HEMIPTERA— CICADELLIDAE (JASSIDAE). 



171 



Species included in tlie genus have now been recognised from Eastern 

 Palaearctic, Ethiopian and Oriental Regions, as Avell as the Nearctic and 

 Neotropic. 



9. Xestocephalus pardalinus Distant. 



Xestocephalus pardalinus Distant, Fauna Brit. Ind. Bhynchota, IV, Pt. 2, p. 348, 1908. 



In this species, as defined by Distant, there is a distinct colour pattern and 

 a well-marked dark line above and below the ocelli, including a pale area within 

 which the ocelli are located. Except for the more distinct colour marking and 

 a slight difference indicated in size (which may be a variable character) there is 

 little to separate the species from apicalis of Melichar. However, specimens 

 agreeing very perfectly with Distant's description (and type in British Museum) 

 of specimens from Ceylon, Maskeliya, and bearing labels " Upolu Is., Malololelei, 

 2,000 ft., xii.1925, and vi.l924, P. A. Buxton and G. H. Hopkins," and one 

 " Savaii, Saitalus, v-17-24, Rain Forest, 2,000-4,000 ft., E. H. Bryan collector," 

 are among the specimens referred to me and I am therefore including the record 

 under this name. If future studies prove the species to be identical Melichar's 

 name has priority. 



10. Xestocephalus apicalis Melichar. 



Xestocephalus apicalis Melichar, Horn. Fauna, Ceylon, p. 207 (1903). 



Xestocephalus apicalis Distant, Fauna Brit. Ind. Rhynchota, IV, Pt. 2, p. 349 (1908). 



The Samoan specimens agree well with Melichar's description with only 

 slight variations in extent or intensity ©f colour pattern. Pour from Malololelei, 

 Upolu, 2,000 ft., vi.l924, Buxton and Hopkins ; one Malololelei, Upolu, 2,000 ft., 

 vi.l924 ; one Tutuila, 760-900 ft., Kellers, iv.l918 ; one Tutuila, Afona Trail 

 9-25-1923, Swezey ; one Savaii, Salailua, v-17-1924, Rain Forest, 2,000-4,000 ft., 

 Bryan. 



Considering the apparent wide distribution now accorded the species and 

 the habitat indicated, the variation noted does not seem unusual. The specimens 

 listed above merge almost into the paler form of what I have taken to be the 

 fardalinus of Distant. See ante.
