Homotoma bilineata sp. nov. Plate I, fig. 1. 



Length of body, 2.3 millimeters; length of forewing, 2.9; 

 width, 1.2; width of head, 0.67. General color black; forewings 

 hyaline with two prominent black stripes joined at base and 

 diverging in a V-shape. 



Head short, as broad as thorax, deeply cleft in front, with 

 eyes large and prominent; vertex about twice as broad as long, 

 shining black and sparsely hairy; gense very slightly swollen, 

 but not wholly covering frons; antennae not quite as long as 

 body without wings, nearly four times as long as width of head, 

 very thick and conspicuously hairy, with several very finely 

 serrated carinae on each segment; two basal segments large and 

 thick. 



Thorax not arched, relatively narrow and not robust, sparsely 

 covered with long hairs. Legs moderately thick, but not very 

 long. Forewings rhomboidal in shape, about two and a half 

 times as long as broad, hyaline, with a black spot in clavus and 

 a black stripe beginning at base of basal vein, dividing at junction 

 point of cubitus and media into two stripes and the two extending 

 and diverging toward apex of wing. 



Abdomen long and slender. Male genital segment relatively 

 small; forceps arched, about as long as anal valve, broadest 

 subapically, and rounded at tip, somewhat hairy. 



Luzon, Laguna, Mount Maquiling {Baker), 1 male. 



In general aspects this species resembles Homotoma pacifica 

 Crawford ; but in the shorter antennse, in wing shape, and in wing 

 markings it is quite distinct. 



Genus CARSIDAROIDA novum 



Head much less deeply cleft in front than in Carsidara; vertex 

 large, more or less quadrate, flattened ; gense covering frons and 

 meeting vertex above antennal bases, with anterior ocellus at 

 junction point and appearing to be in middle of vertex because 

 of obscurity of suture between vertex and gense; gense swollen 

 beneath antennal sockets, but without genal cones. Antennae 

 long and slender. Labium very long and slender and prominent. 



Thorax not much arched, broad; pronotum long. Legs long 

 and large; hind tibise with a spur at base and spines at apex. 

 Forewings long, venation similar to that of species of Carsidara; 

 with a callus (pseudovein) connecting medial and radial veins 

 as in Tenaphalara and in Carsidara. 



Type of genus: Carsidaroida heterocephala sp. nov. 



Although this species differs from species of Carsidara in 

 having the head less cleft in front, yet the position of the anterior
