316 COLKOPIKIIA 



(Iroup Byrriiidae. 



3741. Synorthus rectifrons sp. iiov. Synorthus Broun. Bullotin 2, N.Z. 



lust., p. 9, 1910. 



Convex, l)road. subovate, shining, witli distinct greyish-yellow, decum- 

 bent and suberect pul)escence dis{)()sed in different directions ; black, head 

 somewhat aeneous, legs and l)asal joint of antennae rufous, remaining joints, 

 palpi, and tarsi fulvescent. 



Head short and broad, moderately finely yet quite definitely and some- 

 what irregularly punctured ; the forehead subtruncate in the middle, oblique 

 and finely margined towards the eyes, which are moderately prominent in 

 front. Thorax not quite twice as broad as long, the sides finely margined 

 and "raduallv narrowed anteriorly, with subacute rectangular angles, its 

 surface moderately finely but not closely yjunctate. Scutellum absent. 

 Elvtra of the same width as thorax at the base, quite twice its length, 

 o-radually rounded posteriorly ; their punctation similar to that of the 

 thorax, but rather coarser on the middle of their basal half. 



Antennae very sparingly pubescent, 2nd joint stout yet evidently smaller 

 ■than the basal, 3rd slender and elongate, not quite as long as the following 

 three combined, 4th and 5th slightly longer than broad, 6th a little shorter, 

 7th broader than preceding ones, joints 8 10 about equally transverse, 

 broader than 7th, terminal as long as preceding two, the club therefore is 

 5-articulate. 



Tibiae finely setose, the posterior slightly arched, narrowed towards the 

 extremity, the anterior widened below the middle, somewhat obliquely 

 narrowed beyond, with short, quite lateral tarsal grooves, the apices minutely 

 bicalcarate ; tarsi normal. 



Underside nitid, piceous, slightly iridescent, the greyish-yellow pubes- 

 cence absent from the middle of the metasternum, which part is more 

 coarsely but less closely punctate than the rest of its surface. Prosternal 

 process broad, closely and finely punctured ; the coxae and femora rufescent. 



This must be located in Section III, near ^S. villosus, 1608, which, 

 however, is rather smaller, with obviously shorter and differently formed 

 antennae, more strongly curved tibiae, and more elongate outstanding elytral 

 vestiture. S. versipilus, 3562, is smaller, and belongs to Section IV. 



Length, 3| mm. ; breadth, 2| mm. 



Mount Hutt. Unique as yet ; found on the 25th January, 1913, by 

 Mr. T. Hall. 



3742. Pedilophorus nigrescens sp. no v. Pedilophorus Steffahny, Man. 



N.Z. Coleopt., 244 (syn. Morychis). 



Convex, oval, widest ])ehind the shoulders, considerably attenuate pos- 

 teriorly, shining ; bronzed-black, legs and basal joint of antennae rufous, 

 remaining joints of the latter, the tarsi, and palpi more or less fiavescent. 



Head distinctly and rather distantly })unctured, more closely near the 

 eyes, nearly smooth on the middle ; forehead slightly medially rounded, 

 indistinctly marginate towards the eyes. Thorax twice as broad as long, 

 its sides finely margined and parallel but gradually narrowed towards the 

 deflexed, acutely prominent anterior angles, posterior angles rectangular ; 

 distinctly, irregularly, and remotely punctate. Elytra thrice the length of 

 thorax, of the same width at the base, widest before the middle, much but 

 giadually narrowed towards the extremity, with fine coriaceous sculpture.
