238 S. FRANK AARON. 



Kentucky, Georgia, Florida ; four specimens. In the form of the 

 margins and in the general shape of the third segment the species is 

 allied to C. fasciata Fabr., from Mexico, but differs by having distinct 

 pits contained in a deep groove. The abdomen of this species is con- 

 siderably longer than the head and thorax combined. 



Chrysis tripartita n. sp.— Head and thorax, with the nietathorax and 

 abdomen, emerald-green with very slight dull blue and darker green reflections; 

 mesothorax deep blue with slight dull purple reflections; basin of face very nar- 

 rowly striated ; closely and about equally punctured all over, on the abdomen the 

 punctures a little more separated ; posterior surface of the postscutellum as viewed 

 laterally not evenly rounded, but angled and almost projecting; pits medium, 

 rounded, distinct, in a shallow groove that ends about midway on the lateral mar- 

 gin, or a little nearer the base of segment; apical teeth short, broad, round at the 

 apices, the median teeth somewhat longer than the outer, much closer together 

 and separated by a deeper emargination than the median and outer teeth; lateral 

 margins about straight; wings infuscated, paler on the outer margin; 10.5 mm. 

 long. 9 . 



Arizona ; one specimen. The position of the apical teeth resembles 

 that of C. peluciduld, plate ix, fig. 58. The deep blue mesothorax 

 divides the anterior and posterior portions of the insect, which are bright 

 green, into three parts of color ; a very odd character. 



Chryiiis propria n. sp. — Green with slight blue reflections, some specimens 

 with distinct brassy reflections; basin of face striateil ; head and thorax closely 

 and evenly punctured ; abdomen with the punctures varying in different speci- 

 mens, in some close and equally distributed, in others separated and with finer 

 punctures scattered between ; punctures close on the third segment in all the 

 specimens, in some subconfluent; ])its medium, in one specimen a little large, dis- 

 tinct, rounded, within luteous, semi-transparent when held against the light; 

 groove shallow and with the pits ending on the lateral margin near the base of 

 the segment; wings almost clear hyaline, a little infumated, in some specimens 

 the radial cell is infuscated; 6-7.5 mm. % 9- 



Montana, California, Colorado and Arizona; eight specimens.

 Chrysis pulcherrima Cresson, loc. cit. 311. 



Eleven specimens ; the localities are Washington Territory, California, 

 Colorado, Arizona and Texas. The varieties (all of which we have in 

 the collection together with the gradational forms) are shown in Mr. 

 Cresson's excellent descriptions. We have not one of the three types in 

 the collection ; however, the descriptions agree perfectly. The median 

 space of the mesothorax in prasinua being deep blue and black is very 

 odd, but it cannot be considered a constant or important character. Our 

 specimen of prasinus proper is from Arizona, not from Colorado. One 

 specimen of lauta, from Colorado, is emerald-green with very bright
