181 



92-107 (95) y. long. Prothoracic setae : Medial, lateral pronotal, post-tergital and antespiracular

Mesothorax : Prescutum 58-70 (64)^ long and 122-140 (131)^ wide, the ratio being 1 : 19- 

 2-3 (2-0) ; laterally and posteriorly bounded by the prescutal ridge and the prescutal suture 

 respectively. Scutum 49-61 (52) ^ long, i.e. the ratio lengths of prescutum and scutum 1 -1-1-4 

 (1-2) : i. Prealare, prealar ridge, triangular plate and the mesopleural structures well developed. 

 Sculellum 61-70 (67)^ long and 113-131 (122)^ wide, i.e. the ratio 1 : 1-6-2-0 (i-8), and its 

 length to the length of the scutum 1-1-1-4 ( I- 3) : * '• scutellar ridge strongly developed. 

 Anterior and posterior postalar ridges anteriorly joined. Postnotal apophysis well developed. 

 Mesopleuron : Mesopleural ridge continuous above the coxal articulation ; basalare slender. 

 Subepisternal ridge distinct. Mesepisternum and mesepimeron well defined. Latero-pleurite 

 comparatively large. Mesosternum : Basisternum 116-134 (i25)[x long and 192-211 (2oi)(i. 

 wide ; marginal, precoxal ridges and /urea well developed. Mesothoracic spiracle 21-24 [ 22 )v>- 

 wide at opening, with a 43-49 (46) (x long supporting bar. Mesothoracic setae on each side : 

 Prescutal setae 0-1 (0-4) ; scutal setae usually 1-2 and occasionally 3 (av. i-6) ; scutellar setae 

 1-2 (1-9). Tegular setae 2-3 (i-8). Postmesostigmatal, and basisternal setae absent. Meta- 

 thorax : Metapostnotal sclerites small ; metapostnotal ridge absent. Melapleural ridge 

 attenuating near the middle as usual ; melapleural wing process missing. Metepisternum and 

 metepimeron small. Precoxal ridge weak and metasternal apophysis small. Metathoracic 

 spiracle similar to the mesothoracic. Metathoracic setae on each side : Metatergal setae 3-4 

 (3-4) ; melapleural setae absent. Anterior metasternal seta 0-1 (o-6) ; posterior metasternal 

 setae absent. 



Wings : 910-1050 (994) \i long and 308-392 (350) (i. wide ; always with 2 alar setae. The 

 hamulohalterae and the suspensorial sclerites absent. 



Legs : Moderately long and stout ; the fore and the middle legs of subequal length and 

 shorter than the hind legs ; the ratio length of hind leg to the total length of body 1 : 1-5-1-8 

 (i-6). Coxa about 55 and trochanter about 3i[i wide respectively ; the latter with one, about 

 46(x long differentiated apical seta. Femur about 401A 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 : 4-3-4-7 (4-5). Tibia about 24^1 wide ; with 2 apical spurs ; in fore leg the femur slightly 

 shorter than the tibia, the ratio their lengths 1 : 1-2-1-4 ( x '3)- Tarsus about i8(j. wide ; tarsal
