Mr. F. P. Pascoe on new Species of Rhynchites. 391 
XLVIIL.—Deseriptions of some new Asiatic Species of 
Rhynchites. By Francis P. Pascog, F.L.S. &e. 
Ir is chiefly from the collection made by Mr. Wallace that I 
have selected the following well-marked species of Rhynchites. 
The genus was separated from Attelabus, Linn., by Herbst in 
1797, and comprises about 100 species, including those here 
described ; it 1s almost cosmopolitan, but has not yet been 
found in Australia. M. Roelofs has lately described several 
new species from Japan; and I have here added another 
(allied to R. betulet?) which is also found there (Yokohama), 
although it does not seem to have been met with by Mr. 
Lewis’s collectors. 
Ehynchites elystus. 
Lt. lete ceeruleus, sparse albido-pilosus ; rostro ( Q ) corporis dimidia 
longitudine, modice arcuato, vage punctulato, dimidio basali tri- 
carinulato ; ( ¢ ) breviore et manifeste crassiore, infra angulis ex- 
terioribus utrinque fortiter quinquedentatis ; antennis haud elon- 
gatis, articulis 3°, 4° sequalibus ; clava magna, grisea, art. duobus 
basalibus triangularibus, singulis latitudine haud longioribus, ul- 
timo ovato, acuminato ; prothorace latitudine haud longiore, sat 
vage punctulato; elytris amplis, striato-punctatis, punctis ap- 
proximatis, interstitiis sat confertim punctulatis ; tibiis costulatis. 
Long. 4 lin. ; 
Hab. Sumatra. 
Allied to two species known as L. philippensis, Chev., and 
hk. celestinus*, Gyll., but at once distinguished from both by 
the sparse punctuation on the prothorax. &. azureus, Ol.t, isa 
very distinct species, hitherto overlooked, except that it is 
doubtfully cited as a synonym by Gyllenhal for his calestinus. 
Ethynchites aleyoneus. 
R, ceruleus, elytris violaceis, albido-pilosus ; rostro tenui, corporis 
longitudine vix dimidia, modice arcuato, haud carinulato, basi inter 
oculos compresso ; antennis haud elongatis, articulo tertio quam 
quarto paulo longiore, clava concolori, art. duobus basalibus elon- 
gato-triangularibus, ultimo anguste ovato, acuminato ; prothorace 
* There is some confusion in the synonymy here. Taking Lacordaire’s 
note (Gen. vi. p. 555) as correct, the following would be the chronology :— 
Rhynchites celestinus, Gyll., 1833. 
grandis, Imhoff, 1838. 
—— philippensis, Chey., 1841. 
Yet Lacordaire, adopting the two latter names, gives the first as a syn- 
onym for both. j

and Sumatra.
