tubes, and phallic flanges.

Wing: Costal margin straight, without dila-

tion, surface slightly brownish; costal vein yellow setose basally. R 4 recurrent vein about as long as cell base. Crossvein r-m at apical 1/4 of cell d.

Legs: Bristles and setae yellow except sparse black setae on femora apically; metathoracic femora

with 2-3 yellow posteroventral bristles basally. Tibiae brownish-yellow, narrow apex black, vestiture mostly yellow, apical bristles black. Tarsi reddish basally, becoming reddish-black or black apically; bristles mostly black, 1 yellow bristle on prothoracic tarsi; dense yellowish setae ventrally.

Abdomen: Reddish-brown, wide sides of tergites 1-6, tergite 7 and sternites 1-7, white tomentose

entirely, white extends dorsally along apical margin on tergites 1-5; tergites 1-6 brown tomentose dorsally. Setae mostly yellowish, long on sides of tergites 1-3 and sternites 1-3; sparse, short, brown setae on tergites 2-6 and 8 dorsally; tergite 8 whitish setose laterally and sternites 6-7 apically.

Terminalia (Fig. 40-42): Reddish, mostly black setose. Epandrium twice as long as wide, squared

apically, with thin flanges dorsally and notch dorsoposteriorly. Gonostylus narrow, apex broadly rounded. Phallic flanges produced, angular dorsally; aedeagus angled at 90 degrees. Gonocoxite anteriorly narrowed on apical 1/3, apex pointed, setae long, moderately dense. Female. Body 14.0- 14.1mm; wing 9.5-10.8 mm. Head: Mystax mostly yellow, 5-6 black bristles dorsally; frons mostly black setose; postocular bristles yellow. Thorax: Anterior scutal setae about as long as pedicel; 2 lateral and 2 dorsocentral bristles yellow. Wing: Crossvein r-m just beyond middle of cell d.

Legs: Tarsi with only black bristles. Abdomen: Tergites 1-7 mostly brown tomentose dorsally, wide sides

and apical margin of 3-6 yellowish tomentose, mostly yellow setose, tergites 2-3 or 4 brown setose medially, mostly brown on 5-7 dorsally; sternites 1-7 yellowish, setae whitish or yellowish, long on sternites 1- 3, shorter beyond. Terminalia: Black, slightly shorter than apical 3 segments, 3.2 mm, at middle 1/6.5 as wide as long. Types. CUBA: Sta. [Santa] Fé, Is. de / Pinos [Isla de la Juventud], Cuba / 6.ix.1928 ~ C.S. Bruner, Y.L. Brouclé ~ S.W. Bromley collection (holotype m, USNM) . Paratypes: Columbia, Is. / de Pinos [Isla de la Juventud], Cuba / 7.ix.1928 ~ CS Bruner, Y.L. Brouclé (1 f, USNM) ; Zaza d. Media / Cuba (2 f, AMNH) . Etymology. Latin pina , genitive, refers to the former name of the type locality, Isla de Pinos. Distribution. Cuba , Isla de la Juventud; September .

Remark. Efferia pina is distinguished from

congeners by the characters in the key and the

combined characters of the male terminalia (Fig.

40-42).
