THE CANADIAN ENTOMOLOGIST. 29 



Fourteen specimens, embracing bvOth sexes, are at hand, and others 

 have been reared. Examples bearing a co-type label will be placed in the 

 U. S. National and British Museums, where the species is already 

 represented by specimens from Rye, N. Y. It must have a wide distribu- 

 tion over the Middle Atlantic States, though Webster, N. H., is the only 

 other locality positively recalled. Sciata resembles both cerussata and 

 frigida, but its smaller size, darker tone and absence of white basal spots 

 superficially separate it, while its larva is entirely different. For descrip- 

 tion of the latter, with notes of early history, consult this magazine (Can. 

 Ent., Vol. XXXIII, p. 64). Correspondents will now bear in mind the 

 change in the limpida label. 



There seems reason for the introduction of two other species at this 

 time, in view of forthcoming literature, so that our list may be as fully up 

 to date as possible. One of these is a Pacific Coast form, the other an 

 eastern one, which probably has a boreal tendency. While it might have 

 been better to await a larval acquaintance, it is feared this desideratum 

 may be too remote to be waited for. 



Papaipema imperspicua^ n. sp. — Form congeneric, front smooth. 

 Ground colour yellowish-brown. Antennae minutely ciliate, no white 

 scales at base. Head and thorax purple-brown, the erect tuft spreading at 

 the top, posterior tuft and the abdominal ones also normal. Basal spots 

 indistinct, of the ground colour. T. a. line geminate, of the usual sinuous 

 course, but its lower section bends outwardly and encloses more area than 

 is usual ; this area is an even, dull purple. The t. p. line is distinctly 

 geminate and even in its course, the inner line a tine brown lunulate 

 marking. It has an angled bend as it passes the reniform, rather than the 

 broad sweep which is common to so many. The median field is yellowish- 

 brown, the lower part yellower and brighter. The shade line is distinct 

 and of a deep brown. The central marking of the reniform is all that 

 appears, defined in a lighter hue of the ground colour. Orbicular and 

 claviform wanting. The s. t. line is a fine lunulate yellow marking ; at 

 the costal tip there is outwardly a yellow dash. The terminal space is the 

 even shade of purple which holds inside the t. a. line, the subterminal space 

 is yellowish-brown again. Secondaries even smoky-brown. The male 

 structures agree with the pattern of iiitela, the outwardly dentate harpes 

 with a prolonged lower lobe, and the heavy spinulated tip, follow the 

 common design. Expanse, 1.50 in.; 37 mm.
