similar h.airs. The metanotnm has fonr irregular rows of short stout bristles, besides 

 additional dorsal hairs and a postmedian row of long bristles. There is a comb of 

 seven short apical spines on the two sides together. The large metathoracic 

 ppisternnm bears dorsally a long bristle witli a short hair below it, and anteriorly a 

 vertical row of four to six more, and a ventral, nearly horizontal, row of three 

 beside. There is one bristle on the sternnm. The epimernm, which is very much 

 higher than it is wide, bears a row of seven bristles anteriorly, another row of four 

 from the stigma downwards, and two bristles in between the rows, besides two small 

 hairs, one of which is placed above and one beneath the uppermost bristles of 

 the second row. 



Abdomen. — The tergites 1 to 7 bear two rows ^of bristles, the first and 

 second tergites possessing in addition a short third row ; this third row being 

 represented by two or three bristles also on the third and fourth segments. Both 

 rows of bristles extend down beyond the stigmata, except on the seventh segment. 

 The number of apical spines on the tergites are on the two sides together : 7. it. 11. 

 9. 6. 4. 2. The basal sternite bears on each side abont twenty hairs and at the 

 ventral edge a long bristle and more proximally several finer ones. The following 

 four sternites bear a row of six long bristles and in front of them four to six shorter 

 ones. The sternite of the seventh segment has a row of seven or eight bristles and 

 six to eight hairs before this row. 



Iieg^s. — The mid- and hindcoxae bear posteriorly at the apex fonr or five 

 bristles. The hindfemur has ventrally on the outer side a row of five long bristles 

 from tlie apex forward, the row being continued anteriorly by two shorter bristles, 

 which are preceded by two more bristles standing a little separate from the ventral 

 edge. On the outer surface the hindfemur bears an irregular row of seven or eight 

 bristles and a subdorsal row of four or five. The bristles on the outer side of the 

 midfemnr are a little less numerous. The mid- and hindtibiae have nine dorsal 

 incisions. The sixth and apical incisions bear the longest bristles. The longest 

 apical bristle of the midtibia reaches nearly to the middle of the second tarsal 

 segment, wliile that bristle of the hindtibia extends to the ape.x of the first 

 segment. There is one row of seven bristles on the inner side of the hindtibia and 

 two and a half rows of bristles on the outer side, besides numerous hairs situated 

 at and near the anterior edge. The first foretarsal segment is two-thirds the length 

 of the second. The first and second segments of the midtarsus are almost equal in 

 length, while the first hindtarsal segment is very much longer than the second 

 The apical and snbapical bristles of the hindtarsus are stout and rather short, the 

 longest apical liristle of the first segment not reaching to the apex of the second. 

 The measuv ments of the mid- and hindtarsi are as follows : — 



Modified Segments. — The seventh sternite (PI. XIV. fig. 12, vii. st.) is obliquely 

 sinuate, the lobe above the sinus being rounded and^the lobe below the sinus being 

 slightly bi-emarginate. The eighth tergite is comjiletely divided dorsally in the 

 mesial line. It bears very numerous short hairs at the edge and on the lateral 

 surface (PL XIV. fig. 12).
