S . — The basin of face in this and the two succeeding species, is 

 punctured and not well defined. The four basal joints of the antennae 

 are green. Color of body mostly blue-green. Punctures of prothorax 

 and first segment of tergum sepai'ated, of two sizes, with numerous 

 minute punctures between ; those of second segment smaller as they 

 approach the apex, where they are subobsolete and the surface polished ; 

 at the sides they are more abundant, with many larger shallow pits ; 

 on the third segment they are larger and more dense. The ante-apical 

 series of pits ends near the side angles. The series of foveolae crossing 

 the mesopleura longitudinally, are similar in this and 'pacifica^ viz. : a 

 distinct round deep pit near the abdomen ; the next two or three 

 toward the head are divided by subobsolete carinas. The mesopleura 

 is not sharply defined. Length .22 inch.

 9 . — The description of Say applies equally well to the above 

 which is probably the male of this. The ante-apical series of pits 

 extends nearly to the base of the segment; the foveola are longer 

 than wide, becoming round at the sides; apical margin of the segment 

 with indistinct cross striae ; the side angles of the margin are better 

 defined in some specimens than in others; between these and the base 

 of the segment, the margin shows another subangulation. In some 

 cases the basin of face shows a polished space down the middle. 

 Length .22 inch.

 Hah. — Massachusetts, Colorado, (Coll. Am. Ent. Soc.) 

 9 . — This is much larger than the other species, which it closely 

 resembles in form. The color is mostly green in specimens from 

 Colorado, mostly bluish in an individual from Massachusetts. There 

 are about three sizes of punctures on the tergum, with minute punc- 

 tures between, especially on the smooth subcarinate space down the 

 middle. The marginal angles at sides of third segment are well 

 defined, slightly prominent beyond the inner margin, the outer sides 

 sinuous, with a depression where there is an angulation in pacifica. 

 The line of foveolae crossing the mesopleura are not as large as in 

 Mlaris, and more numerous; the large pits beneath have fine cross 

 strige. Length .50 inch. 



Var. a. — 9 . — The angles at sides of third segment are produced 

 into strong teeth, the punctures of the segment more dense, the
