624 Characteristics of the Insect-Fauna 



darkest ; labium dark-brown ; ocelli five in number, four 

 in a rather open curve, convex in front, one below, sepa- 

 rated considerably from the upper three, which are crowded, 

 and are directly behind it at a little greater distance; all 

 black, except the uppermost, which is reddish brown ; the 

 lowest of the upper three larger than any of the others, 

 which are equal. The segments behind the abdomen 

 have five longitudinal bands, a dorsal, subdorsal, and lat- 

 eral ; a narrow black dorsal band, enclosing little longitu- 

 dinal rather pale green spots or dashes on the apical half 

 of each segment, those of the thoracic segments uniting 

 to form a narrow line ; this band tapers at each end, and 

 is about .015 inch in extreme breadth ; the subdorsal is a 

 very narrow interrupted black band, narrower than the 

 dorsal, the dashes of which it is composed being situated 

 principally upon the anterior portions of segments, and 

 arranged a little obliquely, the anterior extremities being 

 directed downwards ; the dorsal and subdorsal are sepa- 

 rated by a space which is .035 inch in breadth, pale 

 yellowish green, tinged with faint reddish brown at the 

 apical half of each segment ; the lateral band is separated 

 from the subdorsal by a similar distance, and is itself of 

 the same width ; it is dark green, edged at its upper bor- 

 der with black, which is dillused downwards slightly at 

 the base and apex of each segment, especially on the ab- 

 dominal ones ; the space between subdorsal and lateral 

 bands is like that between dorsal and subdorsal, except in 

 being considerably tinged with reddish brown ; below the 

 lateral band the body is grass-green, with a flush of rose- 

 ate in it, the spiracles being black ; the under surface and 

 prop-legs are uniform grass-green ; legs dusky. The 

 whole body is covered with very short delicate reddish 

 hairs arising from minute pale warts ; the body is cylin- 

 drical, thickest at the apodal segments, narrowed gradually 

 behind, a little more rapidly in front ; head rather small ;
