Callieth. zelranea C. Koch — and registered them together under thedenomination of C. scenica , looking on ”C. Idstrionica' as a separatespecies. Westring’s description shows that he rightly united C. Koch'sCallieth. scenica and Idstrionica under his Attus histrio?dcus. Westring’sAitus scenicus Var. a, or A. line.olatus Sund., seems on the contrary,as has already been said, to be the same as C. zebranea C Koch: hisA. scenicus Var. h again is probably identical with C.tenera C. Koch.Westring has kindly lent me cf and Q ad. of both Var. a and Var. bof his A. scenicus for examination. ”Var. which, with Simon andC. Koch, I take to be the same as Ar. cingulata Panz. ’) and there-fore call Epibl cingnlatum, I have myself found not only in Sweden but also at Kissingen in Bavaria : of "Var. b" (Epibl. tenerum n .) I haveseen not only Swedish specimens, but specimens from Bavaria andAustria , the former sent me by L. Kocn, the latter by v. Kempelen.

The difference between C. Idstrionica C. Koch and C. scenica id.lies only in the colour , which nevertheless shows evident transitionsfrom the one form to the other. In ”C. Idstrionica” the cephalotho-rax has a white spot immediately above the anterior centre eyesand a similar spot behind each of the two hindermost eyes; but thefirst-mentioned spot is often dilated into a transverse band, whichsends out a short white line straight backwards, and the two spotsbehind the hindermost eyes are often united into a streak angularlybent backwards, or into a patch, which is connected with a white orreddish a on the posterior slant of the cephalothorax, so as to forman H-or X-shaped figure (conf. Westring’s description!), and thecephalothorax then has the figuring which distinguishes ”C. scenica']should there be, in addition, small whitish angular marks betweenthe oblique white transverse bands on the abdomen, we have at oncethe typical ”C. scenica” before us, as figured in Die Araclin., fig. 1107,especially if the legs, as in such varieties is frequently the case, areconsiderably paler than in the form ”C. Idstrionica”. The colour ofthe upper part of the abdomen in Koch’s figure of ”C. scenica cf” (fig-1106), also appears to me to show that this spider is but a variety

1) ”Aranea cingulata cinerea, abdomine ovato nigro cingulis tribus cinereis,secunda tertia interrupta. Habitat in arboribus coniferis. Thorax depressus aterdorso macula cruciformi cinerea. Abdomen ovatum nigrum, basi cingulo semi-lunari cinereo, medio duabus interruptis. Pedes nigro- cinereoque variegati.” Panz.,loc. cit. — The line beside the figure, that indicates the length of the animal, is6 millim. long, wherefore Ar. cingulata cannot well be identical with E. tenerum N.,which is far smaller.
