SOME MALAYAN DELPHACIDJE (HOMOPTERA)

ONE PLATE 



This paper deals with a few of the specimens of Delphacidse 

 recently collected by Prof. C. F. Baker. I hope in the near 

 future to be able to report on the remainder of the collection. 



The more I study this family the more I am convinced that 

 the tibial spur must form the chief characteristic for the pri- 

 mary division, although it may appear to be, at times, more 

 artificial than natural. Any other one character is still more 

 unsatisfactory. 



The types of the new species described in this paper are 

 deposited in the collection of the Hawaiian Sugar Planters' Ex- 

 periment Station, Honolulu, H. T., and the paratypes, when 

 present, in the Baker collection. 



Genus PTJKOHITA Distant 



Purohita nigripes sp. nov. 



Male. — Macropterous ; width of vertex at base slightly more 

 than length, base slightly behind middle of eyes, twice width 

 of apex; basal joint of antennae 1.5 times the length of second. 



Very light brown; apical half of face, gena?, and lateral mar- 

 gins of pronotum whitish, a dark brown line dividing the white 

 lateral portion of pronotum from the rest, darker brown over 

 abdominal tergites, a dark longitudinal mark on first and second 

 femora, tarsi of those legs black or dark brown. Tegmina 

 hyaline, slightly opaque, veins white with irregular black spots, 

 a dark brown mark over cross veins, not quite reaching to inner 

 margin and fading out toward apex; wings hyaline, slightly 

 opaque, veins light brown. 



Lateroventral edge of pygophor produced into a small, obtuse 

 angular process; genital styles straight on inner margin and 

 on outer margin for basal two-thirds, then tapering to the acute 

 apex, which is curved outward.
