HEMIPTERA 159 



Another almost cosmopolitan genus, not yet however recorded from New Zealand 

 or from the Northern parts of the Palaearctic Region. Two species are recorded by 

 Scudder from the Olisfocene of Colorado. 



( I ) Astounia periiviaiius, Guerin. 



Lygaeiis pcnivianus Guer., 1838, Voy. Coquille, Ins. p. 178 [1831, PI. xii. fig. 16]. 



Hab. Oahu, Honolulu (Stal) ; " I have three specimens... of what I believe to be 

 this," obtained singly by sweeping ferns at a considerable elevation on the Waianae 

 Mountains, and Haleakala, Maui (Blackburn, Proc. Linn. Soc. N. S.W. (2) in. p. 344). 

 Mr Perkins has not collected it and it is unknown to me. It has been recorded also 

 from California, Puna, and Guayaquil. Distant (18S3, Biol. Centr. Amer., Rhynch. i. 

 p. 233) mentions " D. fc rruginetis from Honolulu. ..probably a MS. name of the late 

 Dr Stal."

Another almost cosmopolitan genus, which (or one very closely allied) occurs not 

 infrequently in Prussian amber and various other early Kainozoic formations ; also 

 a close relation from the English Lower Lias.
