Bhizohius satcllus Black!). — This Lad always been the most numerous insect ».>>on 

 citrus trees at Paramatta, heir preying upon the Red Scale. I look for its increa. .> 

 in this country with great interest. Upon my hunting ground I had three wild 

 lemon trees bordering a forest, and somewhat apart from the orchard, badly affected 

 with A. auranti Mask., so much so that any fruit-grower in California would have 

 given them up for lost and would speedily have applied his "wash" or " fumigation ". 

 as a last hope. Here this beetle, h'hi:ohiiis, stepped in and in such numbers that the 

 larva- could he found by the thousands. At the end of about six weeks the work 

 was completed and the trees left completely free of scales. With the exception of 

 losing a tew leaves the trees did not sulferin the least. Both the Orcus, O. chalybeus, 

 and (). australasia, as well as numerous other species, were also present, hut not in 

 such large numbers. The insect was met with at all places visited in New South 

 Wales and Queensland, and with us will no doubt feed upon many of the Aspidiotus 

 and probably various other coccids. Some six to eight thousand specimens of this 

 beetle were collected and sent here, most of these to Los Angeles. No parasites were 

 observed preying upon the larva- of this insect, yet it is more than likely that this 

 also has its enemies. I found the larva- still feeding on my return from Fiji, July 

 4-6, at Paramatta, although midwinter, when many of the other Ladybirds were 

 hibernating. 



Bhizobiu8 fugax Blackb. — Another of the larger species found in few specimens at 

 Melbourne and quite numerous at Whittou, New South Wales, upon Casuarina 

 infested with an Acanthococcid. The insect was sent to Los Angeles. 



Bhizohius dorsdlis Blackb. — Another common and valuable insect especially for 

 the Black Scale, and I look for its appearance in California at Hon. Ellwood Cooper's 

 place, where specimens were liberated. This was met with in New South Wales, 

 near Sydney, upon Leptospcrmum Icevigatum and feeding upon Eriococcm leptospermi 

 Mask., on Bhizococcus araucarias Mask., and black scale; at Gosford upon Cyncarpia 

 laurifolia, upon which tree likely another coccid may be present than those ob- 

 served. Larvae found at Mount Victoria upon Leptospcrmum differ from those of 

 J?, ventralis and B. dcuilis, with which they were found, by their lighter and more 

 reddish color. The insect was repeatedly sent to Los Angeles, and in one consign- 

 ment to Elwood. 



Bhizohius cyancus Blackb. — Another new form of this valuable beetle, which may 

 become of value if introduced. The insect was found at Mulgoa, New South Wales, 

 upon Eucalyptus infested with Eriococcua Tepperi Mask, A much larger species was 

 seen at the same place, which may have been B. xanihuma Muls.. which is reported 

 from Victoria. 



Bhizohius specuVxfcr Blackb. — This insect was always found in numbers at Para- 

 matta, New South Wales, upon citrus trees infested with coccids. The mature 

 beetle was observed to feed upon the males of Chiona8pia eitri Comstock. Also 

 numerous at Toowoomba, Queensland, upon orange and on Eugenia upon Chionaspia 

 euyenlic Mask. The beetle was sent to California in numbers. 



L'hizobius toowoomlxe Blackb. — Was found in Victoria, New South Wales, and 

 Queensland; most numerous at the latter place. The beetle was bred from larva 

 found feeding upon Asj)idiotus ncrii Bouche, at Melbourne. It is always common 

 upon orange infested with the red scale. The mature insect was sent to California 

 in numbers, and may be expected here, as do most of these forms, to feed upon most 

 any coccid. Mr. Tryon in "Insects and Fungus Tests." p. 131, mentions and de- 

 scribes a lihizohius feeding upon the red scale at Toowoomba, the description agree- 

 ing with this species, which is one of the most numerous in that locality. 



li'hizohius aurantii Blackb. — A form found at Toowoomba upon Red Scale affected 



trees and without doubt feeding upon this as well as other coccids. As previously 



d, no insect was ever killed simply for specimens, only forms that positively 



Looked strango and of which I wanted bo gel the life history. This also appeared 



to be one of the forms of which only a single specimen was saved, and which wafl
