ANNALES MUSEI NATIONALIS HUNGARICI. 
1905. 
A COLLECTION OF PHORIDÆ FROM PERU. 
By Charles T. Brues. 
Through the great kindness of Dr. K. Kertész of the Hungarian 
National Museum, I have been enabled to examine a very interesting 
collection of Peruvian Plioridæ belongi.g to the Museum. 
Although it numbers only fourteen specimens, 8 species are repre¬ 
sented, 5 of which are undescribed. Of the previously described species, 
Trineura montana Brues belongs to a nearctic group and no doubt ex¬ 
tends southwards along the mountains into Peru. Another belongs to a 
distinctly neotropical portion of the genus, and is quite similar to a 
common species on the Islands of St. Vincent and Grenada in the West 
Indies. Another was described originally from North America, and a 
third one from Europe. 
Of the new species, one is closely related to certain holarctic types, 
and others are distinctly neotropical. In all, three genera are represented. 
Aphiochæta peruviana n. sp. 
Male. Length 2*5 mm. Ptobust, black with brownish yellow legs. 
Head black, front wide, opaque, dusted with whitish pollen. Ocellar 
tubercle and frontal furrow very distinct. Setæ all very stout, proclinate 
ones four in number, with an additional quite small median pair. Lower 
corner of cheeks with a short row of forwardly curved bristles. Palpi 
yellow, their bristles only moderately strong. Antennæ rather small, 
deep black, with a pubescent arista. Thoracic dorsum hairy, moderately 
shining, with one pair of dorsocentral macrochætæ and four equally 
strong marginal scutellar bristles. Abdomen dull black, stout and tape- 
ring. First five segments narrowly margined posteriorly with yellow; 
the sides of the second segment with a tuft of black bristles, and the 
entire surface sparsely covered with more or less erect hairs. Hypopygium 
small, the overhanging lamella blunt at tip. Legs stout, the hind femora 
considerably swollen; front and middle tibiæ distinctly setulose exter¬ 
nally, the hind ones with a row of very strong setulæ. Wings large, the 
veins strong, faintly tinged with brownish, the veins piceous. Costa 
reaching distinctly beyond the middle of the wing, its cilia rather short,
