ever been recorded from the Philippines. It seems likely that 

 Buckton has made a wi'ong generic diagnosis, but the type speci- 

 mens are not available for examination. In discussing the mat- 

 ter, Mr. Distant states (in correspondence) : 



I have not seen either Bolbonata grisea Buckt. or the two following 

 species which he describes from the Philippines. They are clearly not 

 congeneric with Bolbonota. 



Buckton, however, apparently recognized the fact that these 

 forms did not fit exactly into the genus to which he assigned 

 them, for in a footnote ^ he mentions "the different appearance 

 and the non-spatulate tibiae" of these species and suggests "a 

 new genus called provisionally Xanthosticta" to include them. 

 For purposes of cataloguing it seems necessary to erect this genus 

 for the accommodation of the species under discussion, since it 

 is clear that they cannot be correctly assigned to Bolbonota. 



Xanthosticta grisea Buckton. 



Bolbonata grisea BuCKTON, Mon. Memb. (1903), 63, PI. 9, fig. 7. 



The species has never been recognized since the original de- 

 scription, which follows : 



Smaller than B. luzonica, the next species to be described; colour ashy- 

 grey; pronotum without dorsal carinations; tegmina one-third pale from 

 the tips, the other two-thirds dark brown; abdomen with the segments 

 edged with white. 



The legs both of this and B. hczonica show but little of the spatulate 

 character seen in the ordinary species of Bolbonota. 



Size in expanse of the wings, 6x3 mm. 



Habitat. — Philippines. H. Cuming. (Hope Coll.) 



Xanthosticta luzonica Buckton (Westwood in Hope coll.). 



Bolbonata luzonica Buckton, Mon. Memb. (1903), 64, PI. 9, fig. 8; 

 ibid., 75. 



Like the preceding, this species is known only by the original 

 description of Buckton, which follows : 



Head wide with prominent eyes; pronotum with a sharp pointed apex; 

 the dorsal part with three rough carinae separated by deep furrows or 

 sulci; tegmina roundish, orange-brown with whitish tips followed ' by 

 brownish stains near the apices; one-third near the base dark brown; 

 wings delicate and hyaline, with four radials and no limbus. 



Expanse, 7x3 mm. 



Taken by H. Cuming, Esq. in the Philippine Islands. 



It is named by Westwood in the Hope Coll. 



Xanthosticta trivialis Buckton.
