of the many bred while in Australia, and comes closest to that of Scymnus notcsccus 

 Blackb., which is also much flattened and having a row of lateral spines dissimilar 

 to any Scyinnid larva that I am acquainted with. Jn these the Lateral spines are 

 longer and each bearing again numerous spinules and bristles. They were found 

 feeding on a small coccid covered with a white felted matter, apparently a Fiorina. 

 The same insect was also found in the Blue Mountains upon Leptospermum and 

 here feeding on Eriococcua leptospermi Mask. 



Another form of this beetle, which Rev. Mr. Blackburn named u var. varipes" was 

 found at Gosford, New South Wales, upon Cyncarpia laurifolia infested with Chion- 

 aspis i )((/( ni<i Mask., J npidiot us cyncarpice Mask., and on Dactylopid. This same va- 

 riety had also been found at Toowoomba, Queensland, upon Eugenia sp., on which 

 the same Chionapsis was present, and at this place also upon orange infested with 

 Red and Black Scales. Both these varieties were sent to Los Angeles with the request 

 to liberate the same in orchard with Black and Red Scales. A number of both forms 

 were sent to Hon. Ellwood Cooper. These as well as all other material sent reached 

 him in May. and were liberated in excellent condition upon the Black Scale on olive. 

 I could not yet see the insect on September 3, 1892, at his place. Some two hundred 

 specimens of S. koebelei brought home were liberated upon orange infested with 

 Black Scale at Hay ward's during August. 



ScymnusnotesceusEl&cJsb. — This beetle, although not very common, appears to be well 

 distributed, as it was found in South Australia, Victoria, New South Wales, and 

 Queensland. It was met with most numerous upon orange, but also upon Acacia, 

 myrtle, etc., at Toowoomba ; upon Casuarina at Whitton, New South Wales, and at 

 Adelaide it was found in large numbers and in all stages feeding upon Aphids on 

 corn. The beetle was repeatedly sent to California. 



Scymnus flarifrons Blackb. — One of the smallest and most common of all the Scyni- 

 nids found. Its food appears to be various, and it may be expected to feed upon most 

 of ourscales, and positively Lecanidiua?. Found the same at Toowoomba, Queensland, 

 upon orange infested with Red and Black Scales; upon Acacia infested with an 

 Aspidiotus, and on A. eucalypti Mask., upon eucalyptus; at Gosford, New South 

 Wales, upon Cyncarpia laurifolia infested with Aspidiotus cyncarpice Mask., aud 

 Chionaspi* eugeniae Mask., near Sydney and at Mount Victoria, upon Leptospermum 

 lawigatum F. v. Mueller, feeding here in very large numbers — both in larva and 

 imago state— upon Eriococcus leptospermi Mask. It was always numerous at Parra- 

 matta. and from a lot of larvae and pupa? saved from a small bush infested with 

 Lecanium cassinia Mask, parasites were bred from the larva? and most of the pupa? 

 were found infested with a small chalcid. A form closely related to this, and named 

 by Rev. Blackburn Scymnus tencbricosusBohem., was found with the foregoing upon 

 Eriococus leptospermi Mask., as well as upon Bhizococcus araucaricc Mask. A third 

 form found upon Eriococcus Tepperi Mask., upon one of the stringy bark eucalypti at 

 Mulgoa, New South Wales, is also placed here. This was very numerous, and its 

 larva — of which unfortunately no specimens were saved — were present by the hun- 

 dreds. They resemble those of S. flarifrons Blackb., but are about twice its size, as 

 i- also the mature insect. Some twenty-five of these larva- kept in confinement at 

 Sydney began to pupate on December 8, 1891, becoming partly covered with white 

 powery dust as they began to shrink. On return to Sydney. December 19, 1891, all 

 the beetles had already hatched out. The same form was also found at Mount Vic- 

 toria and feeding upon Eriococcus hptospcrmi Mask. Large numbers of the beetles 

 were sent to California. 



Scymnus syditeyensis Blackb.— This beetle was found at Parramatta, New South 

 Wales, upon orange with both Red and Black Scales, and upon a small shrub infested 

 with Lecanium c<issi„i,r Mask.; at Mulgoa, New South Wales, December 4, 1891, 

 upon Acacia, Eucalyptus, Leptospeimum, and orange, and at the same place, upon a 

 former visit, on peach trees infested with Aphids. It was found at Toowoomba, 

 November 12, 1891, and again at the same place in large numbers April 6-11, 1892,
