NEW GENERA AND SPECIES OF THYSANOPTERA 1 85 



Order THYSANOPTERA (Physapoda) 



Sub-Order TEREBRANTIA Haliday 



Family THRIPID^ Haliday 



Genus APTEROTHRIPS* nov. 



Head wider than long. Eyes slightly protruding. Ocelli 

 absent. Alaxillary palpi three-segmented. Autennce eight- 

 segmented, with the two-jointed style shorter than the sixth 

 joint. 



Prothorax as long as or a little longer than head, one short 

 spine at each posterior angle with two subsidiary spines above 

 same. Wings absent. Legs stout. Abdominal spines weak, 

 no prominent spines at hind angles of intermediate segments. 

 Anal spines comparatively long, slender. 



TyTpQ—Aplerolhrips snbreticulata mihi. 



Easily recognised from the examples of the geniis Enthrips 

 Targioni-Tozzetti, by the absence of the two long spines at 

 posterior angles of the prothorax, and also by the total 

 absence of both ocelli and wings. 



The genus is perhaps more closely allied to Pachythrips 

 Uzel (type P. subaptera Hal.), but differs in the form of head, 

 arrangement and modification of anal spines, and the entire 

 absence of wings. 



Apterothrips subreticulata sp. n. (PI. VL, figs. 1-3). 



Length 1.3 mm. , breadth of mesothorax '2 mm. 



Colour dark brown, legs and antennae lighter. 



Head only slightly broader than long, frontal margin 

 broadly and evenly rounded ; hind surface irregularly wrinkled, 

 forming a semi-reticulate sculpture at base of cheeks, which are 

 widened below eyes ; a series of minute spines across head 

 immediately behind eyes, and still more minute spines between 

 them. 'Eyes small, bulging slightly, very coarsely faceted, 

 * Aptero- = wingless.
