Black ; <? with the clyi3eus down the centre only, or 

 entirely, and the sides of the face, j^ellow ; the yellow 

 colour of the lateral spots somewhat encircling the 

 antennal cavities at the base ; anterior tibiae in front, 

 and posterior tibise and tarsi narrowly at the base, 

 yellow ; ? with a somewhat elongate triangular spot on 

 each side of the face, and a narrow basal ring on the 

 posterior tibiae, yellow. 



Head and thorax deeplj^ punctured, and with a line 

 scattered pubescence ; the surface between the punctures 

 dull, and seen under a strong power to be finely rugose ; 

 puncturation of the scutellum sparser and larger than 

 that of the mesothorax ; post-scutellum subrugose ; 

 metathorax longitudinally rugose. Wings hyaline. Abdo- 

 men shining ; basal segment impunctate or nearly so ; 

 following segments punctured, and in the S with a very 

 short black pubescence ; no white pubescence at the 

 apex of the 1st segment laterally in either sex ; ^ geni- 

 talia with the stipites widely rounded and somewhat 

 dilated at the apex ; sagittae as long as the stipites 

 or longer, narrow, converging at the apex. See pi. vii.,

 spot on each side of the prothorax, and a spot on each 

 tubercle, yellow ; extreme base of the tibiae and tarsi in 

 the <? yellow. 



Head and thorax punctured with a line short pube-
