hypopygium with the ninth tergite (Plate XLIX, 267) having a slender median lobe; 
truncated at the apex, with a conspicuous chitinized claw on either side of the tergal 
region. [Berl. Ent. Ztschr., vol. 7, p. 292. 1863.] (Plate XLV, 214, wing.) 
T. caloptera Loew 
(Two species are apparently confused under this name; true caloptera has the bases 
of cells Mi, M2, and M; pale, as figured, and the male hypopygium lacks the clawlike 
appendage on either side of the median lobe of the ninth tergite.) 
Smaller, wing of male 23 mm. or !ess, and paler-colored; prescutal stripes not heavily mar- 
gined with brown; antennae longer, extending nearly to the base of the abdomen, bicolor- 
ous; abdominal tergites without a dark brown sublateral stripe; wings without a con- 
spicuous yellow spot in cell 1st Ri; cells M1, M2, Ms, and Cu hyaline basally; male 
hypopygium with the ninth tergite (Plate XLIX, 264) having a broad median lobe, 
rounded at the apex; no lateral claws on the tergal region. [Berl. Ent. Ztschr., vol. 7,

12. Antennae short, with only the basal segments of the flagellum distinctly bicolorous; 
wing pattern more clear-cut, the costal stripe broader and darker brown, vein Cu 
and the basal deflection of Ci with a broad dark brown seam. [Berl. Ent. Ztschr., 
vol. 7, p. 291. 1868.] (Plate XLV, 216, wing; Plate XLIX, 265, ninth tergite.) 
T. bella Loew 
Antennae longer, with all except the terminal segments of the flagellum distinctly 
bicolorous; wing pattern less distinct and rather poorly defined, the brown stripes 
and seams much paler. [Berl. Ent. Ztschr., vol. 7, p. 290. 1863.] (Plate XLV, 217,

13. White obliterative streak before the wing cord passing beyond cell 1st M2 and almost 
reaching the wing margin; male hypopygium having the region of the ninth tergite 
without a brush of bristles on its lateral part. [Berl. Ent. Ztschr., vol. 8, p. 56. 1864.] 
T. fraterna Loew 
White obliterative streak before the wing cord ending in the extreme base of cell M,; 
male hypopygium having the region of the ninth tergite (Plate X LIX, 263) with a brush 
of long, stiff, reddish bristles on its lateral part. [Ent. Syst., vol. 4, p. 285. 1794.]

to T. tricolor but may be a good species. The description of 7’. vitrea calls for a tes- 
tacecus abdomen with a brown lateral stripe, while in 7’. tricolor the abdomen is con- 
colorous thruout.).
