new forms or of distribution; the botanists and entomologists 

 have still much to learn in those directions, and a fuller knowl- 

 edge will lead to a better understanding of the phylogeny of 

 the various groups ; that such added knowledge will change 

 the aspect of our fauna and flora is exceedingly unlikely. 



Note. 



The following new Nesosyd)}(' has been found by ]\Ir. P. 

 II. Timberlake since the completion of the above: 



Nesosi/dnc Joheliae sp. n. 



^ Brachypterous; antennae reaching to about middle of clypeus, 

 first joint more than half the length of second; median frontal carina 

 furcate at extreme base or only thickened over that area; length of 

 vertex about twice the width; hind legs considerably longer than 

 body, first joint of tarsus longer than other two together, spur nearly 

 as long as first tarsal joint, narrow, with 12 teeth on hind margin. 



Brown or fuscous brown, carinae of head and thorax, clypeus, 

 leKS and ventral surface of thorax lighter, base of abdomen and line 

 along dorsum lighter. Tegmina hyaline, tinged with light brown, 

 veins darker with minute granules bearing black hairs; a dark fus- 

 cous spot at apex of subcostal cell and another at apex of clavus. 



Pygophor broadly open, similar to N. sharpi: anal segment also 

 very similar to that species, but the spines forming a broad, flat 

 process at each ventral corner with a small spine at apex; styles 

 very like those of N. umilupensis, but slightly shorter and broader; 

 aeadegus thin, tubular, slightly curved upward, a row of small spines 

 from dorsal point on apex across left side to a ventral point about 

 middle, another similar row on right side with the spines larger and 

 extending more basally, the last three spines along the ventral surface. 



Length 3 mm. ; tegmen 2 mm. 

 2 Similar to male. 



Length 3.5 mm. ; tegmen 2.4 mm. 



Hab. Oahu, Kaumuohona ridge, Koolau IMountains, on 

 Lobelia hypoleuca Ilbd. One male and a series of females 

 (P. H. Timberlake, April). Type in coll. H. S. P. A. Exp. 

 Sta. 



This species comes next to N. limilupensis.
