THE CANADIAN ENTOMOLOGIST. 245 



The specimens before me agree fairly well with \Vhite's description, 

 except as follows : the general colour of the head is paler ; the membrane 

 is almost always faintly marked longitudinally with a fuscous stripe, and 

 the rostrum just reaches to the middle coxae, instead of to the middle of 

 the mesosternum, while the first segment does not reach as far as the base 

 of the head, instead of to the middle of the prosternum. I feel sure 

 White's description is incorrect in this. 



Hab. — Lanai and Molokai, as detailed previously ; White records it 

 from Maui at 5,000 feet, under stones, but Dr. Perkins informs me that 

 the specimens collected by him were beaten from the branches of trees, 

 where they probably live under moss or lichens. 



Nesocymus, gen. nov. 



Allied to the last, but the distances between the ocelli, and from an 

 ocellus to the nearest eye margin, are subequal. The rostrum reaches to 

 the middle of the mesosternum, the first segment reaching to the base 

 of the head. Vertex more convex, and eyes larger. Pronotal collar more 

 marked, the pronotum exteriorly rounded after this, and divided into two 

 parts by a median transverse very narrow impressed line. 



I. calvus (White). 



Cymus calvus, F. B. White, 1881, A. M. N. H. (5), vii, 56. 



Sephora calvus, Kirkaldy, 1902, Faun. Haw., iii, 162. 



Hab. — Oahu (as previously noted), at roots of herbage in the moun- 

 tains, from 1,500-2,000-ft. Dr. Perkins has lately collected a series of 

 forms agreeing with White's description, except as follows: there is always 

 a dark, broad, fuscous longitudinal stripe on the membrane (not noted by 

 White), and his rostral proportions do not agree. 



Nesoviartis, gen. nov.* 



Differs from the two preceding genera by the very transverse vertex 

 and substylated eyes, which extend laterally much further than the pro- 

 notum ; by the ocelli as close to one another as to the eye margins, and 

 being close to the anterior margin of tiie pronotum (they are somewhat 

 distant in the other genera), by the elongate, coUarless pronotum, whose 

 lateral margins are straight and scarcely divergent. Tegmina scarcely 



punctured. Rostrum reaching middle coxpe, mesosternum rather deeply 

 sulcate posteriorly. 



IV. psammopkila, sp. nov. 

 Pale greenish, drying to testaceous, with sparse whitish-pubescence, 

 a l?evigate elongate spot on each side of the pronotum anteriorly. 



*Nesos, island, martis, maiden.
