58 Mr. T. D. A. Cockerell — VescrijAions and 



Augochlora nigrocyanea, Cockerell. 



Quiri.sna, Guatemala, 21 ? {W. P. Cockerell^. Six 

 (Feb. 12) at Ipomoea sidafu/ia ; two (Feb. 20) at Ipomoea 

 quiiiqucfulia ; two at Zexnu-nia virynlta. A male was taken 

 at Iponvxa sidafulia, Feb, 10. It has the head and thorax 

 more ^reen than blue, the colour bi'illiaut ; clypeus stroiijily 

 produced, its apical margin, the labrum, and mandibles 

 testaceous; flagellum ferruginous beneath ; wings reddish. 

 The mesothoracic punctures are considerably lai'ger than in 

 the female, but extremely dense. 



Augochlora seminigra, Cockerell. 



Quirigua, Guatemala, 16 c?, 19 ? [W. P. Cockerell). 



The females mostly show more green on the abdomen than 

 the type. The male is new ; it is like the female except for 

 the usual sexual cliaracters ; the lower edge of clypeus is 

 broadly cream-colour. Thirteen females were resting on a 

 branch of Solanum. Two males and four females were at 

 flowers of Zexmenia rirgulta ; two females were at flowers of 

 Pontederia cor data, February 11. 



Augochlora urania, Smith, var. a. 



$ . — Middle of mandibles broadly ferruginous ; wings 

 dusky, rather greyish than reddish. 



Giialan, Guatemala, Feb. 22, 1 $ [W. P. Cockerell); 

 Quirigua, Guatemala, 7 ? (IV. P. Cockerell). Of the 

 Quirigua specimens two are from yellow flowers of a species 

 of Corapositae ; three (Feb. 20) are from fpomcea quinquefGlia 

 flow-ers ; one (Feb. 20) is from Ipomoea sidfjefolia. 



A. urania was described from Brazil, and there is reason 

 to suspect that actual comparison with Smith's type might 

 show the Guatemalan species to be distinct. There is, 

 however, practical agreement with Smith's description, and if 

 our bee is not a local variety of urania, it is at least very 

 closely allied. At first sight A. urania, var. a, may easily be 

 confused with A. serninigra, also common at Quirigua. On 

 closer inspection it is readily separated by its broader form 

 and coarsely granular mesothorax. It is, in fact, nearer to 

 A. azteculu, Ckll., which it very greatly resembles ; but 

 aztecula has the abdomen entirely green and the anterior 

 tibiae clear ferruginous with a dark patch behind. 



The type of A. urania is in the W. W. Saunders collection, 

 presumably at Oxford, so 1 did not see it when examining 

 Smith's species at the British Museum.
