same reason, I presume, he makes no reference to strnctural differences 

 in most of the forms referred to. Horvath's view, like that of the 

 late Mr. E. Saunders, to whom I showed the insect last year, is that 

 the structural distinctions in the present insect, and the difference in 

 habitat, are sufficient groiuids for its specific separation, and with this 

 view I cei'tainly concur. 



It is not necessary to do more than point out whei'eiu P. j)rt7?<sfr/s 

 differs from the allied species. The (^ is smaller than in P. nmfasciahis, 

 and the fore parts are duller, because more rugose. The pronotuni 

 has no yellow margin, bvit is wholly black ; the scutellum has only the 

 extreme apex yellow ; the clavus is black and the corium has only a 

 humeral streak, its apex next the cuneus, and a niinute streak at the 

 inner angle just beyond the claval suture, yellow ; the cuneus is black, 

 passing into red and then yellow at each end. The antennae are darker, 

 and have the terminal joint longer than the third, considerably longer 

 than in P. nnifasciatus. The femora are chiefly black. The ? 

 resembles the (^ in coloration, rugosity, and stritcture of antennae, 

 but is slightly broader than in P. anifasciatus, and with more rounded 

 sides. Length, 4^ — 5 mm. 



Thus the difference in size, the greater rugosity, the length of the 

 terminal joint of the antennae, the general melanic coloration, and the 

 habitat, easily distinguish the insect. 



I found one (^ and one ? amongst rushes in a wet field just 

 outside the town of Carmarthen, and one 2 at roots of rushes at 

 Eookiey Wilderness, Isle of Wight. At Pendine, I obtained seven 

 $ $ and one (^ , all of them by searching at roots, and I cotdd get 

 none by sweeping, as they were too low down amongst the rushes. 

 In fact, the only specimen I have taken at all by sweeping is the 

 above-mentioned ^ from the wet field at Carmarthen. On the Con- 

 tinent it is found on Galium. jKilustre, while P. unifasciatus occurs 

 chiefly on G. vermn, and not at all on G. i)alustre. I did not notice 

 any Galium in any of the above localities, though other plants were, 

 ill some cases, growing wdth the rushes. But the insects when found 

 were certainly crawling on the rushes. All my specimens were taken 

 in August and September. The insect occurs also in South Finland 

 (Renter), Germany (Scliwmaclier), Hungary and Japan (HorvathJ.
