594 Mr. Pascoe's flescn'pi/'ons of Carculionidae, 



Differs from S. luguhris in its broader outline, finer granu- 

 lations, and the protliorax granulate, not punctate. 



Siteutes ccsruleatns. 



S. late subovatus; prothorace la^vi, nitide rufo-testaceo ; elytris 

 subtiliter granulatis, cffiruleo-squamulosis. Long, o-fi lin. 

 Hab. Yule Island. 



Broadly ovate, head, rostrum, and antennae as in the last, the 

 latter sprinkled with small blue scales ; prothorax very smooth 

 and glossy, chesnut-red; elytra short, rather depressed, studded 

 with small granules, the intervals covered with small blue scales; 

 body beneath black; legs dark chesnut, with scattered bristle- 

 shaped scales. 



Only traces of the blue scales sometimes remain; the highly 

 polished prothorax is distinctive. Siteutes was foimded by 

 Schonherr on an African form unknown to Lacordaire, who took 

 his description of the genus from >S'. luguhris — a Philippine 

 insect ; it is possible that the two are not congeneric. My S. 

 glabratus, from its concave and somewhat bilobed mesosternum, 

 should probably represent a genus of its own. 



DIETHICUS. 



HdStntm capite paulo angustius, hand compressum, supra 

 utrinque elevatum, a capite separatum ; serohes superiores, pro- 

 fundje, foveiform^s. Antenn<£ elongata? ; scajnis curvatus, apice 

 hand incrassata, elytrorum basi superans ; funicubis tenuior, 

 articulo secundo primo vel tertio duplo longiore, ca;teris sub- 

 cylindricis; clava parvula. Frot/iorax brevis, baud lobatus. 

 ScuteUuiH nullum. Elytra ampla, exhumerata. Pedes brevius - 

 ci;li; ungues basi comiati. Ahilomen segmento secundo duobus 

 sequentibus longiori. 



Allied to ElUmenistes, Schcin., but differs in form of the 

 rostrum, which is broader, and not compressed, the longer 

 antenna;; and the scape not enlarged, or only at the extreme 

 point, at the apex. 



Diethicns tumens.
