according to the descriptions, have the first r. n. meeting the second 

 t. c. ; the latter genus has an extremely long tongue. 



Species which have been referred to Augochlora differ in venation, 

 as follows : 



(1) First r. n. entering middle (or near) of second s. m. : Corynura briseis (Sm.). 



(2) First r. n. entering end (or near) of second s. m. 



(a) Halictus nanus (Sm.) and H. aspasia (Sm.). 



(b) Corynura titania (Sm.). 



(c) Sericei, with only three spines on hind spur: A.chloris and aurora. 



(d) Oxystoglossi: A. alcoyne. 



(3) First r. n. meeting second t. c. (typical venation of Augochlora). 



(a) Group uncertain : A. festiraga. 



(b) Sericei or Oxystoglossi ( J unknown): A. daphnis. 



(c) Sericei : A. chryseis and deidamia. 



(d) Vibrissati : A. atropos, diversipennis, calypso, paphia, viridana, fiam- 



mea, and n. sp. 



(4) First r. n. entering beginning of third s. m. 



(a) Vibrissati: A. Iseta and fervida. 



(b) Sericei: A. refulgens. 



(c) Oxystoglossi: A. feronia. 



These characters of the venation are not always to be relied upon, 

 as variation was noticed in A. radians and vesta. At the same time, 

 the number of Vibrissati in the third group must be considered 

 significant. 



(A) Vibrissati. 

 Augochlora berenice Sm. 9 (T.). 



Hind spur with five long teeth ; abdomen with much purple lus- 

 tre ; scutellum closely punctured, the punctures of one size. In my 

 Phil. Acad., 1900, paper it runs to the group of monochroa, etc.; it 

 agrees with the description of monochroa, except that the sides of 

 metathorax near the truncation are densely covered with punctures. 

 From heterochroa it is distinguished by the scutellum. My supposed 

 A. berenice from Brazil (t. c, p. 357) is not that species; it should 

 be described in detail, and given a name. It is now in the Carnegie 

 Museum at Pittsburg. 

 Augochlora Iseta Sm. ? (T.). 



Ega. A small species; first r. n. joining base of third s. m.; hind 

 spur with four or five long spines; abdomen broad and convex, 

 yellowish green ; segments one and two delicately ciliate, but the 

 cilia largely concealed by the general hoariness ; anterior tibiae a 

 beautiful golden green.
