hyaline space between the second and third bands has above near 

 the fore border a fuscous triangular spot, prolonged to the 

 second longitudinal vein, which is entirely wanting in lepido- 

 phora and in fusifacies; the prseapical band is likewise complete, 

 but there is no dark spot in the hyaline hind border of the 

 second posterior cell. 



Luzon, Tayabas, Mount Banahao (Baker). 



195. Tseniaptera nigripes van der Wulp. 1881. 



Los Banos, Mount Maquiling, Luzon. Philippine specimens 

 like the present ones have been referred by Osten Sacken to 

 this species described from Sumatra, but I think it probable that 

 they belong to an undescribed species; the rings on femora are 

 white, not reddish as in typical specimens. 



196. Eurybata hexapla 0. S. 1882. 



Luzon, Laguna, Los Banos and Mount Maquiling. A very 

 strange and beautiful endemic insect. 



Telostylus niger Bezzi, 1913. — This species, described in the 

 first century,^*^ seems to be common in the Islands, being also 

 represented from Mount Maquiling ; Professor Baker has reared 

 it from fallen fruits of Terminalia nitens Presl. 



Male. — The undescribed male is like the female, but is notice- 

 ably different in the front legs like the males of other species of 

 the genus Telostylus. The front femora are provided below on 

 the apical half with two rows of short black spines, those of the 

 internal rows being distinctly longer. The basal joint of each 

 front tarsus is considerably swollen and spindle-shaped. The 

 femora of all the legs, and chiefly those of the intermediate 

 pair, are distinctly thickened. The genitalia are prolonged as a 

 cylindric protuberance, which is bent below, and in front of 

 this there is another yellow prominence. 



197. Nothybus triguttatus sp. nov. 



Very like the typical species, N. longithorax Rondani, from 

 Borneo, but differing in the wing pattern. 



Male. — Length of body, 7 millimeters ; of wing, 7. Head yel- 

 low. Occiput very much hollowed above, the eyes being prom- 

 inent on the sides; frons with a deep and broad excavation at 

 vertex behind the ocelli, and there with a striking velvety black 

 subquadrate spot ; the remainder of frons gently convex, strongly 

 glistening, with a broad velvety black spot on each side, in 

 contact with the eyes and of triangular shape, prolonged behind
