HEMIPTERA 



{Heteroptera) 



REDUVIIDAE 

 MIRIDAE 



{Zelus reji a r-dii = pe regrinus ) 

 {Hyalopeplus pellucidus) 



TINGIDAE ( Teleonemia lantanae) 



The lantaiia Tingid {Teleonemia la7iia?iae) \b noi thickly dis- 

 tributed so far as I could see, which fact is no doubt due to Ian- 

 tana, its food plant, being scarce on the Island. Lantana has 

 never been a pest on Lanai which fact is no doubt due to the in- 

 troduction, by a former owner of the Island, of Prof. Koebele's 

 lantana insects some of which have the effect of preventing its 

 spread. Its scarcity on the Island is most marked and during 

 my 33>^-day visit I never saw a plant of it although the owner of 

 the Island informs me that he occasionally comes across a few 

 small patches in remote spots. 



The number of species of endemic insects seen and taken in the 

 valleys mentioned, was very discouraging considering the hard 

 tramping it was necessary to do in order to get over the ground, 

 but a trip from the Ranch house to the summit of the mountain 

 at Haalelepakai, which as I said before is at an elevation of 3,400 

 feet, is well worth making, even if it only allows one the oppor- 

 tunity for 3 or 4 hours collecting in any one day. This small 

 forest section certainly seems more natural as a collecting ground 

 for the entomologist, but even here the paucity of insect fauna is 

 marked when compared to similar situations on some of the other 

 Islands in the group. It is quite certain that if one intends to 

 make a successful day of it there, one cannot afford to loiter on 

 the collecting ground or en route. On the day I visited the moun- 

 tain, Haalelepakai and the adjacent forest were enveloped in mist. 

 This was varied with occasional showers of drizzling rain making 

 collecting disagreeable, but for a third of the time, however, there- 

 were glimpses of sunshine during which I hoped to see some of the 

 native Aculeates flying about. In this I was extremely dis- 

 appointed and my visit to Haalelepakai in this respect produced 

 the same result as was experienced in the valleys below — ab- 

 solutely nothing of any kind on the wing other than the common 

 blow- fly. I was more fortunate with other things, particularly 

 with Coleoptera which ranks equally with Aculeate Hymenoptera
