the beetles issued, then placed the latter on the ash tree above men- 

 tioned. Besides these, there was also a package of twigs on which were 

 numerous specimens of Lecanium olece infested with a fungus; these I 

 placed on an oleander bush thickly infested with the above -mentioned 

 Lecanium. The package also contained eight large black Scymnids, 

 which fed sparingly upon Lecanium olece, and I therefore had a tent- 

 erected over an orange tree thickly infested with these scales, and 

 placed the Scymnids in this tent. This tree was placed at my disposal 

 by Judge E. Silent, of this city. 



I received the next consignment on the 20th day of February, 1892. 

 It was not accompanied by any letter. The entire package was com- 

 pletely soaked with water when it reached me, and several of the boxes 

 were broken open. This consignment contained eight living adults of 

 Orcus chalybeus, which I liberated in the same orange grove where I 

 had placed those of the previous sending ; twenty-three Scymnids, Avhich 

 I placed on the orange tree infested with Aspidiotus aurantii, under the 

 tent, and thirty adults of Orcus bilunulatus, which I placed on the 

 orange tree infested with Lecanium olece under the tent at Judge Silent's. 



The next package of insects reached me on the 21st of March, 1892, 

 and was accompanied by the following letter, written at Sydney, New 

 South Wales, February 22, 1892: 



I have your letter of December 30. Sent a lot more of Orcus and a small Scymnid 

 on Red Scale; this latter is as good as Orcus in destroying these scales. 



In box with Eriococcus you will find some Scymnids feeding on Black Scales, also 

 their larvae, larva' of Thalpochares and of a Pyralid ( ?). This latter you bad before. 

 They may feed on Lecanium. Breed all these in confinement, and not get box near 

 Eucalyptus. A whole box full of Lecanium with internal parasites. You had better 

 not place them on trees, but at a distance from them, as, if necessary, in case the 

 Scales should establish tbemselves, they could be promptly destroyed. The same 

 may be said of the Eriococcus, which, although only feeding on Eucalyptus, is a bad 

 thing on these trees. 



Await Zeis antipodum and rear on Lecanium hesperidum. — A. Koebele. 



This package did not contain a single living insect when I received 

 it. Among the dead insects was a ladybird larva which I recognized 

 as belonging to Scymnus lophanthce Blaisdell, a species which had evi- 

 dently been imported into this State from Australia several years ago, 

 and upon procuring specimens of the larvae of this ladybird from orange 

 trees in this city I found that the two forms were identical. The 

 package also contained dead specimens of a ladybird which agree in 

 every particular with specimens of the above-named Scymnus contained 

 in my collection and which were captured in this city several years 

 ago. Specimens of both were submitted to Dr. Eiley in order to settle 

 this question definitely, and he writes me that the two forms, the one 

 received from Australia and the other collected in this city, are indis- 

 tinguishable, and that both belong to the species recently described by 

 Dr. Blaisdell as Scymnus lophanthm (see u JEntomo logical News," vol. in, 

 p. 51). I gave a description of the larva and pupa of this ladybird in
