NEW ZEALAND. 



On September 10, 1891, I reached Auckland, New Zealand, and four 

 weeks were spent here in search of predaceous insects. Here some 

 three hundred eoccineliids brought from California were turned loose 

 on apple trees full of Woolly Aphis [Schizoneura lanigera Hausm.). 

 The species were Hippqdamia convergens, Coccinetta califomica 7 and a 

 lew ft 8anguinea. Some three hundred Ghilocorus bivulnerus were 

 found dead in the box, while of the other only live dead insects were 

 found in the boxes. Two species of Chrysopa found feeding on Woolly 

 Aphis in California were also left here, these were in pupa state: and 

 some larva- of Raphidia. 



On my former and well-known hunting ground at Drury. near Auck- 

 land, various species of Scymnids were found breeding upon various 

 Gtenochitoii} many of these were collected, and S. acceptus Brown. 

 8. consors Brown, 8. villosns Brown, 8. flavihirtus Brown, 8. fagus 

 Brown, and S. picinus Brown were forwarded to Mr. Coquillett. The 

 last named species has a close resemblance to Rhizobius satellus Blackb., 

 the most numerous iuseets preying upon the Red Scale in Australia. A 

 search was made for Leis antipedum Muls., which had been found on 

 my former visit in such large numbers breeding upon Ctcnochiton viri- 

 dis Mask., but the insect had apparently not left its winter quarters 

 and but two specimens were found aud sent here. These coccids at 

 the time were all very small, having only recently hatched. Capt. Brown 

 was commissioned to search for this beetle during January, 1892, and 

 he also failed to find any of them. 



Our native Aspidiotus camellice Bois<d. (A. rapax Comst.) is one of the 

 most numerous around Wellington, where it does great damage to vari- 

 ous shrubs and trees, Inning as yet no natural enemies; the intro- 

 duction of such from here and Australia would soon alleviate its seri- 

 ousness. Our Chiloeorus bivulnerus .Muls. and some of the Scymnids 

 could be imported with advantage; yet much nearer, in Australia, far 

 belter enemies to this scale could be found in the various species of 

 Orcusand Rhizobius, which at the same time would also destroy all other 

 injurious coccids. The fungus Microcera rectispora Cooke could likely, 

 in the damp climate of Xew Zealand, be introduced upon this scale; 

 if so, with this alone it could almost be exterminated. Lecanium olea 

 Bern, was found quite abundant upon some trees in Dr. J. L. Camp- 

 bell's olive orchard at Lone Tree Hill, near Auckland. Internal para- 

 silo were here at work, but no predaceous insects were found preying 

 upon tin- n i. In one of the nurseries, upon a lot of young olive trees, the 

 closely related form L. cassinitB Mask, was found in large numbers with 

 its male form. A small bird, the so-called "white eye," is no doubt 

 pre\ in- upon t he black scales in New Zealand. I have myself observed 

 a swarm in a large oleander bush nt a churchyard in Auckland, and 



the gardner present told me that those birds frequently visit these
