segments, line on front of head, tubercles, bases of legs, dorsal sur- 

 face of abdomen and bands extending anteriorly near sides of thorax, 

 which are brownish. Tubercles as noted before in first stage, but more 

 pronounced and in addition, single pointed tubercles on sides of pro- 

 and mesothorax, on sides of 4th, 5th, 6th, /th, 8th, gth abdominal seg- 

 ments and two minute tubercles on face just below vertex. Rostrum 

 extending to last pair of legs. Eyes similar to those of first nymphal 

 stage. Antennae three-fifths length of body. 



3rd Nymphal Stage. Length exclusive of tubercles 0.8 mm. Similar 

 to second stage except that coloring and structure are more pro- 

 nounced. Body elliptical, color white except tips of ultimate and pen- 

 ultimate antennal segments, line on front of head, bases of legs, dor- 

 sal surface of abdomen, posterior lateral sides of thorax, some of pos- 

 terior and lateral margins of head and tubercles which are brownish. 

 Dorsal surface of abdomen and tubercles darker brown than re- 

 mainder. Tubercles similar to preceding stage but more pronounced 

 and in addition two white median dorsal tubercles on pro- and meso- 

 thorax. Tubercles on sides of mesothorax rest on basal lobes. Eyes 

 similar to preceding stage. Antennae tending toward yellowish white, 

 three-fifths length of body. Rostrum extending to last pair of legs. 



4th Nymphal Stage. Length exclusive of tubercles 1.2 mm. Body 

 broadly elliptical. Color white except tips of ultimate and penultimate 

 antennal segments, line on front of head, bases of legs, most of dorsal 

 surface of abdomen, posterior two-thirds of thorax, portions of lateral 

 and posterior margins of head, outer sides of basal segments of an- 

 tennae, outer surfaces of tarsi, rostrum and tubercles, which are brown. 

 Antennae yellowish brown. Median dorsal tubercles on prothorax 

 white except at tips. Tubercles similar to those of third stage but 

 more pronounced. Lobes of mesothorax more pronounced, covering 

 those of metathorax. Antennae about three-fifths length of body. 

 Rostrum extending to third pair of legs. Eyes consisting of numerous 

 ommatidia. 



$th Nymphal Stage. Length exclusive of tubercles 1.8 mm. Body 

 oval. Color: antennae light yellowish brown; line on front of 

 head and portions of lateral and posterior margins of head, posterior 

 margins of pro-thorax, most of meso- and metathorax, basal three- 

 fourths of abdomen, base and tips of wing pads, tubercles, outer sur- 

 face of basal antennal segments, tips of ultimate and penultimate an- 

 tennal segments, bases of legs, bases of tarsi, outer surface of rostrum, 

 brown ; remainder white in part tinged with brown. Tubercles very 

 pronounced, acuminate. Wing-pads extending to 5th abdominal seg- 

 ment. Eyes more prominent, consisting of numerous reddish omma- 

 tidia. Median dorsal elevation on prothorax. Rostrum extending be- 

 tween 2nd and 3rd pair of legs. Antennae almost as long as the body.
