HYMENOPTERA FROM JAPAN AND THE PACIFIC. 265 



ECHTHROMORPHA WALKERT, n.s. 



Black ; scape beneath, labrum, clypeus, palpi, orbits 

 narrowly, a small mark beneath the tegulae, a 

 larger one lower down, base of scutellum, post- 

 scutellum, two large marks on metanotuni, coxae, 

 trochanters, and all the femora at sides and beneath, 

 interior tibiae and tarsi, and middle tibiae in front, 

 yellow; wings hyaline, nervnres black, stigma 

 fuscous on lower side. Antennae longer than the 

 body, covered with a microscopic pile ; third joint 

 one-fourth longer than the succeeding ; apical joints 

 produced slightly at base and apex. Head closely 

 punctured, excavated above the antennae, but not 

 so deeply between them, where a triangular elevated 

 portion comes down from the ocelli, immediately in 

 front of which this part is hollowed; face covered 

 with white pubescence ; thorax coarsely punctured, 

 the hind part of the meso- and metapleurae longi- 

 tudinally and coarsely striated ; scutellum punctured; 

 post-scutellum imi^unctate, apical half of metanotum 

 finely transversely aciculate-striated ; petiole trans- 

 versely striated, hollowed (very broadly at the 

 base) in the middle. The other segments strongly 

 punctured, broadly white at the apex laterally; a 

 transverse suture at apex of the white marks, in- 

 terrupted in the middle ; areolet subpetiolate. 



Long. 11*5 mm. 



Hah. Tahiti, Society Islands (J. J. Walker). 



The species of this genus are only known from 

 ■Oceanic Islands; E, maculipennis, Holm., from the 

 Sandwich Islands, E- afrata, Holm., from St. Helena, 

 .and E. mixta, Him., from Ascension. 



EVANIA CURVINERVIS, n.s. 

 Similar in coloration to and somewhat larger and 

 :stouter than E. laevigata, Latr. ; but differing from 

 it in the antennae being slightly shorter in propor- 

 tion to the body, and stoviter; in the pubescence 

 being much denser ; in the front being more deeply 

 excavated and without any keel; in the pro- and
