Mr. Wallace says of this species, " A common house-wasp in Macassar ; 

 builds mud cells on rafters." 



Note, — In describing the species of this genus collected by Mr. Wallace 

 at Borneo, I incorrectly gave that locality for P. javanus. The insect 

 mistaken for that species may be shortly characterized as P. benignus, 

 length 12 lines. Opake-black, with the petiole shining ; the meta- 

 thorax transversely striated ; the wings pale fulvo-hyaline, the ner- 

 vures ferruginous ; the scape in front, the anterior and intermediate 

 tibiae, the apex of the femora, and the basal joint of the tarsi reddish- 

 yellow ; the posterior legs, with the trochanters and basal half of the 

 femora, yellow. 



4. PELOP.EUS FLAVO-FASCiATUS. P. uigcr ; capitc thoraceque flavo 

 variegato ; pedibus abdominisque basi ferrugineis ; alis hyalinis, apice 

 fuscis, abdominisque segmento tertio fascia lata flava ornato.

 Thorax : the posterior margin of the prothorax, the tegulse, scutellum, 

 and a quadrr.te spot on each side of the metathorax at its base

 joint of the tarsi black ; wings fulvo-hyaline, the nervures ferrugi- 

 nous, a fuscous spot at the apex of the anterior pair; the meso- and 

 metathorax transversely striated, the latter with a yellow spot at the 

 insertion of the petiole. Abdomen : the petiole slightly curved up-
