8 Mr. R. Trimen on 
neuration (especially in having one more subcostal nervule 
in the forewings), outline of wings, and Zeritis-like under- 
side; but agreement between the two genera is found in 
the antennez, the slender structure, and the colouring of 
the upperside. The relation to Zeritis is shown towards 
the rather aberrant section of that genus which wants the 
usual fifth branch of the subcostal nervure in the fore- 
wings, and includes Z. chrysantas, Trim., and Z. leroma 
(Waller.) ; and it is the last-named species to the colour- 
ing of whose underside that of D. mazoensis exhibits so 
much resemblance. 
Desmolycxna mazoensis, sp. n. (Pl. I, fig. 4). 
6 Exp.al. Udlin.—lin. Greyish-brown, strongly shot throughout 
with bright violaceous; hindmargins with a linear fuscous edging ; 
cilia white ; on submedian nervure of hindwing a linear black tail, 
reddish at base and conspicuously white at tip. UNnbErstpE.—Pale 
brownish-grey, with numerous silvery and black spots ; a hindmarginal 
linear black edging emitting a short acute projection on each ner- 
vule ; in each wing the following silvery spots, vid.: a linear 
transverse terminal disco-cellular mark, finely dark-edged on both 
sides ; some sub-basal and cellular spots; a highly irregular discal 
series of eight ; and a regular submarginal series : all these silvery 
spots slender and many sublinear, most of them edged in parts with 
some black scales, and each (except the terminal disco-cellular ones, 
two in discoidal cell of forewing, and one close to anal angle of fore- 
wing, and one close to anal angle of hindwing) succeeded by a 
completely separate black spot of corresponding size. Forewing: A 
short silvery streak along lower edge of costal nervure near base, 
some silvery scales near costal margin, and three spots in discoidal 
cell towards the extremity ; the exceedingly irregular discal series of 
spots is preceded by a subcostal row of three, placed longitudinally 
between 1st subcostal and upper radial nervules, the outermost of 
these making the uppermost of the discal series of six; the black 
spots accompanying these discal ones increasing in size downward to 
below Ist median nervule ; below median nervure and its Ist nervule 
a sub-basal black spot followed by a premedian one. Hindwing : 
some silvery basal scales, succeeded by a partly indistinct series of 
five very small silvery and blackish spots running straight from costa 
to inner-margin—the 3rd spot being in discoidal cell ; a sub-basal 
series of three elongate silvery marks, with accompanying separate 
black marks, between costal and submedian nervures—the middle
