base of head, and set with a few extremely minute spines. Eyes 

 moderate, finely faceted. Ocelli large and well separated ; posterior 

 ocelli contiguous with margins of eyes ; front ocellus placed at 

 extreme vertex. Post-ocular bristles small. Mouth-cone decidedly 

 shorter than its breadth at base ; blunt at tip, and not reaching half- 

 way across prosternum. Antennae narrowly separated at base, not 

 quite twice the length of head ; joints comparatively short and 

 stout; fourth joint thickest. 



Colour brownish black ; third joint lighter ; spines and sense-cones 

 short and inconspicuous. 



Prothorax twice as broad (across the outer angles of the fore- 

 coxae) as long, with a long spine at each posterior angle. Meso- 

 thorax wider than the prothorax ; sides of metathorax gently 

 curved and very gradually narrowed to base of abdomen. Legs 

 comparatively short, fore femora slightly thickened, and each fore- 

 tarsus armed with a minute tooth ; all tibiae and tarsi brownish 

 black. Wings always present. 



Abdomen a little more than twice the breadth of head, from two 

 and one-half to three times as long as wide ; sides tapering gradually 

 and evenly to base of tube from the fourth segment. Tube about 

 two-thirds the length of the head, sides straight and only tapering 

 slightly to apex. Terminal spines — namely, those on the eleventh 

 abdominal segment — only one-half the length of tube. Abdominal 

 spines long and slender. 



$ . Similar to the female, but in general form smaller and more 

 slender. Antennae comparatively longer and more slender ; fore- 

 legs thickened and foretarsal tooth prominent. At each hind angle 

 of the ninth abdominal segment there is a short, stout, and acute 

 spine. 



Hah. Numerous specimens from the flowers of Europs, Diplo- 

 pappus, Olipterus, and Sehcea ; Cape Town. 



Dr. L. P^ringuey has kindly communicated a single carded 

 specimen of Thysanoptera for examination. It belongs to the 

 genus Panurothrips, Bagnall, recently erected for the reception of 

 P. gracilis, Bagnall, from Siam, and, on account of the exceptionally 

 long tube, may be called P. caudatus.
