Thora.r. — The mesonotnm bears three rows of bristles, besiiles a basal row 

 which extends down to the second pronotal spine, and a number of additional small 

 bristles on the back and the sides. Tliere is, in fact, onl}- a small lateral area bare 

 of bristles. The mesopleura bear seven, and the metepisternnm five or six bristles. 



Abdomen. — Segments I to VI have no obvions distinctive characteristics. 

 The)' bear two rows of bristles on the tergites with an incomplete third row on the 

 first tergite and one or two dorsal bristles in front of the rows on the other tergites. 

 The sternites of segments III to VI have, in the cj, usually a row of six bristles 

 on the two sides together, and two to sis additional bristles, the ? bearing, as a 

 rnle, eight bristles in the row and fonr to six in front of it. 



Legs. — In the hindtarsns the second segment bears one apical bristle, which 

 reaches to the apex of the third segment ; the fourth segment is twice as long as it

is broad, and the fifth segment has fonr lateral bristles. The proportional lengths 

 of the hindtarsal segments are : <S . 41, 3(1, 19, 12, 20 ; ? , 42, 31, 20, 12, 20. 



i 1 0(1 ijiecl Segments. — i. The eighth sternite is broadly ronnded, and bears on 

 each side six to nine bristles, of which three (more rarely only two) are long. The 

 clasper (text-fig. 23) terminates in a broad and short process which is divided by a- 

 very shallow apical sinus into two lobes, the sinus being deeper on the inner side 

 of the clasper than on the onter surface. The upper lobe is rounded and bears 

 about a dozen bristles at the edge. The ventral angle of this lobe is produced on 

 the inner side of the clasper into a short, subtrnncate, strongly chitinised projection. 

 The lower lobe is very obliquely truncate, and bears a long bristle at the ventral 

 angle and another on the onter snrface. The movable process (F) has a characteristic 

 shape. Its ventral margin is rounded from the base to tliree-ibnrths its length and 

 then incurved, the apical ventral angle of the finger distinctly projecting downward.
