to be emended and modified thus:—Third joint of the antenne as long as or a little 
longer than the second; one or more genal bristles; macrochete of the second and 
third abdominal segments at the hind margin only, or at the hind margin and in the 
middle *. 
In the collections before me I find the three following undescribed species :— 
1. Macrochetz of the second and third abdominal segments 
in the middle as well as on the hind margin; rufous 
species. . . . . . 
re rufina, v. d. Wulp.

only on the hind margin ; black-coloured species, with 
black legs 2 2 1 ee ee ee ee

1. Trichophora rufina, sp.n.,¢ @. (Tab. II. figg. 15; 15 a, head in profile.) 
Rufous, including the antenne and legs; a single genal bristle ; macrocheete on the middle of the second and 
third abdominal segments; bristles of the legs rufous; wings yellowish at the base and along the basal 
part of the costa. 
Length 8°5 millim. 
Face perpendicular, a little prominent at the oral margin, in the male pale yellow, in the female bright 
ochraceous; cheeks without pile, but with a single bristle; above the vibrissee one shorter bristle, and 
beneath them four bristles; pilosity of the occiput yellowish: front rather broad, with a ferruginous 
median band, which is narrowed behind; frontal bristles forming on both sides a single row, and scarcely 
descending beneath the base of the antennw. Eyes bare. Antenne fulvous; second joint on the upper 
part with some bristles ; third joint as long as the second, but broader and truncate at the end (in the . 
female specimen it is infuscated at the extremity); arista black, indistinctly jointed, thickened nearly to 
the end. Thorax yellowish-cinereous () or ochraceous (2), with four black stripes placed at equal 
distances, the exterior ones somewhat broader; scutellum of the same colour as the thorax; macrocheete 
of the thorax abundant, four longer and stouter ones at the hind margin of the scutellum. Abdomen 
scarcely longer than the thorax, fulvous, more or less transparent ; in the male the fourth segment, with 
the exception of the front border, is black; in the female this black colour is confined to the anus, but 
somewhat extended in a dorsal stripe; on the second segment two macrochete in the middle, two on the 
hind margin, two on each side; on the third segment two in the middle, two on each side, and an entire 
row at the hind margin; fourth segment with many macrochate. Legs fulvous, the last four joints of 
the tarsi brownish or even dark brown; bristles rufous, short on the front tibie, very long and stout on 
the outside and at the end of the middle tibia. Tegule fulvous; wings cinereous, brownish-yellow at the 
base and at the beginning of the costa; small cross-vein placed if anything a little before the middle of 
the discal cell; apical and posterior cross-veins slightly curved. 
Hab. Guatemaua, Cahabon (Champion); Costa Rica, Cache (Rogers). 
A female specimen from the former, a male from the latter locality. 
2. Trichophora trisetosa, sp.n.,2. (Tab. II. figg. 16; 16, head in profile.) 
Shining black, the fourth abdominal segment rufous; thorax cinereous, with four black stripes; head white ;. 
* In this sense the North-American species described by me under the name of Schineria ruficauda (Tijdschr. 
voor Ent. x. p. 146. 18) is a Trichophora, and not a Cyphocera, to which genus it is referred by Léw and 
Osten Sacken.
