described l>y Rev. 'Sir. Blackburn! Spocimens must have come to Los Angeles, and 

 if once numerous upon the coccids here there is ample time to destiny the same for 

 collections. 



Rhizobius ccecus Blackb.— Another of the common and beneficial insects. It was 

 found at Adelaide, South Australia, upon olive and feeding <>n Lecanium eassinice 

 Mask. Numerous at Paramatta, New South Wales, upon orange infested with red 

 scale as well as other coccids. and upon acacia infested with a Deaspid; at Gosford, 

 New South Wales, npon Gyncarpia laurijoliax on Clarence, Richmond, and Tweed 

 rivers upon various shrubs "and trees; at Brisbane upon orange infested with. J. 

 aitraiitii Mash., and at Toowoomha open same trees, as well ;is Acacia. The species 

 was sent in numbers to California. 



Rhizobius (hirlclltis Crotch) (?) — This insect has not yet been properly identified. 

 The Rev. Mr. Blackburn at one time sent me this name, but reported later that this 

 is not the insect. It ditfers from the description of this species. Always very nu- 

 merous at Paramatta, New South Wales, upon cilrus trees infested with A. aitraiitii 

 Mask., Mytilaspis Glover* Pack., and Chionaspia citri Comst. The beetle was repeat- 

 edly observed feeding upon this latter coccid, also met with in many other places 

 visited. Many specimens were sent by every steamer. The insect was not bred. 



Rhizobius pulcher Blackb. — A very common but small beetle, most numerous upon 

 acacia infested with a species of Diaspid, but also common on orange. It was met 

 with at Melbourne and northward to Brisbane; at Mount Victoria, New South 

 Wales, upon Lepiospermum infested with Eriococcus leptospermi Mask. Numerous 

 specimens were sent to California. 



Rhizobius au 8 trails Blackb. — One of the largest of the Rhizobiids. Found in South 

 Australia, Victoria, and New South Wales. The insect was bred from larva found 

 under bark of various Eucalyptus at Melbourne, feeding upon a species of Dactylo- 

 pius. The insect was not sent to California. These Rhizobiids so far named are from 

 the scant material retained. The list of the species sent here is by no means com- 

 plete, yet I did not consider it proper to waste a single insect when not necessary. 

 We want every one of these valuable beetles here to introduce them, and so far as 

 th<> name or life history is concerned, as long as we know the insect is beneficial, 

 and for this T am responsible, that is a secondary matter of very little importance 

 and can be studied by our grandchildren, for that matter. Among the alcoholic 

 specimens received from Mr. Coquillett there are two species of Rhizobius not in- 

 cluded here, as no specimens of the same were retained in Australia. Besides these, 

 several other species are yet to be worked up. 



Mi/In* pygmceits Blackb. — This insect was bred from a white, tufty larva found upon 

 orange al Parramatta, New South Wales. It was also collected in considerable num- 

 bers at Toowoomba, Queensland, upon the same trees. Became quite numerous at 

 Sydney during March, npon oleander and Piitoaporum infested with a specie- oi 

 Daclylopiua, upon which they appear to feed. Was also found at Mulgoa, New South 

 Wales, upon Eucalyptus. Many specimens were sent to California. 



Lipernes submridis Blackb. — A very small and common insect upon citrus trees 

 infested with Red Scale, Chionaspis citri and Mytilaspia Gloveri. Thelarva, with its 

 long, white, mealy, secreted appendages, was repeatedly bred. Also found at Gos- 

 ford, New South Wales, upon Ci/ncarpia: on the Richmond River and at Toowoomba 

 upon orange. Was always among the material sent to California. 



Gymnoscymnus 4-maculatus Blackb, — This insect was found at Gosford, New South 

 Wales, upon Gyncarpia laurifolia. Apparently a rare insect in localities visited, and 

 but a limited number could be obtained for California. 



CycloscymnuB minutns Blackb. — Found this beetle very numerous at Mount Victo- 

 ria, New South Wales, March 25, 1892, upon Leptoepermum lauigatum infested with 

 Eriocuccu* leptospermi Mask. The insect was sent to California. 



Cyrema nigellum Blackb. — The beetle was found at Adelaide. South Australia, in 

 company with Rkizubiua debilin Ulackb. ; and feeding with this upon Lecanium ca*si-
