Epicauta canescens var. elunda Wellm. var. nov. 



Vitta dorsali elytrorum nulla. 



Typ. in coll. mea. 



The absence of the most prominent marking gives the insect a strik- 

 ingly different aspect. The name is a local word referring to the place 

 in which the type of the variety was found. 



Seventy-eight specimens of this species taken in November, 1907, 

 and February, 1908. It is usually found wandering aimlessly about 

 on the ground, but I have taken it eating potato tops and also bean 

 leaves. It is often mentioned by the natives as destroying their crops. 

 I once found them eating the young tender sprouts of a coarse branching 

 grass {Eragrostis sp.).

 Lacordaire {Gen. Col., V, p. 683) suggests regarding the type (said 

 to have been found in England) of this genus that it "pourrait bien 

 etre d'origine exotique." I have examined the insect (*S. immunis 

 Steph.) in the British Museum and believe that this must certainly 

 have been the case.
