NO. 2015. SOME NEW MOTH-FLIES— KNAB. 105 



Three specimens bred from larvae in the water at the leafbases of 

 epiphytic bromeliads. Larvae were found in different plants on dif- 

 ferent occasions, but proved difficult to rear. The forking of the 

 upper branch of the second vem beyond the middle of the wing, as it 

 occurs in this species, has been supposed to be a characteristic peculiar 

 to the subfamily Phlebotominae; but the presence of a well-developed 

 long seventh vein clearly places it in the Psychodinse. 



PSYCHODA TRICOLOR, new species. 



Female. — Black, variegated with white and ocherous yellow. An- 

 tennae long, slender, pale, the nodes elongate and rather small, with 

 dense whorls of coarse silky white hairs. Palpi stout, rather long, 

 less than half as long as the antennae, densely clothed with shaggy 

 black scales. Thorax brownish luteous ; dorsum clothed in front with 

 erect brownish white scales, posteriorly with black ones, the two 

 intermingling toward the middle, a few white-tipped scales posteriorly. 

 Abdomen densely clothed with long erect black scales, some yellow 

 scales formmg tufts on anal appendages. Wings pale grayish hyaline, 

 broadly lanceolate, over twice as long as wide, coming to a rather 

 sharp point at apex of third vein; upper branch of second vein forked 

 before middle of wing; vestiture black with white marginal spots; 

 fringe broadly golden before apex on both outer and inner margins, 

 the extreme tip black; costal vestiture dense, black from base to 

 uppermost branch of second vein and involving two small white 

 patches; fringe on inner margin very long, black from base to fourth 

 vein; longitudinal veins with the black scales denser at extreme 

 apices, producing the effect of black spots, just before them some long 

 white scales which project in such a way as to give the effect of white 

 marginal spots on the cells. Legs with shaggy black scales; knees 

 silvery white scaled ; some of the tarsal joints with narrow white rings. 



Length. — Bod}'- about 2.5 mm.; wing 2.7 mm. 



Locality. — Coscajar River, Panama, February, 1909 (A. H. Jen- 

 nings). Three specimens bred from larvae in water at leaf bases of 

 epiphytic bromeliads. 



Type.—CsLt. No. 15935, U.S.N.M. 



A very similar species has been bred from larvae in the hquid held 

 by the flower bracts of Calatliea discolor. On account of the simi- 

 larity of appearance and of habits it is best described here. 



PSYCHODA INCOMPLETA, new species. 



Male. — Black, variegated with white, similarly marked to P. tri- 

 color. Antennae long, dark, the nodes globose, piceous, the stems 

 slender, brownish; hairs of whorls long and rather dense, blackish. 

 Occiput, thorax, and abdomen densely clothed with long erect sooty 

 scales. Wings pale grayish hyahne, broadly lanceolate, over twice
