Observation. — Unfortunately, I do not find this species again 

 in the collection of De Romand, in which I described it. As the 

 insects of this collection were very negligently labelled, it may 

 not be an American species ? 



2. Maxillary palpi moderately slender, the first joint rather 



swelled. First abd. segment rather fuide posteriorly, 

 although still not funnel-shaped.
