258 HETEROCERA. 
The examples received from Chiriqui agree well with Edwards's description. The 
insect is extremely close to 7. batis, and chiefly differs from it in having a row of 
spots on the outer margin of the primaries. From South-east Brazil we have speci- 
mens of 7. batis that are perfectly conspecific with English ones; the species has also 
been recorded from Japan.

2. Thyatira hersilia, sp.n. (Tab. XXVI. fig. 2.) 
Primaries dark dull brown, crossed about the middle by a number of very indistinct darker brown waved lines, 
with a spot at the base nearest the inner margin, two on the costal margin, one of elongate shape at the 
apex, one on the outer margin, and a small one at the apex, dusky white ; secondaries brown, palest at 
the base, with a row of marginal lines extending from the apex to near the anal angle, the fringe brownish- 
white ; the underside of both wings pale brown, without white markings, and each with two submarginal 
rows of darker brown lines extending from the apex to the anal angle: head, the thorax in the middle, 
and the abdomen dark brown, the sides of the thorax greyish-white, the anus pale yellowish-brown ; 
antenns, palpi, and legs dark brown. Expanse 2 inches, 
Hab. Guatemata, Capetillo (Champion). 
One specimen. 
3. Thyatira heurippa, sp.n. (Tab. XXVI. fig. 3.) 
Primaries pale fawn-colour, the costal margin broadly bordered from the base to the apex with white (edged 
with reddish-brown from the base to the middle), a large dark brown V-shaped mark extending across 
the wing from the costal margin to near the middle and here divided by a narrow white line from a 
dark band extending to the inner margin (the latter edged with white), a small V-shaped dark brown 
mark at the apex, and several rows of very minute reddish-brown spots extending from the apex to 
the anal angle, the latter whitish; secondaries dark brown, palest at the base and anal angle, the 
fringe pale reddish-fawn-colour; the underside of the primaries dark blackish-brown, with the costal, 
outer, and inner margins paler, and the V-shaped markings as above but not so distinct, that of the 
secondaries reddish-brown, both wings with two narrow waved submarginal dark brown lines extending 
from the apex to the inner margin: head and front of the thorax dark brown, the collar and base of the 
tegula white, the rest of the thorax and tegule dark fawn-colour; the abdomen reddish-brown, the anus 
fawn-colour ; palpi, antenne, and legs dark brown. Expanse 14 inch. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
This fine insect, of which only two specimens were captured, is quite distinct from 
all the known species of the genus, and it is not closely allied to any yet described. 
4, Thyatira (2) hypatia, sp.n. (Tab. XXVI. fig. 4.) 
Primaries of a pale olive-colour, much shaded with pink-brown and white, with a broken black line near the 
apex extending from the costal margin towards the outer margin but not reaching it, a black mark close 
to the anal angle, several black spots near the base, and a pinkish semicircular spot on the inner margin 
nearest the anal angle, the centre of the wing whitish; secondaries glossy pale olive-brown, with the 
outer margins broadly bordered with brown, a pinkish spot at the anal angle; both wings narrowly 
edged with black: head, thorax, and abdomen pale brown, the tegule and a few scales at the base of the 
abdomen pinkish ; (antenne and legs wanting). Expanse 12 inch. 
Hab. Panama, Bugaba (Champion). 
We include this beautiful insect in the genus Thyatira with considerable doubt ; in 
many respects it very closely resembles the species of that genus, but the palpi are longer
