as reported in the present volnnie of these proceedings, pp. 222 

 and 223. Snbsecpiently on Feb. 6, 1916, he took it upon the 

 elevated coral reef east of Diamond Head. Early in April 

 the writer found it abundant aniong- the flowers and on the 

 foliage of l-h( (Araria fanicsifuiH) and algeroba (rrosopis 

 juliflora) along the road on the ocean side of Diamond Head. 

 Mr. Swezey took it near Pearl City on Sept. 11; the writer 

 found it among the grass on the Ewa coral plain below Sisal 

 on K^ov. 28; and Mr. Swezey on Jan. 17, 1917, in the cane- 

 fields above Waipio. I found it in November, 1916, at the 

 base of Koko Head crater under stones with Tenebrionid 

 l)eetles. i\Ir. Fullaway informs me that ]\Ir. Giffard and he 

 have taken it in 1917 at th(> Xuuanu Pali. 



In its behavior it is much like the smaller species of 

 Tipliia''. 1 have frequently seen it I'unning about on the 

 ground and in one case it entered the ground in an exploratory 

 way thru a crevice. I believe it to be parasitic upon the larvae 

 of some or all of our species of Tenebrionid beetles (Alpliito- 

 hius. Gonocephahnn, and Blapstinus) which are abundant 

 in the areas where the wasp has been taken. So far as I can 

 learn none of the species of Epyvis have been bred but I have 

 taken a smaller Epyvis at Capetown carrying in its jaws a 

 Tenbrionid larva larger than itself, and Mr. H. T. Osborn 

 observed near Pearl City on Sept. 4", 1915, while searching for 

 traces of Tipliia larvae on Anomala grubs, a Tenebrionid larva 

 parasitized by an external Hynienopterous larva resembling that 

 of Tipliia. This perished without transforming, but as we know 

 no other wasp here to which the larva could well be assigned, 

 T am convinced that he had the larva of our Epi/ris before its 

 adult had been discovered. 



The species corresponds to none of the Xorth /American 

 species of Epyris described by Ashmead under }[rsifiHs nor 

 with the European forms so admirably described by the Abbe 

 Kieffer. Tt is here described as new: 



* I am convinced that the association of this family with the 

 Scolioid wasps and the Chrysididae is eminently natural and that any 

 resemblance with the Serphoid (Proctotrypoid) forms is purely super- 

 ficial.
