Oribates, nov. gen. 



A genus of small moths, having at first sight the appear- 

 ance of Pyralidse. The palpi are rather long, densely clothed with 

 hairs ; thorax moderately stout, vestiture hairy, passing into 

 flattened scales, at the junction of the abdomen, which is some- 

 what extended beyond the posterior wings ; legs clothed with 

 closely appressed hairs ; fore tibiae unarmed in both sexes ; the 

 two posterior pair, each with a long spine ; Antennae simple- 

 wings moderately broad, verj^ much rounded on the apices. 



Oribates muirii, n. sp. 



Primaries dull orange, flecked with blackish scales, and the 

 base shading into deep brown ; in the central space there is also 

 a blackish cloud, and the posterior margin is also blackish, as are 

 the fringes. Secondaries, a rather lighter shade of orange, with 

 a narrow regular marginal border, and the fringe black. Under- 

 side, entirely dull orange, with a narrow marginal border, and 

 small discal spot on the primaries, black ; palpi whitish, as is 

 also the base of the tibiae; thorax bluish, with some yellowish 

 and brown hairs ; abdomen, black at the base, the posterior half 

 dull orange, concolorous with the posterior wings. Expanse of 

 wings S 0.40, ? 0.50, inch, 2 c? 3 ? . Tuolumne Co., Cal. Jno. 

 Muir, to whom I have great pleasure in dedicating this interest- 

 ing species.

Oribates limbatus, n. sp.

 brownish patches on the costa : posterior portion, rich purplish 

 brown, mottled with a paler shade; a dark brown, triangular 

 patch on the costa near the apex ; fringe two shades of brown ; 

 Secondaries, bright orange, with marginal line of black ; fringes, 

 brownish ; thorax and abdomen above concolorous with the base 

 of the forewings ; beneath whitish, as are also the tarsi ; the un- 

 der side of the wings is orange, as in O. Muirii, with some small 

 brownish patches on the costal edge of primaries, and the apex 

 also broadly brownish. Size of O. Muirii. 



4^,5? Mazatlan, Mexico. 



Type. Coll. Hy. Edwards. 



This insect when disturbed, alights among loose stones, 

 something after the habit of Syneda, and it is then extremely 

 difficult to discover. The specimens in my possession were taken 

 on a rocky hill near the city of Mazatlan. It may yet be found 

 within our borders.
