1040 COLEOPTEKA 



elongate. Thorax transverse, sides strongly rounded in front, 

 sinuously narrowed behind ; basal angles rectangular ; the surface 

 finely punctate, its two dorsal impressions well marked and extend- 

 ing forwards to beyond the middle, each side also impressed. Scu- 

 tellum smooth. Elytra somewhat longer than broad, parallel, 

 slightly wider than thorax, apices nearly truncate ; finely and 

 closely punctured, feebly impressed near the base. Hind-body as 

 wide as elytra, twice their length, not flat, lateral margins nearly 

 plane, there being only a linear depression to distinguish them from 

 the middle part, finely punctate. Tibice simple, the intermediate 

 rather short. 



In some respects like 0. sagoloida, altogether narrower, colour 

 different, elytral sculpture not obsolete behind. 



Length, 1^ lines ; breadth, nearly ^ line. 



Taieri, Otago. One specimen, from Mr. S. W. Fulton. 



1861. O. Stenosoma, '^-s- Elongate, narrow, parallel, sub- 

 depressed, shining, clothed with distinct yellow hairs ; chestnut-red, 

 with slight variations, tarsi and palpi yellow, legs rather darker, 

 antennas fulvescent. 



Head, somewhat rounded, finely punctured, the space between 

 the frontal impressions nearly smooth. Paljn with the terminal 

 joint elongate and narrow. Antenna elongate, the last six joints 

 larger than the preceding ones, each broader than long. Thorax 

 rather broader than long, widest near the front ; its sides finely 

 margined, strongly rounded, much narrowed behind, basal angles 

 rectangular ; its punctuation rather more distinct than that of the 

 head ; it has two broad dorsal depressions which extend nearly to 

 the apex, and one at each side behind the middle. Elytra oblong, 

 distinctly and regularly punctured, not striate, with an elongate 

 depression at each side of the suture, apex truncate. Hind-body 

 very much longer than the elytra, parallel, not depressed, broadly 

 margined, very finely punctured. Tibice simple ; the four basal 

 joints of the tarsi shorter than the apical one. 



Length, 1^ lines ; breadth, |- line. 



Mount Cook. One specimen, sent by Mr. H. Suter. 



Ischnoderus. 



1862. I. pictulus, '^-s- Depressed, very elongate, parallel, 

 shining; head rufo-piceous, frontal portion paler; thorax fulvescent, 

 dark along the middle ; elytra testaceous, suffused with a blackish 

 colour behind ; hind-body not so pale as basal portion of elytra, 

 second, third, and fourth segments with a fuscous patch near each 

 side, the fifth with a transverse band of the same colour; legs 

 fulvescent ; six last joints of antennae opaque, densely pubescent, 

 fuscous, the others reddish. 



This species most nearly resembles 1. gcnalis (No. 220) ; the head 

 is shorter behind the eyes and altogether smaller. Thorax more 

 transversal and more graduallv narrowed behind. Elytra smaller.
