Oahu, practically all over the Koolau range from the forest level 

 upwards, but not common. 



var. purpurea no v. 



The entire upper surface, excluding the membrane, is more or 

 less suffused with purplish. It occurs apparently with the type- 

 form . 



63. M. ? fobritinctos (Blackburn). 



Blackburn does not mention the curious horns on the head, but 

 the incrassation of the antennae indicates its probable position in 

 this genus. 



Family Gerridae. 



64. * Microvelia vag'ans F. B. White. 



65. * Halobates sericeus Eschscholtz. 



Family Reduviidae. 



66. * Alloeocranum biannolipes (Montrouzier ). 



67. * Zelus renardii Kolenati { = laevicollis Champion and 

 peregrinus Kirkaldy ) . 



• I am indebted to Dr. Bergroth for the information i\\^i peregri- 

 nus and laevicollis are the same species. 



68. * Triatoma rubrofasciata (de Geer). 



69. Nesidiolestes selittm Kirkaldy. 



70. N* insolaris sp. no v. 



This differs so much from my description of N. selium, that I 

 fear there is some mistake therein. I cannot refer now, however, 

 to the unique type of the latter. 



N. insularis differs by the pronotum not being constricted (!), 

 and by the metanotal spine being subacute. The fore femora 

 are nearly twice as long as the coxae, and much longer than the 

 tibiae and tarsi together. In profile the head is much higher on 

 the anterior lobe than on the posterior; eyes small. Head and 

 thorax dorsally brownish-testaceous, more or less obscurely var- 

 iegate. The abdomen, and the insect laterally and ventrally, 

 piceous; base of abdomen above brownish, &c. The antennae, 

 femora and tibiae are brownish and testaceous in rings. 

 Length (? ^) 9 mill.
