rigilans With (6, p. 475), in which the tuberete in the one specimen 

 of two was provided with a stout spine in addition to a few granules, 

 while the tuberete of the other specimen had no such spine. The 

 last character, taken from the structure of the palps, can not be re- 

 garded as a naturai one in the defini tion of this genus, when we re- 

 member, that the patella of the palps is almost simple in Hypsibunus 

 Digilans With. It seems thus evident that the genus Verpulus Sim. 

 must disappear and be considered as a synonym to Hypsibunus Thor. 

 The lattei* genus is according to Thorell (2, p. 679) different from 

 Zaleplus Thor. by « tuberculo oculorum altissimo, etiam e fronte viso 

 aliore quam latiore ». But we can scarcely regard this characte- 

 ristic as quite sufficient, when it is taken into consideration, that the 

 tuberete of Zaleplus hirsutus With is almost as high as broad, seen 

 from the front, and that we find a similar high tuberete in some species 

 of Gagrella, f. inst. G. nobilis With (6, p. 489) and G. paupera n. sp. 

 (p. 7). The genus Ceralóbunus Thor. diflfers according to Thorell 

 (1889, 1, p. 616) « a Zaleplo tuberculo oculorum bi-vel quadri-corni > ; 

 but the faets, that Ceralóbunus brevipes With (6. p. 478) has four or 

 six (five) thorns, and that Hypsibunus uigilans With (6, p. 475) has 

 two thorns or none, show that this characteristic fails. It seems 

 evident to me, that the three genera Verpulus Sim., Hypsibunus Thor. 

 and Ceralóbunus Thor. can not be regarded as naturai, and ought 

 consequently to be regarded as synonyms to Zaleplus Thor. When 

 I in the following use the terni Zaleplus Thor., it is in this wider 

 sense. This genus is according to Thorell (1889, 1, p. 609, and 1891, 

 2, p. 678) characterized by its unarmed scutum and rather long legs ; 

 but the lattei' character must disappear, when we take into conside- 

 ration, that the legs of Zaleplus minulus With (p. 481) and Ceraló- 

 bunus brevipes With (p. 478) have exceedingly short legs. Thorell's 

 genus Melanopa Thor. can not, as already shown (6, p. 483), be main- 

 tained and must be regarded as a synonym to Gagrella Stol.; the 

 cheracteristic of the lattei* genus is thus found in the armature of 

 the scutum with a single or with two spines, for the length of 

 the legs, which are long or rather short, has scarcely any syste- 

 matic valile. The single character, in which the two genera Gagrella 

 Stol. and Zaleplus Thor. differ from each other, namely that found in 

 the armature of the scutum, is according to my opinion not quite 

 sufficient for the definition of two genera, because the number of the 

 spines is not quite Constant within the sanie species of Gagrella Stol. 

 e. g. G. imperalor With (B, p. 501) and G. sepia Loman (6, p. 505), and 

 the scutum is in Zal. minulus With sometimes provided with a low 

 tuberete. The genus Scolomenia Thor. is according to Thorell (1, 

 p. 66 1) related to Melanopa Thor. and only different « alia forma tu-
