area of the ventral preocular depression ; 3-4 (3-8) on each side of the ventral arm of the 

 medcranial ridge. Head disc pores : Dorsal pores usually absent, although one pore was found 

 on one side of a few specimens near the base of the antennae (av. 03). 



Antennae : Filiform ; 10-segmented ; 610-769 (705)^1 long, i.e. subequal to half the total 

 length of the body (ratio 1 : 1-8-21, av. 19), and subequal to the hind legs (ratio 1 : o-8-i-i, 

 av. 095). Scape 46-55 (52) u. long and 46-49 (47) y. wide at base ; always with 4 h.s. Pedicel 

 61-70 (66)(i long and 37-43 (40)11 wide ; with 19-29 (231) f.s., 10-14 ( I2- i) h.s. an d a sensillum 

 placodeum. Flagellum : Segment II I club-shaped, about as long as segment X, both being the 

 longest (ratio approximately 1:1); segment III about 29(1 wide, the ratio its width to its 

 length being 1 : 2-5-3-2 (29). Segments IV to X cylindrical and 24-27(1 wide, the ratio width 

 to length of segment IX being 1 : 2-4-2-9 (2-7). The lengths of the flagellar segments and the 

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

each \\ ith 



one ventral bristle. 



Terminal 



segment with 3 preapical bristles and two much smaller ones near the base of the segment ; 

 terminal segment also with a pair of capitate subapical sensory setae ami one apical hair-like seta. 



Thorax : 532-707 (722)11 long. Prothorax : Pronotal ridgis with the usual median interrup- 

 tion. Lateral pronotal sclerites and post-tergites small. Proepisternum with a ridge-like dorsal 

 margin. Prosternum 43-58 (52) (i long and comparatively narrow ; posteriorly bounded by 

 the transverse, 92-110 (104) [i long prosternal ridge. Prothoracic setae on each side : Medial 

 pronotal setae 1-2 (17) ; lateral pronotal setae 1-3 (21) ; post-tergital setae almost always 

 absent, but one seta was found on each side of one specimen (av. 01 h.s.) ; antespiracular 

 dorsal setae 2-4 (2-9). One antespiracular ventral seta always present. Prosternal setae 2-4 

 (2-5). Prothoracic pores on each side : Medial and lateral pronotal pores 1-3 (averages 2-2 and 

 2-1 respectively) ; antespiracular dorsal pores 1-2 (i-i). Prosternal pore usually one, but 

 sometimes two or none at all on either side (av. 11). 



Mesothorax : Prescutum 92-119 (io4)ji long and 131-168 (153)11 wide (ratio 1 : 1-4-1-7, 

 av. 1-5) ; laterally bounded by the prescutal ridges and posteriorly by the prescutal suture. 

 Scutum heavily sclerotized antero-laterally, with a medial longitudinal narrow membranous 

 area ; 110-137 (i28)(i long, i.e. the ratio lengths of prescutum to scutum 1 : 1-1-1-3 ( I-2 ). 

 Prealare, prealar ridge, triangular plate, anterior and posterior nolal processes well developed. 

 Scutellum 61-73 (70)11 long and 98-125 (n6)(i wide, the ratio being 1 : 1-6-1-7 (i'°5) and the 

 ratio lengths of scutellum to scutum 1 : 1-7-2-0 (i-8). Postalare with well separated anterior 

 and posterior ridges. 



Mesopleuron : Mesopleural ridge with a short interruption above the coxal articulation ; 

 basalare stout and subepisternal ridge well developed. Later opleurita narrow. Mesosternum : 

 Basisternum 162-204 ( x 86)|i long and 168-235 (207)11 wide ; marginal and precoxal ridges well 

 developed. Mesothoracic spiracle about 2 1 (i wide at opening, with a 40-46 (43) (i long supporting 

 bar. Mesothoracic setae on each side : Prescutal setae 4-7 (5-7) ; scutal setae 8-12 (io-i) ; 

 scutellar setae 1-2 (i-i). Tegular setae 3-5 (4-2). Postmesostigmatal setae in two separable 

 groups, a latero-ventral cluster of 8-12 (9-6) setae behind each spiracle, and 1-3 (1-7) setae 

 submedially, forming with their partners of the other side a transverse irregular row. Basi- 

 sternal setae 10-16 (12-7). Mesothoracic disc pores on each side : Mesospiracular pores 1-2 

 (1-5) ; one postmesostigmatal pore usually present submedially, but sometimes absent on one 

 side (av. o-8).
