First Stage Nymph. — Length 1.2 mm., width of head including 

 eyes 0.53 mm. Antennse about one third length of body, whitish ex- 

 cept first and second segments which are brown. Eyes prominent, 

 reddish, consisting of numerous distinct ommatidia. Body sparsely 

 hairy. Head, dorsal and lateral surface of thorax, dorsal and lateral 

 surfaces of abdomen brown. Median dorsal line beginning on head 

 extending through thorax broadening slightly on posterior parts of 

 thoracic segments, especially on the metathorax, where it forms a 

 white band between thorax and abdomen. Ventral surface light ex- 

 cept for broad median line on abdomen. Legs brown save coxa, 

 trochanter, basal portion of femur and apical portion of tibia which 

 are light. Rostrum white, extending to third pair of legs. 



Second Stage Nymph. — Length 1.8 mm., width of head including 

 eyes 0.8 mm. Antenna similar to those of preceding stage, slightly 

 darker. Eyes similar to those of preceding stage. Hairs on body 

 more pronounced. General color similar to that of preceding stage 

 but intensified. Broad median white stripe on dorsum of thorax 

 more pronounced. First abdominal segment and part of second ab- 

 dominal segment whitish. Small white patch in middle of third 

 abdominal segment. -Irregular whitish areas in center of abdominal 

 segments five, six and seven (latter white patches absent in some speci- 

 mens). Ventral surface like that of first stage (more pronounced in 

 some specimens, less in others). Legs quite hairy, brown except 

 coxa, trochanter, base of femur which are light. Rostrum extending 

 to second pair of legs. 



Third Stage Nymph. — Length 2.8 mm., width of head including 

 eyes i.i mm. Antennae about one fifth length of body. First and 

 second segments dark brown, remainder lighter. Eyes similar to 

 those of preceding stage. Dorsal surface dark brown, vertex of 

 head light. Broad, median, irregular dorsal white band on thorax, 

 extending into third abdominal segment in some specimens. Broad, 

 whitish patch in middle of sixth abdominal segment. (Some speci- 

 mens have, in addition, white patches on abdominal segments 5 and 7 

 and light spots on eighth abdominal segment.) Sides of meso- and 

 metathorax extending somewhat caudad. Legs similar to those of 

 preceding stage save articulation between femur and tibia, which is 

 somewhat lighter. Rostrum white, extending to beyond second pair 

 of legs. Ventral surface similar to that of first stage.
