282 The Philippine Journal of Science i9i8 



The present paper describes a number of species collected by 

 Mr. Leopoldo B. Uichanco and transmitted for study by Prof. 

 Charles S. Banks, College of Agriculture, University of the 

 Philippines. The collection contained but fourteen species, all 

 new. Five of these are referable to new genera, which are 

 remarkable because of peculiar structures or notable specializa- 

 tion, such, for example, as Kronodvplosis, a member of the 

 bifili easily recognized by the uniarticulate palpi; and Kampto- 

 diplosis and Heliodiplosis, two genera allied to the peculiar sub- 

 tropical Kalodiplosis Felt, though easily distinguished by the 

 fewer and relatively longer circumfila,- the greater prolongation 

 of the flagellate antennal segments of the male, and the shorter 

 palpi. 



Genus LUZONOMYIA novum 



This genus is erected for a small midge presenting close affini- 

 ties with OUgotrophus Latr., from which it is most easily sepa- 

 rated by the distinctly produced basal clasp segment of the male 

 and the small subapical terminal clasp segment. 



Type of the genus, Luzonomyia sijmphoremx sp. nov. 



Luzonomyia symphoremse sp. nov. 



Male. — Length, 1.5 millimeters. Antennae nearly as long as 

 the body, dark brov^n, sparsely haired; 14 segments, first seg- 

 ment broadly obconic, second subglobose, third and fourth weakly 

 fused, fifth with a stem one-fourth the length of cylindrical 

 basal portion, which has a length about three times its diameter, 

 a rather thick basal whorl of moderately long, stout setae, a 

 scattering subapical band of longer, slenderer setae, and low 

 circumfila at basal third and apicad; terminal segment missing. 

 First segment of palpi short, irregular ; second moderately broad, 

 with a length about twice its diameter; third a little shorter 

 than second, irregularly pyriform. Mesonotum dark yellowish 

 brown, the fuscous yellowish submedian lines sparsely haired. 

 Scutellum and postscutellum yellowish. Abdomen thickly haired, 

 dark yellowish brown. Wings hyaline. Costa dark brown, sub- 

 costa uniting, with margin at basal third, the third vein at apex, 

 fifth at distal fourth, its branch at basal third. Halteres nearly 

 uniform fuscous yellowish. Coxae a variable dark brown. Legs 

 mostly dark brown. Claws moderately long, slender, rather 

 strongly curved apicad, simple, pulvilli a little shorter than claws. 

 Genitalia : Basal clasp segment moderately long, stout, consider- 

 ably swollen near distal third, at which point the terminal clasp
