62 [March, 



head ; relative leng-ths of joints 8 : 14 : 14 : 16 : 14 : 12 : 14 : 8.5 ; second joint 

 constricted at base and truncate at apex, three-fifths as broad as long ; third 

 obconical, foi;rth and fifth broadly claviform, sixth oviform and constricted 

 near base, seventh elongated, more than twice as long as broad and truncate at 

 apex, the apical joint narrowed to tip ; joints 2 — 4 equally broad and 6 and 7 

 two-thirds as broad as either of them. A pair of light-coloiired and indistinct 

 sense-cones on each of the segments 3 — 6. 



Prothorax three-quarters the length of head, and one and two-fifths as 

 broad across hind angles as long, or one and three-quarters as wide across fore- 

 coxas as long ; fore-margin narrowly emarginate, hind margin arcuate Bristles 

 at posterior and anterior angles and the mid-lateral pair present, erect and 

 knobbed, others apparently obsolete ; the j^air at posterior angles the longest, 

 being about one-third as long as the prothorax and half as long again as the 

 fore-coxal spine, which is similarly knobbed. Pterothorax about as broad as 

 the prothorax, narrower than width across the fore-coxJE, longer than broad, 

 the metathorax being exceptionally long. Wings reaching to about the fifth 

 abdominal segment, fore-wing apparently constricted near middle, cilia long 

 and widely separated ; median vein absent. Legs stout, fore-fem\ar long and 

 less than one-half as broad as long ; all the tarsi dark brown on the chitinous 

 part of the second segment on the inner side ; fore-tarsal tooth apparently 

 absent. Two exceptionally long and slender bristles at apical third of inter- 

 mediate tibiffi and a similar bristle on hind tibia, which has a short spine at 

 apex without. 



Abdomen occiipying two-thirds the total length of the insect ; very gently 

 and slightly widened to fifth segment and narrowing from seventh to base of 

 tube. Tube slightly more than one-half as long as head, twice as long as 

 broad at base and one-half as wide at tip as at base ; terminal bristles excep- 

 tionally long, tapering and coloiu-less towards tips, almost twice as long as the 

 tube ; those at apex of ninth abdominal segment similar to, and as long as, the 

 terminal ones. Bristles on eighth segment knobbed, lateral bristle of seventh 

 segment rather long and tapering, and apparently not knobbed, all other abdo- 

 minal hairs shorter', straight and knobbed. 



Habitat : Denmark, a siiig-le example taken on a cruciferous 

 flower in tlie Palm House of the Botanical Gardens, Copenhagen, 

 June 30th, 1909. 



Phlceotheips brevicollis, sp. nov. 



? . Length, 2'5 mm. ; breadth of mesothorax 048 mm. 



Like Phloeothrips coriaceus ; diifering in having the third antennal joint 

 much shorter, subequal in length to the fovu-tli and having the distal half 

 shaded with brown, Avhilst all the antennal joints are relatively shorter and 

 broader. 



The head is one-fifth longer than broad and has the cheeks set with fewer 

 and much more minute spine-set warts, whilst the surface of the head is less 

 strongly coriaceous, and the fore-femora are almost smooth. The mouth-cone 

 is rather pointed and reaches to the base of the presternum. 



The fore-tibia is shaded with brown, darkest at the outer edge, and is clear
