hrevipennis and several other species, Acalles humeralls, Pa- 

 randrita aeneiis, and several species of Oodemas, amoni^ the 

 Coleoptera; Anomaloclirysa soror, an Aphis lion; Odynerus 

 camellnus, nivicola, erythrostades, Nesoprosupis difficilis, Dei- 

 nomimesa haleakalae, among Acnleates, and one Eapelmua, one 

 Pleuroneuropliion, Enicospilus molokaiensis and Scleroderma 

 polynesiale, among- the Parasitica ; and of Homoptcra several 

 species of Jassids and several of OUarus and 4 new species of 

 Delphacids which will be described later on. Unfortunately 

 among the latter the males were sparse in individuals only two 

 or more of the species having been taken in series of both sexes 

 with nymphs. So far as it was possible all food plants of the 

 species were recorded for convenience of others who may desire 

 to explore this interesting region. 



A day or two later a short visit was made to the new Hama- 

 kna ditch trail (Lnpe) bnt the road to this region was almost 

 impassable and much time was lost in getting there. Tiie forest 

 here is at an elevation of approximately 1200 feet and is not 

 nearly so interesting as that near Olinda. The indigenous veg- 

 etation is much more sparsely distributed because of destruction 

 caused by stock ; and foreign weeds and grasses have crept in 

 and are destroying much of the indigenous growth. It rained 

 almost constantly on the day of our visit and in consequence 

 there was not much to record from this region other than one 

 new species of Nesosydne and several Jassids amongst the 

 Homoptera and Odynoiis ecosfntus, cconelijius and instabdis 

 among the Aculeates. 



A morning was spent on the "Wailuku Commons but the 

 indigenous vegetation on these sand hills has become very 

 sparse due to continual pasturing of cattle and use of large 

 portions of the locality in recent years for the growth of sugar 

 cane and other purposes. On Coreopsis mauiensis a large series 

 of what is apparently a new Nesosydne was taken but Aculeate 

 Hymenoptera, particularly the low land species of Odynerus 

 and Nesoprosopis which were formerly quite abundant in the
