median line unci also slightly ni-arcr the suture. It is often larking or 
very weakly developed. 
Anterior dorsoccnirals: two rows of bristles inserted on tlie inner 
margin of the first lateral pair of vittae (PI. 4, fig. 2o, hdcti.). 
Posterior dorsoccntrah: similarly placerl to the al)ov<' hut hehind 
the transverse suture (PI. 4, fig. 25, hdrp.). 
Anterior acrostirlials: two rows, one in.serted on each side of the 
nieilian vitta (PI. 4, fig. 25, hn.'i.). Their arrangement is never (juite 
symmetrical. 
Posterior acrostichals: similarly placed to the above but behind the 
transverse suture. Usually the last or prescutellar pair is present, 
sometimes all arc absent. 
Supra-ahirs: usually three bristles in.serted on the pre-alar callus 
(PI. 4, fig. 25, bsa.). 
Postalars: two bristles situated on the postalar callus (PI. 4, fig. 25, 
bpa.). 
ScutcUar apicah or Apicals: a pair of bristles inserted at the apex of 
the scutellum; sometimes crossing and usually weaker than those 
next to them laterally (in Villeneuve's genus Blaesoxiphella the apical 
bristles cross and are the longest, see Ann. Mus. Nat. Hung. Budapest, 
1912, vol. 10, p. 613). Generally present in males, absent in females 
(PI. 4, fig. 25). 
Suhnoto pleurals: a short row of bristles on the upper, anterior por- 
tion of the mesopleura, extending more or less diagonally downward 
and backward. 
Mesopleurcd: a row of bristles inserted near and paralleling the 
posterior border of the anepisternum (the large anterior portion of the 
mesopleura) . 
Sternopleieral: bristles situated on the sternopleura just beneath 
the sternopleura] suture; usually three (PI. 3, fig. IS, hspL). 
Lower sternoplcural: a row or several rows of bristles situated on the 
ventral portion of the sternopleura (PI. 3, fig. 18, hstl.). 
Pteropleural: an unimportant group of bristles near the upper 
margin of the pteropleura, just beneath the subalar plates (PI. 3, 
fig. 18, hppl). 
Hypoplexiral: a slightly curved fan-like row of closely set bristles 
on the hypopleura (PI. 3, fig. 18, hhpl.). 
Abdomen. 
Marqinals: bristles inserted on the posterior dorsal margin of any 
segment; two or more (PI. 5, fig. 31, hm.).
