g. The supplementary material is older and demonstrates that the colour-differences of the type from infecta 
are due to its immaturity. In these, the metallic-green metepisternal stripe reaches down to the spiracle, 
the abdominal segments are dark brown or blackish, pterostigma present, surmounting one cell, or slightly 
more or less, basal red on the hind wings occupying the entire area from the median vein backward to 
the first row of cells below the postcosta and outward to the distal end of the quadrilateral and, on the 
oldest two, also the costal space to beyond the level of the quadrilateral, tips of the hind wings with a 
red spot, of the front pair slightly brownish, wings more or less smoky throughout; three of the six hind 
wings have but two rows of cells between the lower sector of the triangle and the hind margin, although 
in two of these the two rows are interrupted by three cells, -

Occurred in the woods along a stream, in company with H. cru-ntata, but much less 
abundant, Sept. 12, 1906.

CORA (p. 48). 
Two additional and undescribed species from our region have come to light. In 
both of them the nodus, on the front wings, lies almost midway between the base and 
the proximal end of the stigma, the second sector of the triangle is trifurcate, and 
there is no dark band. ‘They differ from each other in size, in the relative extent of 
dark and pale colours on the thorax, and in C. chirripa possessing one, or only a 
rudiment of one, supplementary sector between the first and second sectors of the 
triangle, while C. skinnert has three such supplementary sectors. 
3. Cora chirripa, sp. n. 
$. Head black, a rounded orange spot between each lateral ocellus and the antenna of the same side, the 
following pale yellow or blue: @ spot on the frons below each antenna, genze, a wide marginal stripe on 
the nasus, labrum, outer surface of the mandibles, submentum, mentum, and busal half of median 
labial lobes. 
Thorax predominantly pale blue with the following black markings: front and hind prothoracic lobes and a 
median stripe connecting them on the middle lobe; anterior mesothoracic border, a mid-dorsal thoracic 
stripe which is twice as wide (15 mm.) above the inferior fork of the mid-dorsal carina as below that 
fork, and which again widens at the level of the superior fork of the carina so as to reach outward to the
