and curiously pitted like the top of a thimble; the young larvae 

 irregularly breaking the summit as they work their way out. 

 Hiding among the eggs usually are to be found a great number 

 of small semitransparent mites, which crawl on to the baby 

 Thrips as soon as they are clear of the egg-shell; sometimes one 

 Thrip may have six or seven clustered together on its back, and 

 where the adult Thrips are confined among the infested eggs they 

 also become covered with the mites. The adult Thrips often 

 stand guard over the egg-masses, evidently with the idea of pro- 

 tecting them. In one case in particular, a male remained all day 

 over the eggs; when touched, it crawled round to the under 

 surface of the leaf, but returned as soon as the glass lid was 

 replaced . 



Larva, on emerging from the egg, about 1 line in length. 

 General colour semitransparent, antennae distinctly banded; eyes, 

 sides of thorax and abdomen edged with bright red, with a slender 

 dorsal stripe of the same colour down the centre of abdomen, 

 merging together at the fuscous tubular segments at apex. 

 Irregularly covered with long, scattered fine hairs. Head broad, 

 antennae thickened, eyes small, thorax long, abdomen short. 



Larva: second stage. — Head more rounded, widest behind; 

 antennae long, eyes black, the rest semitransparent to dull white, 

 marked with bright red on outer margin from behind the eyes to 

 the base of anal segments, with a broad dorsal stripe commencing 

 behind the pronotum, and merging into the side stripes at apex; 

 transverse rows of spots on dorsal surface of thoracic and abdomi- 

 nal segments, and two apical tubular segments black. 



Larva: third stage. — Head much larger, arcuate in front; 

 antennse long, slender and showing swelling at the apices of 3rd, 

 4th and 5th segments; eyes projecting. General colour fuscous, 

 with apical portion of thorax and centre of abdomen semitrans- 

 parent, with red markings showing, but confined to apical portion 

 of abdomen; thorax and base of abdomen elongate-oval, tapering 

 to the tip to a slender cylindrical tail, which consists of two 

 tubular segments nearly as long as the thorax and rest of abdomen 

 combined, fringed with scattered long hairs.
