This genus can only be distinguished by the shape of the $ forceps from 

 Forficula,i\i% typical genus of the group. In Forficula the forceps have the 

 branches strongly flattened and dilated at the base, and then slender and 

 converging. 



I have given my reasons* for retaining Westwood's names. 

 1. Size small. Elytra dark-coloured. For- 

 ceps short (simple in $). (Wings 



abortive) 1. ARAGHIDIS, Yers. 



I'l. Size medium. Elytra golden-yellow. 



Forceps long " 



2, Wings developed. Forceps $ with 

 no tooth. Lateral folds well devel- 

 oped 2. BIPARTITA, Kirb. 



2*2. Wings abortive. Forceps $ with a 

 blunt tooth near the apex, lateral 



folds faint 3. CINGALEN8IS, Dohrn. 



APTERYGIDA ARAGHIDIS (Yers.), 



Dark-brown or castaneous, hairless. Antennae with 12-13 segments. 

 Pronotum squared, with the lateral margins paler, and the posterior margin 

 straight. Elytra free, black or reddish, the hinder margins truncate. Wings 

 abortive. Feet testaceous. Femora sometimes with a blackish band near 

 the base. Abdomen glabrous, each segment with a very short pubescence 

 at the hinder margin, segments 5 to 8 in the $ and sometimes alto the 

 forceps, slightly punctulated. In the $ the anal segment is subquadrate, 

 impressed in the middle, with no tubercles ; the forceps have the 

 branches remote at the base, short, slender, cylindrical, gently incurved 

 with a very small tooth on the inner margin at the base itself, and 

 another in the apical third. In the 9 the anal segment is the same as in 

 the male ; the branches of the forceps are short, curved in towards the apex.
