X. — ANTHERAEA BRUNNEA, NOV. SPEC. 

 BY R. VAN EECKE. (WITH PLATE H, fig. 3). 



Near to Antheraea imperator Watson (Notes Leyd. Mus., Yol. XXXV, 

 p. 184, 1912/13) from Java, but the general colour is dark reddish 

 brown with brownish orange. Antennae brown, pectinated ; the first 

 antennal joints quadripectinated, the last eight antennal joints very 

 shortly bipectinated. Head small, with brownish red hairy front and very 

 small palpi. Collar and prothorax yellowish white; thorax and abdomen 

 dark reddish brown. Legs on the outerside with long hairs, which con- 

 ceal the spurs on tibiae and tarsi. 



Apex of fore-wing hardly falcate, more straight. Costa yellowish 

 grayish white, except a patch before the large whitish costal spot near 

 to the apex. The outer-corner of the apex redbrown. The outer-margin 

 bends a little inwards to vein 5 with a rounded distal angle; the hind- 

 margin nearly straight. On the discocellularis a nearly round ocellus 

 with a black outline and a dark orange-brown inner part, in which a 

 very narrow oblong small vitreaos spot. A distinct submarginal line, 

 commencing at the whitish apical spot and continued obliquely to the 

 hindmargin. This line is white at the innerside, then brownish and more 

 yellowish at the outerside, straight, a little curved between the nervules 

 4, 5 and 6, not parallel with the outer-margin of the fore-wing. Between 

 the ocellus and the submarginal line an orange-brown band is faintly 

 indicated from costa to innermargin. Near to base of cell a trace of a 

 whitish antemedial line with some black at the outerside. The rest of 

 the fore-wing dark reddish brown. 



Hind-wing triangular, with rounded angles; the outer-margin a little 

 protruding on nervule 3. The ocellus on the discocellularis larger than 

 that of the fore-wing with a black outline, a very narrow grayish white 

 line at the side of the wing-base, followed by a black spot, between the 

 narrow fenestra and the grayish white line. The rest of the ocellus dark 

 brownish red. A bluish grayish white line extending faintly from anal 

 margin, firstly straight, then broader round the ocellus and after a breaking 

 off running round the outside of ocellus and continued as a straight line 

 to the anal margin. A second more yellowish line is running at the 

 outer side, parallel with and very near to the whitish line. The rest of 

 the hind-wing dark reddish brown. 



Below the wings are more grayish, caused by a large number of 

 grayish white scales and hairs among the redbrown scales. On the fore-
