Antennal bristles subequal to the fleshy setae in length ; segments VIII and IX each with 

 one ventral bristle. Terminal segment with one dorsal preapical bristle, two lateral ones 

 at a greater distance from the apex and two apical small setae. 



Thorax : 585-623 (608) |x long. Pronotal ridges medially interrupted at a weakly sclerotized 

 point ; lateral pronotal sclerites small and post-tergites narrow. Proepisternum without any 

 ridge-like sclerotization. Prosternum comparatively long and narrow, 82-85 (84) fx long ; 

 posteriorly bounded by a 119-125 (122) y. long prosternal ridge. Prothoracic setae absent 

 altogether. 



Mesothorax : Prescntum 89—98 (95)(x long and 171-174 (i73)[x wide, the ratio being 1 : i-8- 

 20 (1-9) ; prescutal ridge well developed and presculal suture distinct. Scutum 91-95 (94) (x 

 long, i.e. the ratio lengths of prescutum to scutum 1 : 0-9-1-1 (10). Prealare, prealar ridge, 

 tegular, triangular plate, anterior and posterior notal wing processes well developed. Scutellum 

 70-73 (72)1* long and 159-168 (165)11 wide, the ratio being 1 : 2-2-2-4 ( 2 "3). an d its length to 

 the length of scutum 1 : 1-2-1-4 ( I- 3) '• scutellar ridge well developed. Postalare with anterior 

 and posterior ridges joined. Postnotal apophysis large. Mesopleuron : Mesopleural ridge 

 continuous above the coxal articulation. Basalare comparatively slender. Subepisternal 

 ridge well developed. Mesepisternum distinct and mesepimeron small. Later o-pleurile large, 

 with an oval membranous area. Mesosternum : Basisternum 183-195 (189) jx long and 241- 

 250 (247) (x wide ; marginal, precoxal ridges and furca well developed. Mesothoracic spiracle 

 21-24 ( 2 3)|x wide at opening, with a 46-52 (49) \x long supporting bar. Mesothoracic setae on 

 each side : One prescutal setae always present ; scutal as well as scutellar setae 2-3 (25). 

 Tegular setae always 2. Postmesostigmatal and basisternal setae absent. Metathorax : Meta- 

 postnotal sclerites ill-defined ; metapostnotal ridge absent. Metapleural ridge attenuated as 

 usual near the middle ; dorsally supporting a small pleural wing process. Precoxal ridge 

 strong and metasternal apophysis distinct. Metathoracic spiracle identical with the meso- 

 thoracic. Metathoracic setae : 4-5 (4-5) metatergal setae and one anterior metasternal seta 

 present on each side ; metapleural and posterior metasternal setae absent. 



Wings : 1 064-1 148 (no6)(x long and 420-490 (462) jx wide ; always with 2 alar setae. 

 Hamulohalterae 92 \x long and 24-27 (26) |x wide ; with one, 52-58 (55) jx long apically hooked 

 seta, the ratio its length to the length of the hamulohaltera being 1 : 1 -6-1-8 (17). 



Legs : Well developed, short and stout ; the middle legs usually shortest and the hind legs 

 longest ; the ratio length of the hind leg to the total length of body 1 : 2-1-2-2 (2-15). Coxa 

 and trochanter about 64 and 371X wide respectively ; the latter with a differentiated long apical 

 seta. Femur about 46(x wide ; that of the middle leg shortest and those of the fore and hind 

 legs subequal ; the ratio width to length of the hind femur 1 : 3-5-40 (3-8). Tibia about 24(x 

 wide ; with 2 apical spurs ; in fore leg the femur slightly shorter than the tibia, the ratio their 

 lengths being 1 : 1-2-1-4 ( I- 3)- Tarsus about 2i(x wide ; tarsal digitules apically knobbed, 

 about 37 (x long. Claw broad at base, abruptly tapering apically ; ungual digitules also apically 

 knobbed. The following table shows the lengths of the leg segments (in microns) and the 

 number of setae on each :
