330 ICHlfEUMONIDJE. 



filiform and somewhat stout, extending to the anus, are entirely 

 black with only the apex of the scape pale testaceous boneath ; 

 the second segment is, like the remainder of the finely pubescent 

 abdomen, finely and closely punctate ; and the apices only of the 

 hind trochanters, the basal two-thirds of their tibiae, with the 

 extreme base of the metatarsi, are stramineous. 



Genus EXACRODUS, Font. 

 Exacrodm, Forster, Verb. pr. Kheinl. 1868, p. 210. 



GENOTYPE, not indicated. 



Head transverse, subbuccate and posteriorly not broader than 

 the internally entire eyes ; labrum hardly exserted ; upper rnandi- 

 bular tooth entire and shorter than the lower ; clypeus neither 

 discrete nor elevated, its apex simple ; face deplauate. Meta- 

 notal areae complete and strong ; notauli wanting. Scutellum 

 apically simple. Abdomen subpetiolate and not compressed ; 

 spiracles very slightly before centre of the basally narrowed and 

 normal first segment. Legs slender, hind femora not elongate 

 nor the intermediate dentate ; tarsal claws not pectinate ; hind 

 tibiae bicalcarate. Areolet wanting, stigma of normal size. 



The following species agrees very well with Forster's description 

 of this genus, and, though no species have hitherto been assigned 

 to it, it is better, I think, to adopt a known name than to erect a 

 new genus. 



235. Exacrodus populans, sp. n. 



<5 . A black and somewhat slender species, with white pilosity. 

 Head posteriorly subbuccate, but slightly narrower than the 

 prominent eyes ; frons and vertex convex and closely punctate ; 

 occiput bordered and centrally subemarginate ; face subdeplanate 

 and closely punctate, with a small central tubercle below the 

 antennae ; clypeus not at all discrete or reflexed, deplanate, with 

 its apex smoother and broadly rounded ; mandibles entirely red, 

 with the base as broad as the cheeks. Antennae, multi-articulate 

 and as long as the body, black, with the pedicellus entirely and 

 the scape beneath dull ferruginous. Thorax immaculate and 

 somewhat short ; mesonotum subnitidulous and closely punctate ; 

 metanotum shining and more finely punctate, with strong area? ; 

 basal area small and transverse ; areola a little longer than broad, 

 parallel- sided, basally rounded and apically truncate, emitting 

 strong costulae from its basal third ; petiolararea short and entire, 

 subrectangular and a little broader than long ; spiracles minute. 

 Scutellum black, subconvex, not bordered, but broadly excavate 

 basally. Abdomen shining and pilose, subfusiform, broader beyond 

 centre, dull ferruginous, with the two basal segments, and anus
