Genus BRacHYUROTHRIPS, NOV. 
Near Panchetothrips, Bagnall. Head short and trans- 
verse, without thickened collar. Eyes prominent, protruding. 
Antenne .... Mouth-cone reaching across prosternum, 
maxillary palpi. ... Prothorax strongly transverse, with- 
out prominent bristles. 
Pterothorax large. Wings long, rather pointed, both 
pairs minutely setose : costal spines on fore-wing excep- 
tionally long; veins obsolete, with a few setz on a line 
corresponding to the fore-vein near to costa. 
Abdomen broadly ovate as in Panchetothrips ; pleurites 
overlapping. The ninth segment cylindrical, longer than 
broad; tenth very short, broader than long; ventral opening 
rather close ; abdominal bristles long. Ovipositor apparently 
normal. 
Type. Brachyurothrips anomalus, mili. 
Whilst apparently related to Panchetothrips in its 
general form, the overlapping abdominal pleurites, etc., in 
the puzzling nature of its ninth and tenth abdominal seg- 
ments, Brachyurothrips is unlike anything described. I at 
first tried to reconcile the segment described as the ninth with 
the tenth, regarding the ultimate as a highly developed type of 
the vestigial eleventh segment, but without success. There- 
fore Brachyurothrips is chiefly peculiar in the enlarged ninth 
and the short weak tenth abdominal segment. 
Unfortunately there is only one poorly preserved example 
at my disposal.
