106 ON THE GENUS HELOTA. 



Sédillot ticketed: »coll. Thomson. Thibetana Westvv. = Mellyi 

 Westw. Thibet", but this determination certainly is incor- 

 rect. The specimens from Mr. Janson's collection have 

 been examined by Mr. Olliff , and one of the females has 

 been figured in the Cistula Entomologica (III. pi. 3, fig 1). 



The other species, which has the anterior elytral spot 

 between the 4th and 6th , and the posterior spot between 

 the 3rd and 6th striae, is the species the male of which 

 has been described by Mr. R. Oberthu'r under the name 

 of Helota curvipes. Besides the two type-specimens , which 

 have likeAvise been examined by Mr. Olliff and one of which 

 comes from the Himalaya , I have before me a third male 

 from North India from the collection of Mr. Sédillot, and a 

 female specimen from Tenasserim (brought home by Mr. Fea) 

 and belonging to the Genoa Museum. 



Guerinii Hope and curvipes Oberth. , though closely allied , 

 are not only distinct by the different position of the elytral 

 spots: in curvipes the fulvous colour of the anterior angles 

 of the pronotum is indistinctly continued along the lateral 

 margins of the thorax , the punctuation on the pronotum 

 is less dense, and the row of strong punctures which is 

 present on the interstices of the external half of the elytra 

 in Guerinii is absent in curvipes. Moreover the apices of 

 the elytra in the females are much more produced and 

 more acutely pointed in Guerinii than in curvipes. 



As to the Javanese Helota ocellata Rits. , of which only 

 a female (the type-specimen) is known to me , it has a 

 shorter and broader form , a much brighter colour on the 

 upper surface (bright golden green , with coppery tinges 

 at the sides of the pronotum and around the elytral spots), 

 the elytral spots proportionately large, the anterior one appa- 

 rently between the 3rd and 7th, but in reality between the 

 4th and 7th striae , the posterior one between the 3rd and 7th 

 striae , and the fulvous colour of the anterior angles of the 

 pronotum indistinctly continued along the lateral margins of 

 the thorax. The apices of the elytra are less produced than 

 in the female of Guerinii, but more acutely pointed than 



Xotes from the Leyden Museum, Vol- XI.
