is quadrate or a little broader than long, well defined, the clypeal su- 

 ture complete and the clypeal fovea rather broad and deep. The an- 

 tennal scape is subcylindrical, rather short and slightly thicker than 

 usual; the pedicel is about as long as broad, the ring joint is trans- 

 verse, the first funicle joint is about one and one-half times as long 

 as broad and the following joints of funicle are subquadrate. The 

 club is 3-jointed, no thicker than the funicle and somewhat longer 

 than the two preceding joints. The pronotum behind the head is 

 practically smooth, while laterally it is weakly rugulose. The pleura 

 are rugulosely sculptured but the mesosternum, posteriorly at least, is 

 polished. The propocleum is rather strongly rugulose, without cari- 

 nae but frequently with some more prominent rugae medially which 

 at times may suggest a median carina. The coxae are weakly sculp- 

 tured, almost smooth. The abdominal petiole is a little shorter than 

 the posterior coxae, about one and one-half times as long as broad 

 and rugosely sculptured. The gaster is smooth and polished. The 

 forewing is rather densely ciliated, sparsely but distinctly so basally, 

 the costal cell nearly uniformly ciliated. 



The male is like the female except that the funicle joints are usually 

 somewhat longer, the lateral ocelli are not quite twice their own 

 diameters from the eye margins, the abdominal petiole is a little longer 

 than the hindcoxae, approximately three times as long as broad, and 

 the gaster is much smaller than in the female. 



Remarks. — No information is available regarding the three speci- 

 mens already mentioned as having been identified by Ashmead. They 

 bear labels exactly similar to those used on all Baker's Colorado ma- 

 terial and reading "Colo. 799" and "Colo. 778." In Baker's note- 

 book entries under these numbers refer to Lepidoptera and Coleoptera 

 collected in Michigan and Ohio. It is impossible therefore to trace 

 the history of these specimens. 



Twenty-one additional specimens of the species found unidentified 

 in the Baker collection were all collected in the neighborhood of Fort 

 Collins, Colo., and 3 specimens from the same collection were taken 

 at Opelousas, La. Other specimens studied include : 1 taken on Bige- 

 lovia at Albuquerque, N. Mex., August 16, 1895, by T. D. A. Cockerell ; 

 1 from Wades and 2 from San Diego, Tex., taken by E. A. Schwarz ; 

 1 from Cimarron, Kans. ; 1 from Beloit, Iowa, collected by G. O. Hen- 

 derson, July 25, 1928 ; 46 swept by J. C. Bridwell from Stylosanthus 

 at Barcroft, Va., July 5, 1931; 6 taken at Bladensburg, Md. ; and 1 

 collected by Ashmead in eastern Florida. 



The specimens from the Eastern States are very slightly smaller 

 and not quite so brilliantly metallic as those from the Western, the 

 dorsum of the thorax usually appearing very slightly more distinctly 

 sculptured. At most these differences seem to be of not more than 

 varietal significance.
