Taeniostola tripunctaln, new species 



Plate 20 



A large light yellow species allied to T. Uinhata Hendel 

 from Formosa, h\\\ at once distinguished from it by 

 the parallel-sided Irons, the three or more inferior 

 fronto-orbital bristles, the comparatively long mesono- 

 tuni, which has one pair of black longitudinal stripes 

 and three distinct black spots along the posterior 

 margin, and the comparatively narrow wings. 



Male. — Head as wide as thorax, 1.4 times as wide 

 as long, nearly as long as high. Frons (pi. 20, fig. 4) 

 yellow, orbits more or less whitish tomentose, an 

 ill-defined small brownish-j^ellow spot at middle of 

 anterior half, with very sparse brown pubescence, 

 almost flat, as wide as one eye, parallel-sided with 

 straight lateral nuu'gins; v^ertical calli distinctly shining, 

 narrow and long, not attaining middle of frons; lunule 

 rather narrow, shming, with brownish ui)i)er margin, 

 this color extending nearly to oral margin along inner 

 edges of facio-orbits; ocellar triangle small, blackish 

 brown, a distinct shining transverse carina. Face (pi. 20, 

 fig. 3) nearly as high as wide, not hollowed, distinctly- 

 covered by whitish tomentum, with a rather distinct 

 straight median longitudunil carina broadened below 

 and very shortly ])roduced forward toward the oral 

 margin; antennal grooves broad, conspicuous, distinctly 

 extendhig to oral margm; orbits disthict, narrowed at 

 about middle, inner margins sharj); vibrissa! edge more 

 or less with some very fine j)ubescence. Back of head 

 (pi. 20, fig. 2) strongly swollen, upi)er portion flat with 

 very sparse yellow i)ubcscence; occiput with very fine 

 brovraish lateral margins; cheeks strongly swollen, 

 wider than 1/5 the eye height, a broad, very shallow 

 genal groove, with short black pubescence above the 

 genal bristle. All bristles black, comijaratively weak: 

 fronto-orbitals 2:3 or 4, superiors stronger than in- 



feriors, upper conspiciujusly shorter than lower, inferior 

 directed inwaid or distinctly crossing; ocellars fine, 

 rather long, more or less divergent; inner verticals 

 strongest and longest, more than twice as long as 

 outer; postverticals ahnost parallel, slightly shorter than 

 outer verticals, a short bristle (occipital) behind the 

 inner verticals; genal bristle nearly as long as ocellar, 

 somewhat stronger. Antennae (pi. 20, fig. S) light yellow, 

 shorter than face, inserted at a point just below middle 

 of eye; second segment nearly 2/5 as long as tliird, 

 with a distinct black median bristle, apical margin with 

 one row of numerous brown bristly hairs; third segment 

 more tluiii twice as long as wide, gradually and dis- 

 tinctly narrowed toward a round apex, dorsal margin 

 concave, witli a whitish minute pubescence; arista 

 black with basal segments yellowish, short-plumose. 

 Pal])! (pi. 20, fig. 9) light yellow, comparatively long, 

 2.5 times as long as wide, conspicuously narrowed at 

 base, dorsal margin nearly straight, ventral margin 

 strongly convex, apex rounded, with rather long sparse 

 bristly hairs on venti-al half. 



Thorax light yellow, shining, more than twice as 

 long as wide, slightly longer than high. Mesonotum 

 (pi. 20, fig. 6) sliglitly longer than wide, somewhat 

 white tomentose, covered by a yellowish depressed 

 pubescence intermixed with brown oblique pid)esceiice, 

 one pair of black narrow longitudinal streaks from inner 

 corners of hunieral calli to roots of dorsocentrals in- 

 terrupted at inner ends of sutures, posterior margin with 

 three conspicuous black spots; humeral calli with 

 l)rownish bristly hairs on anterior border; notopleural 

 calli more or less brownish; scutellum about twice as 

 wide as long, disk rounded, without marginal carinae, 

 lateral borders perpendicular. Pleura (pi. 20, fig. 5) 

 paler than notum, nearly bare, with very sparse brown 

 rather erect ])ubescence; pro thorax with long j'ellowish 

 pubescence, without bristle; sternopleuron with rather 

 numerous long brown hairs on lower border and with 

 two black long bristly hairs at posterior corner; meta- 

 pleuron with a black spot just above root of haltere; 

 mesophragma concolorous with scutellum; postiu)tum 

 sometimes more or less reddish yellow, with a brownish 

 median longitudinal stripe on one specimen. All bristles 

 black: inner scapulars parallel or hardly divergent, 

 slightly weaker than outer pair; humerals, notopleurals, 

 and presuturals nearly the same length, but posterior 

 notopleiu-als more or less shorter; dorsocentrals situated 

 just behind level of anterior supra-alars, slightly shorter 

 than prescutellars, the latter situated on a line connect- 

 ing imier posterior supra-alars, which are longer than 

 remaming supra-alars; apical scutellar pair almost 

 always ])arallel, but their tips more or less directed 

 inward, distinctly shorter than basal pair, which is as
