SAUNDERSIA. 23 
Hab. Guatemaa, Purula, San Gerdénimo, Cerro Zunil 4000 to 5000 feet (Champzon) ; 
Costa Rica, Rio Sucio, Cache, Volcan de Irazu 7000 feet (Rogers). 
Several specimens of both sexes. 
At first sight this species offers a striking resemblance to Dejeania corpulenta, 
Wiedem., and D. plumitarsis, v. d. Wulp ; but on account of the total absence of the 
long straight palpi, there cannot be any doubt that it is a Sawndersia and not a 
Dejeania. The spines of the second and third abdominal segments not only exist at the 
hind margin, as in the above-mentioned species of Dejeania, but also in the middle. 
Two male specimens, one from Rio Sucio and one from Irazu, differ from the others 
in their smaller size (10°5 millim.) ; and also in the less dense pilosity of the abdomen, 
on account of which the red ground-colour and the black dorsal spots are more conspi- 
cuous; moreover, they have the pilosity of the thoracic dorsum blackish, and the basal 
joints of the antenne more obscure in tint. As I cannot find any other difference, | 
think these specimens are merely a variety of the same species. 
6. Saundersia nigropilosa, sp.n., ¢ (2%). 
Closely allied to S. rufopilosa and differing as follows :— 
The pilosity of the abdomen black and much shorter; the entire surface of the fourth segment, except the 
front border, densely beset with spines ; the first segment laterally with several (instead of two) spines ; 
the pilosity of the thorax obscure; the hairs and bristles of the coxe and femora, without exception, 
black, the bristles round the terminal joints of the tarsi, on the contrary, yellow; the elongate yellow 
pulvilli brownish at their truncated extremity. 
Length 12-5 millim. 
Hab. Muxico, Cordova (Hége); Costa Rica, Rio Sucio (Logers). 
The description is taken from a single male specimen from Cordova. ‘Two female 
examples from Costa Rica differ from the other in being a little smaller (11 millim.) ; 
but show all the above-mentioned characters, with the exception that the black dorsal 
spots on the abdomen are less conspicuous and somewhat divided into two. I believe 
they are referable to the same species. 
7. Saundersia unicolor, sp. n., c. 
Black; head yellowish ; thorax on the front side with some grey tomentum ; abdomen densely beset with 
spines; antenne and legs black; tegule and wings greyish-brown. 
Length 11 millim. 
Head pale yellow; front narrowed behind, dark cinereous, only the orbits yellowish; frontal band rutous, 
laterally bordered with black ; frontal bristles long, hardly descending beneath the root of the antenne ; 
the outward bristles and those on the vertex more robust; face prominent towards the oral margin ; 
vibrissee surmounted by some shorter bristles; beard and pilosity of the cheeks and of the occiput 
yellowish. Antenne black; second joint with some bristles on the upper part; third joint as long as the 
second, rounded at the end. Thorax, scutellum, abdomen, and legs black; on the front side of the 
thoracic dorsum some grey tomentum, with longitudinal black lines, of which three in the middle, placed 
close together, are the most conspicuous ; abdomen densely beset with spines. Front femora outwardly 
with grey tomentum ; the legs with many bristles, which on the outside of the middle tibie are long and
