Broun. — New Genera and Species of Coleoptera. 153 



Obs. — Since the above description was written a male specimen has 

 been received from Mr. O'Connor. 



Male. — Thorax longer than broad, oviform, with minute lateral 

 tubercles, a median and frontal ; its surface finely and closely punctured, 

 with, near each side, an elongate slightly raised space bordered by coarser 

 punctures ; and another smooth linear area behind the middle. The 

 7th joint of the antennae extends beyond the extremity of the hind-body. 



3342. Didymocantha oedemera sp. nov. 



Subdepressed, elongate ; head and thorax opaque, fuscous ; elytra 

 nitid, also fuscous, but with the following testaceous marks : 1st lateral, 

 situated behind the shoulder, oblong ; 2nd large, elongate at the side, and 

 curved inwards and backwards, but not reaching the suture ; 3rd much 

 shorter than the 2nd at the side, extending obliquely forwards and as far 

 inwards as, but not touching, the 2nd ; 4th apical, almost in contact with 

 the suture : base of the femora and upper half of the tibiae testaceous, 

 their other portions rufo-fuscous ; antennae and tarsi infuscate red ; spar- 

 ingly clothed with erect, rather elongate, yellowish hairs. 



Head vertical and obscurely rufescent in front, distinctly and closely 

 punctate. Thorax of about equal length and breadth, its sides moderately 

 rounded, and a good deal narrowed near the base ; disc nearly plane, closely 

 punctured, the basal sculpture granular or transversely rugose ; it is entirely 

 destitute of lateral or discoidal prominences. Scutellum densely and very 

 minutely sculptured, almost nude. Elytra broader at the base than the 

 middle of the thorax, more than thrice its length, with strongly singly rounded 

 apices ; their surface fiat, closely and distinctly punctured at the base, 

 the punctures becoming more distant and shallow towards the extremity, 

 but not obliterated even there. 



Antennae finely pubescent, and bearing some longer hairs near the base, 

 they just reach the extremity of the body, their 4th joint quite half the 

 length of the 5th, which is slightly longer than the 3rd. Femora extremely 

 slender and stalk-like basally for half their length, but very strongly clavate, 

 the middle pair almost bulbous, near the extremity ; intermediate tibiae 

 distinctly curvate. 



This species stands alone, owing to the very remarkable structure of the 

 thighs and the total absence of inequalities on the thorax. 



Length, 7|mm. ; breadth. 2 mm. 



Clevedon, near Auckland. The unique specimen was captured by a 

 lad, William Home, of Devonport. 



3343. Didymocantha fuscicollis sp. nov. 



Elongate, slightly nitid, very scantily clothed with elongate slender 

 greyish hairs ; head and thorax rufo-fuscous, elytra infuscate testaceous, 

 the suture and scutellum nigrescent, legs and antennae pale testaceous, 

 but with the basal joint of these latter rufescent. 



Head distinctly and closely punctate, finely sulcate along the middle, 

 its sides, in front of the eyes, acutely prominent. Thorax of about equal 

 length and breadth, its sides not evenly rounded, there being a distinct 

 median tubercle and a very slight prominence near the front ; it is 

 irregularly puncture:!, very coarsely and rugosely at the sides, closely 

 and rather coarsely on the disc, more finely at the base ; there is a 

 slightly raised median line, and another, but shorter one, between it 

 and each side ; near the front there is a pair of rounded, but not smooth.
