Distribution: Philippine Is. 



Material examined: Luzon, Mt. Makiling (Baker), 1 9, topotype 

 and second specimen known (USNM). An extremely large species. 



Diploclasis, new genus 



Head ^\Titli appressed scales, side tufts moderately spreading. 

 Ocellus posterior. Proboscis developed. Antenna 4/5, in male 

 long-ciliated throughout, scape elongate, ^^-ith a brushy long pecten 

 along basal half. Labial palpus very long, porrected-recurved, 

 median segment very long, little ciu'ved, smooth, moderately thickened 

 before apex, terminal segment slender, acute, 2/3 median, rising. 

 Maxillary palpus moderate, pending, appressed to proboscis. Thorax 

 smooth. Posterior tibia smooth. 



Forewing elongate, without tufts of scales on siu"face. Vein lb 

 furcate, 2 from before angle, 3 and 4 approximated, from angle, 7 and 

 8 stalked, 7 to termen just below apex, 11 from middle. Hindwing 

 elongate-semioval, under 1, ciha 1/2; 3 and 4 connate, 5-7 tolerably 

 parallel, 5 submedian, 6 and 7 running close along basal third. 



Male genitalia as described with the species. 



Type species: Diploclasis balbidophora, new species. 



Probably allied with Tanyzancla Meyrick, but differing by long 

 ciliate antennae in male, very long median segment of palpus and 

 entnely smooth posterior tibia.
