OTIORHYNCHIDAE. 409 



3876. Platyomida fuscella sp. iiov. 



Stout, opaque, piceous, autennao piceo-rufous ; covered witli tawny 

 depressed anJ a few setiform squamae. 



Rostrum a little expanded anteriorly, a third shorter than thorax, with 

 a median ridge which does not extend more than half-way towards the 

 front and ends in an elongate interocular impression, the apex finely rugose- 

 punctate. Thorax a little dilated before the middle, more naiTowed in 

 front than behind, without perceptible rugae or punctures ; discal channel 

 medially interrupted, rather broader and deeper in front than behind ; its 

 length rather less than the breadth. Elytra nearly thrice the length of 

 thorax, almost double its width in the middle, with curvedly narrowed 

 should(>rs, so that the true base hardly exceeds that of the thorax, their 

 sides slightly uneven, gently narrowed behind the middle, more abruptly 

 at the declivity, which is vertical ; each elytron has 6 series of dorsal, 

 moderate punctures ; 3rd interstices shghtly porrect and obtusely elevated 

 at the base, indistinctly raised behind the middle, terminating as large 

 horizontal nodosities on top of the declivity ; 5th moderately binodose 

 behind the middle, terminal nodosities less prominent than those of the 

 3rd and directed backwards ; the declivity with 2 pairs of small nodosities, 

 the upper larger and nearer to each other than the lower. 



Antennae finely setose, 6th and 7th joints of funiculus obconical, hardly 

 longer than broad, shorter tlian those of P. dorsalis. Tibiae denticulate 

 inwardly. 



Underside nigrescent, with brassy scales and setae. Fifth ventral seg- 

 ment closely and rugosely punctured, much longer than 3rd and 4th, its 

 apex broadly rounded. 



The shorter rostrum, its broad abbreviated ridge, the distinct inter- 

 ocular impression, rounded humeral angles, less flattened dorsum, &c., 

 differentiate it. 



?. Length (rostrum inclusive), 11 mm. ; breadth, 4| mm. 



Routeburn. Unique. Found by Mr. T. Hall on the") 3th February. 1914. 



3877. Platyomida rectirostris sp. nov. 



Opaque, piceous, antennae and tarsi rufo-piceous ; densely covered -with 

 small, depressed, obscure coppery, and more setiform paler squamae. 



Rostrum parallel, almost as long as thorax, with a fine but di.stinct 

 median carina. Thorax cylindric, apparently elongate, really of equal 

 length and breadth, only shghtly dilated before the middle ; disc without 

 rugae or tubercles, its central channel broad, rather deep, and almost unin- 

 terrupted from base to apex, with obtusely raised borders, near each side 

 behind the middle there is a transverse impression, no punctation is visible. 

 Scutellum small. Elytra oblong-oval, their sides somewhat uneven, gradu- 

 ally narrowed towards the base, which is a little and irregularly incurved 

 and but little broader than that of the thorax ; they are more than double 

 its length, narrowed and vertical behind ; they are nioderately distinctly 

 and somewhat irregularly seriate-punctate ; 3rd interstices elevated at the 

 base, trinodose along the middle, and ending in large, nearly horizontal 

 protuberances on top of the posterior declivity ; 5th binodose behind the 

 middle, the terminal nodosity rather smaller than that of the 3rd and 

 extending obliquely outwards ; declivity with a pair of smaller nodosities 

 near the summit, and another pair near the extremity. 



Antennae similar to those of P. dorsalis ; legs rather long and slender.
