430 COLEOPTERA. 
3907. Rachidiscodes altipennis sp. noy. 
Nitid, nearly glabrous, having only a few yellowish scales on the thorax 
and between the eyes; piceous, elytra rufescent along the middle, antennae 
and legs light castaneous. 
Rostrum smooth in front, bisuleate behind, and with an additional 
lateral stria that might be mistaken for the scrobe. Thorax a third longer 
than broad, widest at the middle; its sculpture consists of moderate 
punctures and obtusely elevated intervals. Elytra not double the length 
of thorax, strongly arched and on a higher plane than it is, rounded, widest, 
and most convex behind the middle, and becoming very narrow at the 
extremity ; on each elytron there are 4 rather broad, deep, apparently 
impunctate dorsal striae, those along the sides are less distinct ; interstices 
convex, the pair near the suture are convex from base to apex, the 3rd 
becomes indefinite near the base, the 4th behind. 
$. Length (rostrum exclusive), 24mm.; breadth, 1 mm. 
Hollyford; 18th February, 1914. Described from a single male found 
by Mr. T. Hall amongst fallen leaves. 
Allaorops gen. nov. 
Minute, convex, glabrous. Rostrum arched, stout, as long as thorax. 
Scrobes open above, dilated between the middle and apex, obliquely pro- 
longed underneath. Eyes small, depressed, indistinct, lateral, their distance 
from the thoracic apex equals their own length. Thorax without ocular 
lobes, as long as broad, oviform, base and apex truncate. Scutellum 
absent. Elytra only a third longer than thorax, as broad as it is, and 
slightly emarginate, at the base, subovate, strongly arched and subvertical 
behind. 
Scape stout, gradually incrassate, inserted between the middle and apex 
and reaching the front of the eye. Funiculus 7-articulate, 2nd joint oblong, 
as long as the basal, the others successively incrassate, transverse. Club 
oblong-oval. , 
Femora elongate, simple. ‘Tibiae straight, also long, indistinctly 
mucronate. Tarsi rather short, intermediate joints transverse, penultimate 
not at all expanded, excavate above near the apex only; terminal 
nearly as broad and as long as the preceding two united, with minute 
curved claws. 
Prosternum elongate, emarginate in front, coxae large, prominent, and 
contiguous, situated in the middle. Metasternum short. Abdomen 
elongate, basal segment rounded between the widely separated coxae, twice 
the length of the next in the middle, its hind suture distinct and almost 
straight, 5th longer than the deeply divided short 3rd and 4th together, 
transv ersely quadrate, finely marginate, medially emarginate at apex. 
Resembles Allaorus in contour, structurally more nearly allied to 
Rachidiscus, but easily separable therefrom by the rostrum being 
subpterygiate before the middle, by the smal! distant eyes, considerably 
less medially narrowed body, different tarsi, &c. 
3908. Allaorops carinatus sp. noy. 
Nitid, oblong, slightly narrowed towards the middle, glabrous; nigro- 
piceous, legs pitchy-red, antennae and tarsi fusco-rufous.
