propodeuui cunsute ; superior face with irregular transverse well 

 separated tine rugae; the surface between tessellate ; 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 propodeum 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, tlie margins testaceous. 



Nervulus nearly interstitial, first recurrent received by the first 

 cubital cell. 



Male: Similar to female but tlie iiind 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 propodeum 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 tlie width of the sclerite. 



Described from a single female specimen secured by 

 sweeping- at Waianae village, Oalm, at sea level. May 2'>, 

 1919 (Tjri<l\vcll), ;ind a male fi-oiii JMva Coral i*laiu bred 

 from a cocoon in the borings of Xcorlj/larlus euphorbiae. 



It is not absolutely certain that this is an immigrant 

 species, since several endemic Ilymenoptera occur in the 

 locality where it was found. 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 North American species. 



Some dead Eu/pliorbia wood containing the ])oi'ings of Kco- 

 clytarlus euphorhiae Bridwell was taken at Sisal 011 the Ewa 

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

 pieces of the main stem of a bush, )>robably fi-om the sanu^ 

 bush, revealed four cells constructed by this was]). Each cell 

 occupied the pu]»al chaiid)er of the Neorl i/f(irlu>i and the open-
