and sublaterally with numerous fuscous-ringed tubercles which bear 

 scarcely perceptible hairs, with 2 contiguous fuscous mammiform tuber- 

 cles near the base in the middle, etc. Tegmina hyaline, very strongly 

 particoloredly iridescent, subcostal ('costal') cell and stigma, veins and a 

 V apically, pale fuscous. Legs pale, fore and middle femora with a 

 fuscous annulation, hind femora broadly fuscous apically, hind tibiae 

 fuscous basally; coxae more or less fuscous. Honeytubes short, pale 

 fuscous. Antennae scarcely as long as body, 6, 5, 30, 24, 22, 14, 12, the 

 seventh not really separated from the sixth. Stigma rather long, longer 

 than broad, curved. Length to apex of abdomen about 1.25 mill., to 

 apex of flight organs about 2 mill. 



Hab. Oahu, Honolulu, on Lagerstroemia indica an introduced plant 

 (G. W. K.); also on other shrubs. 



Nymph: pale yellow, eyes red as in adult. Head, nota and abdomen 

 multituberculate dorsally and laterally, each tubercle with a black, capi- 

 tate bristle. 



This species agrees with MonelUa in that it carries its organs 

 of flight horizontally while walking and in repose, but its struc- 

 ture is that of Myzocallis.

By G. W. KiRKALDY. 



No Thysanoptera have yet been described from the Hawaiian

Agnostochthona gen. nov. 



Belongs to the Tubulifera and differs from Anthoihrips Uzel by the ver- 

 tex being very slightly longer than wide anteriorly and slightly though 

 distinctly wider anteriorly than posteriorly ; it is also longer than the pro- 

 notum medianly. Face elongate, angularly rounded at the apex, reaching 

 nearly to the base of the prosternum. First segment of antennae as long 

 as, or longer than, the second, and is much stouter; third and fourth a 

 little wider than the others. Tegmina not constricted medianly. Spine 

 on the fore tibiae somewhat large in the female. 

 1. alienigera sp. nov.

 6th-8th, antennal segments. Eyes rounded, not protruding. Ocelli widely 

 separated, large, posterior pair contiguous with the internal margin of the 

 eyes, front one almost between first segments of the antennae, which are 

 subcontiguous. Relative lengths (from base) 6, 6, 8, 10, 8, 8, 6, 5; 3rd 

 6th, basally subpedicellate ; hairs moderate. Postocular bristles very long,
