336 AMERICAN LEPIDOPTERA. 



iVIesoleuca (Philereme) californiata Pack. (Proc. Bost. Soc. Nat. Hist., 

 xiii, 399, 1871). 



This species was described with others by Dr. Packard in the 

 above publication in advance of his Monograph, and in a later vol- 

 ume of the same journal he gave a recognizable figure of it (xvi, 

 pi. 1, fig. 12, 1874). In a note preceding the descriptions he stated 

 merely that the species were collected in California, but the number 

 of specimens of californiata was not given. In the Monograph the 

 description was repeated, and from the localities and dates given 

 there were at least four specimens. 



In the Hulst collection there are four specimens as californiata, 

 but which represent two species. Of one of these there are three 

 examples, one of which is marked as having been compared with 

 Packard's type. This, however, does not agree with either the 

 description or figure of californiata. 



In the Packard collection there are three specimens with printed 

 type labels, and two bear written nanu labels in addition, one Phile- 

 reme californiata, the other Scotosia californiata. The latter of these 

 two is the species that Packard described and figured, and is the 

 same as the single specimen Hulst had under this name; the former 

 is like Hulst's "typical californiata,'" of which he had three speci- 

 mens. This has not been described, so is characterized below as 

 Hydriomena indefinata, new species. 



Californiata must be transferred to Hydriomena, though the 

 change renders it necessary to rename it on account of its preoccu- 

 pation in that genus. I should prefer to refer it to Mesoleuca where 

 the name would not have to give way, but the distinctly flattened 

 antennse prevents its entrance into that genus. The name packarxl- 

 ata is therefore proposed for californiata. 



Hydriomena indefinata u. sp. 



Expanse 39-44 mm. Palpi brown, white at tip, projecting in front of head 

 almost as far as the distance between the eyes. Front and vertex brown, inter- 

 mixed with dirty white scales. AutenniB flattened, light brown at the sides, 

 dark brown above. Thorax even brown. Abdomen brown, the apex of segments 

 pale yellowish, which is preceded by two dark brown dorsal spots. Primaries 

 broad, with costal edge produced outwardly on basal half; outer margin slightly 

 waved. Color, smooth brown, slightly darker in small basal and broad median 

 areas, especially on anterior portion along extradiscal line of latter. Costa 

 marked on basal half by five small yellowish spots. Cross lines a slightly deeper 

 shade of brown than the ground color and very indefinite. Basal line situated 

 not far out on the wing, strongly outcurved to radius, then turned inward almost
