HELOTA BOYSII. 189 



NOTE XXXVI. 



ON AN UNBESCRIBED SPECIES OF THE 

 COLEOPTEROUS GENUS HELOTA, MACLEAY. 



BY 



C. RITSEMA Cz. 



To the liberality of Prof. Westwood I owe the oppor- 

 tunity of adding a new species of Helota to the number 

 already described , and as the specimen communicated to 

 me (a cT) is labelled » Helota Boysii Westw." , I believe it 

 desirable to maintain this name. 



Helota Boysii 



is a very narrow and elongate species, and closely allied 

 to H. pusilla R. Oberth. l ) and culta Olliff 2 ) of which I 

 have the types before me. It is, however, considerably lar- 

 ger, measuring 9 mm. in length, which gives it some re- 

 semblance to H. laevigata R. Oberth. 3 ). The latter, how- 

 ever, is broader, has a shorter thorax and otherwise coloured 

 antennae, sides of prosternum , elytral epipleurae 4 ) and 

 legs, and its tibiae are considerably more elongated. More- 

 over the tibiae of the anterior pair of legs in the males 

 are quite differently shaped : in laevigata cf they are more 

 elongated (as is already said), and distinctly curved about 

 the middle; in Boysii cf on the contrary they are shorter 

 and stouter, slightly curved at the apex on the out- 

 side, and provided at the apex on the inside with a flat- 

 tened and truncate black appendage which is directed for-

4) In laevigata the sides of the prosternum and the elytral epipleurae are pale 

 fulvous (the latter with a brassy hue), in Boysii, pusilla and culta they are brassy.
