22. 2 Muir: Fulgoroidea from Sumatra 173 



Melanesia sp. 



Sumatra, PagaMaban, December, 1919 (Corporaal), 1 female. 



This appears to be an undescribed species, but the male is 

 necessary for certainty. 



Perkinsiella neoinsignis sp. nov. Plate 1, fig. 2. 



In all external characters this species agrees with the Indian 

 P. insignis (Distant), but the genitalia are quite distinct. 



Opening of pygofer longer than wide, anal emargination 

 large, anal angles not produced, medioventral margin produced 

 into a small horizontally flat process deeply emarginate in middle, 

 thus forming two flat processes ; diaphragm long, dorsal margin 

 V-shaped in middle. Anal segment large with two long, thin 

 spines with their bases far apart. Genital styles not reaching 

 to anal segment, apex truncate, narrow, inner margin straight 

 on apical half, slightly concave on basal, outer margin concave 

 on apical half, produced slightly on basal. ^Edeagus large, 

 flattened laterally, in lateral view curved, orifice on dorsal as- 

 pect of apex ; basad of orifice there are two spinelike processes ; 

 one long, flat process curved to right, the other a small process 

 slightly curved to left. 



Sumatra, Medan, 1920 (Corporaal), 1 male. Type No. 1061. 



In P. insignis the medioventral process of pygofer is much 

 broader and the two processes diverge slightly; the genital 

 styles are much narrower at apex and gradually wider to basal 

 angle; the sedeagus has two small spines about equal in size. 

 Dicranotropis corporaali sp. nov. Plate 1, fig. 3. 



Male.— Length, 2 millimeters; tegmen, 2.4. The lateral 

 carinae of pronotum diverging posteriorly but not curved; 

 median carina* of face forked about one-third from base. 

 Stramineous; mesonotum slightly sordid. Tegmina hyaline, 

 slightly stramineous, veins same color as membrane, tubercles 

 small, sparse, same color as veins bearing stramineous macro- 

 trichia. Genitalia figured. The genital styles are very dis- 

 tinctive. 



Sumatra, Medan, 1920 (Corporaal), 1 male. Type No. 1062. 



Phyllodiims platypoda (Dammerman). 



Sumatra, Fort de Kock, 920 meters elevation, November, 

 1920 (Jacobson), 1 female. 



This species was originally placed in Platybrachys Dammer- 

 man, but that name is preoccupied. Phyllodinus Van Duzee as 

 it stands at present consists of two genera and, until it is
