the long basal joint green, the second and third joints green above. 

 Thorax very slightly narrowed in front ; closely, uniformly and coarsely 

 punctured, dark green above slightly tinged with bluish, the sides 

 brighter green, the prothorax with a slight longitudinal impression on 

 the disk ; mesothorax slightly tinged with dark obscure blue, the disk 

 with two well impressed longitudinal lines ; metathorax azure-blue at 

 the extreme tip, the posterior angles large, flattened, divergent, and 

 acute at tip; tegulae bright green. Wings subhyaline, slightly tinged 

 with fuscous especially towards the base, with a slight purple iride- 

 scence ; nervures blackish. Legs green, pubescent, tarsi blackish. 

 Abdomen broad and robust, densely and deeply punctured, the punc- 

 tures becoming finer towards the sides and apex of the segments, and 

 the interstices between the punctures finely but distinctly punctured ; 

 dorsal surface of the first and second segments brilliant azure-blue, 

 shading into metallic green on the sides, and in certain lights the apical 

 margins are slightly greenish ; third segment less coarsely punctured, 

 almost entirely bright metallic-green, tinged with blue at the base, 

 more conspicuous in certain lights ; before the apex of this segment 

 there is a transverse row of deep punctures, the apical margin pube- 

 scent, with six short, acute, equidistant teeth, the lateral ones not so 

 acute as the others; venter bright metallic green, polished. Length 

 5 lines; expanse of wings 62 lines. 



Collection. — Dr. J. Gundlach. One specimen. 



Closely allied to C. insularis, but besides the differences enumerated 

 above, the form is more robust, the excavation behind the antennae is 

 bright golden-green, and the face about the insertion of the antennae is 

 not densely pilose as in insularis ; the second and third joints of the 

 antennae are tinged with green, while in insularis they are entirely 

 blackish. It may be easily distinguished by the much denser puncta- 

 tion of the abdomen, which in insularis has a smoother appearance. 



Chrysis subviridis. n. sp. 



Obscure green, brighter beneath; mesothorax obscure; abdomen deep blue, 

 strongly tinged with purple, the apical margins and sides of the segments tinged 

 with green : apical margin of third segment with six long acute teeth ; wings 

 fusco-hyaline. 



Male. — Head obscure green, grossly punctured, slightly pubescent; 

 a twice angular transverse carina on the front below the ocelli ; the 

 excavation behind the antennae finely rugose and bright metallic-green; 

 sides of the face pilose ; mandibles, except base, blackish, the long basal 

 joint green. Thorax obscure green above, brighter on the sides and 

 beneath, densely and coarsely punctured; mesothorax obscure dusky,
