SCOLIA. 225 



In one specimen, from Costa Rica, the yellow is reduced to two marks on the second 

 and third segments ; in another, from Jalisco, Mexico, the only yellow to be seen is on 

 the second abdominal segment, in the form of two yellow marks ; and, lastly, we have 

 two examples without any yellow whatever. In some specimens the marks are almost 

 white, not yellow. 



Our male examples do not show much variation ; they have either two yellow marks 

 on the first and second abdominal segments, or two on the second segment only.
