One specimen (the type; from Colorado. It is emerald-gT-een with 

 some brassy reflections ; punctures about equal all over, dense on the 

 head and prothorax, less dense on the metathorax ; a little separated on 

 the first and second segments of the abdomen, very dense and indistinct 

 on the third segment. The apex of the third segment contains two dis- 

 tinct teeth, separated by a rounded emargination, and on each side of 

 these teeth is a broader sinuation separating the distinct lateral angles 

 from the apical teeth. This is, though less fully developed, the exact 

 pattern of the normal -i-dentate species ; pits small, rounded, rather close, 

 contained in a shallow groove ; deeper laterally ; 6 mm. long. The 

 specimen is a $ . ^

 Before me are three specimens, one of which is Provancher's type 

 from Canada, the others from Maine and Canada ; the head and thorax 

 in the two Canadian specimens blue with much green and purple, the 

 Maine specimen with the predominating color green, with some blue and 

 purple reflections. In all densely punctured, finest on the head ; basin 

 of face broadly smooth ; abdomen in the Canadian specimens cupreous 

 and golden, with brilliant emerald-green reflections in certain lights ; in 

 the Maine specimen cupreous with deep scarlet or ruby reflections, almost 

 entirely ruby on the dorsum, with green reflections only at the base of 

 first segment and on the apical margin beyond the pits ; abdominal punc- 

 tures on first and second segments equal, close, very little separated, be- 

 coming irregular laterally, and confluent and irregular on the third seg- 

 ment ; pits medium, rounded, subequidistant, contained in a shallow 

 groove ending midway on the lateral margin ; lateral angles and apical 

 teeth as in scitula ; 7-7.5 mm. long. All females. 



V, — Apical margin of abdomen quadr (dentate. 



Prothorax much shorter than the head (plate x, fig. 88). 



As seen from the side the lateral margins of third segment are bisinuate, slightly 

 near the middle and distinctly just before the outer teeth. 



Emerald-green, golden and cupreous 9Ieta. 



From dark blue and jjurple to emerald-green, with nothing more than brassy 

 reflections.
