far behind the middle ; female separated from male by the distinctly 

 shorter pronotum proper, which is considerably broader at the 

 constriction ; pronotal process with distinct bright rusty-yellow 

 (before and behind black) middle keel, a similarly coloured line on 

 each side of the marginal wrinkle, posterior border at middle narrow 

 and with a quite suffused dull reddish border ; shape of shoulder- 

 angle and colour of scutellum as in D. yeh ; colour of corium 

 rather dark, the black transverse band on costal border rather 

 narrow, the front and hind margins strongly obliquely truncated, 

 band-spot before the angle of corium punctured with black, not 

 extending so far inwards as in D. yeh, subtrapezoidal ; membrane 

 of the same length and ground-colour as in D. yeh, the apical half 

 darker, somewhat more sparingly sprinkled with greyish white or 

 suffused yellowish atoms ; of the five veins of the membrane the 

 second only has a strongly curved, narrow, otherwise little con- 

 spicuous yellowish streak, the third sometimes having a small 

 streak; from the typical yellow marginal spots of the abdomen 

 beneath extends the long produced front one, not quite to the 

 height of the front glandular spot in the fifth sternite ; anterior 

 femora on the upperside with very fine, scanty and short, scarcely 

 visible hairs ; colour of legs as in D. yeJi." (Breddin.)

" A narrow delicate species ; antennae slender, the third joint 

 especially thin, terminally not or very indistinctly clubbed, nearly 

 as long as the second joint, at least the first two joints of the 

 antennae paler than in D. nudipes, suffused pitchy brown, basal 

 joint sometimes rusty yellow, ring of the fourth joint honey - 

 yellow, not very sharply defined, somewhat broader than the pitchy 

 brown base of the joint ; pronotum very strongly constricted far 

 behind the middle, especially in 3, 'pronotum proprium' in S 

 distinctly longer than its width at the constriction, where it is 

 scarcely broader than the head and eyes, shoulders distinctly 

 angular, behind slightly concavely indented ; the pronotal process 

 in and behind the middle with a rather large transverse indistinct 

 dull red spot, resting on the hind margin, and the front border of 

 the pronotum, sometimes also two dots on the scutellum, of 

 similar reddish colour ; corium comparatively pale coloured, the 

 black transverse band on costal margin rather broad, front border 

 irregularly obliquely truncated, hind border rounded, the whitish 

 band-spot before the corium angle strongly compressed ; the 

 latter very finely and sparsely punctured with pitchy black, three- 

 cornered, with very pointed inner angles ; membrane remarkably
