clxx FAUNA HAWAIIENSIS 



elevation of about 1800 ft. in the mountains and occurs in gardens in Honolulu. The 

 caterpillar is sometimes parasitized by the Braconid, Rlicrodus hawaiicola, and I believe 

 also by a now very abundant species of Chalcididae {^Hockeria) of recent introduction 

 and not included in the systematic portion of this work. Philodoria is an important 

 endemic genus with seven species described. The mines are very conspicuous in the 

 leaves of the urticaceous Pipturit,s, many examples of P. niicropetala sometimes being 

 bred from a single large leaf P. splendida is attached to Metrosiderus (Myrtaceae). In 

 wet boggy forests we have noticed mines in quite different plants, amongst these being 

 Myrsine, but Piptnriis certainly is the food-plant of more than one species. Of Oraci- 

 laria epibathra the habits are not known, but G. inarginestrigata is a very common 

 insect, the larval mines in the leaves of Sida being very conspicuous. Besides this 

 malvaceous plant it also mines the solanaceous Datura siramonium and some others. 

 Other species of this genus are known, but have not been described in this work. 

 Both Philodoria and Gracilaria are frequently parasitized by Omphale meial/iai-s, and 

 other minute Eulophidae. The four species of Bedellia are of some interest. One 

 has been referred to the European sommilenlella, and one to the American minor. 

 The latter is very common, the larvae mining the leaves of Iponioea of various species. 

 The former, however, as well as the two species described as new, seems to occur in 

 localities quite beyond the range of any Convolvulaceae, and to- have some different 

 food-plant. Setomoipha dryas is an introduced insect, and Acrolepia aiLreonigrella may 

 come under the same category. The three species of Monopis and Tinea are of course 

 importations and without interest, while the unique insect, for which the genus Para- 

 phasis was made, is of uncertain status. 



Review of Neuroptera. 



One hundred and sixteen species of Neuroptera (s.l.) have been enumerated in the 

 systematic portion of this book, and these represent but six families of the Order. If 

 one excludes the Psocidae, of which very many species have been imported with plants 

 from other countries (these species, however, not having been enumerated in this work), 

 the Neuroptera are singularly free from artificially imported species, more so, indeed, 

 than any other Order. There are, however, several species, which, we can be sure, are 

 natural immigrants, viz. the three dragon-flies of very powerful flight, Pantala flavescens, 

 Tramea laceraia, and Anax Junius, all species of wide range and inhabiting the 

 American continent. A small white ant\ destructive to houses and woodwork all over 

 the islands on the lowlands, has been established for many years, having, no doubt, been 

 brought in with lumber. A few are of doubtful status, the Embiid, Oligotoma, and 

 the Hemerobiid, Megalomus hospes, being probably either natural immigrants or 

 endemic, while the ubiquitous Chrysopa microphya is more likely an importation. In 



' One if not two other species of Termites have more recently been introduced into Honolulu.
