above. Thorax eeneous, pleurae moderately dark yellowish or 

 aeneous-grey, shiniug; ; scutellum browuisli-yellow, all with dense 

 brownish-yellow pubescence; rather paler on pleurae. Abdomen 

 black ; 1st segment shining seneous ; a pair of rather large, oval, 

 well separated yellow spots across centre of 2nd segment, dis- 

 tinctly passing over side margins near upper corners ; 3rd and 

 4th segments each with a pair of large, oval or oblong spots with 

 rounded corners filling most of the surfnce, passing at their upper 

 corners more or less broadly, but always distinctly, over side 

 margins ; the spots often joined in median line in J narrowly or 

 broadly ; never so joined in $ . These spots lie more broadly on 

 anterior margin of 4th segment than on 8rd, being ni some indi- 

 viduals just clear of margin on 3rd segment ; when this is the 

 case they are generally more broadly united on 4th than on 3rd 

 segment, as in some individuals they may form a pair of spots on 

 3rd segment whilst united as a distinct band on 4tb. Hind 

 margin of 4th segment orange ; 5th segment orange, indistinctly 

 darkened in middle. Genitalia large, sliining black above, orange 

 below. Pubescence of abdomen following ground-colour; pale on 

 1st segment and anterior corners of 2Dd ; black on side margins 

 from hind part of 2nd segment to tip; pale yellow on genitalia. 

 Venter yellowish with indistinct black markings, pubescence pale. 

 Legs orange ; basal half of anterior, and two-thirds of hind, 

 femora, black ; hind tibiae indistinctly darker on outer side; tarsi 

 brownish or blackish, paler basally ; pubescence mainly pale 

 yellow, some short black pubescence behind femora and (in addi- 

 tion) below hind pair and on hind tibiae. Wings practically clear; 

 stigma yellowish ; halteres orange.

Described from five 6 S in good condition in my collection, 

 taken by me at Darjiling, 6900 ft., 2. vi.-15. v. 1917, also a S and 

 two $ $ in Indian Museum from Shanghai, i. v. 1906 (Brnnetti). 

 There seems no doubt of the identity of this common European 

 species, the Oriental examples agreeing practically thi-oughout 

 with Verrall's description. Its range includes all Europe, Madeira 

 and Canaries, N. Africa, A.sia to Japan, and perhaps N. America.
