as in front of tlieiu, tlR're are dorsiilly on each side several other long bristh's whieh 

 give the insect the appearance of having a mane. A similar arrangement of 

 bristles is fonud on the first abdominal tergite. The mesonotnm bears four or five 

 long slender sj)iues on each side before the apex, while the metanotum bears one 

 very small apical spine. The episternnm of the raetathorax bears one or two 

 bristles, and the epime^nm six (2.3.1.). 



Abdomen. — The tergites 1 to 4 have one or two apical sjiines on each side. 

 There are two rows of bristles on tergites 2 to 7, the anterior row not consisting 

 of more than six on segments 4 to 7. The seventh tergite bears one long ai)ical 

 bristle, accompanied on each side by a small hair. Tiie stern ites of segments 

 3 to 7 bear two bristles on each side. In some of the sjieciniens these bristles 

 are accomjiauied by a small hair on the sixth and seventh sternites. 



I^egs. — The hindcoxa does not bear any hairs on the inner surface from the 

 base to the middle, apart from those standing at the anterior edge. There are two 

 bristles posteriorly at the apex of the hindcoxa, the second being much thinner and 

 shorter than the first. There is one short bristle on the outer side of the iiiad- 

 femnr near the base. The hindtibia bears on the outer surface two rows of liristlcs. 

 The longer bristle of the dorsal subapieal pair is as long as the tibia is broad. 

 The tarsal segments have two rows of bristles on the ventral surface, the row 

 standing towards the frontal side of the insect having less bristles than the hinder 

 one. The hindtarsus is very characteristic. One bristle of each of the last three 

 posterior jjairs is very thin and much jirolonged, that of the apical pair reaching to 

 the middle of the fourth segment. One bristle of the apical anterior pair, again, is 

 long and stout, reaching nearly to the apex of the third segment. The longer 

 anterior apical bristle reaches nearly to the apex of the fourth segment, while the 

 corresponding bristle of tlie posterior side reaches to the base of that segment. The 

 first pair of lateral bristles of the fifth segment is distinctly dislocated towards the 

 middle, standing halfway between the second pair and the base. The measurements 

 of the mill- and hindtarsi are as follows : — 



Modified Segments. — cJ. The eiglith tergiti^ is large, ami bears lichiMil the stigma 

 a patch of hairs, ;ind farther back six or seven long bristles. The eighth sternite is 

 very small, being almost concealed in the seventh. The process of the ciaspcr 

 (PI. VIII. fig. 21, r) is short and rounded, bearing three bristles at the apex and two 

 long bristles at the juncture with the finger. The manubrinm (m) is short and 

 broad, being rather abruptly pointed. The finger (k) is broad, being almost oblong, 

 bearing close to the distal edge one stout liristle at the lower corner, a longer one 

 at the upper corner, and between them three short stout sj)ine-like liristles. The 

 ninth sternite (PI. VIII, fig. 21) bears a patch of long thin bristles proximally of 

 the sinus.
