Lophocarenum elongatum Menge, in which, as Menge's figures 

 show , the head is much lower than in E. elongata Westr. , is a dif- 

 ferent species, and the same as E. parallela (Keuss), concerning which 

 species vid. infr. sub. E. parallela Westr. 



Lophocarenum dicholophum Menge. on the contrary, is probably 

 identical with E. elongata Westr. : the description and figures of the 

 male's cephalothorax and palpi perfectly suit E. elongata, only the 

 patellar joint is said to be as long as the patella of the first pair of 

 legs, whereas in E. elongata it is much longer. Menge unfortunately 

 says too little of the nature of the surface of the cephalothorax, which 

 in E. elongata is distinguished by impressed points ordered in radiating 

 rows. The skin of the back of the abdomen is of a firm consistency, 

 with large impressed points; the patellar joint of the palpus of 

 is almost as long as the femoral joint, and half as long again as the 

 patellar joint of the first pair of legs, somewhat thickened at the 

 extremity; the tibial joint is much narrower at the base, not half 

 so long as the patellar joint: its extremity is at the end, above, pro- 

 duced into a very long, fine, pointed spine strongly curved outward 

 and also upward, and, a little beneath this, dilated on the outer 

 side into a, short, blunt process. 



Lophocarenum crassipalpe Menge ') is pretty nearly related to 

 E. elongata. The cephalothorax however in L. crassipalpis Menge, 

 as in E. altifrons or acuminata Westr., is destitute of rows of im- 

 pressed points. The elevated portion of the head of <$ is almost 

 vertical, not, as in E. elongata, inclined backwards, the cephalothorax 

 very finely chagrined and bright, the skin on the back of the ab- 

 domen marked with fine impressed points. The patellar joint of the 

 palpus is little more than half as long as the femoral joint, cylin- 

 drical, only a little longer than the patella of the first pair of legs; 

 the tibial joint, narrow at the base and very short, is at its apex, 

 above, drawn out into two processes separated by a rounded notch, 

 of which the interior is long, pointed and somewhat curved out- 

 ward, the exterior is shorter and terminates in a fine point. Of 

 this species, which had not previously been met with in Sweden, 

 Dr Haglund has captured a $ ad. at Upsala. Menge's statement, 

 that the head has no side-fovese, is erroneous; for not only is the 

 above-mentioned Swedish specimen furnished with these fovese, but so 

 also is a specimen, which Menge himself had the kindness to send 

 me from Danzig.
