AMERICAN COLEOPTERA. 417 



As here defined the characters of tlie genus, as distinctive from 

 the other genera of the subtribe Cceliodes, are negative rather than 

 otherwise. The type of Oeliodes Sch. is the European C. quercus ; 

 this species, however, has the femora mutic and the pectoral canal 

 prolonged to nearly the end of the metasternuin and was subsequently 

 made the type of Meyacetes Thomp.* Of eleven European species 

 of Qeliodes in my collection, all, except (jiiftu/d Fab. and ejnlobii 

 Payk. (Auleutes) have the second ventral segment longer than the 

 two following together, the latter very short, the third widely attain- 

 ing the lateral margin. 



The two species occui-riiig in our fauna are densely squamous 

 insects, and are distinguished as follows: 



Larfter, oval, lateral tulni'clcs of ]injthorax obsolete, lat(>ral spot aiul apex of 



elytra pale apiealis. 



Smaller, elliptic, lateral tubercles disiiiicr, no elytral spots vitiOSillS. 



C. ai>iCHli«« n. sp. — Oval, dark brown, aiitennie and legs a trifle paler, densely 

 clotlied above and beneatli with oval scales, brownish above with lateral and 

 apical spot of the elytra of pale scales, scales of the underside dirty ;;rayish white. 

 Beak rather slender, curved, longer than the prothorax, subcarinate from the 

 middle to near the apex, densely punctured and thinly stjuamous near tlie base, 

 scroljes directed against and expanded befoi-e the eyes; antennse inserted almost 

 two-fifths from the apex (^ and 9 )< slender; first and second joints of funicle 

 elongate, following joints sliorter, outer a little widened, club elongate or acumi- 

 nate. Head densely punctured, squamous, front flattened ; prothorax scarcely 

 wider than long, moderately narrowed anteriorly, rounded on the sides, apex 

 dee])ly constricted, deeply impressed behind the apical margin, ocular lobes nearly 

 obsolete, basal inargin straight each side, dorsal channel more deeply imi)ressed 

 before and behind or subinterrupted at the middle, lateral tubercles obsolete, in- 

 dicated by a short ridge-like elevation, surfixce densely and rather evenly punc- 

 tured, punctures small, sides clothed with pale scales; scutel glabrous, scarcely 

 visible. Elytra scarcely one-fourth wider at the base than the prothorax, a little 

 longer than wide, broadly and regularly rounded on the sides, nioderatel.v con- 

 vex, strife fine, deep, punctures very small, each bearing a pale scale, interspaces 

 wide, flat, rugulose, a sutural line from the fii^st third to near the apex, of darker 

 scales with some lustre, an oblique spot on the 6-9 interspaces before the middle 

 and apical margin, of pale yellowish white scrobes, the apical pale space encloses 

 a dark spot; metasternum deeply emarginate, excavate; underside of body 

 closely and suiterficially punctured; femora dentate, obscurely annulate with 

 pale scales near the apex, tibiie somewhat stout and widened towards the apex, 

 obscurely annulate near the i)ase and apex, tiirsi elongate, third joint not broadly 

 biloiied, fourth shorter than the two preceding joint.s, claws armed with a slender 

 tooth about one-half the length of the claw, the first and second joints with sev- 

 eral l)ristle-like hairs arising near the a])ical margin ; pygidium densely and finely 

 punctured, pubescent. Length 2.7.5-3.25 mm. ; 0.11-0.13 inch.
