Mr. R. 8. Bagnall on new Thysanoptera. 357 
with light brown and 8 wholly of a light grey-brown. 
Wings clear. 
Head with cheeks parallel to near neck and then some- 
what constricted ; 1°6 times as long as broad and about 1°6 
times as long as the tube. Mouth-cone evenly pointed. 
Postocular bristles colourless, knobbed, very short, not 0°5 
the length of an eye, and situated exceptionally far back, 
nearly halfway between the hind-margins of eyes and the 
neck. Antenne with joint 3 very slender and elongated ; 
relative lengths of jomts 3 to 8 approximately as follows :— 
72 305.2507 46.: 36; > 16: 
Pronotum transverse, less than 0:5 the length of the 
head ; sete developed, colourless, knobbed ; only the postero- 
marginal long, the outer being about 0°6 the median 
pronotal length. Wings, reaching abdominal segment 6, 
with a series of 15-18 duplicated cilia. Fore-tarsus 
unarmed. 
Abdomen roundly narrowing from segment 7 ; tube 0°6 
the length of the head; abdominal bristles colourless, 
knobbed ; longest on 9 about 0°8 the length of the tube. 
2? —Length about 2°4—2°7 mm. 
Larger and heavier. I have no perfect examples of the 
sex, and have therefore described the species from the ¢. 
Two species have asimilar-coloured antenna—ZL. tarsidens, 
Tryb., from Madagascar, and L. major, Buffa. The former is 
at once separated by the armed fore-tarsi, relative lengths of 
antennal joints, the long tube, etc. The latter remains to 
be described, but if it so closely approximates se¢inodis as 
Buffa states, it may be known by the relative lengths of 
antennal joints 3 to 8, the short broad head, the compara- 
tively longer tube, ete. 
Type. In Coll. Bagnall. 
Hab. BE. Arrica, Mongalla Prov., January 1911 (4. ZH. 
King). 
Liothrips damfi, Karny. 
This species comes near to L. micrurus, Bagn., but is at 
once distinguishable by the shape of the head (the vertex of 
which in micrurus is produced in the form of a hump), the 
longer tube, the more minute postocellar sete, and the 
longer and stouter pronotal sete. 
Hab, Sprain, S. Esteban, 23. vi. 1912 (Navas), both sexes.
