Mandibles: galea straight, in 9 long with some small teeth near 

 the extremity, in d shorter and without teeth. 

 Legs: claws simple. 



Length : up to 2 3 / 4 mm, full grown specimens can, however, be 

 considerably smaller. 



Valle del Mira, near La Concepcion 9 specimens. 

 The only difference of any weight between Balzan's description 

 and figure on one side and the specimens from Ecuador on the other 

 is the colour and the longitudinal line on the upper and lower surface 

 of the abdomen. According to Balzan the colour should be reddish, 

 the specimens from Ecuador are dark brown till nearly blackish browni 

 but the specimens from Ecuador are also larger and most likely more 

 developed, having got to a higher degree their final colour, than Bal- 

 zan's few (3) specimens. More to be considered is, that the longitudinal 

 line on abdomen, according to Balzan, shall be « sottilissimo e, spesso, 

 quasi invisibile»; on the specimens from Ecuador this line is very 

 broad, rather ribbonlike, but this difference may depend on Balzan's 

 specimens having been very strongly contraeteci, what is often the 

 case with Chernes and Chelifer. Owing to the dark colour of the 

 sclerites and the pale interstitial parts as well longitudinaliy as tran- 

 sversally, several of the specimens from Ecuador are very beautifully 

 coloured. In the shape of the palps and the galea the specimens from 

 Ecuador are quite alike the Brazilian specimens of Balzan's; indeed, I 

 have no doubt, that my specimens from Ecuador belong to his' species, 

 being at most a variety coloured in some other manner. Peculiarh' 

 enough, most of the specimens had lost almost ali the hairs. 



The same arrangement of the colours on the cephalothorax behind 

 the posterior transverse groove (and the broad longitudinal band on 

 the abdomen), this part being whitish with a small brown spot in 

 the middle, is also found, according to Balzan, in some south Ame- 

 rican species of the subgenus Chernes crassimanus, subrotundatus 

 and bicolor, but ali of these are missing eyes. Balzan's not having 

 observed this arrangement of the colours in his specimens of Ch. Ger- 

 mainii may depend on the colour of the animals having been so pale, 

 that the contrast of the colours has not been suffìciently striking, or 

 that the specimens from Ecuador are really a coloured variety. °
