Eleven Proterhinus (2 undetermined specieb). 



Note : — It is interesting to note that Pectinophora gossy- 

 piella attacks the seeds of Hibiscadelphus and is not contincd 

 (as jVIr. Busck has stated) to Gossypium. The Hibiscadelphus 

 are indigenous but exceedingly rare in our native forests, and 

 whilst a species of so-called "red cotton" (Kohia BocJcii) is 

 sparsely distributed in the forests of one sectioii of North 

 Kona, yet it is not the true cotton and Mr, Rock informs me 

 that on many visits to the region he has never noticed that 

 the "red cotton" bolls were ever atacked by ai-ything ap- 

 proaching Pectinophora. Mr. Busck however records the fact 

 that Lefroy has bred it from Hihiscus (an ally of Hibiscadel- 

 phus) in India. 



It w^as also interesting to note that one can breed out of 

 the stalks and seed pods of Hibiscadelphus so many insects of 

 various Orders, although it may be taken for granted that 

 some of these are more particularly attached to other tre*^* than 

 the particular one referred to. 



From the flower heads of Raillardia ciliolata collected at 

 Kilauea, October, 1917, a good series of the following insects 

 were bred: 



Diptera. — Tephritis sp., a good series of an undertermined 

 species. 



Homoptera. — Nesosydne raillardiae, one nymph. 



Parasitic Hymenoptera. — Eight Phanurus vulcanus Perk. 

 This is probably parasitic on the eggs of a bug {Nysiiis ?p.)i ^s 

 Mr. Swezey in examining the flower heads foand several 

 empty bug eggs similar to Nysius eggs previously found by 

 him in the flower heads of Bidens. 



Two Eulophids (Tetrastichiis sp.). These issued from 

 puparia of the Tephiitis as Mr. Swezey found, on later ex- 

 amination, tw^o puparia having exit holes made by some para- 

 site. Mr. Timberlake examined these Tetrastichiis specimens 

 and pronounced them as belonging to an undertermined s})ecies. 

 It is apparently a native insect, and the first nati^'-,' species of 

 the genus to be recorded in the Hawaiian Islands.
