slight hinge. When the cocoons are affixed end to end in 

 the heap, the lids appear to be always formed and pushed 

 off at the free ends.] 



Nos. 7 and 8. — From the pupse of the case moth Ardio- 

 stercs moretonclla, Walk., the larvas of which live in the 

 nests of small black tree ants. The Lepidopterous larvae 

 never leave these nests ; but in order to pupate they 

 approach closely to the entrances, when they are, no doubt, 

 victimised. 



[No. 7 is borne by the following undated set of speci- 

 mens : a Lepidopterous case from which the empty pupal 

 skin of a moth projects, so that this particular specimen 

 was not parasitised ; 2 $ Chalcidid/u described by Col. 

 Bingham as Stomatoceras fasciati'pennis (Appendix, p. 128) ; 

 4 ants identified by Prof Auguste Forel as Cremastogaster 

 Iceviceps, Smith. 



No. 8 is borne by a set of specimens dated June 5, 1902 : 

 2 flattened dumb-bell-shaped Lepidopterous cocoons the 

 larger of which has been pierced by an emerging parasite, 

 the other very small ; 1 Chalcidid considered by Col. 

 Bingham to be probably a species of Halticella, but too 

 fragile to bear removal from the card for examination ; 2 

 Cremastogaster Imvicciis, Smith, ^.] 



No. 9. — These bright little Chalcidid?e I have bred fre- 

 quently from the pupa^ of the fine long-jawed ant 

 Odontomaclius sp., several sometimes coming from the one 

 cocoon. 



[No. 9 is borne by 2 $ and 1 $ Chalcididse described by 

 Col. Bingham as RMinpallus ajfinis (Appendix, p. 129). 

 They are dated July 30, 1902. Another set of specimens, 

 without number, but dated March 16, 1902, contains 1 ^ 

 and 1 ^ of the same species of Chalcidid, 1 worker ant 

 identified by Prof. Forel as Odontomaclius ruficcps, Sm., 

 subsp. coriarius, Mayr., ^, and 1 ant cocoon. A third un- 

 numbered set, dated Oct. 1902, contains 1 ^ and 2 $ of the 

 Chalcidids, and 1 worker of the above-named species of 

 ant.] 



No. 10 is a great rarity and the only specimen I have 

 bred from several lots of pupai of a large ant, Gamponotus sp. 

 From one lot I obtained some large bright pink mites, but 

 I lost these in a great cyclone on March 9, 1903. 



[No. 10 is borne by the $ of a beautiful and remarkable 

 Chalcidid described by Col. Bingham as ScJdzasjridia doddi 

 (Appendix, p. 130). It is dated" Jan. 1903.J
