white .s})ots and fascia?, with the legs entirely pale. Head 

 black : antennee fulvous ; the scape in front, the clypeus, and 

 mandibles yellowish white ; the tips of the latter ferruginous. 

 Thorax black : the prothorax, a large square spot tridentate 

 at its anterior margin, the tegulffi, scutelluni and postscutellum, 

 a large subquadrate macula beneath the wings, and the legs 

 pale yellow ; the coxaj and femora at their base above more 

 or less fuscous ; wings hyaline, the nervures of the anterior 

 pair black, those of the posterior pair fuscous. Abdomen 

 black : the first segment with a white apical fascia, on the 

 other segments it is basal, broad, occupying two thirds of the 

 segments, and each fascia is narrowed in the middle, being 

 angularly incised at the posterior margin ; beneath, the fasciae 

 on the segments are very deeply incised and become oblong 

 divergent maculge. 



Hub. Sind. This species is in the Indian Museum. 



This genus was established by Prof. Westwood in the new 

 series of the Transactions of the Entomological Society of 

 London, vol. i. ; a figure of the type, Isioara luteus^ is given. 

 This Indian genus is at once separated from the other genera 

 of the family of Thynnidte by the form of the marginal cell 

 of the anterior wings, it being truncate at the apex, and emit- 

 ting a short appendicular vein. 



Family Pompilidse. 



Genus Salius, Van der Lind. 



Salius bipunctatus. 



Male. Length 4 lines. Black, smooth, shining, and im- 

 punctate, with a subovate white spot at the lateral angles of 

 the metathorax. Head ovate ; the antennge inserted on each 

 side of a prominence above the clypeus, the prominence has 

 a central impressed line ; a minute white line on the face at 

 the lower orbits of the eyes. Thorax : the posterior margin 

 of the prothorax subangular ; wings slightly fuscous, with the 

 apical portion of the anterior pair darkest ; the intermediate 

 and posterior tibise and tarsi with a few fine short spines. 

 Abdomen as long as the head and thorax united. The entire 

 insect with a fine changeable hoary pile, which is only ob- 

 servable in certain lights. 



Ilab. Tuscany. 



This species agrees with the Salius sexpuncfatus of St. 

 Fargeau in having two white spots on the metathorax ; but it 

 has no trace of the large white spots, on the second and third 

 segments of the abdomen, which distinguish that insect. St.
