Walckenaee erroneously refers (Ins. Apt., II, p. 489) D. varia- 

 bilis C. Koch to his Drassus (Argus) viridissimtis. In the male of 

 D. variabilis the apex of the outer side of the tibial joint of the 

 palpus forms a tolerably strong, outstanding tooth; at the apex, to- 

 wards the outer side, the patellar joint exhibits a corner or very small 

 tooth; the basal, backward- directed process of the bulbus is, when 

 viewed from the side, blunt and curved a little downwards, but it is 

 not compressed, broader behind and at the apex broadly truncated, as 

 it is in Did. viridissima, in which moreover the little tooth at the 

 end of the patellar joint is wanting: the blunt process formed by 

 the dilated apex of the tibial joint does not stand out so decidedly 

 and toothlike in D. viridissima as in D. variabilis. In neither sex 

 of D. variabilis has the abdomen the fine green colour that distin- 

 guishes D. viridissima , both cf and \ ; and besides , D. viridissima 

 is not inconsiderably larger than D. variabilis, especially the female. 



Cambridge, who states ') that D. (Ergatis) variabilis is met with 

 in England, expresses his suspicion that E. pollens Blackw. is only 

 a variety of this species; and I am so much the more convinced 

 that he is right in this, as I have myself seen specimens of D. va- 

 riabilis with just such a dark spot on the abdomen as distinguishes 

 "E. pollens? I have however myself never seen an English specimen 

 of this form. — On D. variabilis, which is perhaps identical with 

 Drassus (Argus) fiavescens Walck. 2 ), see more farther on under D. 

 viridissima Walck.

The identity of V. lineata and U. Walckenaerii, which I loc.
