224 IIELOTA ATTENUATA. 



NOTE XXV. 



DESCRIPTION OF THE MALE SEX OF 

 HELOTA ATTENUATA RITS. 



C. RITSEMA. Cz. 



Helota attenuata belongs, together with Dureli, Moutoni 

 and Helleri, to the group of Helota rotimdata (see my 

 „Synopsis" in Notes Leyd. Mus. Vol. XIII, p. 227). It is 

 easily recognizable among these species by the coarse 

 punctuation on the pronotum and by the reddish testaceous 

 colour of the elytra! epipleurae. 



When I described the species, the female sex only was 

 known to me (Notes Leyd. Mus. Vol. XVI, p. 112), but 

 later on Mr. René Oberthür received also the male sex 

 from the environs of Kurseong (R. F. Bretaudeau) and 

 from Maria Basti and Padong in British Bhotan (R. F. Durel). 



The male is somewhat narrower in shape than the female, 

 but the punctuation quite agrees and the apices of the 

 elytra are likewise almost conjointly rounded. The anterior 

 tibiae are much curved and their inner lower margin is 

 deeply and regularly notched about the middle; between 

 the notch and the apex the tibia is broader and the margin 

 of the dilated portion is regularly convex. The intermediate 

 and posterior tibiae are slightly waved, visibly thickened 

 in their greater apical half and covered beneath with a 

 soft almost colourless pilosity. The apical ventral segment 

 is broadly truncate posteriorly and provided in front of 

 the truncation with a bald, finely punctured, very shallow 

 impression; the lateral angles of the truncation are dark 

 coloured and slightly raised.
