Plate 12 



Fem.vle. — Head nearly as wide as tliDrax, nearly 

 twice as wide as long, a little longer than high. Frons 

 (pi. 12, fig. 2) light orange yellow, with very few sparse 

 inimite black hairs which become rather conspicuous 

 on the elevated pale-colored and shining orbits, as wide 

 as eye, witli straight and j)arallel lateral margins, rather 

 flat but sliglilty elevated above eye; lunule somewhat 

 semicii'cular, narrower than half as wide as frons, color- 

 ation similar to or])ils and sliglitly shining; ocellar 

 triangle small, blackish, just behmd it there is no 

 transverse carina; vertical calli very short but well 

 defined, moderately elevated, their posterior margins 

 obliquelj' truncated and not extending behind eye- 

 angle. Face (pi. 12, fig. 3) slightly paler than frons, 

 comparatively narrow, with lateral marguis curved 

 outwards; orbits well defined with rather deep sulci, 

 moderately broadened beneath; antennal grooves very 

 shallow, hardly traceable; the vibrissal j)ortion furnished 

 with some black, very short, irregularly du'ected setae 

 which extend above to the inferior portion of para- 

 facialia. Head in profile (i)l. 12, fig. 1) longer tlian half 

 the lieiglit, with face slightly hollowed about at middle; 

 back of head light yellowish, moderately swollen, with 

 tlie superior portion nearly fiat and iiTegularly blackish 

 brown, inferior portion with black sparse long hairs 

 extending onto the cheeks; cheeks more or less whitish, 

 moderate in size, with a distinct genal groove. All 

 bristles black: fronto-orbitals 1 : 3, the superior one 

 longest and directed externoposteriorly, the three 

 inferiors gradually shortened anteriorly and directed 

 inlerno-anteriorly; ocellars as long as upper inferior 

 fronto-orbital but weaker, moderately divergent and 

 directed forwards; inner verticals longest, nearly 

 parallel, outer verticals nearly as long as the lowest 

 inferior fronto-orbital; postverticals weak, parallel, 

 directed slightly forward; the inner occipital bristles 

 Ijresent but weak; genal brrstle shorter than the inferior 

 fronto-orbitals; occipital row rather conspicuous, com- 



posed of a])out 11 bristles extending to near midtlle of 

 eye. Eye black, microscopically pubescent, in jjrofile 

 ratlior ol)li()uc, half as wide as long, with anterior 

 margin strongly convex and i)osterior margin rather 

 straight, distinctly narrowed l>eneath; when seen from 

 above wider than lialf the length, with anterior corner 

 distiiu'tly narrowed and posterior corner obtuse; when 

 seen from front the inner margin S-like ciu'ved, with 

 both superior and inferior corners distinctly narrowed. 

 Antennae (pi. 12, fig. 4) light yellow, inserted nearly at 

 mitldle of eye, conspicuously shorter than face; first 

 segment very short, with some black bristly hau's on 

 ajiical margin; second segment nearly as long as its 

 apical width, with a long black median bristle; along 

 externo-aj)ical margin there are black sparse bristly 

 hairs which become longer at the inferior apex; third 

 segment fully 3 times as long as preceding, gradually 

 narrowed toward round apex; arista 1.5 times as long as 

 third segment, very shortly plumose, black with Itasal 

 third light j^ellow. Palpi (pi. 12, fig. o) light reddish 

 yellow, very short, hardly half as wide as long, with apex 

 broadly rounded, furnished with many long black 

 Ijristly hairs. 



Thorax as wide as head, longer than wide or a little 

 longer than high, strongly shining. Mesonotum (pi. 12, 

 fig. 6) brown pubescent, as long as wide, moderately 

 convex, dark castaneous brown, with two pairs of 

 light reddish-yellow broad longitudinal bands, the 

 median one extending from behind anterior margin to 

 middle of metazona, the other along just outer margins 

 of the median bands, extending slightly behind the 

 posterior ends of latter but not reaching anterior ends, 

 distinctly interrupted at sutures; humeral calli rather 

 small, light reddish yellow; notojileural calli moderately 

 elevated, dark castaneous brown; wing-bases light 

 yellow. Scutellum 1/3 as long as mesonotum, longer 

 than half the basal width, flat, light yellow, with 

 somewhat darkened basal portions of lateral borders 

 descending obliquely below. Pleura (pi. 12, fig. 7) 

 light brownish yellow, with the superior third, including 

 inferior portion of humeral callus, light yellow and 

 middle space from posterior portion of mesopleuron to 

 metapleuron castaneous brown, almost free of pubes- 

 cence except on brownish-yellow portion, where there 

 is a very sparse short blackish pubescence; sterno- 

 pleuron comparatively large, the ventral border fur- 

 nished with some black long bristly hairs. All bristles 

 black: scapulai's two paii's; j)resuturals well developed; 

 dorsocentrals just anterior to level of single pair of 

 anterior supra-alars; prescutellars nearly in a line 

 connecting the two outer pairs of posterior supra-alars; 

 scutellars two ])airs, very long, the apical ones parallel; 

 notopleurals two pairs; mesopleurals 1, but followed
