190 NEW GENERA AND SPECIES OF THYSANOPTERA 



but remote from their margins. Post-ocular and dorsal spines 

 long. Aniennce^ broken in the type, basal joints not approxi- 

 mate. JWouf/i-cone va.ther long and slender, and ending bluntly; 

 second joint of maxillary palpus long and rather stout, four 

 times the length of basal joint. 



Prothorax widening gradually to base, only slightly raised 

 to the posterior edge, near which there is a strong transverse 

 impression or channel. Anterior-marginal spines obsolete, 

 posterior-marginal, mid-lateral and spines at angles present. 

 Anterior coxa large with one conspicuous spine; femur swollen 

 and armed with a series of acute teeth at the anterior half of 

 the inner edge. The first and longest tooth is situated at 

 about the mid-line, and is followed apically by three smaller 

 teeth each less than the one preceding in size, the fourth tooth 

 being followed by a minutely serrate edge. The fore-tibia is 

 comparatively long, slightly swollen opposite the principal 

 tooth, and roughened in such a way as to suggest a 

 stridulating surface. Above the main fore-tarsal tooth there 

 is a second and slenderer spur, this important character 

 suggesting the specific name hmncinata. Pterothorax broader 

 than the width across the fore-coxae, and broader than long. 

 Posterior and intermediate legs long and slender, sparsely 

 covered with slender spines. Wings coriaceous, reaching to 

 seventh abdominal segment. 



Abdomen long, about three-quarters the length of the whole 

 insect ; narrowing gradually from the sixth segment to tube. 

 Tube long (07 mm.), and nearly three times as wide at base 

 (o'2 mm.) as at apex (0*072 mm.). Terminal hairs com- 

 paratively long, and abdominal spines stout. 



Type — One male in the Amsterdam Museum. 



Hab. — South New Guinea (Netherlands' New Guinea 

 Expedition, 1904-5). 



Genus DINOTHRIPS* nov. 



Head not quite twice as long as broad, and slightly longer 

 than the prothorax ; cheeks set with several strong spines. 

 * Dino- =terrible.
