Aiigochlora quiriguensis , sp, n. 



$ . — Ag^reeinfif with A. nigrocyanea, Ckll., except in being 

 smaller (variable iti size, tlie smalbst hardly over 7 mm. 

 lon}^;) ; head much narrower; head and thorax ricli metallic 

 Prussian green, the niesothf>rax with a more or less evident 

 blaf'kish sliade in the middle. Wings dusky grey, without 

 the reddisli tint seen in nigrocijanea. 



($ . — Like that of A. n'igrocijanea, but smaller; wings 

 clearer and not reddish ; disc of mesothorax not so densely 

 punctured. 



Hah. Quirigua, Guatemala, 9 ? , 2 (? {W. P. Cockerell). 

 Four females and one male at flowers of Ipormea sid(BfoUa, 

 Feb. 10-12. 



Augochlora quiriguensis sid(efoU(B, var. n. 



$ . — Head and thorax black or blue-black, with green on 

 the inner orbits ; piothorax, lateral and posterior margins of 

 nietathorax, postscutellum and metaihorax, or the meta- 

 thorax largely black. 



(J. — Head and thorax bright blue ; punctures on disc of 

 mesothorax distinctly separated ; wiugs pale greyish, not 

 reddish. 



Hub. Quirigua, Guatemala, 4 ^,\ S (W. P. Cockerell). 

 Two females are from flowers of I/ionuMU sidmj'ulia, Feb. 12. 

 The male, whicli is possibly not correctly assigned to this 

 variety, is from flowers of plant no. 7. 



I confess to being puzzled by A. quiriguensis. It seems 

 too different from A nigrocyanta to be a diriiorphic form or 

 variety ; yet the males, if 1 have associated them correctly, 

 agree closely in structure, the only conspicuous diHerence 

 being in the e\idently spaced punctures of the mesothorax of 

 quiriguensis. Then, again, sidccfoiKB looks at first very 

 different from quiriguensis, but it is certainly no more than 

 a variety. 



A study of these insects in the field is necessary to deter- 

 mine their exact status. A. quiriguensis is very much like 

 the Brazilian A. fruncisca, Schrottky, but it is a more slender 

 insect, and the tarsi resemble the tibiae in colour (\u francisca 

 dull ferruginous, with their pubescence of the same colour). 



Halictus (Evylaus) hewetti, sp. n. 



? . — Length about 7 mm., anterior wing 4f . 

 Black, the pale pubescence faintly tinged with ochreous ;
