with sparse short fine ^xUow hairs. Proboscis black with yellow 

 labella. Hinder orbit of eyes with whitish yellow scaly hairs, back 

 of head blackish gre3\ In profile the head does not extend down- 

 wards below the level of the eyes. 



Thorax. — Bright shining aenous with a bronze tint, with short 

 black or blackish brown hairs. Scutellum with dull black (almost 

 velvet black) dorsum, the colour becoming dark brown on the 

 hind margin ; the extreme base is narrowh?- pale yellow ; the surface 

 covered with black hairs. Sides of thorax dull aenous or aenous 

 gre3^, with a small quantity of yellowish or yellowish grey hair. 

 A small oblong, pale yellow, inconspicuous callus like spot on 

 each shoulder ; a small similar spot on the prothorax on each side 

 just above the first pair of coxae. Three elongate similarly 

 coloured small spots placed in a curved line below and behind the 

 wings, the lowermost spot situated on the sternopleura. 



Abdomen elongate, of uniform wndth, about as long as head 

 and thorax together, black; ist segment yellow except a little 

 blackish in the middle at the base ; 2nd segment with a pair of 

 elongate yelloAvish spots across the middle, their outer ends 

 touching the lateral edges of the segment, their inner ends well 

 separated. The 3rd and 4th segments each with a slightly arcuate 

 yellowish band, emarginate in middle on hinder side, placed just 

 before the middle of the segment, and almost attaining the lateral 

 margins (or if reaching them in individual examples, the contact 

 probably practically punctiform only). The 5th segment with two 

 oval yellow spots placed diagonally from anterior border to each 

 hind corner. The whole abdomen with fine short black hairs, the 

 sides also with black hairs ; very little pale hair about the anterior 

 corners of the abdomen. Belly mainly yellowish; the black parts 

 of the dorsum more or less duplicated below. 



Legs. — Anterior pairs pale yellow; an infuscated streak on 

 upper side of fore femora and on outer side of fore tibiae ; middle 

 femora and tibiae similar but the obscure mark on the tibiae 

 forms more nearl}^ a median band. Fore tarsi all rich brown, 

 middle tarsi black. Hind legs all black except base of femora a 

 little yellowish ; rich golden brown pubescence below hind tarsi. 

 Pubescence of legs weak, pale yellow on anterior legs and black 

 on hind pair. 



Wings. — Clear, iridescent; subcostal cell pale brownish yellow ; 

 halteres yellow.

N.B. — According to Verrall, species with distinct yellow spots 

 on the pleurae should not be included in Syrphus, yet it is difficult 

 to know where else to place the present species. The shoulder 

 spots are not continued as a yellow border to the thorax, and both 

 this character, the Syrphus-VikQ fades of the insect and width of 

 abdomen (relatively broader than such species as cinciiis and 

 cinctellus) and the distinct Syrphus-\\\ie markings of the abdomen, 

 all prevent it coming in Sphaerophoria. In its general appearance 

 it is still less like Mesogramma or Allograpta. From Xanthogramnia
