Xylina Ochs. 



The following descriptions in this genus are presented in advance 

 of a systematic treatment of the genus at large and to permit the dis- 

 tribution of material before the publication of the revision, which 

 may be somewhat delayed. 



Xylina torrida, sp. nov. 



Ground color bluish gray. Antennce white basally, else brown. Head with a 

 black line across the middle of the front, the vertex usually a little smoky. Collar, 

 as a rule, paler than ground color, sometimes whitish, usually with a reddish flush to- 

 ward a sub-apical black line, which in some examples is almost obsolete. Thorax 

 more or less white powdered, not definitely marked, patagise black edged at the base 

 of the wings. Abdomen with a reddish flush in well preserved specimens. Pri- 

 maries more or less powdered with smoky or blackish scales, varying the tint and 

 often clouding the median space. Basal line geminate, blackish, marked through the 

 costal cell only. A black longitudinal line extends from the base through the s. ra. 

 interspace half way to the t. a. line and is then obliquely extended by a black or 

 blackish shade to the costa within the origin of the t. a. line. The space included 

 in this boundary at the base of the wing is whitish or much paler than the rest of the 

 wing, further emphasized by a rusty shading just above the black streak. T. a. line 

 geminate, black, the outer portion most sharply defined, outcurved in the interspaces 

 and quite sharply toothed inwardly on the veins, as a whole a little outwardly oblique. 

 T. p. line lunulate, geminate, outer line smoky, indefinite and quite even, lines black, 

 often disconnected and tending to obsolescence : as a whole the line is outwardly ex- 

 serted over the reniform and almost upright below that point. S. t. line marked by a 

 series of triangular black, preceding spots, except at the costa where a smoky shade 

 precedes it. This series of spots is in a way the most prominent and certainly the 

 most constant feature of the wing. A series of terminal spots which are not at the 

 extreme edge of the wing and which are elongate though not connected into a line. 

 A more or less diffuse median shade, almost or quite filling the space between the or- 

 dinary spots, parallel with and close to t. p. line below the reniform. Claviform black 

 ringed and sometimes almost black filled, small, pointed, not reaching the middle of 

 the median space. Orbicular upright, oval, of good size, as pale as any other part of 

 the wing, black ringed except superiorly ; below the median vein there is attached to 

 it a smaller, less prominent, sub-orbicular, which is usually smoky centered and may 

 become entirely obscured. Reniform large, upright, oval, only a little kidney-shaped, 

 black ringed, centered with smoky in which is a reddish shading. The veins are 

 more or less smoky. Secondaries smoky with a reddish tinge, sometimes quite pale. 

 Beneath with a reddish flush, powdery, both wings with an outer smoky line and 

 round discal spot. Expanse, 40-46 mm. = 1. 60-1. 80 inches.
