and two on the face on each side of the clypeus touching the mar- 

 gin of the eyes, yellow ; an elongate yellow stripe behind the eyes ; 

 antennae, labrum and mandibles black. Thorax, the anterior 

 femora at their apex above, and all the tibiae at their base yellow ; 

 the posterior tibiae have a short spine near their base exteriorly ; 

 the posterior tibiae and all the tarsi densely covered with cine- 

 reous pubescence, the claws and apical joints of the tarsi ferru- 

 ginous ; the metathorax on each side covered with white pubes- 

 cence ; abdomen, the margins of the three basal segments 

 depressed, smooth and shining, the three apical ones rugose.

Maxillary palpi six-jointed, the basal joint thickest, nearly as 

 long as the two following, the three apical ones minute, the labial 

 palpi four-jointed, the two basal ones elongate, the apical ones 

 minute ; the superior wings having one marginal and two sub- 

 marginal cells. 



In the ' Encyclopedic Methodique,' and also in St. Fargeau's 

 ' Hymenoptera,' the number of joints in the maxillary palpi is 

 incorrectly given ; it has therefore been necessary to give the 

 above short correction.

The male closely resembles the female, but has the clypeus 

 entirely yellow ; the abdomen is black at its extreme base as 

 well as the four apical segments, except the base of the fourth ;

Female. Length 3J lines. Black, a narrow yellow stripe 

 along the inner margins of the eyes, and another down the middle 

 of the clypeus, which is produced and rounded at its anterior 

 margin ; the face on each side above the clypeus depressed, as in 

 the genus Ceratina, the antennae inserted in the depressions, 

 between which is a raised carina running from the clypeus to the
