The remainder oi: the Pyralidce, the Crambidce, Phycitida, and 

 Tineidce I can do nothing with, excepting that there is one rather 

 good example of Di/sphi/Ua viridella, Eagonot, from the Sabaki 

 Valley. 



The Geometridcp are also mostly in bad condition, but the 

 follo\ving are identifiable : —

Nearest to 0. megalaria : wings silvery greyish white, with faint 

 brassy reflections ; costa of primaries slightly browner ; an oblique 

 black bar on the discocellulars ; a slightly arched grey stripe 

 crossing the disc parallel to outer margin and followed by two 

 very badly-defined submarginal stripes, the inner one often partly 

 obliterated; two more slender stripes traverse the fringe of all 

 the wings. Head, prothorax, and patagia brownish grey ; remainder 

 of body whitish ; antennae white, with blackish pectinations in 

 the male. Wings below greyer, all the veins pale bufi: ; costa of 

 primaries with a golden reflection, irrorated with grey, traces of 

 the commencement of the first two transverse stripes as far as 

 upper radial vein ; discocellular bar replaced by a cuneiform 

 oblique whitish-edged black spot: secondaries white irrorated with 

 grey ; the costa tinted with pale buff ; a black spot on upper 

 discocellular and a series of four black dots on the median and 

 radial veins ; a submarginal squamose brownish-grey line ; margin

Primaries above silver-grey, divided into three nearly equal 

 parts by two white irregular stripes, which indicate the central 

 band, the inner stripe } -shaped, the outer wider, better defined, 

 undulated, almost in the form of the Greek letter ^ (but with the 

 tail continued almost to the length of the character) on the left 

 hand side ; on the right hand it consequently more nearly resembles 

 a figure 3, also with the lower extremity continued : secondaries 

 pui'e white, crossed before the middle by an equally bisinuate grey 

 band, the centre between the two sinuations forming an acute 

 angle directed outwards ; a dotted grey line, duplex at abdominal 

 margin, followed by an external rather broad grey border ; a sub-
