Antennae : Filiform ; normally 10-segmented ; 470-653 (573) (i long, i.e. as long as, or 

 shorter than half the total length of the body (ratio 1 : 2-0-2-3, av. 2-2), and shorter than the 

 hind leg (ratio 1 : 11-12, av. 1-17). Scape 40-49 (43)^ long and 37-46 (43)10. wide at base ; 

 always with 4 h.s. Pedicel 55-67 (64)0. long and 31-40 (37);x wide ; with 26-36 (31-7) f.s., 

 10-18 (12-3) h.s. and a sensillum placodeum. Flagellum : Segment III club-shaped and longest 

 of all (the ratio lengths of segments III to X 1-2-1-4, av - I- 3 : x ) '• the segment about 231* 

 wide, i.e. the ratio its width to its length 1 : 2-9-3-8 (3-4). Segments IV to X cylindrical and 

 about 21 (x wide, the ratio width to length of segment IX being 1 : 2-1-3-3 ( 2- 7)- The lengths 

 of the flagellar segments and the number of setae on each are given in the following table :

Antennal bristles easily distinguishable ; segments VIII and IX each with one ventral 

 bristle. Terminal segment with 3 preapical bristles, the dorsal of which is about half as long 

 as the others ; the segment also with two capitate subapical sensory setae and one apical hair- 

 like seta. 



Thorax : 418-600 (540) \i long. Prothorax : Pronotal ridges medially constricted at a weak 

 point. Lateral pronotal sclerites moderately large and post-lergites narrow. Proepisternum 

 with a ridge-like dorsal margin. Prosternum triangular, 31-46 (38)11 long ; prosternal ridge 

 85-104 (96) (x long. Prothoracic setae on each side : Medial pronotal setae 0-2 (1-3) ; lateral 

 pronotal setae 0-3 (i-i) ; post-tergital setae absent, and antespiracular dorsal setae 1-3 (20). 

 Antespiracular ventral seta always one, and prosternal setae 1-3 (1-7). Prothoracic disc pores 

 on each side : Medial pronotal pores 2-5 (3-1) ; lateral pronotal pores 1-3 (2-1) ; antespiracular 

 dorsal pores 1-2 (1-7). Prosternal pores 1-2 (i-i). 



Mesothorax : Prescutum 61-89 (76)1* long and 104-143 (131)11 wide (ratio 1 : 1-6-1-8, av. 

 1-7) ; presculal ridge strong and prescutal suture well marked. Scutum heavily sclerotized 

 antero-laterally, and with a median longitudinal narrow membranous area ; 85-125 (1 13) pt 

 long, i.e. the ratio length of prescutum to scutum 1 : 1-3-1-5 (146). Pleural structures typical 

 of the family. Scutellum pentagonal, 46-64 (58) (i long and 85-116 (104)0. wide, the ratio being 

 1 : 1-7-1-9 (i-8) ; subequal to half the length of the scutum, ratio 1 : 1-8-2-1 (1-9). Postalare 

 with well separated anterior and posterior postalar ridges. Postnatal apophysis large. Meso- 

 pleuron : Mesopleural ridge interrupted above the coxal articulation ; basalare stout. Sub- 

 episternal ridge well developed. Mesepisternum and mesepimeron distinct ; lateropleunte 

 narrow. Mesosternum : Basisternum 122-174 (152)11 long and 146-201 ( 1 80) |i wide ; marginal 

 and precoxal ridges well developed. Mesothoracic spiracle 18-21 (19)11 wide at opening, with a 

 37-43 (40) (i long supporting bar. Mesothoracic setae on each side of the median line : Prescutal 

 setae 5-9 (6-3) ; scutal setae usually 8-1 1, although 13 setae were found on one side of one 

 specimen (av. io-o) ; scutellar setae 3-6 (3-4). Tegular setae 3-5 (4-1). Postmesostigmatal 

 setae 4-9 (6-i), in a latero-ventral group. Basisternal setae 7-15 (9-9). Mesothoracic pores : 

 Mesospiracular pores 0-1 (o-8) ; one postmesostigmatal pore almost always present submedially 

 on each side, but none or two pores may occur on one side (av. 10). 



Metathorax : Metapostnotal sclerites and metapostnotal ridge well developed. Metapleural 

 ridge attenuated at the point of origin of the metapleural apophysis. Precoxal ridge well 

 developed and metasternal apophysis well defined. Metathoracic spiracle similar to mesothoracic. 

 Metathoracic setae on each side : Metatergal setae 3-5 (4-1) ; metapleural setae 0-2 (o-8).
