1912.) R.S. BaGNnaLL: A new genus of Indian Thrips. 259 
ocellus forwardly directed, placed in centre of forehead on a line 
drawn through the anterior fifth of eyes; posterior pair on a line 
drawn through the posterior third of eyes, the space separating 
them being as great as that between each ocellus and eye. Mouth- 
cone reaching across prosternum. Maxillary paipi three-jointed, 
long and slender. Antenne widely separated at base, more than 
three times as long as the head; first joint short, cylindrical and 
narrower than the second; second widest at middle where it is 
about as broad as long, slightly narrowed distally and truncate at 
apex; third and fourth extremely slender, almost spindle-formed ; 
fifth slightly stouter and broadly jointed to the sixth which is 
roundly narrowed apically ; seventh styliform, parallel sided, and 
eighth continued in the form of a bristle. Relative lengths of 
igints-—G, 12-24, 195, 17, 10, 5, 15. -In’ one specimen the 
fourth joint is only very little shorter than the preceding. 
Prothorax strongly transverse, without any conspicuous 
spines; surface finely and irregularly striated transversely. Ptero- 
thorax large: mesothorax roundly widened to juncture with the 
metathorax which has the sides roundly narrowed to the base of 
abdomen. Both meso- and metathorax laterally convex and with 
the surface reticulated. Surface of all the legs similarly reticu- 
lated; hind pair much longer than the others. Tibia of each hind 
leg furnished with a series of minute bristles for practically the 
whole length of the inner margin. Wings strong and reaching to 
the last abdominal segment; fore-wing narrowing rather unevenly 
from the basal fourth; basal part with a series of four long strong 
bristles on the fore-margin, the third being the longest, and a series 
of ten very long and strong spines on the costa, the last of which 
is the shortest. There are three spines on the basal part of the 
fore-vein; this vein appears to be carried to the extreme tip in 
the form of a thickened fore-margin, and is furnished in the apical 
half with six spines. ‘There is one short and one long spine just 
under the first costal spine, but there appears to be no trace what- 
ever of a hind-vein nor of any spines set on a line corresponding 
with such a vein. ‘The fore-fringe is poorly developed whilst the 
cilia of the hind-fringe are closely spaced, long and slightly wavy. 
The hind-wing has the median vein well-developed, and the hairs 
of the fore-fringe are much shorter and more widely spaced than 
those on the hind margin. 
The abdomen is strongly depressed and margined laterally ; 
and excluding the last segment is broadly oval, in some specimens 
circular. ‘Towards the apex the posterior angles of the segments 
are produced into overlapping spinous processes. The last segment 
is very large and elongated in the form of a tube, bearing at its 
apex four long and two shorter spines, all of which are exception- 
ally stout. ‘The apex of the ninth segment is furnished with a 
series of long, stout spines, the longest over-reaching the tip of 
the last segment; the eighth is furnished at its posterior margin 
with similar but short spines. Ovipositor very long and slender, 
almost straight.
