NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 245 



head in profile view and obviously rounded. Occiput flat ; frons flat, with parallel 

 sides, prominent only above the antennae, with the middle band thinly pilose. Cheeks 

 linear ; jowls very narrow. Antennae inserted towards the middle of eyes, as long 

 as the face ; 3rd joint not much longer than broad, rounded at end ; arista long and 

 thin, bare. Face shorter than the length of the frons, with a broad but flattened 

 keel extending to the base of the antennae, which are thus rather broadly separated. 

 Mouth-opening less broad ; palpi dilated at end, projecting, thickly pilose but not 

 bristly ; proboscis exceedingly incrassated (whence the generic name), cylindrical, 

 with broad and fleshy terminal flaps, as long as the length of lower border of head. 

 Cephalic bristles well developed ; ocp. long, thin, acute, black ; pvt. diverging ; 

 oc. long but thin ; 2 s. or. and 2 i. or. ; mouth-borders bristly on sides. Thorax 

 short and broad, rather flat on the back ; chaetotaxy complete, but the bristles rather 

 thin ; middle scp. short but distinct ; dc. placed much behind, very near the prsc. , 

 about on the line of the first p. sa. ; 2 mpl. ; st. weaker than the pt. Scutellum 

 broad, convex above, rounded on the sides, thinly pilose on the disc, with three pairs 

 of bristles of nearly equal size. Abdomen broadly ovate, with separated segments, 

 thinly pilose, without distinct bristles. Legs short and stout ; front femora with long 

 and thin bristles ; middle tibiae with a single spur ; hind tibiae with no distinct row. 

 Wings proportionally short, rounded outwardly, with no distinct costal bristle. 

 Auxiliary vein distinct and callose at end ; costal cell rather broad ; 1st longitudinal 

 vein ciliated ; stigma a little longer than broad ; 2nd longitudinal vein straight, 

 3rd with very long bristles throughout its whole length, ending near the apex of wing, 

 parallel with the last section of the 4th ; discoidal cell twice as long as the second 

 posterior cell, much broader at end than at base, the small cross- vein placed at its 

 middle ; hind cross- vein perpendicular, gently arched outwardly ; lower angle of 

 the anal cell produced into a very long and narrow point, very like that of Dacus. 

 The wings are wholly infuscated, with hyaline indentations and spots. 

 Type : the following new species : — 



1. Baryglossa histrio, sp. nov. 



A strange insect, very distinct from any other Ethiopian Trypaneid owing to its 

 very thickened proboscis, as well as its peculiar body- and wing-pattern. 



(J. Length of body, 5 mm. ; of wing, 5 mm. 



Head entirely yellowish grey, without any dark pattern, except a small, black 

 ocellar dot. Antennae entirely yellowish, the 3rd joint a little darker ; arista 

 fuscous, with yellowish base. Palpi and proboscis wholly yellowish. All the cephalic 

 bristles black, like those of thorax and scutellum. Thorax entirely yellowish grey, 

 opaque, paler on the pleurae, darker on the back, yellow before the scutellum ; 

 there are on the back two indistinct longitudinal darker stripes, one on each side of 

 the middle line. The hairs of thorax are dark yellowish, those on the back rather 

 long. Mesophragma brownish, shining below. Scutellum yellow, opaque, with a 

 black terminal spot, which is rounded in shape and fills up the space between the 

 a. set. Halteres pale yellowish. Abdomen yellow, opaque, with a very striking black 

 pattern, which extends to the sides and apex and is formed by a very small spot at 

 hind border of 1st, by a broader one occupying all the sides of the 2nd, by a still 

 broader on 3rd segment, which may be said to be entirely black with a rounded yellow
