 conspicuously longer than ])osterior, as long as jjresulu- 

 ral; dorsocentrals conspicuously behind a line con- 

 necting anterior sujjra-alars, which are tiearly as long 

 as dorsocentrals; prescnitellars on the level of inner 

 posterior supra-alars, which are as long as pi'escutellars; 

 apical scutellars parallel, distinctly shorter than hasal 

 pair; mesopleurals two, ])ler(ii)lcural directed supcro- 

 posteriorly, sternoi)leur:ii ihrcctetl dorsally, all the 

 same lengtli. 



Abdomen (pi. Iti, lig. 7) more or less purplish, hardly 

 tomentose, black pubescent, posterior marginal bristles 

 rather short; second terguni with rather numerous 

 erect hairs on lateral borders; sixth tergum a little 

 shorter than preceding, with three pair's of long black 

 nuirginal bristles; basal segment of ovipositor black, 

 dei)ressed, with lateral marginal caruiae, as long as 

 sixth abdominal tergum, second segment castaneous; 

 the venter with coloration similar to that of dorsum. 



Wing (pi. ]G, fig. 1) shorter than body, nearly twice 

 as long as wide, with apex narrowly rounded; costal 

 vein attaining end of m, costal sjiine distinct and as 

 long as basal bristle; Ri gradually curved anteriorly 

 apically; R2+3 very slightly undulate; R4+5 more or 

 less undulate at basal half of apical section, bristled 

 from base to beyond r-m; m nearly parallel with R4+5 

 ai)ically; r-m conspicuously beyond middle of IM2, 

 straight, neai-ly pcriiendicular; m-cu almost straight, 

 not parallel with r-m; pterostigma nearly 2/3 as long as 

 second costal cell, apex pointed; anal cell distinctly 

 shorter than basal cell, but with long inferior prolonga- 

 tion. Basal two-thirds blackish brown, somewhat paler 

 at extreme base, middle third of second costal cell, base 

 of R,, a triangular indentation just beyond pterostigma, 

 and a rather faint narrow oblicjue streak from apex of 

 rs to end of anal vein, hyaline; apical third hyaline, with 

 a narrow blackish-])rown streak from middle of apex of 

 R5 to near apex of R, along costa, then bent nearly at 

 right angles to tip of Cu. Halteres brownish, with base 

 of stalk yellowish. 



Legs moderate in length, blackish jjubescent. Foreleg 

 (pi. 16, fig. 10) reddish yellow, consjjicuously shorter 

 than other pairs; femora a little longer than tibia, 

 externodorsal margin with one row of black sparse 

 long bristly hairs, apical half of dorsal margin with long 

 black bristly hairs, externoventral margin with one row 

 of about 6 black, very long bristly hau's; tibia as long as 

 tarsus; first tarsal segment as long as four following 

 segments together, yellowish brushlike bristles on 

 internoventral surface conspicuously longer toward 

 base. Midlegs (pi. 10, fig. 11) light brownish yellow, 

 femur black, longest; femur as long as tibia, ventral 

 surface with a distinct longitudinal groove, apical 



halves of external and internal margins with black 

 short bristly hairs, tibia more or less darkened toward 

 base, with one black apical spur, in addition to two 

 black sjjurlike bristles on external and one on internal 

 apical margins; tarsus distinctly shorter than tibia, 

 first segment a little longer than the four following 

 segments together, brushlike biistles on internoventral 

 surface rather short and brown. Hindleg (pi. 16, fig. 12): 

 femur slightly longer than tibia, dorsal surface with one 

 pair of long black bristly hairs before apex, externo- 

 ventral margin with one row of moderately long, black, 

 bristly hairs; tibiae with one row of black bristlj^ hau's 

 along externodorsal margin, ventral apex with one 

 distinct, bristly ban-; first tarsal segment distinctly 

 longer than the four following segments together, 1/2 

 as long as tibia, with yellowish brushlike bristles on 

 internoventral surface.

Plate 17 



Near P. formosanus Shiraki, l)ut easily distinguished 

 by the nonstriped mesonotum, the uniforndy colored 

 abdomen, the comparatively short third antennal seg- 

 ment, the basally bore arista, the wing-pattern, and 

 other characters. 



Female. — Blackish, legs yellowish. Head narrower 

 than tiiorax, nearly twice as wide as long, higher than 

 long. Frons (pi. 17, fig. 2) distinctly narrower than 

 one eye, very slightly narrowed anteriorly, with straight 

 latersd margins, flat reddish brown, very slightly white 

 tomentose, very sparsely blackish pubescent at mitldle, 

 where an ill-defined longitudiiud groove extends from 

 tiji of l)lack ocellar triangle to nonshining lunule; 

 vertical calli narrow and long, somewhat shining, a 

 distinct transverse carina between lateral ocelli and 

 posterior ends of vertic^d cidli. Face (pi. 17, fig. 3) 

 nearly as long as lower width, brown, moderately whitish 

 tomentose, rather fiat iMit. very sliglitly hollowed at 

 about middle, antennal grooves hardly traceable, 

 orbits very narrow, epistoma \ery short. Back of head
