102 OTIORIIYXCHID^. 



[Horn. 



Second segment longer than tlie two following, first suture 

 strongly arcuate. Second joint of funicle longer than 



the first gen. nov. 



The type of the second genus is Oeo7ie?nus alternann Boh. (Cuha). The 

 articular surfaces of the hind tibite are not scaly in this species as stated by 

 Lacordaire, Genera, vi, p. 131. Q. aureosquamosios Duval, (Cuba) does 

 not belong to the present tribe, but should form a new genus of Cyphini, 

 as defined in the present memoir. 



OMILETJS n. g. 

 Rostrum longer than the head and very slightly narrower, cylindrical 

 at base, slightly flattened above, feebly dilated and emarginate at tip ; 

 genae not emarginate. Scrobes deep, well defined, slightly arcuate, passing 

 obliquely beneath and slightly in front of the eyes. Eyes oval, slightly 

 longitudinal. Antennae moderate ; scape attaining the posterior margin of 

 the eyes, feebly thickened ; funicle 7-joiated, first joint moderate, second 

 scarcely longer than the third, 3-7 short, sub-equal ; club oval. Thorax 

 truncate at apex and base. Scutellum small, oval. Elytra oval, not wider 

 at base than the thorax, humeri broadly rounded. Metasternum moderate. 

 Intercoxal process bi"oad, rounded in front, second segment equal to the 

 two following together, first suture very nearly straight. Anterior and 

 middle tibiie mucronate. Articular surfaces of hind tibiae feebly cavernous, 

 glabrous. 



O. epicaeroid.es, n. sp. 



Form elongate, oval, surface densely covered with cinereous scales, 

 variegated with brown. Head and rostrum slightly longer than the thorax, 

 densely punctured and covered with cinereous scales, at tip nearly naked. 

 Thorax as broad as long, apex slightly narrower than the base, sides 

 strongly arcuate, median line moderately impressed, surface sparsel}' tuber- 

 culate, densely covered with cinereous scales, a broad median and narrow 

 lateral stripe fuscous. Elytra regularly oval, striate, striae with moderately 

 coarse punctures, intervals feebly convex, and each with two rows of 

 scale-like hairs, surface densely covered with cinereous scales, disc with 

 large fuscous spot nearlj"- divided by a transverse cinereous fascia inter- 

 rupted at middle. Body beneath densely covered with cinereous scales. 

 Legs densely scaly, femora darker at base. Length .30-.33 inch; 7.5-8 mm. 



The facies of this species is almost exactly that of certain elongate forms 

 of EpiccBi'us imhricatus, and it would have been placed in the same tribe 

 if the structure of the sternal side pieces were similar. 



This species occurs in Texas. 



Group III. Evotl. 



Rostrum elongate, strongly dilated and auriculate at tip. Scrobes visible 

 from above. Scutellum distinct. Elytra wider at base than the thorax, 

 humeri moderately prominent ; marginal stria entire. Articular surfaces 

 of hind tibiae feebly cavernous. Claws free. 



One genus only is known to me which can be placed here.
