Helota costata, var. stigma Rits. cf and Q. 



Differing from the typical costata Rits. in the following 

 points : the fulvous basal half of the elytra shows a black 

 stripe not only between the 3 rd and 4 th striae, but also 

 between the 2 nd and 3 rd and 5 th and 6 th striae; the black 

 along the sides of the elytra approaches nearer to the 

 base, ending just beyond the shoulders; a fulvous stripe is 

 present on the middle of the black apical half of the 

 elytra between the 4 th and 5 th striae; the legs show a 

 greater extend of the fulvous colour, the greater part of 

 the femora being fulvous and the tibiae being provided 

 with a fulvous ring. 



Hab. East Africa : either Usambara or Dar-es-Salam. — A 

 male-specimen in the Leyden Museum and a female one 

 in the Berlin Museum. 



Obs. Mr. Oberthiir's collection contains a female-specimen 

 from German East Africa which agrees perfectly with the 



Notes from tlie Leyden Museum , Vol. XXV.
