Bohemanni, Schh. There is nothing in the description of C. 
-angularis on which any opinion could be formed as to the correct- 
ness of the above synonymy. 
HYBORRHYNCHUS. 
H. aurigena, sp. nov. Piceus, squamis albidis fuscisque inter- 
mixtis confertim vestitus; rostro lato brevi, utrinque 
obtuse carinato- marginato, margine supra - oculum 
abrupte desinente tuberculum conicum simulanti; capite 
postice convexo, a clypeo sulco profundo distincto, pone 
sulcum longitudinaliter rugato et tuberculis parvis instructis, 
in vertice anguste impresso et bituberculato; prothorace trans- 
verso, postice angustato, canaliculato, supra sat plano confuse 
tuberculato, ad latera utrinque ante medium acute bituber- 
culato ; elytris seriatim tuberculis parvis instructis (tuber- 
culis inter se sat equalibus, crebre dispositis, singulis setas 
singulas ferentibus), biseriatim in interstitio 3° leviter 
4-gibbosis, ad apicem inermibus. Long. (rostro. inel.), 5 1. ; 
lat., 14 1. 
The absence of a mucro at the apex of the elytra distinguishes 
this species from all its previously described congeners except 
rugosus, Macl., crassiusculus, Macl., and Mastersi, Macl. From 
rugosus and Masters? it differs, inter alia, by its elytra having no 
tubercles notably larger than the rest about the hind declivity, 
and from crassiusculus by the very different sculpture of its head 
and prothorax.

CENTYRES. 
C’. delens, sp. nov. Piceus, setulis brevibus albidis minus crebre, 
et. squamis ochraceis fuscisque dense vestitus, his in pro- 
thorace medio vittatim et in elytris disperse maculatim con- 
densatis ; antennis fuscis, scapo modice elongato, articulis 
basalibus 2 sat elongatis inter se sat eequalibus; rostro sub- 
obsolete tricarinato; prothorace leviter transverso, antice 
leviter angustato, punctulato, obsolete vermiculato-ruguloso, 
lateribus minus fortiter rotundatis; elytris ampliatis, sat 
convexis, punctulato-striatis, interstitiis leviter convexis ; 
tibiis anticis intus minus perspicue denticulatis,—posticis ad 
apicem cavernosis ; abdominis segmento 2° quam 3" parum 
longiori. Long. (rostr. incl.), 4 1.; lat., 121. 
Differs from the previously described species by the median 
fuscous vitta of its prothorax and the small fuscous spots on its 
elytra, and by the less distinct denticulations of its front tibie. 
Compared with C. twrgidus, Pasc., it is much smaller, &c.; with 
ovis, Pasc., it is of considerably more convex build; while i
