A New Hawaiian Rhyncogonus (Coleoptera, Rhyncophora). 
BY DR. R. GC. L. PERKINS. 
(Presented by O. H. Swezey at the meeting of June 7, 1923.) 
Rhyncogonous saltus n. sp. 
Nearly black, though reddish in parts, the funicle joints of the 
antennae and the tarsi evidently rufescent. 
Head basally with distinet punctures, in front of. these strigose to 
about the line of the antennal insertions, sparsely clothed with pale yel- 
lowish setac; the eyes quite strongly convex; the first and second funicle 
joints of the antennae subequal, the first not three times as long as its 
greatest width, the third much shorter than these, the club longer than 
the three preceding joints together. 
Pronotum very densely, subrugosely punctured, such small spaces as 
are left between the punctures shining; a very narrow smooth median 
line, which in some aspects appears like a fine carina, extends prac- 
tically the whole length of the pronotum. The general clothing of this 
part is very sparse, but towards the sides it forms a dense band which 
is more or less interrupted or at least thinner towards the middle. 
Elytra narrow, about three times as long as the pronotum, and one 
and a half times as long as broad, clothed with pale decumbent setae 
(which do not form a pattern, being generally distributed) and with 
very sparse erect ones, which are chiefly noticeable on the apical and on 
the lateral parts; the coarse serial punctures are ill-defined or irregular 
in outline and between them are seattered minute turbereles or surface 
granulations; there are also some vague inequalities of the surface which 
are more or less transverse in direction, but, as happens in other species, 
there may be individual peculiarities. There is no distinct, sharp edge or 
carina marking off the pseudepipleural portion of the elytra, and this 
portion is well clothed in general, no distinct maculations being formed by 
the setae, though they are less numerous on the lower part. On the 
apical part of the femora the appressed setae become conspicuously dense, 
in the case of the front and middle legs on both the outer and inner 
surfaces, but only on the outer surface of the hind femora. The large 
basal portion of the abdominal ventral surface is mostly smooth and shin- 
ing, with copious and distinct punctures; the subtriangular apical seg- 
ment is very feebly sculptured but conspicuously pubescent, the two small 
preceding segments being comparatively bare. 
Female. Length 8 mm.; width of elytra about 3.5 mm. 
This obscure species is placed near FR. extraneus, simplex 
and vestitus, and bears considerable superficial resemblance to 
narrow and depauperated examples of simplex. Apart from
