the eye-margins ; the epistoma is a little hollovved below the antennæ, 

 with a very low central knob and below it slightly retreating, the 

 lower part is thus not protruding but it is considerably descending. 

 Occiput blackish, grey pruinose, the hairs whitish, but above also long, 

 black hairs. Antennæ brown or reddish 

 brown, arista darker towards the apex. 

 Thorax black, shining, somewhat æneous 

 on the front part, a little greyish pruinose 

 on and inwards to the humeri ; it is clothed 

 with moderately long and not specially 

 dense hairs which are pale yellow in front, 

 black behind, but whitish in front of scutel- 

 lum, the black hairs thus forming a cross- 

 band. Scutellum black with white hairs.

 generally some black hairs below the wing- 



root. Abdomen widening from the base towards the middle and then 

 narrowing towards the apex, about the middle wider than thorax; it 

 is black and red, somewhat shining; the two first segments black, the 

 rest red ; the third segment varies somewhat in colour, it has gener- 

 ally a black middle spot near the front margin, then there may more- 

 over be a spot at each side near the hind margin but these latter 

 spots rather irregular; the spots may be enlarged and confluent so 

 that the hind part and the middle of the segment are black, the red 

 colour forming only two large basal corner spots and again each of 

 these may have a black spot at the front margin; abdomen is clothed 

 with short hairs; they are black on second segment except on two 

 inwardly triangular patches at the basal corners where they are white, 

 and they are long at the corners ; the third and fourth segments have 

 reddish hairs, but on the third are black hairs on the hind part and 

 along the middle (the parts which are sometimes black); genitalia red. 

 Venter reddish witli the first and sometimes also second segment 

 blackish; the hairs are sparse, pale and not long. Legs black, the 

 apex of femora and the base and apex of tibiæ yellow, the base the 

 most broadly ; tarsi yellow with the two last joints black. Legs short- 

 haired, the hairs only a little longer behind the anterior femora but 

 hind femora quite short-haired ; the hairs are black but more or less 

 yellow on the anterior tibiæ, and whitish behind middle femora to- 

 wards above; the posterior tarsi are distinctly black-spinulose below. 

 Wings brownish grey tinged with a faint middle fascia and the medial 

 cross-vein a little seamed. Squamulæ milky white with white fringes. 

 Balteres pale yellow.
