Hcni'deJes tencUus (Say). Ashniead divided onr Ilemi- 

 teles among tliree so-ealled species, namely fcnrlhis (Say), 

 vanefjatus Ashmead and ineUtacac Ashmead. Ever since the 

 writer became acquainted with the character of the Hawaiian 

 fauna he had been skeptical ahoiit these determinations. It 

 seemed ini])rol)al)le, to say the least, that three closely allied 

 species should become established here, and moreover all the^ 

 material that was extant in the local collections was clearly 

 refcralde to a single species. A study of the Ilemiteles 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 tcitrlliis (Say), (///7/.s Norton, and the fV^llowing 

 all descril)e(l by Ashmead: nielHaeae , variegatus. coleopliorae, 

 uryylae and pcriliti. the last two under Otacustes. Although 

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

 hopeless to attem])t to distinguish more than one by means of 

 any descriptions so far ])ublished, and until the genus receives 

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

 writer recommends that the earliest American name, or tenclJns 

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

 the Hymeno])tera of Connecticut, Viereck goes one step fur- 

 ther and makes tenellws a variety or subspecies of the European 

 areator (Panzer). This parasite has been reared frequently 

 in the Islands from the cocoons of Chrysopa Diicrophija Mc- 

 Lachlan. It is pi-obably distributed on all of the Islands, as 

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



Aiujiilti pol line. si alls (Cameron). Viereck's species plu- 

 fclhtc and Jiclhihw are synonymous with Cameron's polyiic- 

 sialls. Viereck separated his two species on the ])resence 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
