This variety should be attached to race tricolor rather than to race 

 ferruginea. The dorsum of the metanotum is like that of tricolor, and 

 moreover, except in colour and the shape of the 1st node, the $ $ of 

 the two are indistinguishable.

$ . 4 - 2-5 mm. Head and thorax varying from pale reddish-brown 

 to dark chestnut (a reddish burnt umber). Petiole darker than the 

 thorax, abdomen dark brown or brownish-black, a trifle paler 

 at the base but not yellow as in race tricolor. Legs dark brown, tarsi 

 more ferruginous, antennae reddish-brown, the club and scape usually 

 darker. The fundamental sculpture of the thorax is a little stronger, 

 and the reticulations wider apart than in tricolor. The sides of the 

 mesonotum are not so sharply margined as in that race, and the 

 epinotal spines are considerably stouter, especially at the base, and 

 also a little shorter or not more than twice as long as their basal 

 width. The median groove on the second node is shallower than in 

 tricolor, and the posterior margin of the discs of the node less sharp. 

 Otherwise like race tricolor. 



? . 8-9 - 6 mm. (hitherto undescribed ?). Head dark chestnut red, 

 usually paler in front. Thorax dark brown, the epinotum and petiole 

 less dark. Abdomen black, legs and antennae dark brown. The 

 apex of the scutellum is narrower and more angular than in tricolor, 

 and the brow of the declivity of the epinotum is less abrupt. The 

 2nd node is more distinctly divided into two discs, the median 

 groove being fairly deep behind. Otherwise like tricolor. Wings 

 hyaline, nervures and stigma pale yellow. 



<J . 4 mm. Dark brown ; the head black, the paraptera, metanotum, 

 dorsum and declivity of epinotum brownish-yellow or yellowish-brown. 

 Elagellum pale dirty ochreous ; tarsi pale brown ; wings hyaline, 

 nervures and stigma brownish-yellow. Pilosity pale yellow, short and 

 scanty, exserted on the scutellum and petiole, more or less decumbent 

 elsewhere. Flagellum with abundant and exserted pubescence. Head
