have called E. agalena Walck. The female of this South-European 

 species, which I, with Dr L. Koch, take to he E. dalmatica Doleschall ') 

 and which appears to be but little known, is about 7 millim. long, 

 its cephalothorax 3, the list pair of legs 11 millim.; the abdomen 

 is 4 3 / 4 millim. long and nearly as much in breadth. It is therefore 

 not inconsiderably larger than E. agalena (C. Koch), cet. The area 

 af the centre eyes is rectangular or a trifle broader before than be- 

 hind. The posterior centre eyes are considerably larger than the 

 anterior, and the anterior lateral eyes, which make with the anterior 

 centre eyes a line almost straight, scarcely perceptibly curving back- 

 wards , are separated from the anterior centre eyes by an interval 

 double as great as that between the two anterior centre eyes. The 

 cephalothorax is brownish yellow, mottled more or less distinctly with 

 dark brown on the pars cephalica, and has sometimes dark radi- 

 ating lines on the pars thoracica. The legs are brownish yellow, 

 the thighs at the apex blackish brown, the remaining joints have 

 brown rings. The sternum is dark brown; along the middle it has 

 a large, oblong, yellow spot narrowing behind. The abdomen, which 

 is broad and short, triangular with the corners rounded off, without 

 projecting humeral protuberances, is brownish yellow above; in the 

 extreme front it exhibits a triangular spot enclosed in paler lines, 

 which is continued backwards as a more or less distinct, lanceolate 

 middle area along the back; in the midst of the back are 4 black 

 points, so disposed as to form a trapezium, and towards the sides, from 

 the middle to the anus, two undulating blackish lines extend, which 

 converge towards the anus, forming in front a very open, almost 

 right angle with each other. The midst of the belly behind the 

 rima genitalis is occupied by a black transversal area, which is 

 bounded by 4 large yellow spots: the two spots that are on the same 

 side are on their outer side united by a narrower yellow longitu- 

 dinal stripe, thus together forming a (- or [-shaped band; within 

 the black area bounded by these two bands, may sometimes be seen 

 two small yellow points, and immediately behind the hindermost of 

 the above mentioned four spots two other large yellow spots close 

 before and beside the mamillse: at the sides of these, more back- 

 ward , two smaller yellow spots' may in general be found. The vulva 

 is drawn out into a scapus, which is usually about double as long
