.Many niales and females from Balearica regulorutn rjibbencep.s. A remarkable 

 species with the males distinctly larger than the females, in this corresponding to ('. 

 macihntum of Nitzch which Giebel described as having the male larger than the 

 female mnch to Piaget's astonishment and unbehef. There is no doubt whatever of 

 the matter in this present African species. The extremely slender Lipeurus-Wke legs, 

 the long narrow Lipeuriform body, and the Lifeiirus-Wke markings make the species 

 a very interesting case of paralleUsm or convergence. There is an unusual amount of 

 Variation in the intensity and character of the markings, especially on the males. 



Male, length Zm, width O.o mm; long, slender, long legs, strong abdominal 

 markings, larger than female. Head, length O.'.ö mm., width O.s mm., narrow forehead 

 with a shallow rounding emargination just where palpi project beyond the margin; 

 front parabolic; ocular emarginations pronounced with eye distinctly emarginated ; 

 temples quadrangular and noticeably projecting and with strong brown spinous hairs, 

 3 longish, 2 shorter, rising, non-pustulated, from just within the lateral margins; 

 occipital margin strongly concave ; head translucent brown with fuliginous tinge, and 

 well-marked black occipital and antennal blotches not connected by bands. Pro thorax 

 as long as broad, Avith conspicuoiis, sharp-pointed lateral angles bearing four or fivc 

 short spinous hairs along postero-lateral margins ; color more smoky brown than head 

 with narrow blackish bands, one near each side. .Metathorax with the fused short 

 inesothoracic segment indicated by darker color and slight lateral emarginations; late- 

 ral margins and postero-lateral angles with spinous hairs; segment concolorous with 

 head and prothorax with darker lateral angles and posterior border. Legs unusually 

 long and slender, hindmost pair very long. Abdomen elongate, slender, but Httle 

 wider than head, and tapering posteriorly, two transverse rows of short brown spinous 

 hairs across each segment; shorter spinous hairs along lateral margins and longer 

 ones in postero-lateral angles; each segment with a narrow submarginal brown line 

 all around thus forming a quadrilateral figure ; rest of segment pale f uUginous brown 

 like thorax and head. In many specimens the chitinized genitalia with two distinct 

 strong posterior hooks show plainly. Posterior margin of last segment is narrowly but 

 flatly rounded with many short and fine, and several longer hairs. 



Female, body, length 2.« mm., width 0.53 mm., head, length 0.44 mm., width 

 0.58 mm.; thus being markedly smaller than the male; body all over strong opaque 

 brown except transverse pale sutural lines on the abdomen, and a narrow uncolored 

 median longitudinal line extending from abdominal segment 3 along the thoracic Seg- 

 ments and to middlc of head where it forks, the two branches going as straight diago- 

 nal lines to the anterior angle of each ocular emargination. Posterior margin of last 

 abdominal segment evenly rounded.
