244 THE CANADIAN ENTOMOLOGIST. 



ON SOME HAWAIIAN HEMIPTERA- HETEROPTERA. 



BY G. W. KIRKALDY. HONOLULU, HAWAIIAN ISLANDS. 



Fam. Myodochid/E. 

 In the "Fauna Hawaiiensis — Hemiptera," in dealing with White's 

 species of " Cynuis," I had specimens before me of C. criniger only; since 

 then I have seen White's C. calviis, and another species allied thereto, but 

 with substylate eyes ; these three form three genera, distinguished as 

 follows : 



1. Eyes substylate, prominent, extending laterally well beyond the pro- 



notum, which is distinctly longer than wide ; tegmina scarcely 



punctured Nesoinartis, gen. nov. 



la. Eyes sessile, not prominent, not extending laterally so far as the 

 transverse pronotum ; tegmina strongly punctured 2. 



2. Ocelli as far from one another as from an eye. Pronotum with a 



distinct transverse impression basal of the middle 



Nesocymus, gen. nov. 

 2a. Ocelli much nearer to the eyes than to one another. Pronotum not 



transversely impressed , Sephora, Kirkaldy. 



The character of the nonpunctuation of the tegmina in Nesomartis 

 would remove it from the Cyminae in the usual acceptation of the subfamily, 

 but it is obviously closely related to Nesocymus and Sephora. I cannot 

 find any character to separate satisfactorily the Cyminpe from the 

 Astacopinse (Lygjeinse of some authors), and the amalgamated subfamily 

 should be known as Cyminae. Stal (Hem. Afr., ii, 120) relies on the 

 tegmina being wider than the abdomen, and the exterior margin of the 

 corium dilated, while his "Lygjeida" have the tegmina not, or only partly, 

 dilated and wider than the abdomen, but the latter is not the case in many 

 forms. I think that Nysius is more closely allied to Cymus than it is to 

 Stalagmostethus and its allies. 



Sephora, Kirkaldy. 

 Sephora, Kirkaldy, 1902, Faun. Haw., iii, 161. 



The rostrum barely reaches to the middle coxae, first segment 7iot 

 extending quite so far as the base of the head. Collar feebly marked, 

 pronotum scarcely constricted there, and not constricted again towards the 

 base. Ocelli much nearer to the eye margins than to one another.
