Mr. R. S. Bagnall on new Thysanoptera. 297 



abdominal bristles, those on segments 7 to 9 being nearly as 

 long as the tube. It differs from usitatus (Bagn.) in this 

 latter respect and also in the longer head and prothorax. 



Hob. German East Africa; Aruska, Oct. and Nov., 

 1905 (C. Katona). 



Haplothrips longisetis, sp. n. 



? . — Length about 1*75 mm. 



Elongate and linear. Brown, first abdominal segments 

 somewhat lighter ; tube darker basally ; femora grey-brown \ 

 tibioe yellow, tinged with brown on the outer margin and 

 basally ; third antennal joint yellow, fourth rather lighter 

 brown than the succeeding joints. Wings colourless, trans- 

 parent, posterior margin of fore-wing with four cilia dupli- 

 cated near apex. Head 1*14 as long as broad, about 1*25 

 as long as the prothorax, and about 0*6 the length of the 

 antenna?. Mouth-cone very short and rounded. Prothorax 

 1*6 as broad as long ; all seta3 present, knobbed. Fore-tarsus 

 with prominent tooth. Tube - 58 the length of the head ; 

 apical setae exceptionally long, 2"25 times as long as the 

 tube ; those on ninth abdominal segment 1*5 the length of 

 the tube. 



H. longisetis comes in the aculeatus group, but is readily 

 recognized by the long apical abdominal hairs. 



Hob. Alexandria : one example found in a dead twig of 

 fig {Ficus sp.), March 6th, 1905. 



Submitted by Mr. F. V. Theobald. 



Haplothrips brevicollis, sp. n. 



$ . — This species has the fore-tarsus unarmed and comes 

 nearest to cahirensis (Tryb.). It may be separated from all 

 the species in that group, however, by its very short and 

 strongly transverse prothorax. The head is nearly 0*9 as 

 broad as long and 1*85 times the length of the prothorax, 

 which latter is 2*3 times as broad as long. The tube is 0*6 

 the length of the head. The posterior margin of the fore- 

 wing has six cilia duplicated near the posterior margin. 

 Hob. AFRICA: Kibosho, 1903 (Kittenberger). 



Iloplandrotlirips hoodi, sp. n.* 



Forma macroptera. — Length 1*2 to 1*5 mm. 



Colour yellowish-brown to grey-brown ; tube grey-brown, 



* Named in honour of the American Thvsanopterist, Mr. Douglas 

 Hood.
