A beautiful moth readily recognized by the nine black spots on the 

 lower part of the outer edge of the fore wings ending in bright, metallic 

 points. 



Caladysta metalliferalis, n. sp. — 1 (? 3 $ . "Wings rather broad ; hind wings 

 deeply notched. Pale brown with an ochreons tinge ; thorax ochreous. 

 Fore wings ochreous brown, an obliquely straight white basal line ; a par- 

 allel similar line beyond, bent on the costa, enclosing a broad pale brown- 

 ish band; a broad white band, diffuse externally, crosses the wing, and is 

 limited extei'nally by a filiform brown minutely zigzag line, which is much 

 curved above the fourth median venule, and just below sends an acute 

 angle inwards. (This line is more distinct in rubbed specimens). A mar- 

 ginal white line very diffuse on the inner side ; beyond it towards the costal, 

 a narrow ochreous brown line. Still beyond are two or three very fine dis- 

 located hair lines at the base of fringe, which is pale brown, consisting 

 of brownish and whitish scales. Hind wings whitish at base, a few dark 

 long spatulate scales along the hinder portion of the wing. A dark spot 

 within the middle of the inner margin of the wing. An outer cui'ved 

 waved brown line, edge of wing brown. The white band below the notch 

 enclosing five conspicuous black dots, with five black square spots beyond 

 alternating with bright shining metallic points. Abdomen pale brown, a 

 few ochreous scales at base ; segments whitish on hinder edge. Legs 

 whitish silvery. Wings beneath dull ash brown, a whitish discal streak, 

 the outer line common to both wings, dusky and obscure ; the marginal 

 white line distinct towards the costa, but the other lines not reproduced. 

 Blacli and metallic points as above.

This species has the conspicuous, black and steel blue metallic spots 

 on the hind wings, as in our eastern, and in the Brazilian species, de- 

 scribed by Guenee. It does not follow the analogy of the European 

 C. lemnalis, in which, as Guenee observes, the black and metallic points 

 are represented by simple white points. 



Pyralis 'farinalis Linn. Two specimens from California, collected by 

 Mr. Edwards, do not differ from New England examples. 



Fam. PteroplioridLcie. 



Pierophorus pergracilidactylus. n. sp. — 1 $ . A very slender species, 

 with a long body, very long legs, and the wings unusually long and nar- 

 row. Body and wings ash brown. Head whitish on vertex, reddish brown 

 in front; palpi reddish brown with some white scales. Antennae whitish 

 ringed with brown. Thorax brownish above, becoming whitish on the 

 sides and extending along the abdomen ; a small dark irregular dot on the 

 front end of each abdominal ring; brown on the sides with scattered dark 

 scales ; beneath whitish with numerous dark scales, with a pair of large 

 dark spots usually meeting beneath. Fore wings very narrow, split Avidely 

 apart the usual depth ; the costal branch narrow and curved ; the hinder
