It is closely allied to G. nigripennis, and the labium agrees with the 

 description of that species. The head and prothorax are not darker than, 

 the fore wings, and the bands on the bind wings are on both sides of the 

 transverse veins. 



21. GltVLLACRIS DISCOIDALIS. 



Mas. Lutea; frons subsulcata ; palpi pallide teslacei ; antenna: gracil- 

 limce, corpore plus Iriplo longiures ; prothorax sulcis duobus obliquis 

 sulcouue transverso antico ; pedes robusti ; ala anticce pallide testacea ; 

 alee poslica nigricantes, albido guttata: et marginata. 



Male. Luteous, smooth, shining. Head a little broader than the 

 prothorax, with a shallow furrow between the sockets of the antenna?. Eyes 

 blackish, prominent. Palpi pale testaceous; fifth joint of the maxillary 

 palpi subclavate, truncated at the tip, a little longer thau the fourth; apical 

 joint of the labial palpi capitate. Antenna; very slender, more than thrice 

 the length of the body. Prothorax transverse, with an oblique furrow on 

 each side and a transverse furrow near the fore border, which is slightly 

 arched. Cerci less than one-fourth of the length of the abdomen. Legs 

 stout; hind femora with about nine small spines on each side, these spines 

 successively increasing in size to the apical one; hind tibia; with eight 

 rather short spines on the outer side and with seven aheruale spines on the 

 inner side. Fore wings pale testaceous, a little shorter than the hind 

 wings; veins luteous. Hind wings blackish, whitish only along the costa 

 and along the exterior border; the six bands are elsewhere confluent and 

 include four rows of whitish dots; the seventh baud is distinct from the 

 others; the submarginal line of transverse sectors has no band. Length of 

 the body 12 lines ; of the wings 36 lines. 



It shows a transition between the species with dark bands and those 

 with pale bands. It has most affinity to G. maculicollis.
