c?. Leugtb 10 mm. 



General coloar oramje ; ahdomen (.leep dull oraiir/e, lulth meUdlic 

 hi'oiini posterior borders to the segments, flat, not contracted hasally, 

 hut e,vj)andinr) regularly to the end of the fourth segment : wings 

 suffused ivith broivn, sUglitly jpaler towards the tips; ahdce of 

 full size. 



Face and cheelcs pale yellow, thiuly clothed ^ith pale yellow 

 pile ; the face receding, ^ith a very small tubercle. Front orange 

 poUinose, with a bro\^n median stripe from the angle of the eyes 

 to the n])])er margin of the very slight antenuiferous jn'ojection ; 

 the latter ])ale orange in front, shining, Milh a black dot abo\e 

 the antenna^ ; the front clothed \\'it\\ broun pile. Aiifenme orange, 

 short, third joint ronnded at the tip, with the n]iper margin brown ; 

 arista brown, yellow isli at the base ; vertical triangle bronze, black 

 at the apex, long, narrow ; ocelli remote from the vertex. Dorsum 

 of thorax metallic orange, somewhat iridescent, not poUinose, 

 with three narrow faint brown stripes (one median and one 

 on either side of it), which do not reach more than halfway : 

 lileurcii metallic yellow; scMif(^Z?w)» dull saifron-yellow. Ahdomen: 

 first segment brownish orange ; second segment with a metallic 

 transverse band on the anterior as well as the posterior fourth ; 

 this segment is somewhat shining, especially in the median 

 line ; on the third segment the metallic brown transverse band 

 on the posterior fonrth expands somewhat towards the sides, and 

 there is a semi-obsolete faint browji median stripe, extending 

 from the anterior margin to the posterior border ; on the foiu'th 

 segment the posterior band is only about half the width oi' 

 that on the third, but it ex])ands into a median triangle, whidi 

 is connected by a faint brown stri])e with the anterior margiji, 

 and also into a quadrate area on each side, which occupies rather 

 more than half the length of the segment ; the median stripe is 

 somewhat cla^'ate at its anterior extremity, and this is also the 

 case with the similar stripe on the third segment ; the fifth segment 

 is whollj' shining, and the brown portion is abont equal to 

 the orange in area ; the posterior border is, however, much 

 narrower, while the median stripe is broader and more sharply 

 defined than on the previous segments, and that which corresponds 

 to the brown lateral quadrate areas on the fourth segment is here 

 represented by an ovate mark on each side, extending nearly to 

 the anterior margin and situated nearer the middle Hue, so that 

 the lateral margin of the segment as far as the posterior border is 

 orange ; the orange portion of the fifth segment on each side of 

 the median stripe is therefore deeply indented by a brown notch : 

 genitalia brown at the tip : with the exception of a tuft of pale 

 yellow hairs on each side of the first segment, the pile on the 

 abdomen is black, appressed, and very short and sparse, though it 

 is somewhat longer on the fifth segment. Legs yellow ; posterior 

 pair deeper orange, but without bands. Third longitudinal vein
