410 COLEOPTERA. 



Underside sliinino; black, thickly clothed with depressed fiavescent scales 

 and coarse greyish setae ; nietasternuni medially impressed ; 5th segment 

 broadly rounded at the apex. 



Much narrower than P. dorsalis, the elytral base particularly, their 

 punctation less sharply defined, thorax longer, the rostral carina more 

 slender, &c. 



$. Length (rostrum inclusive), 9 mm. ; breadth, 3h mm. 



Moa Basin. Unique. Obtained from leaf-mould by Mr. T. Hall on the 

 20th October, 1913. 



Ohs. — In this and s(mie other species the interstitial nodosities near the 

 middle of the elytra are subject to variation : those on the left elytron only 

 are described. 



3878. Platyomida hystricula sp. nov. 



Opaque, fusco-piceous, antennae and tarsi fusco-rufous ; densely covered 

 with depressed infuscate and tawny squamae, and with longer paler ones 

 which are most conspicuous on top of the posterior declivity ; the legs bear 

 greyish outstanding setae ; surface rough and uneven. 



Rostrum a third shorter than thorax, slightly dilated anteriorly, its 

 slender carina much concealed by the squamae. Eyes slightly prominent. 

 Thorax slightly broader than long, more narrowed in front than behind ; 

 uneven, with some small obtuse tubercles ; the discal channel larger and 

 deeper in front than near the base, with broadly raised borders. Elytra 

 oblong-oval, almost thrice the length of thorax, scarcely any wider than it 

 is at the base, with curvedly narrowed shoulders, their sides with only a 

 single but only slightly prominent nodosity, placed behind each shoulder ; 

 the declivity narrowed but not usually vertical, with rough scales and 2 

 pairs of rather large nodosities ; the dorsum appears substriate, but in a 

 denuded specimen rather coarse oblong punctures are visible ; 3rd inter- 

 stices nodiform at the base, binodose near the middle, the terminal nodo- 

 sities moderately large but not overhanging the declivity ; 5th simple at 

 the base, binodose near the middle, not prominent behind. 



Underside, except the bare punctate mesosternum, thickly covered with 

 depressed yellowish and paler elongate scales ; 5th segment longer than 

 3rd and 4th, closely punctured, its apex truncate. 



Scape subclavate at the extremity, attaining the back of the eye ; 2nd 

 joint of funiculus slightly longer than 1st, joints 3-7 submoniliform, all 

 rather longer than broad. Tibiae fiexuous. 



A rather small rough-looking species, distinguishable by the rather large 

 subapical nodosities, the inconspicuous terminations of the 5th interstices, 

 and uneven thorax. The scrobes are well developed in front, but there is 

 a squamose space near each eye, and therefore nearly resemble those of 

 P. amota (1415). It should be located near P.hamiltoni (3264). 



Length (rostrum inclusive), 7|-8 mm. ; breadth, 2i--3-^ mm. 



Moa Basin : 20th October, 1913. Four individuals obtained by Mr. T.. 

 Hall fiom loaf-mould. 



3879. Platyomida sulcicollis sp. nov. 



Opaque, rathei- elongate ; piceous, antennae pitchy-red. tar.si fusco- 

 rufous : squamae principally cupreo-fuscous, fiavescent or tawny on the 

 head and rostrum, the sides of the thorax, and the shoulders, similarly 

 pale but more elongate on top of the declivity.
