CILEA.—TACHINUS. 309 
that the name he proposed has priority, and I accept this declaration till evidence to 
the contrary shall be produced. Although only four or five species are known, the 
genus has a very wide distribution, occurring in Europe, Madagascar, Caffraria, and 
Ceylon. ‘The species found in Europe also occurs in North America, and Mr. Champion’s 
discovery of a species in Guatemala is the first indication we have obtained of the genus 
being really endemic in the western hemisphere. ; 
1. Cilea fenestrata. 
Subdepressa, nitida, levigata, nigra; elytris pone scutellum plagis duabus testaceis, pedibus (antennisque ?) 
fuscis ; abdomine ad apicem longius nigro-setoso. 
Long. 33 millim. 
Hab. Guatemata, San Juan in Vera Paz (Champion). 
Three basal joints of antenne fuscous yellow; the fourth joint darker; the others 
broken off. Thorax large, rather broader than the elytra, rounded at the sides, so that 
the hind angles are obtuse; base not at all sinuate. Elytra with smooth and polished 
surface, like the thorax entirely without punctuation, straight at the sides, but the hind 
margin externally much sloped, so that the exterior hind angles are very obtuse. Hind 
body strongly margined at the sides, quite black, shining, with only a few very fine 
punctures. 
The only individual found is in a very broken and decayed condition; it is a female, 
and is remarkable for the great length of the terminal spines of the last segment; the 
same segment is also ornamented with very long and conspicuous black sete.

This is a genus of sixty or seventy species, and is one of the characteristic features of 
the Staphylinid fauna of the boreal and temperate portions of the Palearctic and 
Nearctic Regions; it is largely represented in North America. The four species here 
described are of feeble development ; they indicate a greater extension of the genus to 
the south in the northern part of the western hemisphere than has been hitherto 
recorded, but in the Old World a similar feeble species has been found at a great 
elevation in the Pamir. A species reputed to belong to the genus has been described 
from Chili, and it is possible that others may be discovered at great elevations in the 
more northern portions of South America. 
1. Tachinus meridionalis. (Tab. VII. fig. 10.) 
Debilis, subdepressus, nitidus, niger; prothoracis marginibus lateralibus flavescentibus, elytris fusco-testaceis, 
circa scutellum et ad margines nigricantibus ; pedibus flavis, tibiis tarsisque fusco-testaceis. 
Long. 43 millim.
