anterior margin irregular, weakly sclerotized, and partly overlapped by metathoracic fold ; 

 postnotal apophysis and postalare well developed, the latter densely reticulated distally. Meso- 

 postphragma short, with shallow emargination. Mesopleuron. Mesopleural ridge strong, not 

 interrupted above coxal articulation ; pleural apophysis and pleural wing process well developed, 

 the latter connected with episternum by a narrow basalare. Subalare small. Episternit»i 

 without polygonal reticulation ; subepisternal ridge broadening ventrally, but below mem- 

 branous cleft indistinct and only marked by a band of dark sclerotization. Epimeron very 

 small. Lateropleurite partly bounded anteriorly by an extension from marginal ridge. Basi- 

 sternum large, about 163 fx wide and 91 [x long, i.e. 1 26-1 72 (average 1-52) times longer than 

 membranous area of scutum ; with strong median ridge and bounded by strong marginal and 

 precoxal ridges ; without setae. Fnrca well developed. Mesothoracic spiracle with well 

 developed peritreme ; postmesospiracular setae absent. Tegula small, membranous bulge with 

 a small weak sclerite posteriorly and with 1—5 (average 2-8) h.s. Third axillary wing sclerite 

 with a small, rounded ventral projection at its base. Additional sclerite weak, but distinct. 

 A ntemetaspiracular setae absent. 



Metathorax. Metanotum with posterior margin thickened throughout ; suspensorial sclerite 

 absent. Postnotum large, transverse, weak or interrupted medially. Metatergal setae : one 

 h.s. on each side. Pleural ridge considerably reduced, extending only a short distance above 

 coxal articulation. Episternum reduced to a small subtriangular plate ; epimeron produced 

 posteriorly. Metathoracic spiracle similar to mesothoracic one. Dorsospiracular setae absent . 

 Postmetaspiracular setae 6-14 (average 10) f.s. and 0-2 (average 07) h.s. Metasternal plate 

 weak, but more heavily sclerotized around anterior margin. Anterior metasternal setae : 

 16-23 (average 19) f.s. and no h.s. ; posterior metasternal setae : 7-19 (average 13) f.s. 



Wings hyaline ; long (910-1050, average 969 |x) and narrow (2<>5-36o, average 336 u, wide), 

 ratio width to length being 1 : 280-301 (average 2 90) ; alar lobe and alar setae absent. 

 Halteres absent. 



Legs short and moderately slender, all 3 pairs subequal in size, fore legs being only slight Iv 

 shorter ; ratio length of hind leg to body length is 1 : 1-89-2-01 (average 198). Length of

Coxae each with 10-17 f.s. and 10-18 h.s. ; fore coxa without coxal bristles ; apical seta long, 

 about as long as trochanter. Trochanters 21-24 V- wide ; with 6 oval sensilla, 7-12 (average 9) 

 f.s. and 7-9 (average 7-6) h.s., the latter including 2 minute setae near basal ridge, one small 

 seta on outer margin and a long apical seta which, on the fore trochanter, is 1-7-2-2 (average 

 1 -9) times as long as width of trochanter. Femora of medium width (30-32) jx, ratio width to 

 length of hind femur being 1 : 41-50 (average 4-6) ; each with 8-16 f.s. and 9-17 h.s. Tibiae 

 17-23 (x wide, ratio width to length of hind tibia being 1 : 9-1-11-6 (average 105) ; each with 

 20-39 h.s. and 8-22 f.s., the latter about 1 \ times longer than width of tibia ; apical spur about 

 the same size on all tibiae. Tarsi 19-21 u. wide, hind tarsus 4-0-4-3 (average 42) times longer

Segments I-VII : tergites represented by a weak sclerite on or near anterior margin of each 

 segment ; sternites consisting of a weak transverse sclerite on segments II— III, a small sclerite 

 on each side of V and VI, and a transverse plate on segment VII. Caudal extension of segment
