IIELOTA MARGARETIIAE. 27 



NOTE III. 



TWO NEW SPECIES OF THE GENUS HELOTA FROM 

 BRITISH BHOTAN 



lESCRIBED BY 



C. RITSEMA Cz. 



Helota Margarethae, n. sp. (ƒ and 9« 



Amongst the numerous examples of Helota Marias Rits. 

 communicated to me by Mr. Rene Oberthür after the des- 

 cription of this species was published '), and which came 

 all from the same locality viz. Maria Basti in British Bho- 

 tan, I found a certain number of specimens which have 

 the tibiae bicolorous, not entirely dark bronze as in Mariae. 

 A careful examination convinced me that these specimens, 

 though closely allied to Helota Mariae, belonged to an 

 undescribed species for which I propose the specific name 

 Margarethae. 



Besides by the coloration of the tibiae this new species 

 is differentiated from Mariae by a somewhat larger size 

 (especially observable in the male sex) and somewhat larger 

 elytral spots, by the more strongly transverse prothorax, 

 by the more elongate anterior tibiae of which, moreover, 

 in the male the dilatation at their apical half is otherwise 

 shaped and finally by the want of the small but distinct 

 tooth near the end of the inner edge of the middle- and 

 hind tibiae in the male. 



Length 8 — 9 mm. — Subshining; above dark bronze,
