frontal bristles short, descending as far as the second antennal joint; vibrisse accompanied by some 
shorter bristles. Antenne rufous; second joint with black bristles; third joint three times as long as

pleure light grey; scutellum yellowish-rufous. Abdomen conical, yellowish-rufous ; first segment black 
in the middle; second and third segments with a black dorsal band, which is a little enlarged on the 
hind margin of the second segment, and on the third is united with the black posterior border, both 
these segments having a narrow white front margin; anal segment whitish in front, black for the rest, 
the anus itself rufous; macrochete are only at the hind margins of the last two segments, a lateral one 
also on the second segment. Legs rufous, the tibiz brownish, the tarsi black ; coxe densely clothed with 
a whitish pile; hind tibia outwardly with a row of short bristles, and with some longer bristles on the 
inner and outer sides at the middle; foot-claws and pulvilli short. Tegule whitish. Wings hyaline,

posterior cross-veins curved. 
Q. Face and cheeks of a pure white: the front yellowish, as broad as the eyes; the third antennal joint 
blackish towards the tip; the pilosity of the thorax shorter, and the black lines more conspicuous ; the 
abdomen, including the anal segment, rufous, with a similar black pattern to that of the male; the hind 
femora blackish towards the tip, and the middle and hind tibie nearly as black as the tarsi. 
Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (4. H. Smith). 
A male specimen from the latter, a female from the former locality. 
Closely allied to 7. relicta, but differing by the rufous colour of the abdomen and 
of the frontal band. 
6. Telothyria fimbricrura, sp. n., 3. 
Black; the abdomen partly with yellowish tomentum ; macrochete very short; hind tibie outwardly fringed 
with bristles. 
Length 7:5 millim. (one of the examples not more than 5-°5 millim.), 
Head pale ochraceous, sometimes the face and cheeks more whitish; front narrowed behind, scarcely as broad 
as the eyes; frontal band black, narrower than the lateral portions; frontal bristles descending as far as 
the end of the second antennal joint; eyes descending to the vibrisse. Antenne black; second joint 
bristly ; third joint four times as long as the second; arista thickened in its proximal half. Proboscis 
black; palpi rufous. Thorax and scutellum shining black, sometimes the thorax anteriorly greyish with

hind tibise outwardly fringed with bristles of equal length; foot-claws and pulvilli short. Tegule

apical cross-vein straight; posterior cross-vein slightly curved. 
Hab. Mexico, Venta de Zopilote 2800 feet and Amula 6000 feet, both in Guerrero 
(H. H. Smith).
