Species 10. — Pediopsis tibialis, sp. n. 



(^ and ? dirty yellow; tibice — all the pairs with two short, black, 

 half rings on the inside, placed one near the base, the other 

 before the apex. 



Mead' : face, at the base, with a black (n -shaped character, within which it is more 

 or less punctured with dark brown or black, frequently the sides of the oval at 

 the top and bottom, where it joins the central line, are interrupted ; exterior 

 to the ocelli is a small black spot, below which, and a little more interior, are 

 two somewhat comma-shaped black spots or sometimes unidentate streaks, 

 extending almost to the outer margin a little below the eyes. Lores, next the 

 clypeus, with a small black spot near the apex. AntenncB yellow ; setae brown. 



Thorax : pronotum somewhat coarsely crenulated, the interstices more or less 

 thickly dark brown or black punctured, the punctures slightly elongate ; from 

 behind each eye to the posterior angle is a broad, curved, black streak, its inner 

 margin more or less shaded off into the general colour of the disc ; lateral 

 margins broadly clear yellow ; near the basal angles a small black spot. 

 Scutellum yellow, basal angles with a black triangular spot ; down the centre, 

 as far as the black transverse channel, is a more or less distinct black line, and 

 a little below and within the apex of the triangular spots, a small round or 

 lunate black puncture. Elytra pale yellowish, with a slight brown tinge ; 

 nerves dark brown or black. Clavus — inner margin black, suture very nar- 

 rowly brownish. Membrane — appendix, except a small portion next the clavus, 

 black. Stermim yellow ; pro- and mesosternum, on the sides, with a broad 

 black band. Legs yellow ; coxcb of all the pairs with a black spot in front ; 

 thiyhs — 1st and 2nd pairs brown, apex yellow ; 3rd, at the apex, more or less 

 brown on the sides and top margin. Tibice yellow ; at the base, exteriorly, a 

 short black streak, frequently indistinct or wanting in the 1st and 2nd pairs ; 

 on the inside, a little before the base and also before the apex, is a small black 

 half ring, largest and most conspicuous on the 3rd pair. Tarsi yellow ; apex 

 of the 3rd joint narrowly, and claws black. 



Abdomen above and beneath black, posterior margin of the segments narrowly 

 yellow, or beneath (sometimes) 1st and 2nd segments yellow, except on the 

 sides ; last genital segment black, with an almost round yellow spot on the 

 sides next the apex ; external processes very pale brown, clothed with long, 

 fine, white hairs. Length, (? , If ; ? , 2j lines. 



In appearance, very like P. scutellatus, from which it may be 

 easily separated by the difference in the frons, and also the characters 

 on the tibijB. 



A few examples have been taken by Mr. Douglas and myself at 

 Dartford Heath, also in Headley Lane and in Bexley Road. It 

 occurs on poplai's in July and August.
