lo specimens ; 9 Olaa, Hawaii ; i Hilo, Hawaii ; in January, June, September, 

 and December. Allied to the preceding species, but perhaps not so nearly as the 

 close superficial resemblance leads one to believe, since when carefully considered 

 they differ in many respects ; the acutely angulated first line is the obvious distinction.
