Clirysis Meta n. sp. — Varies from emerald-green with brassy reflections, 

 and slight golden reflections on the abdomen to golden and green with strong cu- 

 preous reflections, deepest on the abdomen ; head and thorax closely and equally 

 punctured, finest on the head; basin of face broadly smooth; abdomen with the 

 punctures of the first and second segments somewhat separated but evenly dis- 

 tributed, with finer punctures scattered among the others; specimens with the 

 abdomen deep cupreous have the sutures, when exposed, black, and a patch on 

 basal half of dorsum of second segment black, shading to green, the punctures 

 within it green; third segment with the punctures larger, a little confluent ; apical 

 margin beyond the pits in all the specimens black; pits rather large or medium, 

 distinct or confluent, rounded or oval, contained in a shallow groove, which ends 

 midway on the lateral margin ; wings hyaline, very slightly infumated at the base 

 of the radial cell ; 6-7 mm. long. % 9 . 



Montana ; twelve specimens. A very beautiful and distinct species. 



Chrysis dorKalis n. sp. — From dark blue, purple and green, to emerald- 

 green and no purple: head and thorax closely and equally punctured ; basin of

 the dorsum of each sej^meiit of a deeper and duller color, black §n the green speci- 

 mens, purplish black in the blue; pits medium, or a little large, round, separated, 

 contained in a shallow groove, which ends midway on the lateral margin; some 

 .specimens differ from the figure (plate 9) by having the median teeth as far apart 

 as the median and outer teeth, and somewhat pointed ; wings hyaline, infumated 

 on the basal half, in ane specimen fusco-flavescent ; 6-7 mm. long.

 punctured on each side; abdomen with the punctures very little separated, almost 

 as close as on the thorax, larger on the sides and towards the apex of third seg- 

 ment; pits large, shallow, slightly separated, forming a large, distinct, though 

 shallow groove, which extends midway on the lateral margin ; wings almost

Chrysis Frey-CJessneri Gribodo, Ann. Mus. Genov. xiv, p. .333, 1879. 

 Three specimens from New York, Texas and Washington Territory.' 

 Gribodo's description is as follows : 



"Of moderate size, slender, cylindrical, not very bright, obscurely green; head 

 and thorax very densely and irregularly punctured and subcoriaceous (scutellum 

 and postscutellum punctured and reticulated); abdomen closely and regularly 

 punctured; head, viewed in front, rounded, quadrate; facial cavity large, not 

 deep, margined above and at the sides; postscutellum rather flat and sloping; ab- 

 domen nearly as broad at apex as at base, a little longer than head and thorax 

 together; third segment entirely uniformly convex on all sides, i.e. the anteapical 

 series entirely wanting, and the anal area not immersed, but on the contrary 

 forming in the same position a very large and deep erose fovea, interrupted in the ,
