Front wings: 10-11 antenodals, 5-6 postnodals, internal triangle 
of two cells, two posttriangular rows almost to the wing-margin, 
three marginal cells. 
Hind wings: 7 antenodals, 6-9 postnodals, inner side of triangle 
a little, but distinctly, nearer the base than is the arculus, two post- 
triangular rows (in one hind wing of Teuscher’s 9 the upper post- 
triangular cell reaches across th§ entire width of the field, then 
follow the two rows) to the level of the origin of the subnodal 
sector, increasing to 7-8 marginal cells. 
Total length 37 mm., abdomen 27.5. Hind wing 26-27, its 
greatest width 8. Pterostigma 1.7-2. Apps. .6 mm., hind tibia 4.5. 
One female, Brazil, Heyer, the original type of Hagen, the last 
five segments of the abdomen lost. One female, Canta Gallo, 
Brazil, Dr. Teuscher, Thayer Expedition. Both in the M. C. Z. 
Heyer’s female is evidently a younger individual, as the colors 
throughout are pale. The only bases for doubting the specific 
identity of the two specimens are I believe the pterostigma and the 
membranule. On the other hand the thorax pattern, the markings 
of the abdomen, and the neuration agree, while the difference in 
the coloring of the wings is not greater than is to be found within 
such species as celaeno and hemichlora. 
The head and the thorax pattern much resemble those of marmo - 
rata Hagen (tenuis Karsch), the chief difference in the latter being 
that the black point on the metepimeron of musivct is in marmorata 
connected with the stripe on the second lateral suture forming with 
that stripe a fork whose branches diverge dorsad. Musiva differs 
otherwise from marmorata in having on the hind wings only one 
submedian cross-vein, two posttriangular rows, and the inner side of 
the triangle not in the prolongation of the arculus, and longer pale 
stripes on the abdominal segments. 
Miatliyria flavescens Kirby, Ann. mag. nat. hist., (6), vol. 19, p. 
600, pi. 13, fig. 2, June, 1897, seems from the description and figure 
to be a Macrothemis , and Mr. McLachlan writes me that he thinks 
it is undoubtedly so. In that case it seems close to musiva , differing 
chiefly by the “broad green band on each side, obsolete in front” 
on the thoracic dorsum. Further study will be necessary to deter¬ 
mine the question of identity or distinctness. 
11. Macrothemis inacuta sp. nov. 
A detailed description and figure have long been in readiness for 
publication in the Proceedings of the California academy of science.
