DESCRIPTIONS OF TWO NEW SPECIES 



OF HERMESIA (CHRYSOMELIDAE , FAM. EUMOLPIDAE) 



BY MARTIN JACOBY 



Amongst the insects obtained by Sig. Boggiani at Paraguay 

 of which I iiave lately described the Phytophaga in these An- 

 nals, I find that I have overlooked a species of Hermesia which 

 seems to be new to science and of which I give the description 

 here, together with another species of the same genus contained 

 in my collection. 



Hermesia aenea, sp. nov. 



Obscure aeneous, the basal joints of the antennae and the 

 base of the femora more or less flavous, thorax finely punctured, 

 more closely so at the sides, elytra strongly subgeminate punctate 

 near the suture, more irregularly so at the sides, the interstices 

 at the latter place transversely rugose. 



Length 4 mill. 



Of oblong shape, the head variegated with purplish and cu- 

 preous colour, minutely granulate, the vertex remotely punc- 

 tured, deeply longitudinally sulcate between the eyes, the latter 

 round and large, clypeus separated from the face, more strongly 

 punctured, its anterior edge semicircularly concave at the middle, 

 base of the antennae smooth, greenish aeneous, antennae nearly 

 extending to the apex of the elytra, the basal five or six joints 

 flavous , the others piceous , third and fourth joint equal , the 

 fifth slightly longer ; thorax strongly transverse , more than 

 twice as broad as long, the sides strongly obliquely narrowed 

 anteriorly (reducing the anterior margin to half the width of
