ORASEMA COLORADENSIS Wheeler 



Orasema coloradensis (Ashmead) Wheelee, Bull. Amer. Mus. Nat. Hist, vol. 23, 

 p. 12, 1907. 



Orasema coloradensis^ a manuscript name of Ashmead, was first 

 published by W. M. Wheeler, who gave a figure and a short description 

 of the species. The name should therefore be credited to Wheeler and 

 not to Ashmead. 



According to Wheeler, specimens were taken at Manitou, Broad- 

 moor, and Colorado Springs, Colo. In the U. S. National Museum 

 collection are three specimens from Colorado, one of which bears the 

 name label in Ashmead's handwriting, and this specimen had been 

 entered in the type catalog as the type of the species. It cannot be 

 the type, however, since it, as well as two other Colorado specimens in 

 the collection, named by Ashmead, was collected by C. F. Baker, and 

 there is no evidence to indicate that it was ever seen by Wheeler. 

 There are apparently no Wheeler collected specimens of the species in 

 the National Museum, hence no type material. The Baker specimens 

 are believed to be the same species, however, and the following descrip- 

 tive notes on the species are taken from them. 



This brilliantly metallic-green species with testaceous scape, tegulae, 

 tibiae, and tarsi is rather easily recognized because of the unusually 

 weakly sculptured dorsum of the thorax. The axillae dorsally, the 

 scapulae dorsally, the posterior portion of prescutum, and to a large 

 extent the dorsum of scutellum are smooth or only very weakly 

 sculptured, usually shining, and often highl}^ metallic green. The 

 prescutum anteriorly, scapulae laterally, axillae on the sides, and the 

 base and sides of scutellum are finely and irregularly rugulose. The 

 parapsidal grooves, sutures between axillae and scutellum, and the 

 transverse furrow on scutellum are deep and distinctly foveated. 



The female has the head nearly uniformly rugulose and highly me- 

 tallic green, wider than the thorax. The postocellar line is longer 

 than the ocellocular line, the latter about equal to twice the diameter of 

 a lateral ocellus. The malar space is a little shorter than the eye, 

 flattened but not depressed down the middle. The clypeus is broader 

 than long, its anterior margin nearly straight. The supraclypeal area
