difference in the transverse carina of the propodeum, and 

 it further has the palpi pale and the tibiae and tarsi rufous. 



Enicospilus dispihis, sp. nov. 



(J 9- 16-18 m.m. Black; face in ^ brown or dark brown, 

 clypeus and labrum pale ferrugmous or yellowish, front and hind 

 orbits pale yellow, the yellow of the latter discontinuous, not meeting 

 behind the ocelli. Antennae dark fuscous. Thorax and basal segment 

 of the abdomen black, the third segment more or less evidently 

 tinged with dull ferniginous, the rest blackish fuscous. Femora 

 black, tibiae and tarsi dark brown or fuscous, front tarsi sometimes 

 paler. 



Face finely and densely punctured, antennae in ^ extending 

 beyond apex of the spread wings by a length about equal to that 

 of the marginal cell, in the 9 somewhat shorter ; ocelli very large. 

 Mesothorax finely and very densely punctured, propodeum with 

 very dense rugulose sculpture which is evidently finer on the anterior 

 third, the transverse carina very distinct in both sexes and shining. 

 Wings fusco-hyaline with dark neuration, discocubital cell with a 

 larger pear-shaped or subtriangular spot on the basal side of the 

 hyaline hairless space, and a minute roundish one situated well 

 within this space. 



Hab. Koolau range of Oahu. 



Extremely like E. mauicola, Ashm., except for the second 

 spot in the discocubital cell and the less smooth surface of 

 the anterior third of the propodeum. 



Enicos])ilus dispilus, var, j9a//?^>es. 

 Hardly difterent to the type in the structure, but readily dis- 

 tinguished by the clear rufotestaceous antennae, tibiae and tarsi 

 and the more or less rufescent femora. 



Hah. Mountains of Kauai. 



Enicosjnlus dimidiatus, sp. nov. 

 5 . Closely allied to and greatly resembling E. mauicola, Ashm., 

 but difi'ering in the following characters. It is much smaller, the 

 length being only 11 m.m. The face is excessively finely and 

 indistinctly punctate, the yellow lines along the anterior orbits 

 extremely narrow, the antennae are brown and not very dark- 

 coloured. The propodeum posteriorly is much more finely rugulose, 

 the transverse carina very faint, only perceptible on the middle third, 

 being effaced at the sides. The wings are clearer.
