hamatus and sylphis) there is a black band (or three spots) below the antennae; 
In manicatus no band; in tigris the basal spot of hind wing is large, in manicatus 
smaller or nearly absent; the last joint of palpus seems to be longer in tigris than 
In manicatus. 
But the difference, which if constant is conclusive, is in the male genitalia. 
I have before me three male manicatus and five male tigris; the long superior 
appendages appear to be the same in both, both 
a, with the same recurved process toward base; the 
a ventral plate also appears to be the |same, possibly 
= a little longer in tegris; but between these two is a 
short bent process with a bristly head: in all the 
tigris the tip of this process is entire and evenly 
truncate, in all of the manicatus the tip is bifid, the 
basal lobe bristly, the posterior lobe smooth; the 
figures (Fig. 28) show the difference. It is barely 
possible that this smooth lobe seen in manicatus is 
an extensile process extruded, but inasmuch as the 
two series are constant I am inclined to believe it

Black, head, thorax, coxae, femora and extreme base of 
abdomen densely clothed with long white hair; rest of abdo- 
men with very short white hair; antennae and outer sides of 
tibiae rather rufous. Vertex with a transverse row of four elevated scars, the lateral ones much 
the larger; the pronotum short and broad as usual, each side with a broad, pale stripe. Wings un- 
marked; venation dark, much spotted with pale, in places with pale streaks; the cubitus out to the 
fork and the basal part of the fork almost wholly pale, the branches therefrom also mostly pale; 
in fore wings eight cross-veins before the radial sector, in hind wings seven; about seven branches 
to radial sector in each wing; posterior banksian line indicated; apical field with one series of a 
few (two to six) cross-veins; in hind wings the first anal runs into the cubital fork at basal third of 
latter; in fore wings four branches of the first anal to margin, in hind wings three such branches; 
the costals in both wings are entirely simple. 
Length of forewing — 35 mm., breadth, 8mm. Length of hindwing — 32 mm., breadth 7 mm.

The genus Centroclisis (including Neoclisis) if restricted to species with en- 
tirely simple costals has few species: from Egypt, cervina Gerstaecker, adnixa 
Navas, and lineata Navas (probably all one species); lanosa Navas from Mada- 
gascar; and punctulata Navas from Africa. ‘The latter species differs in spotted 
wings, while the others are much larger than minor.
