intermediate tarsi moderately thickened and spinose. Tarsal 

 ungues bidentate. 



Black, the pubescence cinereous ; a spot on each side of 

 the first dorsal abdominal segment, a smaller one on each 

 side of the second, and a narrow transverse band narrowly 

 interrupted in the middle near the apex of the third segment 

 yellow. Spines of the tibiseand tarsi dark fusco-ferruginous. 



Length 16 mm.

Allied to T. serriger, Sharp, and T. olivaceus, Turn., and 

 belongs to the genus Thynnus in the most limited sense. 



Anoplius {Episyron) froggatti, sp. n. 



? . Clypeus three times as broad as long, the apical 

 margin transverse, not rounded. Second joint of the flagel- 

 lum long, the first and second equal in length to the third 

 and fourth combined. Eyes separated on the vertex by a 

 distance about equal to the length of the third joint of the 

 flagellum, the posterior ocelli a little further from each other 

 than from the eyes. Pronotum short, broadly rounded ante- 

 riorly, the posterior margin very feebly arched. Scutellum 

 large, slightly convex, broadly rounded at the apex. Median 

 segment as broad at the base as long, slightly narrowed to 

 the apex. Abdomen subsessile, opaque, the sixth dorsal 

 segment narrowly rounded at the apex. Tarsal ungues bi- 

 dentate, tibise spinose. First and third abscissae of the radius 

 equal, united a little longer than the second, the second 

 cubital cell half as long again as the third on the cubital 

 nervure, the recurrent nervures received by the second and 

 third cubital cells respectively beyond two-thirds from the 

 base; cubitus of the hind wing originating just before the 

 transverse cubital nervure. 



Opaque black, the margins of the eyes very narrowly, 

 broadly interrupted on the summit, a spot at the apex of the 

 coxas and a spot on each side at the base of the third dorsal 

 segment of the abdomen dull creamy white; clypeus and 

 front clothed with fine white pubescence ; postscutellum, 

 median segment, and first dorsal segment of the abdomen 

 thinly covered with blue scale-like hairs. Wings hyaline, 

 the apex fuscous from the apex of the radial cell. 



Length 11 mm. 



Hab. Solomon Islands {Froggatt) . July. 



Very near papuensis, Sm., but differs in the clypeus, which 

 is rounded in papuensis at the apex ; the present species also 

 has the third abscissa of the radius longer and the apical
