(b) BLACKBUENi White is a closely allied Australian immi-

 c) KAHAVALu sp. nov.=B. iunotatus Kirkaldy, an endemic 

 Hawaiian form; (not Blackburn). 



13 B. mnotatus Blackburn. 



This, as mentioned above, is the B. blackburni of Swezey's 

 and my own writings. It is common on Saccharum ofjicinarum 

 and on Maniania grass {Cynodon dadylon), where it preys on 

 Leafhoppers and other small game. The ova and one nymphal 

 instar have been described and figured by Swezey (1905 Bull. 

 Ent. H. S. P.A., I 235, PL 17. fs. 2-4). The habits of B. 

 hlachbumi are probably similar. 



Fam. Reduviidae. 



The ova in this family, typically at least, are mostly pro- 

 vided with an ornamental cap of curious structure, which is 

 pushed off on emergence. The metamorphoses are partially 

 known in Harpador iracundus (*'') and (*^) Triatoma 

 scmguisuga (*^), BeduvHis personatus (^^), Endochus 

 cmgalensis (^^) and Arilus cristatus (^*), as well as an un- 

 known form described and figured from Brazil C*^). 



As in the other families, Dipterous parasites and Hymenop- 

 terous egg-parasites are known. 



As is indicated by the form of the labium, this family is 

 preeminently raptorial, but it has been stated that they are 

 sometimes phytophagous, or rather sap-sucking. (^^) 



14 Zelus peregrinus Kirkaldy. 



This, as elsewhere remarked, may be the inadequately 

 described Z. reimrdii Kolenati, from the Western United 

 States, but I do not feel convinced. 



It was first known in these Islands in 1897 and is now well
