Callieth. zefo'ane.a C. Koch — and registered them together under the 

 denomination of C. scenica, looking on "C. histrionic*" as a separate 

 species. Westring's description shows that he rightly united C. Koch's 

 Callieth. scenica and ldstrionica under his Attus Idstrionicus. Westring's 

 Attiis scmicns Var. a, or A. lineolatus Send., seems on the contrary, 

 as has already been said, to be the same as C.zebraneaC Koch: his 

 A. scenicus Var. b again is probably identical with C. tene.ru C. Koch. 

 Westring has kindly lent me cf and Q ad. of both Var. a and Var. b 

 of his A. neemeiM for examination. "Var. a", which, with Simon and 

 C. Koch, I take to be the same as Ar. cingulata Panz.') and there- 

 fore call Epibl cingulatum, I have myself found not only in Sweden 

 but also at Kissingen in Bavaria: of "Var. b" (Epibl. tenerum n.) I have 

 seen not only Swedish specimens, but specimens from Bavaria and 

 Austria, the former sent me by L. Koch, the latter by v. Kempelen. 



The difference between C. ldstrionica C. Koch and C. scenica id. 

 lies only in the colour, which nevertheless shows evident transitions 

 from the one form to the other. In "C. ldstrionica" the cephalotho- 

 rax has a white spot immediately above the anterior centre eyes 

 and a similar spot behind each of the two hindermost eyes; but the 

 first- mentioned spot is often dilated into a transverse band, which 

 sends out a short white line straight backwards, and the two spots 

 behind the hindermost eyes are often united into a streak angularly 

 bent backwards, or into a patch, which is connected with a white or 

 reddish a on the posterior slant of the cephalothorax, so as to form 

 an H-or X-shaped figure (conf. Westring's description!), and the 

 cephalothorax then has the figuring which distinguishes "C. scenica"; 

 should there be, in addition, small whitish angular marks between 

 the oblique white transverse bands on the abdomen, we have at once 

 the typical "C. scenica" before us, as figured in Die Arachn., fig. 1107, 

 especially if the legs, as in such varieties is frequently the case, are 

 considerably paler than in the form "C. ldstrionica". The colour of 

 the 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 ater 

 dorso macula cruciformi cinerea. Abdomen ovatum nigrum, basi cingulo semi- 

 lunari cinereo, medio duabus interrupts. Pedes nigro- cinereoque variegati." Panz., 

 loc. cit. — The line beside the figure, that indicates the length of the animal, is 

 6 millim. long, wherefore Ar. cingulata cannot well be identical with E. tenerum n., 

 which is far smaller.
