new Species of Odonata. 25 
excisions, the lower of which is filled in by a bright pale 
yellow oblong space ; posteriorly the bands are bordered with 
brown beneath ; on the“sides there are rudiments of post- 
humeral blackish bands, with three black spots in the median 
area, two others on the margin of the pectoral area, and, again, 
others and a fine black longitudinal line on the pectus itself. 
Legs yellow; on the femora externally are two black lines, 
fine, separated by the pale ground; tibiz black externally ; 
tarsi and spines black. Abdomen bronzy black above, 
shading into dark brown towards the apex (the ninth and 
tenth segments probably whitish pruinose in life) ; sutures of 
the third to seventh segments with a yellowish ring; first 
segment yellowish at its base, and the second with a yellow 
excision on either side in its middle; sides and beneath 
yellowish, with a blackish ring at the sutures. 
d. Tenth segment with a semicircular excision on its 
posterior edge, furnished with minute black denticulations. 
Superior appendages pale yellow, black at base and apex, 
longer than the tenth segment, the apices regularly incurved ; 
externally there are three or four fine black teeth on the 
apical portion ; internally are three nearly equidistant strong 
teeth, the basal broad and very acute, its lower edge black, 
the second also acute but rather less strong, the third (forming 
the apex of the dilated inner portion) obtuse; beyond this is 
a slight constriction before the cylindrical apical portion, 
which is obtuse at the tip. Inferior appendages short, 
scarcely reaching to the basal tooth of the superior if viewed 
from above, distant, conical, and black, furnished with a tuft 
of hairs at the tip directed inwardly ; viewed from beneath 
these appendages are broad at the base, the edge excised, so 
that the two appendages appear as if separated by a broad 
semicircular space. 
2 unknown. 
Length of abdomen (cum append.) 313 millim. ; expanse 
of wings 42 millim.; length of posterior wing 20 millim. 
Hab. Delagoa Bay. One male. 
Perhaps allied to L. pallida, Rbr., but it can scarcely be 
the undescribed male of that speeies. Possibly allied to the 
eastern L. premorsa, Selys, by the laciniate dorsal bands of 
the thorax. 
Lestes simulatria, sp. n. 
Wings hyaline. Pterostigma smoky brown, not more 
than twice as long as broad, surmounting two cellules. ‘Ten 
postnodal nervules in the anterior wings
