404 ARTHUR DENDY. 



The inner jaw-blade (fig. 35) has one large tooth and about 

 five small ones. The outer blade (fig. 34) has no accessory 

 tooth. 



The ovipositor of the female resembles that of the other 

 species of the genus, and is conspicuous between the legs of 

 the last pair as a subcylindrical protuberance of a pale 

 yello^\f colour, bearing the genital aperture as a longitudinal 

 slit at its apex. There are no crural gland papilla? in the 

 female. In the male the genital aperture occupies the 

 usual position, and there are indications of a pair of white 

 papillge (perhaps fused together) just behind it on the short 

 anal cone. Crural gland papilla? may occur on the legs of 

 the last nine pairs. 



The general coloration of the dorsal surface to the naked, 

 eye appears dark, sometimes almost black, speckled with pale 

 orange or yellow. Closer examination of typical specimens 

 shows a very characteristic pattern, which may be described 

 in general terms as " chequered." The general ground colour 

 is dark indigo-blue,^ often almost black, and this is chequered 

 by more or less regularly arranged patches of pale dull 

 orange or yellow in transverse and longitudinal rows. 

 Though irregular, the patches may generally be described as 

 roughly rectangular in outline, forming a kind of chessboard 

 pattern with the dark ground colour (fig. 3). A longitudinal 

 row of the lighter patches runs down the middle ; these are 

 small, and each is divided longitudinally in the middle line by 

 a narrow dark band, which in turn is interrupted by the very 

 narrow, unpigmented, mid-dorsal groove, visible under the 

 microscope. The dark band widens out between the successive 

 light patches of the row, forming alternating dark patches. 

 Then on each side comes a row of larger light patches 

 alternating with those of the middle row. Then another row 

 of light patches alternating with the last, and lying in the 

 same transverse -rows as the median light patches, over the 

 legs. In addition to these patches individual light-coloured 



^ May be greenish indigo in preserved specimens.
