TELEBASIS. 117 
separating the middle from the hind lobe; a metallic-green mid-dorsal thoracic band whose width on 
each side of the carina is about equal to half the distance from the carina to the humeral suture; an 
obscure transverse apical ring on segment 3; dorsum of segments 4—7 and of 10 shining black, but the 
apex of 7 is red and 4—7 have each a narrow, transverse, basal, medially-interrupted, yellow ring; legs 
pale yellow, femora with a superior black stripe. 
Hind margin of the prothorax convex, entire, very slightly flattened medially. 
Abdominal segment 10 less than half as long as 9, apical margin with a wide shallow excision. 
Superior appendages very short, about one-third as long as segment 10, black ; viewed from above, rectangular, 
wider than long, touching each other along the median line ; in profile subglobular. Inferiors as long as 
segment 10, reddish; in profile, about twice as high at base as the superiors, thence tapering to an acute 
apex which is curved upward; seen from below, each appendage is somewhat curved toward its fellow, 
abruptly narrowed on its inner side at half its length so that the apical half is but half as wide as the 
basal half, apex obliquely truncated so that the outer angle is the more acute. 
Pterostigma brown, paler immediately within its surrounding veins, surmounting one cell, its distal end 
shorter and less oblique than the proximal end. 
Q. Differs from the male as follows :—Brownish-yellow replacing the red; a short yellow streak near each 
posterior ocellus directed toward the antenna of the same side; an obscure stripe on the basal haif of 
each side of segment 2, and for almost the entire length of each side of 3, where they are confluent with 
the apical ring; apical half (perhaps more) of 7 and all of 10 brownish; a mid-dorsal, basal, black spot 
on 8, and a larger one on each side of 9 at base, 10 half as long as 9, its apical margin cleft medially 
almost to base. Appendages pale, not quite as long as segment 10, projecting backwards as far as 
do the palps of the genital valvules. 
Dimensions.—Abdomen, ¢ 23'5-25°5, 9 25; hind wing, g 15-16°5, 9 16°5 mm. 
Hab. Muxico, Teapa (H. H. Smith: 2 3,1 2). 
These individuals were taken in January; all have some pruinosity on the thoracic 
sterna and at the bases of the legs, and the smaller male also on the superior 
appendages. 
The bright colours have suggested the specific name from xcoAXwmerne, said to have 
been employed by Isocrates and Aristotle in the sense of ‘a dandy.” 
2. Telebasis griffinii. (Tab. V. figg. 31, 32.) 
Erythragrion griffinii, Martin, Boll. Mus. Zool. Torino, xi. no. 240, p. 2 (1896) '. 
Q (hitherto undescribed). Differs from the male as follows: face yellowish; prothorax obscure brownish, with 
an ill-defined spot on each side of the middle lobe, and a central spot on the hind lobe, black ; dorsum of 
abdominal segments 1-10 shining black, narrowed at apices of 8 and 9, the anterior ones with a greenish 
reflection, 3-7 with a narrow, transverse, basal, medially-interrupted, yellow ring, sides of 1-8 pale 
greenish ; 10 less than half as long as 9, its apical margin cleft along the mid-dorsal line for half the 
length of the segment. Appendages slightly shorter than segment 10, straight, pale brown ; palps on 
the genital valvules projecting farther backward than the appendages. 
Dimensions.—Abdomen, ¢ 23, 2 24; hind wing, ¢ 15°5, 9 16-17 mm. 
Hab. Mexico, Teapa and Rio Grijalva (H. H. Smith: 9 3,5 2); Panama, Darien 
(Dr. Festa*). 
M. Martin’s type was larger (abd. 25, hind wing 16 mm.), had 11 postcubitals on the 
front wings (here 8-10) and the upperside of the quadrilateral on the front wings half 
as long as the lower side (here less than half). Otherwise, his description applies quite 
well to these specimens from Teapa, which were taken in January and February.
