and slightly impressed at the apex, and behind this another very 

 small elevation or tubercle. The palpi of (f of E dentipalpis and 

 E. vagubunda or atra Blackw. (see next page) are evidently shorter 

 than in the case of E longipalpis, which on the contrary is usually 

 of a larger size than either of the other species. For farther parti-

Reuss' description (loc. cit.) of the male's palpi appears to me 

 to agree best with E. dentipalpis Westr.; nevertheless Recss' 1'hev. 

 dentipalpe, as well as C. Koch's E. dentipalpis, appears also to include 

 E. atra or vagubunda, and perhaps even E. longipalpis: one of these 

 would at least seem to be indicated by the circumstance, that neither 

 Koch nor Reuss mentions or figures the tooth on the under side of 

 the tibial joint's inferior apophysis in the d\ which is always met 

 with in E. dentipalpis, but is absent in both the allied species. The 

 presence of that tooth in the figure in Spid. of Gr. Brit., to which 

 we have referred in the Synonyms, shows, that Beackwall in that work 

 included E. dentipalpis under his Ner. longqmlpis. — Westring has 

 already remarked that C. Koch curiously enough does not mention any 

 spine-armature on the edge of the cephalothorax of his E. dentipidpis.
