344 NOTES ON THE HEMIPTERA OF THE HAWAIIAN ISLANDS, 



Of Coleotichtis I have a mutilated specimen taken from a 

 spider's web on Konahuanui, Oahu, at an elevation of some 2000 

 feet, which appears to be distinct from C. Blachhurnice. White. 

 It is more elongate, with the sui'face of the thorax uneven, but 

 is not fit to describe fully. 



Between Geotomus subtristis, White, and 0. jucundus, White, 

 I can find only colour difierences. The two occur in company, 

 and form, in my opinion, only one species. 



I have three specimens, not in first-class condition, of what I 

 Vjelieve to be Dysdercus Peruvianus. They were obtained singly 

 by sweeping ferns at a considerable elevation on the Waianae 

 Mountains, Oahu, and Haleakala, Maui. 



Nysius. 



N. longicollis, sp.nov. Angustus, nee nitidus, pallide griseo- 

 testaceus ; antennarum articulo primo, et pedibu.s, nigro maculatis ; 

 antennarum articuli secundi apice et articulis 3-4 totis, capitis 

 lateribus, vitta transversali post thoracis marginem anteriorem, 

 scutelli parte media, et corii margine apicali (partim) vittisque 

 duabus discoidalibus, nigrescentibus ; membrana nigro-umbrata- 

 Subtus griseo-niger ; antenuis sat brevibus ; capite pronoto 

 scutelloque densiiis nee fortiter punctulatis ; pronoto antice sat 

 fortiter augustato, longitudine latitudini sequali. Long. 4^ mm. 



Allied to my Nysiust no. 72 (in the hands of Dr. White), as 

 regards the shape of the pronotum. There is a broad transverse 

 band (which is somewhat enlarged backwards about its centre) of 

 a blackish colour. The middle part of the apical margin of the 

 corium is bi'oadly blackish, and two broad blackish fasciae proceed 

 from this blackish margin along the disc to a little past the middle 

 of the corium. The nervures ai'e of a pale brown colour. The 

 beak is shorter than in Nysius no. 72, the distance of its apex fi'om 

 the front margin of the eyes being not greater than that from the 

 front margin of the eyes to the back of the head.
