly impunctate, are 

 tolerably well marked on the disc, but become less evident at the 

 sides and apex ; third interstices more or less obviously tripunctate ; 

 their whole surface covered with a multitude of minute brassy 

 impressions. Legs robust ; the two basal articulations of the anterior 

 tarsi of the male strongly expanded and somewhat produced inwardly, 

 particularly the second ; the first armed outwardly with two or three 

 spiniform denticles, the third also a little produced. Underside 

 testaceous, the apex of terminal segment of abdomen infuscate, the 

 rest dark smoky-brown. 



Smaller than C. albescens ; the elytral apices not at all truncate, 

 and the rims less explanate and less abruptly marked off at the 

 extremity. 



Length, if-2 lines; breadth, f |. 



Named in honour of its discoverer, Mr. Thomas Chalmers, who 

 pointed it out on the sandspit at Port Chalmers. 



Group PERICALID^E. 



Scopodes (P. 67). 



1569. S. bryophilus, n.s. Cupreous, shining, legs and basal 

 joints of antennae greenish-black ; moderately elongate. 



Head with fine longitudinal striolse behind, and two frontal 

 (interocular) punctures; labrum much rounded, bluish; eyes pro- 

 minent; the whole surface more or less metallic-green. Prothorax 

 rather longer than broad, cordiform, broadest before the middle, 

 where it is rounded but not angulated, from thence it is narrowed, 

 and again dilated and obtusely angulated at the base ; the lateral 

 rims distinct, bent inwards after forming the posterior angles, but 

 before reaching the true base ; disc with transverse striolse, almost 

 smooth behind, with a very distinct median groove. Elytra mode- 

 rately long, apices obliquely truncated ; their sculpture consists of 

 tolerably distinct, impunctate striae, the foveas are small but con- 

 spicuous, and, like the margins, tinged with green, their surface, as 

 well as that of the thorax, being of a reddish- coppery hue. 



The whole surface of the body being densely and minutely 

 sculptured causes the insect to seem less glossy than it would be 

 otherwise. 



The general outline is similar to that of S. versicolor, but the 

 expanded hind angles of the thorax at once differentiate it from that 

 species.

A specimen of this pretty beetle was detected by Mr. S. W. Fulton 

 on Mount Maungatua, amongst Sphagnum moss. 



I57 - S. COgnatUS, n.s. Concolorous, black, not very glossy; 

 rather broad, slightly convex. 



Head with longitudinal strigae ; eyes large and prominent. Pro- 

 thorax transversal, cordate, widest before the middle, where it is 

 angulated, from that point gradually narrowed behind ; lateral
