Female. — Length about 10 mm.; brilKant shining blue-green, with 

 strong purple tints, especially on head and abdomen; head and 

 thorax densely punctured, the punctures on mesothorax strong; 

 pubescence short and thin, wliite on pleura, cheeks, and face (a 

 little black on supraclypeal area), black on vertex, mesathorax, and 

 scutellum, white on metathorax; head rather long, the clypeus 

 prominent, with large well-separated punctures, its apical margin 

 depressed in middle; mandibles black, strongly dentate, and with a 

 blue basal spot; labrum roughened, obscurely bituberculate; antennae 

 dark, scape not metallic; mesothorax a yellower green than the rest 

 of the insect, very brilliant; scutellum finely and closely punctured, 

 not bigibbous; area of metathorax with strong longitudinal strix, hut 

 these are complete only laterally; in the median area they extend less 

 than haljway to the jMsterior edge, the nonstriate part being minutely 

 roughened; posterior face of metathorax shining; tegulge with the 

 anterior half strongly metallic, the posterior rufopiceous; wings 

 hyaline, sHghtly dusky, but not dark, stigma dark ferruginous, 

 nervures dark fuscous; second submarginal cell large; first recurrent 

 nervure joining second transverso-cubital, but toward the inner side, 

 or just entering second submarginal; all the femora metallic, but 

 the tibiae and tarsi black; claws ferruginous; hind spur microscopically 

 serrate as in vl. huschi; abdomen broad, little hairy above, hind mar- 

 gins of segments not hlack, or at most a linear hardly noticeable edge; 

 ventral surface with long.yellowish-wliite hair, not mixed with black. 



Habitat. — Baracoa, Cuba, Aug., 1902 {Aug. Busck). The follow- 

 ing table separates the species of Augochlora known from Cuba : — 



Area of metathorax with the median third striate only at base: tibiie and tarsi not 



metallic; insect with strong purple tints cubana Cockerell 



Area of metathorax striate i^ractically all over 1 



1. Tibiae and tarsi not metallic; their pubescence black regina Smith 



Tibiae metallic, with pale or hoary pubescence 2 



2. Abdominal segments "beautifully margined with violaceous," the margins also 



depressed and impunctate (male) magnifica Cresson 



Abdomen ordinary 3 



3. Scape purplish-blue; head golden-green (female) prxclara Cresson 



Scape black (male) elegans Cresson 



I have never seen A. magnifica or prseclara. A. elegans I have 

 examined in the British Museum, the specimen being from Santo 

 Domingo. 



I have not seen A. claviventris Ashmead, from St. Vincent; Mr. 

 Rohwer tells me that it is not represented in the U. S. National 

 Museum. It will be readily known from the other West Indian 

 species by the claviform piceous-black abdomen of the male.
