NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 247 



distinct ; eyes rounded, about as broad as high ; frons very narrow, distinctly 

 narrower than the eye, with parallel sides, not prominent in profile, even at base of 

 antennae ; lunula broad ; face narrow above and widened below, with a flat, 

 triangular middle keel and rather prominent at mouth-border ; cheeks linear ; jowls 

 narrow. Antennae inserted towards the middle of the eyes, shorter than the face ; 

 3rd joint rounded at end ; arista plumose, but not broadly. Palpi not or but little 

 dilated at end, bristly ; proboscis short. Ocp. strong, numerous, acute, black ; oc. 

 very short and thin, but distinct ; 2 i. or. ; genal bristle strong. Thorax elongate, 

 with parallel sides, flat above ; chaetotaxy complete, with strong bristles ; dc. 

 placed much behind, near the line of the first p. sa. ; middle scp. as thin as the outer 

 ones ; one strong mpl. and below this a smaller one ; st. much stronger than the pt. 

 Scutellum flat above, triangular, with lateral keels, bare on the disc, with four strong 

 bristles. Abdomen ovate, not longer than the thorax, with strong bristles on sides 

 and at end. Ovipositor flat, triangular, not longer than the half of the abdomen. 

 Legs not elongated ; front femora with 4-5 strong bristles below ; middle tibiae 

 with one spur ; hind femora without bristles below ; hind tibiae with a distinct 

 posterior row. Wings proportionally narrow and long, entirely infuscated, with 

 hyaline indentations and spots. No distinct costal bristle ; stigma elongated, more 

 than three times as long as broad ; 1st longitudinal vein with stout bristles and 

 ending above the small cross- vein ; 2nd vein straight ; 3rd bristly throughout its 

 whole length, exactly parallel with the last section of the 4th ; the segment of the 

 costa between the ends of 1st and 2nd longitudinal veins only a little longer than that 

 between the 2nd and 3rd ; small cross- vein beyond the middle of the discoidal cell, 

 which is much broader at end than at base ; hind cross- vein perpendicular, a little 

 arched outwardly, about as long as its distance from the small one ; lower angle of the 

 anal cell rather short and broad, triangular, shorter than the 2nd basal cell. 



1. Ptiloniola neavei, sp. no v. 



A very distinct species on account of its entirely infuscated wings, which have 

 only a few narrow hyaline spaces. 



(J $. Length of body, 6-7 mm. ; of ovipositor, 1 mm. ; of wing, 7-8 mm. 



Head entirely reddish yellow, paler below and on the occipital swellings ; occiput 

 with a blackish horizontal stripe extending from the neck to the lower edge of the 

 eyes and forming a continuation of the dark notopleural stripe ; frons unspotted, 

 with only a narrow, black ocellar dot ; jowls unspotted ; antennae, palpi and 

 proboscis pale reddish yellow. Cephalic bristles black, except the genal bristle, 

 which is yellow ; frontal band with sparse, scattered, short hairs ; occiput below 

 with long, whitish pile. Thorax reddish testaceous on the back, pale yellowish on the 

 pleurae, these two parts being separated by the blackish, narrow, horizontal noto- 

 pleural stripe, extending from the humeri to the root of the wings ; the back rather 

 shining, with short pale yellowish pubescence ; pleurae shining, with longer whitish 

 pile. All the bristles black, but the second mpl., the pt. and the strong st. yellow. 

 Scutellum like the thorax and with the set. black. Mesophragma shining testaceous, 

 infuscated on the sides, where the hypopleural callosities are pale yellowish like the 

 pleurae. Halteres with yellowish stalk and blackish knob. Abdomen rather 

 shining, testaceous towards the middle, black on the sides and on the whole of last
