Anthothrips Uzel. 



(i) Anthothrips nsitatits, sp. nov. 



Plate XVII. figs. II — 14. 



%. Length rg mm., breadth of mesothorax o'285 mm. 



Colour uniform dark brown, all tarsi yellowish and fore-tibia shaded to yellowish- 

 brown at tip ; antenna! joints three to five yellow, sixth tinted with brown and the 

 apical and penultimate joints light brown. 



Head about one and one-quarter as long as wide through eyes, and one and three- 

 fifths the length of the prothorax, widest behind eyes with the cheeks slightly 

 rounded and narrowed posteriorly. Eyes prominent, occupying laterally about three- 

 eighths the dorsal length of head ; obtusely rounded and composed of somewhat 

 large facets, pigment deep shading from a rich crimson to a deep black ; post-ocular 

 bristles knobbed, short and slender, about as long as the eye. Ocelli large, the anterior 

 one being placed at the extreme vertex of the head which is slightly raised in the form 

 of a hump between the eyes ; and the posterior pair placed above a line through centre 

 of eyes, and touching their inner margins. Mouth-cone blunt at tip and only reaching 

 a little more than half-way across the presternum ; maxillary palpus long and broad 

 with the apical joint more than three times the length of the basal joint and furnished 

 with several sense-bristles at tip. Antennae about one and one-half times as long as 

 the head, sub-approximate at base, joints three to six somewhat broadly claviform, 

 practically sub-equal, the fourth being the broadest, and the sixth decidedly shorter and 

 narrower than either of the three preceding joints. Sense-cones slender, long and 

 acute, two on each of the joints three to six ; spines slender, rather short and light 

 coloured and therefore inconspicuous. 



Prothorax about five-eighths as long as broad, slightly widened to mid-lateral 

 angles ; anterior margin emarginate, all bristles present, slender and knobbed, those at 

 each posterior angle longest, those at each anterior angle and posterior-marginal pair 

 long and about sub-equal ; anterior-marginal and mid-lateral pairs shorter again and also 

 sub-equal. Surface of prosternum deeply reticulated. 



Pterothorax broader than the breadth across fore-coxae, about one and one-quarter 

 times as long as broad ; sides of mesothorax sub-parallel, and the metathorax rounded 

 laterally to base of abdomen. Wings present, long and slender, reaching to the sixth 

 abdominal segment, apparently slightly narrowed near middle ; median vein obsolete ; 

 posterior fringe near apex double for eight or nine hairs. Legs long, the fore-leg 

 slightly incrassate, fore-coxa with one prominent bristle and fore-tarsus armed with 

 a minute tooth. 



Abdomen about two-thirds the total length of the insect, and about as wide as the 

 pterothorax ; sides sub-parallel to the eighth segment and from thence narrowed to the 

 tube.
