Tceniothrips major, sp. x\. 



$ . — Lenojth about 2*0 mm. 



Colour dark chestnut-brown ; fore-tibiae, hind-tibige basally, 

 all tarsi, and third antennal joint not quite so dark. Fore- 

 wings brown, slightly lighter distallj. 



General form as in T. inconsequetis (Uz.). 



Head almost as long as broad ; eyes bulging, coarsely 

 facetted, pilose ; cheeks swelling out from behind eyes as in 

 T. primulce and inconsequens. A series of dorsal and lateral 

 setse on a line behind eyes. Ocelli large ; a pair of very long 

 and strong inter-ocellar bristles situated between the posterior 

 ocelli ; a shorter pair on vertex close to inner margins of 

 eyes and beyond the anterior ocellus, which is directed 

 forwards. Dorsal surface transversely striate in basal half 

 or thereabouts. Antennae long and slender, about 2'3 times 

 the length of head ; joints 3 and 4 fusiform ; relative lengths 

 of joints:— 16 : 22 : 40 (with stem) : 36 : 25 : 32 : 4 : 5 ; 

 forked trichomes on 3 and 4 long and slender. 



Prothorax transverse, not quite as long as the head ; 

 broadest at posterior angles ; bristles at posterior angles long 

 and slender; a line demarcating posterior margin ; a pair of 

 longish mid-dorso-lateral setae, and several short setse, curved 

 and chiefly lateral. Pterothorax large. Wings long, strong, 

 pointed at apex, reaching to ninth abdominal segment ; sette 

 slender. Fore-wings with three or four seta3 on distal half 

 of upper vein, namely, one just within the distal half and 

 l-fO + l or 1 + 1 + 1 in the distal fifth or thereabouts. 



Abdomen elongate, pointed at apex from base of segment 8 ; 

 apical bristles long, especially those on 9, which is also 

 furnished with a pair of shorter dorsal bristles. 



This is a true Tceniothrips, coming nearest inconsequens 

 (pt/ri), from which it differs chiefly in the much larger size 

 and darker coloration, the chaetotaxy, and in the slender 

 antennae.
