propodcum consute ; superior face with irregular transverse well 

 separated line rugae ; the surface hetween tesscUate : with an imper- 

 fectly defined triangular basal area extending over on the declivity ; 

 posterior face transversely rugose or striate divided by the longitudinal 

 sulcus ; sides of propodcum finely longitudinally striate. 



Tergites very finely but strongly punctate the interspaces, two or 

 three times as wide as a puncture ; first, second, and third tergites 

 with margins depressed, more narrowly laterally ; the depression of 

 second^ and third is not quite one-third the length of the tergite. 

 Sternite shining, more coarsely punctured, the margins testaceous. 



Nervulus nearly interstitial, first recurrent received by the first 

 cubital cell. 



Male : Similar to female Init the hind tarsi with the first and second 

 joints pale. 



The clypeus produced into a narrowly rounded tooth. The last joint 

 of antennae longer than broad about as long as the three preceding 

 joints. Next to last and preceding joint shorter above than below. 

 Basal area of propodcum more definitely finely rugostriate, the striae 

 radiating from the central furrow. Seventh sternite entirely concealed, 

 eighth produced in the middle into a broad, flat truncate process a little 

 longer than broad and about 1-3 the width of the sclerite. 



Described from a single female specimen secured Lv 

 sweeping- at Waianae village, Oalm, at sea level, May 23, 

 1919 (Bridwell), and a male from Ewa Coral Plain bred 

 from a cocoon in the borings of Neoclytarlus euphorbiae. 



It is not absolutely certain that this is an immigrant 

 species, since several endemic Hymenoptera (jccur in the 

 locality where it was foimd. It is, however, probable that it 

 is introduced through commerce, possibly from Central Amer- 

 ica or Mexico. 



Xamed in honor of Mr. S. A. Rohwer, who has described 

 a majority of the ]N'orth American species. 



Some dead Eaphorhia wood containing the borings of Neo- 

 clytarlus euphorbiae Bridwell was taken at Sisal on the Ewa 

 Coral Plain on August 31, 1919. The examination of two 

 pieces of the main stem of a bush, probably from the same 

 bush, revealed four cells constructed by this wasp. Each cell 

 occupied the pupal chamber of the Neoclytarlus and the open- 

 ing through which the adult beetle had emerged was plugged 

 up with bits of coral, mud and vegetable debris, in one in-
