ON THE GENUS HELOTA. 99 



NOTE XXIV. 



PRELIMINARY DESCRIPTIONS 



OF NEW SPECIES OF THE COLEOPTEROUS GENUS 



HELOTA, MACLEAY. 



BY 



C. RITSEMA Cz. 



Having the intention to publish at some future date full 

 descriptions (perhaps also figures) of all the known spe- 

 cies of the genus Helota Macleay [the only species which 

 are still unknown to me, are Helota thibetana Westw. 1 } 

 {== Mellii Westw. 2 j ) and Helota ajricana Olliff 3 )], I will 

 confine myself for the present time to give the distinctive 

 characteristics of the new species with which I am as yet 

 acquainted. 



Before going over, however, to the descriptions of these 

 new species, I feel obliged to state, judging from the spe- 

 cimens in the collections of Mr. E. W. Janson 4 ), Mr. R. 

 Oberthür and in the Leyden Museum which are now before 

 me and which are determined by Mr. A. Sidney Olliff , 

 that this author has overlooked the specific distinctness of 

 my present Helota Oberthüri and Fairmairei from Helota. 

 Servillei Hope, that of my present Helota Kolbei from his 

 Helota Gorhami, that of Helota fulviventris Kolbe (at that 

 time undescribed) from Helota gemmata Gorh. , and that 

 of my present Helota fulvitarsis from Helota semifulva Rits.
