36 Mr. H. Druce on new Species of 
Horatocera niponica, sp. 1. 
g. Elongata, nigra, vix nitida; thorace rufo in medio canaliculato, 
utrinque foveolato ; elytris basi anguste obscuro-brunneis. 
L, 12-14 mill. 
©. Tota nigra; antennis brevibus. 
ely mall: 
Elongate, black, somewhat shining; the head, surface 
uneven, rather coarsely and rather rugosely punctate, with a 
median concavity behind the antenne ; the antenna, first joint 
rather long, somewhat bent, surface punctulate, second very 
short, third and those following to the tenth nearly coequal, 
but the appendages to the third and fourth are distinctly 
shorter than those of the others, eleventh joint is longer than 
the first, second, and third together, and has no appendage; 
the thorax red, with a tawny pubescence, widest posteriorly, 
narrowest anteriorly, sinuate laterally near the middle, with 
a longitudinal median channel and a deep fovea on each side 
of it rather behind the middle, posterior margin very narrowly 
edged with black; the scutellum nearly as long again as 
broad, with the edges raised posteriorly, irregularly punctured ; 
the elytra black, with their bases obscurely brown, coarsely 
sculptured, punctate, with the interstices of the punctures 
raised, vaguely costate, with the sutural and _ epipleural 
margins a little elevated; the legs black, with the claws in 
both sexes reddish ; anterior tibie not crenulate nor denticu- 
late*. ‘The female is wholly black, with shorter antenna, a 
wider head, with a transverse ridge between the antenne and 
a bilobed depression between the eyes. There is a variety of 
the male in which the head and elytra are reddish brown; but 
in no case is the colour so bright as that of the thorax. 
Hab, Fukushima, Nara, and Usui-togé. Nine males and 
one female.

Robinsonia sabata, sp. n. 
Primaries and secondaries pure white : primaries, the costal 
margin edged with pale brown from the base nearly to the 
* This character is noticed because Homeorhipis, Fairm., 1887, is a 
genus in which the species have the tibie crenulate, and Callirrhipis 
Pascoet, Waterh., has the tibie denticulate. “
