556 Mr. T. D. A. Cockerel! — Descriptions and 



Xijlocopa fimbriata, Fiibr., var. motaguensis, uov. 



A female from Gualan, Guatemala, Feb. 1912 [W. P. 

 Cockerel/), has the wirifi^s a fine blue-^reen, bluer in the 

 middle, and the broadly interrupted transverse frontal carina 

 has its divisions longer and larger than in a specimen 

 collected by W. W. Brown, Jun., at Saboga Island, Panama. 

 The Panama insect also has the wings quite differently 

 coloured, wdtli no bright tints, but washed with obscure 

 goldeir green, the apical field a little purplish. Lepeletier 

 described X. cornuta, Lep., usually considered a synoirym o£ 

 frontalis, as having the frontal keel interrupted, whereas 

 ■fimbriata was said to have it entire. Both came from 

 Cayenne. According to the characters given by Lepeletier, 

 both the Guatemala and Panama insects should be cornuta. 

 Perez describes great colour-variation in the wings of X.fitn- 

 hriata. The colour of the wings of cornuta, as described by 

 Lepeletier, acconis sufficiently with the Panama insect. If 

 Lepeletier^s diagnosis of fimbriata is correct it is probable 

 that X. cornuta is a good species, and the insect now described 

 will then stand as X. cornuta motaguensis. 



Agapostenion nasutus gualanicus, var. n. 



cJ. — Metathorax usually very blue; anterior and middle 

 femora with much black or fuscous on the basal half; hind 

 femora entirely black behind; hind tibiae largely pale 

 brownish ; black abdominal bands very broad. 



Hab. Gualan, Guatemala ((F. P. CocA'ere//, 2) ; four males. 



This appears to be a dimorphic form oi A. nasntus, Sni., 

 the typical form of which is abundant at Gualan. The 

 broader abdominal bands and darker legs give it a distinct 

 appearance. 



1 cannot separate the Gualan females into two lots. 



Ceratina amabilis rhodochrysea, var. n. 



$ ^ . — Abdomen not so purple, more salmon-red, the hind 

 margins of tlie segments brouflly sufi'uscd with gold: head 

 and thorax a bluer green. 



cJ . — Vertex dark purple-blue ; face-markings consisting 

 of a very large and thick reversed T on clypeus, and small 

 triangular lateral marks (the female has no lateral face- 

 marks, the lateral spots being clypeal) ; greater part of 

 labrum and a small spot on each mandible cream-colour ; 

 middle and posterior femora angled below, the miildle very 

 obtusely; apex of abdomen with the sides convex and the
