genera and species of Hymenoptera. 191 



EVANIIDjE. 



Evania sericea, n. s. 



Black ; palpi, knees, anterior tibiae, and tarsi obscurely 

 fuscous. Head and thorax coarsely rugose ; petiole 

 longitudinally rugose, smoother at the base ; mesopleura 

 in front smooth, shining, impunctate, behind coarsely 

 reticulated ; breast covered with large shallow punctures. 

 Coxae finely rugose, smooth at base. Posterior femora 

 not much longer than thorax; tibiae and tarsi armed 

 with short thick bristles ; tarsi not much longer than 

 tibiae ; claws apparently simple. The head, thorax, and 

 legs at the base are closely covered with a white velvety 

 pubescence, which is longest at the sides. Abdomen 

 smooth, shining, compressed, shortly pilose at the sides. 

 Antennae longer than the body; the apex of scape 

 brownish. Wings hyaline ; cubital and discoidal ner- 

 vures obsolete from the discoidal cellules, the upper of 

 which is not at all so broad in proportion to the lower 

 as it is in E. laevigata ; the transverse humeral nervure 

 is interstitial. The mandibles have two short obtuse 

 teeth besides the large apical one. Length, 7 mm. 



This species is apparently most nearly allied to E. 

 tasmanica, Westw., but the present species has not the 

 face longitudinally striated. 



Hab. Oahu and Hawaii (No. 131). 



ICHNEUMONID.E. 



Limneria polynesialis, n. s. 



Black ; tegulae, trochanters at apex, and middle of four 

 posterior tibiae, yellowish white ; base and apex of four 

 posterior tibiae and femora reddish ; anterior legs pale 

 testaceous, the tibiae with a more yellowish tinge ; pos- 

 terior tarsi infuscated. Abdomen on the under side at 

 the sides, and more or less above, reddish ; segmental 

 divisions yellowish white at the sides, and more or less 

 above on the three apical. Head and thorax semi- 

 opaque, 'finely punctured, covered (especially the face) 

 with a white pubescence. Super-median areola distinct, 

 semicircular ; the others are somewhat compressed ; pos- 

 terior median triangular at base, and extending to the 

 apex. Antennae as long as the thorax and abdomen, 

 black, obscure fuscous beneath. Terebra curved, a little
