A iNEW SPECIËS OF TESSAHATOMIN/E 

 (HEM., PENÏATOMID.-E) 



bj E. lterp;rolh. 



The species described below gives at first sight the impression 

 of beloiiging to a new geiius, but afler a close examination of ils 

 characters I find Uiat it cannot be separated from Hypencha Am.S. 

 in spite of the excessive development of the humerai processes. 

 In the three first described species of this geuus the humerai angles 

 are broadly rounded and but slightly prominent, but later two 

 species {opposita Walk. and alata Bredd.) hâve been described, in 

 which the humerai angles are distinctly angularly dilated, although 

 not nearly so much as in the new species. Also in the Tessaratomine 

 genasEinbolosternaSTÂLy in which the humerai angles are produced 

 in long horns, one species is known (E. vacca Mart.) having thèse 

 angles broadly rounded and scarcely prominent. Great diversity in 

 the development of the humerai area we find also in the numerous 

 species of the allied genus Pyqoplatys Am. S.
