The pars cephalica is in the fore part, and immediately behind the 

 white crossband above the anterior row of eyes, covered with red- 

 dish scales having a metallic lustre (which seems not to be the case in 

 E. scenicum), and has on the hind part a large, almost X-formed patch 

 or area. In uninjured specimens a short white transverse line al- 

 ways appears before, and a similar one behind, each of the two hin- 

 dermost eyes, which lines extend downwards towards the broad white 

 marginal band. The colour of the abdomen in the female, on the 

 back, is either, as in C. Koca's fig. 1109, white-grey, with three pairs 

 of oblique black bands, whereof the first pair are short and not 

 united with each other; the two next bands, situated in the midst 

 of the abdomen, are curved forwards and united so as to form a A , 

 thickened at the sides of the abdomen and there curved outwards, 

 inside which a finer and more indistinct dark A is perceptible; the 

 third pair of bands forms a figure similar so the second, but smaller. 

 Or else the back of the abdomen in E. cingulatum % is black, with a 

 white, backward curved, transverse band in the extreme front, two 

 broad, oblique, white bands, with their points more curved forwards, 

 in the middle, and a white patch on each side of the mamillse; along 

 the middle of the back extends a band of greyish scales with a me- 

 tallic lustre varying in red and green, commonly forming small an- 

 gular marks between the larger white bands. This pale central 

 band I have not observed in E. scenicum. It is generally indistinct 

 even in the male, of E. cingulatum, in which the abdomen is most 

 commonly white above, with a broad, black, longitudinal central band 

 with deep triple indentation on both sides. — The vulva consists of 

 a rounded fovea much smaller than in E. scenicum, and the posterior 

 margin of which is divided in the middle by an incision into two 

 teeth, but not drawn out backwards, as in E. scenicum. 



E. tenevum is considerably smaller than either of the two fore- 

 going species, its cephalothorax being 1 '/ 2 millim. or at the ut- 

 most 2 millim. long. The male is easily recognized by the palpi, 

 which are yellowish, with the patellar joint only half as long again 

 as it is broad, having the tibial joint's process directed forwards and 

 but slightly outwards, obtuse arid almost straight, scarcely curved in- 

 wards ; the under margin of this process is dilated into a very broad 

 angle bent inward, so that the process, seen from the under side, 

 appears obliquely and broadly truncated at the extremity, and se- 

 parated by a triangular incision from the apex of the tibial joint 

 itselt. The lamina is short, abruptly deflected at the extremity,
