(Group SERICORIS, Tr.) 

 Penthina major y sp. n. 



Antennce greyish fuscous, spotted above with white. Palpi 

 pale fawn, the apical joint fuscous. Head and Thorax fawn-grey. 

 Forewings fawn-brown, speckled with pale ochreous, with two 

 pale ochreous transverse fasciae margined on both sides by shining 

 silvery bands ; the apex is mottled with pale ochreous preceded by 

 an angulated silvery band ; the first fascia is at one-third from the 

 base, its inner margin slightly concave, its outer margin slightly 

 bulging outwards on the cell ; the second fascia leaving the costal 

 margin beyond the middle runs obliquely to the anal angle, the 

 silvery bands which bound it being deflected inwards to the dorsal 

 margin from about the lower angle of the cell, a few fawn-brown 

 spots along the costal margin encroach upon the upper edge of the 

 pale fasciae ; cilia white, with some grey shading at their base, 

 especially around the apex. Exp. al., 23 mm. Hindwings fawn- 

 grey, with whitish cilia. Abdomen greyish fuscous, anal tuft 

 ochreous. Legs white.

Allied to 8. constellatana, Z., but the silvery markings 

 confined to the margins of the fasciae, not scattered 

 between them ; it is also a larger and more distinctly 

 marked species. 



P^DISCA, Tr. 



-"Psedisca Tiyponomeutana, sp. n. (PL XII., fig. 12.) 

 Antennce, (, biciliate (^), rather stout; white. Palpi 

 moderately clothed, projecting slightly beyond the head ; apical 

 joint short, drooping ; white. Head thickly clothed above and in 

 front ; creamy white. Thorax shining white, with two lateral 

 black spots posteriorly ; tegulae with a few black scales across their 

 middle. Forewings with the costal margin straight, apical margin 

 slightly oblique, anal angle rounded ; shining white sprinkled with 

 distinct black angular spots to the number of about fifty : of these 

 one only, at about one-sixth of the wing-length, is actually 

 contiguous to the costal margin, others beyond, approach it very 

 closely, but there is no apparent regularity in the arrangement of 

 the spots, which are for the most part transversely elongate, a 

 somewhat regular series of about ten extending from the base 

 immediately below the fold ; a second series of about six below it,
