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 ?

swelled. First abd. segment rather wide posteriorly, 

 although still not funnel-shaped.
