transverse band across the area of the ventral preocular depression ; 4-6 (5-1) in a longitudinal 

 row on each side anteriorly. Head disc pores : One dorsal pore always present near the base 

 of each antenna. Antennae : Filiform ; 10-segmented ; 744-903 (82i)y. long, i.e. longer 

 than half the total length of the body (ratio 1 : 1-4-1-6, av. 15), and longer than the hind legs 

 (ratio 1-2-1-4, av. 1-3 : 1). Scape 43-49 (46)0. long and 46-52 (49) u. wide at base ; usually 

 with 4 h.s. (occasionally with 5 or 6, av. 4-2). Pedicel 58-73 (67) [* long and 40-46 (43)0. wide ; 

 with 20-36 (27-2) f.s., 5-1 1 (7-6) h.s. and a sensillum placodeum. Flagellum : Segment III 

 club-shaped ; subequal in length or somewhat shorter than the terminal segment (ratio 1 : i-i-i, 

 av. 1 03) ; about 3i[x wide, i.e. the ratio its width to its length 1 : 2-8-3-4 (3-0). Segments 

 IV to X cylindrical, and about 24 u. wide, the ratio width to length of segment IX being 

 1 : 3-3-8 (3-4). The following table shows the lengths of the flagellar segments and the number 

 of setae on each :

Antennal bristles slightly stouter than the fleshy setae. One ventral bristle present on each 

 of antennal segments VIII and IX. Terminal segment with 3 subapical bristles and 2 much 

 smaller, lateroventral ones, at a greater distance from the apex. The segment also with two 

 capitate subapical sensory setae and one apical, hair-like seta. 



Thorax : 456-570 (524)^ long. Prothorax : Pronotal ridges with the usual interruption 

 medially ; lateral pronotal sclerites and post-tergites distinct. Proepisternum with a ridge-like 

 dorsal margin. Prosternum subtriangular, 37-52 (43) [z long ; prosternal ridge 92-113 (104) y 

 long. Prothoracic setae on each side of the median line : Medial pronotal and lateral pronotal 

 setae 0-1 (av. 0-2 and 0-3 respectively) ; post-tergital setae absent ; antespiracular dorsal setae 

 2-4 (2-7). One antespiracular ventral seta always present. Prosternal setae 1-3 (1-9). 

 Prothoracic disc pores on each side : Medial pronotal pores 1-3 (1-9) ; lateral pronotal pores 

 1-3 (2-1) ; antespiracular dorsal pore always one. Prosternal pores usually one, but sometimes 

 either side may be with 2 pores or none at all (av. 0-9). 



Mesothorax : Prescutum 70-95 (79) y. long and 1 10-134 ( I22 )u- wide (ratio 1 : 1-4-1-7, av. 

 1-5). Prescutal ridges well developed and prescutal suture distinct. Scutum with heavy antero- 

 lateral sclerotizations, and with a medial longitudinal narrow membranous area ; 89-113 

 (i04)u. long, i.e. the ratio lengths of prescutum to scutum 1 : 1-1-1-4 ( I- 3)- Prealare, prealar 

 ridge and triangular plate well developed. Scutellum 49-64 (58) y. long and 85-104 {98) y. wide, 

 i.e. the ratios its length to its width 1 : 1-6-1-9, av. 17, and its length to the length of the 

 scutum 1 : 1-6-2, av. i-8. Postalare with well separated anterior and posterior postalar ridges. 

 Mesopleuron : Mesopleural ridge interrupted above the coxal articulation ; basalare strong. 

 Other pleural structures typical of the family. Mesosternum : Basisternum 122-153 ( I 37)( jL 

 long and 171-214 (189) y wide ; marginal and precoxal ridges strong. Mesothoracic spiracle 

 18-21 (20) (x wide at opening, with 40-46 (43) y long supporting bai . Mesothoracic setae on each 

 side : Prescutal setae 3-5 (3-6) ; scutal setae 7-1 1 (8-i) ; scutellar setae 2-4 (2-8). Tegular 

 setae 4-6 (4-9). Postmesostigmatal setae 5-8 (5-9), occurring in a lateral group behind each 

 spiracle. Basisternal setae 6-9 (7-3). Mesothoracic disc pores : 1-2 (1-2) mesospiracular pores, 

 and 0-1 (0-9) postmesostigmatal pores present on each side of the median line. 



Metathorax : Metapostnotal sclerites and metapostnotal ridge well developed. Pleural ridge 

 attenuated near the middle, where a pleural apophysis originates ; pleural wing process small. 

 Episternum, epimeron, precoxal ridge and metasternal apophysis distinct. Metathoracic spiracle 

 similar to the mesothoracic one. Metathoracic setae on each side : Metatergal setae 2-5 (2-6) ;
