OTIORHYNCHIDAE. 407 
is coarsely rugose. Elytra oblong, more than double the length of thorax, 
evidently wider than it is at the base, medially incurved there, with slightly 
narrowed, obtusely prominent shoulders, the declivity is curvate so that 
the extremity is somewhat inflexed ; the sutural pair of striae on each 
elytron are moderately coarsely and closely punctured ; 3rd interstices 
moderately elevated, somewhat prominent at the base, distinctly nodose on 
top of the declivity ; the 5th simple at the base, rather less elevated, and 
less distinctly nodiform behind, but prolonged, though not very obviously, 
half-way down the declivity; between these interstices the sculpture 
consists of irregular foveae, some extend right across the interval, there 
are only about 6 altogether; the lateral sculpture is not as coarse as the 
sutural; the suture is obtusely elevated behind. 
Smaller than H#. grisealis (3260), with nearly white clothing, the frontal 
thoracic depression and the elytral sculpture different. 
Length (rostrum inclusive), 64 mm. ; breadth, 22 mm. 
Oakden, near Mount Algidus. One found amongst a miscellaneous col- 
lection made by Mr. Roderick Urquhart and Mr. Hall on the 9th October, 
1913. 
3874. Platyomida dorsalis sp. nov. Platyomida White (syn. Himpaeotes 
Pascoe), Man. N.Z. Coleopt., p. 441. 
Robust, piceous, antennae and tarsi piceo-rufous ; densely covered with 
dull, small, depressed cupreo-fuscous squamae, and some longer flavescent 
ones on the rostrum, the head, and elytral nodosities. 
Rostrum as long as thorax, with a well-developed median carina. 
Thorax very slightly broader than long, very little wider before the middle 
than elsewhere, nearly straight behind, rather more narrowed in front; 
without rugae or tubercles, the broad central channel deeper in front than 
behind, the sides of the depression obtusely elevated. Scutellum small. 
Elytra a third broader than thorax at the base, nearly thrice its length, 
with simple apices, posterior declivity much narrowed and vertical, their 
sides uneven ; the sutural region is flat, each elytron has 6 dorsal series of 
distant, distinct yet moderately fine punctures, in each of which there is 
a small brassy scale; 3rd interstices elevated at the base and projecting 
slightly over the thorax, with a pair of oblong nodosities near the middle, 
and terminating in large horizontal prominences on top of the declivity ; 
5th plane at the base, moderately binodose behind the middle, their ter- 
minal nodosities not as thick as those of the 3rd but projecting obliquely 
outwards, each side underneath less distinctly trinodose ; the declivity has 
a pair of moderate nodosities just below the summit and another pair near 
the extremity ; these are the principal ones. 
Femora slender near the base; tibiae feebly flexuous, minutely denti- 
culate inwardly, with erect greyish setae ; posterior corbels with duplicate 
cilia and distinct outer truncature. Scape subclavate, setigerous, barely 
reaching the back of the eye. Second joint of the funiculus as long as the 
Ist, joints 3-7 gradually diminish ; club elongate-oval. Ocular lobes feebly 
developed. 
Underside nigrescent, with fulvescent and reddish scales and paler setae. 
Metasternum with a foveiform impression behind. Fifth ventral segment 
longer than 3rd and 4th combined, irregularly and closely punctured, much 
narrowed towards and distinctly emarginate at the extremity.
