NTCTEMERA ANNULATA OF NEW ZEALAND. 143 



ments 3, 4, 5, 6. Segments 7, 8 have one subventral seta each. Seg- 

 ment 9 has the position of the trapezoidal tubercles reversed ; one 

 subventral seta Segment 10 viewed laterally has two dorsal tubercles 

 and two subdorsal, with one seta each ; theie are three setae in the 

 region of base of claspers. Tlie abdominal feet and claspers are cone- 

 shaped at the base, sticking out of which a pedicel or stalk with a 

 broad end has a few terminal hooks. Ventially the abdominal feet 

 have a seta on the inner side, and corresponding setse are on the 

 footless segments. 



Five days old (first skin full fed). — Length just prior to ecdysis 

 j^ inch ; larva is much distended, and has lost the lumpy appearance. 

 Head : dark brown. Prothorax : dorsal plate very dark brown, seg- 

 mental area white. Meso-thorax : mottled red longitudinally between 

 dorsal and subdorsal tubercles. Post-thorax : the red extends above 

 dorsal and below subdorsal tubercles ; segmental area yellow. Abdo- 

 minal segments are yellowish white, with reddish colour enclosing the 

 post-trapezoidal and supra-spiracular tubercles, connected dorsally 

 posterior leaving anterior trapezoidals on a median patch of yellow 

 colour ; transverse mottling connects the supra-spiracular and sub- 

 spiracular tubercles. 



Eight days old (second skin). — Length about ^^ inch. Similar 

 marking to prior to ecdysis. Head shining black. Pro- and meso- 

 thorax white. Abdominal segments are yellow : between the tubercles 

 transversely the colour is brown connected dorsally. Spiracles brown. 

 Setse shining brown ; all segments appear to be the same size ; larva 

 robust. Head : all hairs are smooth. Prothorax : scutellum at eithe 

 side has an anterior series of five setas and two posterior setae. A 

 small subdorsal tubercle bears two hairs, large lateral tubercle about 

 six setse ; posterior to this is the spiracle ; below the spiracle a large 

 tubercle bears about nine setge. Meso-thorax : large dorsal tubercles, 

 one at either side of mid- dorsal hne, bear about fourteen setae ; a small 

 subdorsal tubercle has one hair ; large mid-lateral tubercle bears nine 

 setse ; a large tubercle above legs bears about nine setse. Post-thorax 

 as meso-thorax. All the thoracic legs have spinulose setae at the 

 joints. Abdomen : the anterior trapezoidal tubercles are minute, with 

 a single spinulose seta each ; post-trapezoidal tubercles are mid-dorsal 

 at either side with aix setae each ; supra-spiracular tubercle (sub- 

 dorsal) are very close to post-trapezoidals, but moved a little forward ; 

 these have seven setae. The spiracle is anterior below the supra- 

 spiracular tubercle ; two large tubercles, one below the other under 

 the spiracle, bear eight setae each. It is difficult to make sure of the 

 tubercles, owing to the numerous setae. Segments 1, 2, 7, 8 have a 

 small subventral tubercle with four setae (short). Segments 3, 4, 5, 

 6 have corresponding tubercle at base of abdominal feet, which are 

 also covered with numerous short spinulose sets. Segment 9 has a 

 very large subdorsal tubercle with about seventeen setse ; lateral 

 tubercle with about eight setae, and subventral tubercle with four setse. 

 The ventral tubercles have about five setae each, and the abdominal 

 feet have numerous spinulose setae all over inner side. Terminal 

 hooks are only on inner side of the abdominal feet. The whole larva- 

 skin is covered with fine hairs.
