vein, reaching below to the second vein; a broad apical brown 

 band, fused with the costal border and reaching the hind mar- 

 gin of the wing ; a whitish apical lunule between ends of second 

 and fourth veins ; the 2 cross-veins have also broad dark margins, 

 the dark margination of the hind cross-vein forming a preapical 

 band. 



46. Trigonometopus bakeri sp. nov. 



Somewhat allied to the preceding species, showing also 2 pairs 

 of orbital bristles, but well distinguished by the unicolorous yellow 

 legs, long and thin brown arista, and different color pattern of 

 head and wings. 



Length of body, 5 mm. Head yellow; frons with a very nar- 

 row middle longitudinal brown stripe; a small black spot be- 

 tween antennae and eyes ; face retreating, wholly yellow, without 

 black stripes, the lateral carinas only being narrowly brown; 

 cheeks with a short black stripe just below the eye. Antennae 

 short, wholly yellow, the third joint rounded at the apex; arista 

 brown, very long, hair-like, short pubescent. Mesonotum and 

 scutellum as in the preceding species, but with the brown stripes 

 broader, the notopleurals being almost fused with the externals. 

 Halteres with brown knob. Abdomen dark yellow, lighter at the 

 base; segments with a black hind border which is broadened 

 laterally; genitalia small, yellowish; venter pale, bristles black. 

 Legs wholly whitish yellow, without any distinct dark marking; 

 tarsi darkened at apices; front femora like the preceding, with 

 3 or 4 very long bristles beneath. Wings narrow and long ; third 

 and fourth veins parallel; cross-veins less approximate; distal 

 portion of fourth vein once and a half as long as the preceding, 

 without stumps. The brown of the costal margin fills up the 

 costal cell, and, beginning at the base, is dilated to the fourth 

 vein, after the hind cross-vein ; there is no hyaline apical lunule ; 

 the cross-veins are very narrowly bordered with fuscous. 



Genus LONCHAEA Fallen. 



This collection includes very numerous species of this im- 

 portant genus, partly reared from different kinds of fruits by 

 Professor Baker. None of these species are at all similar to 

 any of those described by Kertesz, Meijere, or Lamb. I present 

 here a table separating the species, remarking that all of them 

 agree in the following characters: eyes bare; cheeks narrow; 

 antennae reaching the epistome; legs entirely black.
