reaching but little over the apex of the bulbus, which is egg-shaped, 

 pretty strongly arched along the inner side, slightly depressed at 

 the extreme apex, and exhibits on the inner side a longitudinal 

 furrow. The mandibles are shorter than in the preceding species, 

 only y a — 3 / 4 as long as the cephalothorax. — The female is diffi- 

 cult to distinguish from E. cingulatum ? by any other criterion than 

 her smaller size, and the more purely white colour, unsullied by 

 any grey tint, of the abdomen (see C. Koch's fig. 1113). The whole 

 upper side of the cephalothorax is thickly covered with scales of a 

 reddish metallic lustre between the white marking, which is exactly like 

 that of E. cingulatum; the sides and belly of the abdomen are thickly 

 clothed with white scales; the back also is white, with three ob- 

 liquely posited black bands or patches on both sides of the reddish 

 grey band along the middle, which band for the most part is re- 

 solved into alternating reddish grey and white angular marks. The 

 vulva seems to be of about the same form as in E. cingulatum, jud- 

 ging from two (dried) specimens, which have been communicated to 

 me by Mr Westring: it appears to consist of a rounded fovea close 

 to the rima genitalis, and its pale margin is, behind, divided in the 

 middle by a triangular incision into two teeth inclined somewhat 

 backwards (?). 



In the male of Callieth. tenerus Sim.'), the patellar joint of the 

 palpi is double as long as is it broad; the tibial joint is nearly 

 such as in E. tenerum, but its process is pointed and at the extremity 

 curved inward; the inferior margin of the process is angularly di- 

 lated, as in E. tenerum, but the angle is smaller and sharper than 

 in that species, only occupying a part of the margin, so that the 

 process, seen from the under side, is broadly emarginated between 

 the extremity and the angle. The bulbus, which is scarcely depressed 

 at the apex, has a little low, oblong, shining tubercle at the outer 

 margin nearer the base. The scales of the body are much coarser 

 than in E. tenerum, and also the colour is different. (Cfr. Sim., loc. 

 cit.). Simon's statement, that the tibial joint "ne presente pas d'apo- 

 physe proprement dit, mais il est simplement elargi et un peu dilate 

 du cote externe", is, as may be seen from the above remarks, quite 

 erroneous.
