 8, p. 19, 1927. 



This is the genotype and only known species of the genus. The 

 head is yellow, with three black spots on frons and four on face; an- 

 tennae and palpi yellow. Thorax and scutellum yellow, dorsum with 

 four broad brown vittae which extend over scutellum, pleura with 

 two similar vittae. Abdomen reddish brown, with sides black brown. 

 Legs yellow, femora at bases more or less brown and before the apices 

 with a brown ring, all tibiae with three brown rings, fore tarsi en- 

 tirely, and apical segment of other tarsi, black-brown. Wings con- 

 spicuously marked with brown, in the form of two longitudinal 

 streaks, the first over the costa, the second over the fifth vein, the 

 costal one with a pale streak and two spots in it, the posterior one 

 irregular and more or less broken with pale spots. 



Length, 6 mm. 



Localities. — Surigao and Siargao, Mindanao. 



APPENDIX 

 GRIPHOMINETTIA, new genus 



This genus has the face as in Minettla longip&nnis Fabricius, with 

 two f)ronounced humps on lower half, and also has the intra-alar 

 bristle strong, and the costal setulae as in that genus. The fourth 

 wing vein is strongly curved forward near its apex, forming a broadly 

 rounded bend as in Griphoneura and most species of the subgenus 

 Griphoneuroides of Homoneura^ the first posterior cell being almost, 

 or quite, closed at margin of wing. The fore femur lacks the pre- 

 apical anteroventral comb of minute black setulae, which is another 

 feature distinguishing the genus from Homoneura. 



Genotype. — The following species. 



GRIPHOMINETTIA SUMATRANA, new specias 



Male. — Head black, centre and anterior margin of frons brownish; 

 antennae fuscous, second segment 3'ellowish; palpi black. Thorax 

 black, shining, slightl}'^ gray dusted; humeral angles, anterior and 

 posterior portions of pleura, the postalar region, and the metanotum, 

 fulvous yellow. Abdomen glossy black, hypopygium brownish. Legs 

 yellow, tarsi, and especially the fore pair, darkened. Wings hyaline, 

 veins brown, yellow at bases. Calyptrae and halteres yellow. 



Frons a little longer than wide, all bristles long; face widened be- 

 low ; third antennal segment about twice as long as wide ; arista with 

 its longest hairs not as long as width of third antennal segment ;
