nal segments, yellowish ; hind tibise striped with black above ; 



wings clear variegata. 



Clypeus (rarely maculated), dorsulum, Bcutellum, metanotum and 

 niiddle-segment (except latero-posterinr angles) black, in rare 

 cases only are these parts spotted, and then only to a slight degree; 

 last two or three dorsal abdominal segments black, sometimes the 

 fifth, or fifth and sixth spotted, in which case the spots are widely 

 separated ; hind tarsi not striped with black, wings a little dusky,

Texas and Kentucky (Handlirsch). I have received a 9 from 

 the Rev. G. Birkman, of Lee County, Texas. The S I have not 

 seen. Handlirsch is probably right in assuming that Cresson con- 

 fused ventralis, insidiatrix and capnoptera, in his "Hymenoptera 

 Texana."

Monedula parata Provancher, Add. Hym. Quebec, p. 416. 



California (Provancher): Los Angeles (Coquillett) ; Utah; 

 Nevada. The maculation of this species is a much richer yellow 

 than in ventralis, and the 9 , which has been heretofore unnoticed, 

 is very much like the S , and has a well developed pygidium.

Our most abundant and widely distributed species. It is reported 



from Canada (Provancher), and I have before me specimens from 



Massachusetts, New Jersey, Pennsylvania, Virginia, Georgia, Texas, 



Colorado, California, Oregon and other localities.
