236 Mr. R. Mcleachiant on the 
lines, and two black bands connected at the intermediate legs. 
Pectus black. 
Legs red ; spines black, those on the tibie long and divari- 
cate ; apex of tarsal joints and tips of claws black. 
Abdomen bright red, marked with black as follows :—A 
large quadrate spot at the base of the first segment, somewhat 
emarginate posteriorly, and a small spot on either side on the 
posterior suture ; a narrow ring at the apex of segments 2 to4 5 
a broad ying at apex of segment 5; the whole of segments 
6 to 8 (excepting a broad ring at base of 6 occupying about 
one sixth of its length, a narrow ring at apex of 7 and 8, and 
the sides of all three, broadly); a large irregular spot on 
each side of segment 9. 
g. The margin of tenth segment is very oblique on 
either side, and with a sudden small triangular median 
excision. Superior appendages longer than the segment, 
black (red at the base internally), stout, the apices slightly 
incurved ; internally the basal portion is much dilated for more 
than half their length, and at the apex of the dilated portion 
is a slight excision, leaving a formation as of two indistinct 
blunt teeth. Inferior appendages scarcely one half shorter, 
slender, slightly incurved, red, blackish at the tips. 
9. Unknown. 
Length of abdomen, ¢ 34 millim.; length of posterior wing 
23 millim.; expanse 51 millim. 
Oahu (Llackburn, one male, No. 67). Taken in company 
with Megalagrion oceanicum (vide post.), and sent by Mr. 
Blackburn under the same number. There is very great 
general resemblance ; but the size, neural characters, &c. 
readily separate the two ; the anal parts, although very similar, 
also present differences. 
Agrion (?) calliphya, n. sp. 
Wings narrow, tinged with yellow ; petiolated nearly up to 
the basal postcostal nervule in both pairs. Pterostigma lozenge- 
shaped, surmounting rather more than one cellule, reddish 
brown. Quadrilateral elongate, its upper edge about half the 
length of the lower in both pairs. Postpterostigmatical cellules 
irregular, distinctly in two rows in the posterior wings. Six- 
teen or seventeen postcubital nervules in the anterior wings, 
thirteen or fourteen in the posterior. Four cellules between the 
quadrilateral and the nodus. 
Head and thorax black. Abdomen red. 
Front wholly reddish yellow, excepting a very narrow black 
line before the rhimarium. Postocular spots red, small, and 
nearly linear.
