302 AMERICAN MICRO-I.EPIDOPTERA. 



LiithocoUetis propinqiiiiiella sp. nov. 

 Plate XXII, Fig. 9. 



Antennffi dark gray. Face and palpi silvery. Tuft dark brown mixed with 

 whitish scales. 



Thorax brownish golden, with a white line across the anterior margin, passing 

 over the patagia and continuous with the basal streak on the forewings. Fore- 

 wings brownish golden in the male and darkened with brownish scales along 

 the middle and in the dorsal half; more golden in the female. The rather broad 

 basal streak, pointed at the apex, ends at about two-fifths of the wing length 

 and is black margined above and around its apex. Dorsal margin narrowly 

 white toward the base. Four costal and three dorsal white streaks. First costal 

 just before the middle, very oblique, and dark margined internally and around 

 its tip behind. The other three costal streaks nearly perpendicular and dark 

 margined internally only. First dorsal streak commencing much nearer the 

 base than the first costal, long and oblique, its a]iex reaching beyond that of the 

 first costal, sometimes almost to the space between the second costal and dorsal 

 streaks. It is dark margined on both sides. In the male its internal dark mar- 

 gin is indented on the fold, in the female it is almost regularly inwardly convex. 

 An accumulation of blackish brown scales, densest in the male, between the sec- 

 ond pair of streaks extends l)ackward along the middle of the wing to the aj)ex. 

 Marginal line in the cilia blackish, with a bluish metallic luster. Cilia grayish 

 ocherous, less gray in the female. Expanse 8-9 mm. 



Hindwings and cilia grayish, with a fulvous tinge. Abdomen 

 dark gray above, silvery beneath. Anal tuft gi-ayish in the male, 

 ocherous in the female. Legs grayish ocherous, tarsi gray above. 



A common underside miner on wild cherry, Prunus serotina Ehrh. 



A much more common species than L. craiccgella Clemens, and 

 more closely related to the European blancardella,i'rom which, how- 

 ever, it is distinct. It differs from cratcegella in the much larger 

 size and the more oblique first dorsal streak, which is also relatively 

 much nearer the base of the wing than in crutcvgella.

 "Antenna; whitish, faintly spotted above. Palpi shining white. Face shining 

 white, frontal tuft while, with a few saffron scales at tl.c sides. Thorax bright 

 reddish saffron, with a thin whitish line running around its anterior margin and 

 communicating with the basal streak on the forewing. 



"Forewings bright brownish saflFron, with a long slender medio-hasal white 

 streak without dark margins, four costal and three dorsal streaks of the same 

 color, sometiines with a slight metallic sheen ; the first costal streak is a little 

 before the middle of the wing, oblique and pointed, with a scarcely jierceptible 

 dark dusting along its inner margin ; the first dorsal streak commences a little 

 nearer to the base; it is dark margined internallj', and is somewhat wider than
