T 8 COLEOPTERA 



The insect more nearly resembles D. subopaca than D. aterrima ; 

 and one of my two specimens has brown elytra, but this, I suspect, is 

 owing^to its having been immature. 



Length, 2\ lines. 



I have only seen the two specimens which I found some years ago 

 at "Auckland. 



40. D. maura, n.s. Oblong, scarcely depressed ; moderately 

 shining, pitchy-black, tibise and elytral margins more or less rufescent, 

 the tarsi, antennae and palpi ferruginous, epistome infuscate. Head 

 moderate, much smaller than the thorax, rather smooth, with not at all 

 prominent eyes. Prothorax. sub-cordate, moderately large, transversal, 

 slightly convex, regularly rounded laterally but more narrowed poste- 

 riorly than in front, with obsolete posterior angles ; its surface presents 

 an even slope towards the lateral margins, which are not at all expla- 

 nated or reflexed, a fine dorsal line with a frontal depression, an elon- 

 gate, irregular impression midway between it and each side not attaining 

 the apex, and many transverse striolse. Elytra oblong-oval, slightly 

 convex, a little broader than the thorax, only slightly sinuate and not 

 truncate posteriorly, and with very slightly produced apices ; each bears 

 a scutellar and eight well-defined, apparently impunctate striae, between 

 the outer stria and reflexed margin a row of punctiform impressions, 

 and on the third interstice a median and apical puncture. 



The 4 legs and antennae are slender. The apical joint of the maxil- 

 lary palpi longer than the penultimate. 



The form of the prothorax readily distinguishes this species. 



Length, 4 lines ; breadth, i \. 



I found one at Parua, near Whangarei Harbour. 



Group ANCHOMENID^E. 



Ligula free at its extremity. Mentum normally emarginated. Legs 

 more or less long and slender ; the anterior tibiae not at all, or only 

 feebly, dilated towards the apex. The three first joints of the front 

 tarsi dilated in the males, triangular or quadrate, nearly always longer 

 than broad ; their soles squamulose. Tarsal claws simple or dentate. 



Calathus. 



Bonelli ; Lacord.Hist. des Ins. Coleop., Tom. i,/. 342. 



Mentum, large, deeply hollowed, furnished with a strong, bifid 

 median tooth. Ligula a little narrowed in the middle, slightly rounded 

 in front. Last joint of the palpi sub-cylindrical, and truncated at the 

 end. Mandibles a little prominent, feebly arched, sharp. Labrum 

 transversal, entire. Head oval, slightly narrowed behind. Eyes rather 

 large, a little prominent. Antenna filiform, as long as the body ; first 

 joint stout, cylindrical ; second short ; third a little longer than the 

 following ones, which are about equal. Prothorax nearly always longer
