from the tip (Cresson says "at the tip") on one side; on the other 

 side the second intercubitus is missing. The abdomen is entirely 

 black. The species is extremely like (J. moesta (Cresson), but the 

 character of the front at once separates it. 



AUGOCHLORA QUIRIGUENSIS SIDAEFOLIAE Cockerell. 



One female. New to Mexico; described from Guatemala. The 

 specimen differs slightly from the type, in having the area of meta- 

 thorax more finely sculptured, and strongly flushed with purple. 

 The resemblance of this species to A. nigrocyanea Cockerell is only 

 superficial, as I find on examining Guatemalan specimens of the 

 latter, that it belongs to the subgenus O dontochlora, the female 

 having a large spine on the first ventral abdominal segment. 



AUGOCHLORA (ODONTOCHLORA) AZTECA (Vachal). 



Female. — Length about 8.5 mm.; bright blue-green; legs black, 

 with the anterior femora green behind, and the middle ones some- 

 times green beneath ; antennae black, the flagellum obscurely brown 

 beneath; mandibles black; head ordinary; clypeus shining, with 

 large punctures; supraclypeal area rough, but distinctly punctured; 

 front and vertex very densely rugosopunctate ; anterior angles of 

 prothorax very wide; tubercles sharp and prominent; mesothorax 

 and scutellum densely and finely punctured; area of metathorax 

 large, entirely covered with fine radiating striae ; mesopleura rugose ; 

 tegulae dark brown, with hyaline margin anteriorly ; wings hyaline, 

 apical margin broadly faintly dusky ; stigma brown ; nervures dark ; 

 first recurrent joining second submarginal cell a little before end; 

 legs with white hair, pale yellowish on inner side of tarsi ; hind spur 

 microscopically serrulate ; abdomen brilliant green, delicately silvery 

 pruinose, hind margins of segments narrowly black, and apical seg- 

 ment entirely black ; punctures of abdomen very fine and delicate ; 

 venter black, the first segment green, and having a long sharp spine. 



Two females ; Victoria, Mexico, March 16. 



In Schrottky's table of Odontochlora this runs nearest to ^4. phoe- 

 monoe Schrottky, which it much resembles, differing by the clearer 

 wings and more distinctly (though very finely) punctured abdomen. 

 It is easily known from A. rrmllen Cockerell by the longer area of 

 metathorax and much more delicately punctured abdomen. From 

 A. IjogoteTisis (Vachal) it is easily known by the basal area of meta- 

 thorax being covered with striae. From .1. sporas (Vachal) by the 

 densely punctured middle of mesothorax. Some of the punctures 

 on the clypeus are confluent, and the apical striae of the area of 

 metathorax spread out to become more or less transverse, so that 

 the characters are precisely those designated for A. azteca (Vachal),
