yellow. The abdonion is paler on the basal seg-mcnts than on 

 the a])ieal ones, but the former have darker lateral infusca- 

 tions. 



The antennae do not pi-esent anv sti-ikino- charaeter, the 

 first, funiele joint beini>' mneh longer than the second, the second 

 fully twice as long- as its greatest width. The abdomen is long 

 and pointed at the apex, not twice as long as the thorax, but 

 more than one and a half times as long; the ovipositor sheath 

 in the nni(pie exam])le is subexserted and ])lack or nearly so. 



The male which I refer to this species dirt'ers rather remark- 

 ably from the female, in liaving the hind part of the mesonotnm 

 clear yellow and apparently not metallic. The whitish basal 

 portion of the abdomen bears a pair of blackish spots on each 

 side. The antennal characters do not differ much from those 

 of other s])ecies, the fourth funi(de joint being evidently wider 

 and slightly shorter than the second. The head is yellow, nn- 

 less discolored. Leniith 1.5 mm.

Female entirely dark, the thorax metallic green, the abdo- 

 men dark brown or black, less consi)icuously metallic than the 

 thorax and like the head becoming paler in balsam preparations. 

 The legs and antennae are more or less infuscate or smoky. 



The pedicel, second and third funiele joints do not differ 

 much in length, the first funiele joint (not counting the ring 

 joints) is very long, about one and a half times the length of 

 the second or third, the clnb is as long as the two preceding to- 

 gether, its apical joint being much longer than the basal. Thorax 

 with very distinct longitudinal rugulosity, the scutellar grooves 

 very distinct. Abdomen elongate, when fully extended longer 

 thaii the head and tliorax together. Length 1 — 1.2 mm.
