Type 9 from Burma ; one 9 from N. Chin Hills, Burma 

 (Watson); one 2 from Dawna Range, Tenasserim, Lower Burma, 

 500 — 1,500 feet (Bingham) ; one 9 from China in Dr. Kertesz's 

 collection. 



Type and specimens are all in a denuded faded condition, 

 so that the redescription given below is imperfect. The spe- 

 cies appears to be nearly related to Tabaims glaber, Bigot, but is 

 distinguished from it by the frontal callus. Abdomen reddish, 

 with a broad black median stripe. Length 16 mm., one specimen 

 17 mm. 



Face greyish with thick short white pubescence. Beard white. 

 Palpi reddish yellow with black pubescence, long with a not very 

 pointed apex. 



Antennae gone in type. Walker describes them as small, 

 with the tooth very small; in the specimens from Tenasserim and 

 China they are long and slender, the tooth prominent, reddish, the 

 third joint darker. Forehead considerably narrower anteriorl}', 

 about six times as long as it is wide, the frontal callus oblong, 

 narrow, nearly reaching the eyes with a short linear extension. 

 Thorax blackish, red at sides, scutelkim blackish, red on its outer 

 l)order. Abdomen appears to be reddish with a broad black stripe 

 on which appear traces of a narrow grey stripe, the sides of seg- 

 ments black and the three last segments wholly blackish. Legs red- 

 dish, the fore femora, apices of fore tibiae, and tnrsi blackish. 

 Wings clear, stigma yellowish, veins brown.
