STROBISIA. 81 
is a deep blackish patch extending to the costa and produced outward nearly to the apex, this contains a 
pair of rather converging silvery white costal streaks and a small spot of steel-grey towards its lower 
extremity, the space beyond it to the apex and termen, including the cilia, being rich shining purple. 
Exp.al.12mm. Hindwings dark coppery brown; cilia purplish grey. Abdomen brownish fuscous. 
Legs: hind tibiae shining, brownish grey, with a white annulus at their end; the tarsi darker, with the 
terminal joint white.

CoLoMBIA: MAGDALENA: Santa Marta, 1865 (P. Bouchard; Stn. Coll.). Three 
specimens. 
I am indebted to Commander J. J. Walker for this, as well as for many other very 
interesting forms: it is of much the same appearance as several species collected on 
the Amazons by Bates, and described from specimens in the British Museum by 
Francis Walker, but does not agree with any in the distribution of its beautifully 
distinct markings. 
3. Strobisia scintillula, sp.n. (Tab. IIT. fig. 1.) 
Antennae brownish above, ochreous beneath; slightly serrate towards the apex. Palpi white on their inner 
sides, tinged with grey externally, especially at the end of the median joint; apical joint inclining to 
ochreous. Head and Thorav brownish fuscous. Forewings dark brown, with a bright steel-blue spot 
at the base of the costa, a slender, outwardly curved steel-blue line at one-fifth from the base, two white 
costal streaklets, one before and one beyond the middle, beneath which are three steel-blue spots, two on 
the cell and one beneath the fold, and a wide steel-blue band before the termen projecting inwards above 
the middle; along the margin beyond this an ochreous band runs to the apex, separated from the 
whitish apical cilia by a dark line; cilia on the lower half of the termen dark greyish fuscous; the basal 
patch within the first blue line, and the central fascia indicated by the white costal streaks, are very 
slightly paler than the ground-colour. EZwp. al. 10 mm. MHindwings brown; cilia slightly paler. 
Al,domen fuscous, banded transversely with steel-grey; white beneath. Legs fuscous, with white patches 
at the extremities of the tibiae, and smail white spots on the tarsal joints; spurs white.

4, Strobisia argentifrons, sp.n. (Tab. III. fig. 2.) 
Antennae dark brown, with slender pale annulations. Palpi very slender, moderately recurved, terminal 
joint as long as median; whitish. Head and Thorax dark bronzy brown; face silvery. Forewings dark 
bronzy brown, with a slight leaden grey sheen at the base, extending to the dorsum below the fold, 
followed at one-third by an oblique leaden grey costal spot, beyond which are two silvery costal streaks, 
one at three-fifths, and one before the apex, both tending obliquely outward; the dark brown cilia have 
a pale line at their base, a rather wider line beyond their middle reaching around their apex. Exp. al. 
8mm, Hindwings 1, sinuate below the rounded apex; pale bronzy brown, with a reduplicated pale 
line in the cilia, at the apex only. Abdomen dark brown, with a cupreous spot at the base above; 
silvery white on the underside. Legs dark brown ; hind tibiae with broad white bands, corresponding 
to each pair of spurs which are also white ; tarsi with three white spots at the joints, and one at the end 
of the last joint.
