HEMIPTERA 535 



Fam. MYODOCHIDAE. 

 Metrarga. 



Metrarga, huj. op. in. p. 165. 



I have recently founded two subgenera in this, viz. Nesocryptias and Nesocliniacias 

 (1908, P. Haw. E. S. I. p. 189). 



The forms now known are : 



a. typical subgenus : 



M. nuda (F. H. in. p. 165) typically apparently an Oahuan species, with 



var. mauiensis (1908, P. Haw. E. S. i. p. 188). 

 M. obscura (F. H. iii. p. 166) ; I have recently taken this at Kilauea, Hawaii, 



on Ohia lehua i^Nani polyniorpha). 



b. subg. Nesocliniacias. 



contractu (F. H. in. p. 166); with vas. picea (1908, P. Haw. E. S. i. p. 188). 



(i) lanaiensis (1908, 1. c), sp. n. 



c. subg. Nesocryptias. 

 villosa (F. H. in. p. 167). 



Dr Perkins writes me that the species of Metrarga are " certainly not bark- 

 dwellers, unless as a rare and exceptional case." 



Sephora crinigera White. 



SepJwra criniger, huj. op. in. p. 161. See also Kirkaldy, 1907, Can. Ent. 

 XXXIX. p. 244. 



Nesomartis. 

 Nesomartis Kirkaldy, 1907, op. cit. p. 245. 



(i) Nesoviartis psammophila Kirkaldy. 

 Nesomartis psammophila' Kirkaldy, 1907, 1. c. 



Hab. Oahu, "on the coast on the ground amongst Sida" grass etc., and 

 "Hawaii, Kona coast in similar situations" (Perkins). Probably introduced. 



Nesocymus. 



Nesocy^nus, Kirkaldy, 1907, 1. c. 



Apparently allied to Cymoninus Breddin, but there is no percurrent main vein on 

 the corium, at least not one at all which " teilt das Corium in zwei annahernd gleiche 

 Telle," and while the corium is partly punctured, partly smooth, it is the middle oblique
