joins second t. c. ; in A. fcronia Sm. it enters the base of third s. m. 

 The wings are conspicuously dusky. 



Two males from Guayaquil, May-June, 1913 (Bnies), are referred 

 here, in spite of the fact that they have the punctures of mesothorax , 

 and scutcllum less crowded and more distinct, the stri?e at base of 

 metathorax coarser and less numerous, and the tegute reddish instead 

 of piceous. I should have thought them to belong to a distinct though 

 very closely allied species, had I not previously found somewhat 

 similar sexual ditYerences in A. quirigucusis Ckll. The labrum, an- 

 terior edge of clypeus and nearly all of mandibles are cream-color. 

 The tarsi are dark. 



Augochlora vesta Smith. 



Guayaquil (v. Biichzvald; Alfken coll. 19, 20). 



After I had determined this as z'esta, I found that one of the 

 specimens carried a label with the same determination made by 

 Alfken. These specimens are true A. vesta, with golden-green head 

 and thorax. A female taken by Brues at Guayaquil, May-June, 1913, 

 has the head and thorax blue-green, and the first abdominal segment 

 largely brassy though with red tints, but green at base and sides. I 

 cannot separate this from a female from Villa Encarnacion, Paraguay, 

 sent by Schrottky as A. vesta van cupreola Ckll. A cotype of the 

 real cupreola, from Chapada, is larger and has the punctures on pos- 

 terior middle of mesothorax widely separated, and is obviously a 

 different species. It seems probable that the form of A. vesta repre- 

 sented by the Brues and Schrottky specimens just cited should be 

 called var. tcrpsichore (Holmberg). Schrottky treats A. tcrpsichore 

 as a synonym of A. cupreola. 



Augochlora thalia Smith. 



Guayaquil, May-June, 1913, 3 males (Brues). 



These specimens do not appear to differ from the Brazilian A. 

 thalia. 



Augochlora cladopyga new species. 



Male. — Length about 5^ mm., anterior wing 4; brassy green, with thin 

 white pubescence; head broad, eyes very deeply emarginate ; front minutely 

 granular, dull ; face shining emerald green, contrasting with the golden-green 

 clypeus, the lower margin of which is broadly very pale yellow; mandibles
