228 [October, 



Abdomen lonjj, not, or only very slightly, broader than pterothorax. 

 Tube 0-9 the length of tlie prothorax, and 0-6 the length of the head. Apical 

 bristles long and slendcsr, as long as tube and almost colourless, except near 

 tube where they are greyisli. In H. aculeatus the apical bristles are wholly 

 greyish-brown. 



[The following table will help to show the distinguishing characters 

 of the two species at a glance : — 



Wings clear. Tube 0(5 the length of the head and only a little more than 

 twice as long as broad at base : 



1. Size smaller (length, Ti — 1'6 mm.). Head only slightly longer 



than broad; antennae more than 1'5 times as long as the head. 

 Fore-wings with 5 — 6 duplicated bristles... H. aculeatus (Pabr.). 



2. Size larger (length, 2-1— 2-35 mm.). Head 1'35 times as long as 



broad ; antenna3 only 1'35 times as long as the head. Fore- 

 wings with 9 — 12 duplicated bristles H. juncorum, sp. n.] 



The larva is red, with the head and antenna', the protlioracic plates, the 

 legs, the basal half of the 8th alidominal segment and segments 9 and 10 gi'ey- 

 brown, though not conspicxxously so.

Haplothrips distinguendus (Uzel).

This species comes near to H. statices, and is sharply distinguished by 

 having the 3rd antennal joint and the basal third of joints 4, 5, and 6 yellow. 



The head is shorter, I'l times as long as broad, the wings are clear, and 

 the tube aboiit 0'75 the length of the head. In my specimen the 1st antennal 

 joint is grey, and lighter tlian the second, wliilst the tube is distinctly darker 

 than the rest of the body, and the fore-tibia; are yellow broadly shaded with 

 grey at inner and outer margins. The hind margin of the fore-wing has 14 

 duplicated cilia near apex. My specimen is 2'2 mm. long, i.e., distmctly larger 

 than Uzel's type. 



Hah. : Weston-on-the-Green (Oxon.), one example (?) by beating 

 sedge-stacks, August, 1913. 



The minor differences noted above make it inadvisable to refer 

 the species to H. distinguendus with certainty. A series of specimens 

 would enable one to settle the point, and I am hopeful of meeting with 

 it again. Sedge is evidently not its true pabulum.
