NEW GENERA AND SPECIES OF THYSANOPTERA 215 



five claviform ; six to eight fusiform. Basal joints short ; third 

 joint nearly six times the length of second ; fourth and fifth 

 subequal, together as long as the third ; sixth and seventh 

 subequal, and together very slightly longer than the fifth; 

 apical joint one-half the length of the penultimate ; spines and 

 sense-cones inconspicuous. 



Prothorax one-half the length of head, and about one- 

 quarter broader than long, irregularly foveolate, a very deep 

 transverse depression before base, and with irregular and 

 somewhat shallow fovea on each side of central channel, 

 which is most distinct apically. Strong spine-set tubercle at 

 each posterior angle. The fore-coxa is armed with one very 

 long spine and a few subsidiary spines. The fore-femora are 

 slightly swollen, and have each a few long spines on the 

 outer edge and several shorter ones, as well as a regular 

 series near the inner edge. The fore-tarsal tooth is very 

 minute. Ptcrotliorax nearly half as broad again as the pro- 

 thorax, and two and a half times the width of head. Meta- 

 sternum laterally rounded and narrowed to base. Intermediate 

 and posterior legs long and slender. Wings reaching to sixth 

 abdominal segment ; cilia not heavy. Tube long and slender, 

 slightly longer than the head, and at least three times the 

 length of the ninth abdominal segment; terminal hairs short 

 and weak. Bristles at apex of ninth abdominal segment about 

 three-quarters the length of tube. Abdorhinal spines com- 

 paratively long. 



$. The male is slightly smaller than the female, and has the 

 fore-femora slightly more swollen ; the fore-tibi?e broader, and 

 the fore-tarsus armed with a strong broad tooth. The 

 abdomen is slenderer, whilst the tube is very slender. The 

 ninth abdominal segment is shorter, and the tube, though 

 only the length of the head, is six times the length of the 

 ninth abdominal segment. 



Type — In coll. Godman and Salvin.
