A NEW PHILIPPINE GENUS OF DELPHACID^ 



By Frederick Muir 

 (Honolulu, Hawaii) 



Genus VIZCAYA novum 



Head narrower than thorax; vertex longer than broad (1.70 

 to 1), base slightly wider than apex, mediolateral carinse meeting 

 well before the apex, Y-shaped carina obsolete, length of face 

 nearly two and one-half times the width at apex (1 to 2.4), apex 

 wider than base, sides nearly straight, lateral carinse distinct, 

 a single median carina faint on apical half and obsolete on basal 

 half, a distinct carina across gena from base of antenna to the 

 lateral corner of base of clypeus; clypeus shorter than face, 

 tricarinate; head in profile rounded at junction of vertex and 

 face. Antennae nearly twice the length of head and pro- and 

 mesothorax together, second joint more than one half longer 

 than first (1.6 to 1), first joint flattened, wide, thin, second 

 joint terete, evenly covered with raised sense organs and short 

 spines. Hind margin of pronotum slightly and evenly emargi- 

 nate, carinse obsolete; mesonotum with three very fine carinse. 

 Legs long and slender, hind tibise with one basal, one medio- 

 apical, and five apical spines; hind tarsi not quite half the 

 length of tibia, basal joint longer than the other two together 

 (1 to .70), spur not as long as the basal joint, cultrate, convex 

 on both sides, seven teeth on hind margin and one at the apex. 

 Tegmen long, narrow, median vein not touching the radius. 



This is a very distinct genus belonging to the Alohini and 

 coming nearest to Proterosydne. It has some affinity, at least 

 superficially, to Lanaphora of the Tropidocephalini. 



Vizcaya bakeri sp. nov. 



Male. — Orange or ochraceous orange; vertex (except a trian- 

 gular patch at each corner of base), base of face, and base of 

 clypeus shiny black, antennae dark brown, second joint darkest, 

 tarsi fuscous, abdomen dark brown or black. Costal area to 

 near apex and basal third of tegmen hyaline, rest of tegmen 

 dark fuscous, darkest over apical third and fading toward base, 

 veins concolorous with membrane, very fine granules bearing 

 fine black hairs.
