Diagnosis: Species of group ii with typical Ogcodes pattern (pi. 5, 

 fig. 29); vein Mj, although usually completel}^ absent, is sometimes 

 faintly present basally (pi. 4, fig. 18); thorax black, sometimes females 

 with brown markings on humerus, scutellum, postalar callus, and 

 pleurites; legs vary from dark to light brown with only coxae black, 

 tibiae usually dark brown; male genitalia as shown in plate 11, figure 

 78, plate 12, figure 94 (ejaculatory apodeme), and plate 11, figure 73 

 (aedeagus). 



Type locality: Texas (cf , Belfrage, MCZ). 



Distribution: This is a widespread species ranging from southern 

 Mexico to Canada. It is apparently adapted primaril}^ to the So- 

 noran and Transition Zones, and is more common at the lower eleva- 

 tions (see text fig. 5). 



Recorded distribution: About 200 specimens have been listed 

 from the following areas: Alberta, Arkansas, California, Colorado, 

 Illinois, Indiana, Kansas, Maine, Massachusetts, Michigan, Missouri, 

 Mexico (Morelos), Montana, New Jersey, New York, Ohio, Oklahoma, 

 Ontario, Texas, Utah, Virginia, Washington D.C., West Virginia, and 

 Wyoming. All records west of the Rocky Mountains were given as 

 alhicinctus Cole. 



New distribution records: (157 specimens, 86 cf, 719.) Because 

 of the large number of recorded specimens, only those new ones of 

 special importance and new state records are cited here.
