PHOXOPTEEYX.— DICHEOEAMPHA. 75 



shining bluish streaks^ two o£ which before the middle of the costa blend into a narrow, wavy, 

 white, oblique double fascia ; other two beyond the middle are irregularly continued towards 

 the anal angle ; some abbreviated silvery-white costal streaks before the apex and two white 

 spots in the fuscous cilia below the apex ; towards the anal angle the cilia are whitish, 

 touched with fuscous. Hind wings rather paler fuscous, with a brownish tinge. 1 $ . 

 Expanse of wings 13 millims.

RHYACIONIA, H.-S. 

 Ehyacionia juncticiliana. (Plate LXXVII. fig. 9.) 



Palpi depressed, acute, thickly clothed, the apical joint not exposed, together with the 

 head tawny red : antennae pubescent in the male : thorax and fore wmgs rosy whitish ; the 

 latter (with the costa gently arched, the apical margin oblique) minutely streaked with wavy 

 lines of tawny red, and shaded off gradually from the base — ^first, towards a darker tawny-red 

 oblique central fascia outwardly margined with white, and, secondly, beyond it towards the 

 tawny-red apical margin : an obsolete basal patch is faintly indicated towards the dorsal 

 margin : the costal portion of the wing, just beyond the central fascia, has a strong rosy tinge : 

 a line of fuscous scales runs along the apical margin at the base of the cilia, which are also 

 rosy and are not separated by any pale line from the darker shade of the apical portion of 

 the wing, as in the allied species R. hastiana, Hiibn., which has also the costa more abruptly 

 arched towards the base. Hind wings minutely speckled greyish fuscous. 7 ^ . Expanse of 

 wings 20 millims.

DICHEOEAMPHA, Guen. 



Dichrorampha radicicolana. (Plate LXXVII. fig. 10.) 



Palpi tawny, projecting nearly twice the length of the head beyond it, profusely clothed, 

 the apical joint concealed: head tufted above, tawny; antennae the same. Fore wings pale

 a basal patch, acutely angulated externally beyond the middle of the cell, is shaded within its 

 outer margin with tawny brown ; a triangular patch of the same colour before the anal angle, 

 the intermediate abbreviated pale fascia interrupted by waved tawny lines : a tawny brown 

 shade on the apical margin, extended inwards towards the middle of the wing, and a few short 

 paler brown streaks from the costa : the cilia rather shining yellowish white, divided in the 

 middle by a tawny line parallel with the apical margin j a fuscous spot on the cilia at the 

 apex. Hind wings brownish fuscous ; the cilia yellowish white, divided by a tawny line. 1 ? . 

 Expanse of wings 17 millims.
