llcmlicU'x Iriirllus (Say). Ashuiead divided our Hemi- 

 tf'h\s aiiioiiii- three so-ealled species, namely tencUiis (Say), 

 raricf/afiis Ashniead and inHifaeac Ashniead. Ever since the 

 writer l)ecanie acquainted with the character of the Hawaiian 

 fanna he had been skeptical al)<)ut these determinations. It 

 seemed improbable, to say the least, that three closely allied 

 species should become established here, and moreover all the 

 material that was extant in th(>- local collections Avas clearly 

 referable to a single species. A study of the Hemifelcs in the 

 Xational Museum showed that the following described forms 

 are extremely alike and might well belong to a single species, 

 although showing some variations in size and coloration. The 

 list includes Iciu'lhis (Say), ufiJis Xorton, and the following 

 all described by Ashniead: nielUacae. rariegatus, colcopliorac. 

 orgyiae and pcrllifi. the last two under Otacusfes. Although 

 there may be more than one species included here it would ho 

 hopeless to attempt to distinguish more than one by means of 

 any descriptions so far published, and until the genus receives 

 a thorough revision at the hands of a competent specialist, the 

 Avriter recommends that the earliest American name, or fencUus 

 (Say), be used for our Hawaiian ])arasite. In his work on 

 the Hymenoptera of Connecticut, Viereck goes one step fur- 

 ther and makes tendlus a variety or subspecies of the European 

 areator (Panzer). This parasite has been reared frequently 

 in the Islands from the cocoons of Chnjsopa mlrvoplnja ^fc- 

 Lachlan. It is probably distributed on all of the Fslands, as 

 the writer has seen it from Kauai, Oahu and Hawaii. 



Angitia jxjJijnesialis (Cameron). Viereck's species plii- 

 teUae and helluJae are syncmymous with Cameron's pohjnc- 

 slaVis. Viereck separated his two species on the presence or 

 absence of yellowish markings on the sides of the abdomen. 

 Hawaiian specimens usually have the yellowish markings and 

 are thus identical with the types of liellulae. Such specimens
