190 HELOTA BOYSII. 



ward and inward. Finally the pubescence of the basal joints 

 of the anterior tarsi is much longer and denser in Boysii 

 (ƒ than in the same sex of laevigata. 



From pusilla (the male sex of which is unknown to me) 

 the new species differs, besides by the sexual characters and 

 by its larger size (9 mm.) , by the pale colour of the club 

 of the antennae , by the punctuation of the head which is 

 considerably coarser and denser, by the shape and punc- 

 tuation of the prothorax (in Boysii the prothorax is pro- 

 portionately longer, more strongly narrowed in straight 

 lines to the front and consequently of a regular trapezoidal 

 shape , with broadly rounded anterior angles which are not at 

 all produced ; the punctures on the pronotum are larger , 

 more widely and irregularly spread , leaving free a longi- 

 tudinal streak in front of the scutellum ; as for the punc- 

 tuation of the pronotum it agrees therefore better with 

 laevigata than with pusilla). Moreover, H. Boysii differs 

 from pusilla in the position of the yellow elytral spots: in 

 the former the anterior as well as the posterior spot is 

 placed between the 3rd and 7th striae, whereas in the 

 latter the anterior spot is placed between the 4th and 7th, 

 the posterior one between the 3rd and 7th striae. Finally 

 in Boysii the metallic green colour on the tibiae is restricted 

 to the basal fourth , whereas in pusilla it occupies slightly 

 more than the basal half. 



From culta tf it may be distinguished by its superior 

 size , straight (not constricted) sides of the prothorax , flat- 

 tened appendage at the apex of the anterior tibiae, more 

 narrowly rounded apices to the elytra which show a mi- 

 nute sutural tooth, proportionately smaller elytral spots, 

 etc. In both species the 5th ventral segment has no im- 

 pression , and the hinder-margin is truncate , more nar- 

 rowly , however , in culta than in Boysii. 



The examined male specimen comes from India (Boys) 

 and belongs to the University Museum at Oxford.
