ones on the front border, adjoining tliose on the prothorax, a 

 longitudinal one between, then two slightly oval ones near the 

 middle, and a large irregular spot behind on each side, projecting a 

 branch forward within the very large black tegulse ; scutellum 

 black, strongly excavated iu the middle ; abdomen with the first 

 segment blue, a narrow longitudinal line, the greater part of the 

 hind border, and a long transverse spot contiguous to it black ; the 

 remaining segments of the abdomen are black, with a wide blue 

 stripe sloping slightly upwards on each side ; legs black, all the 

 tibiae with a wide blue stripe on the outside ; wings dark purphsh 

 brown. (2128, Maroe.) 



Allied to G. nitidula, Fabr., a species common in Amboina, Aus- 

 tralia, &c., but apparently distinct. 



Xylocopa forbesii, sp. n. 



Long. corp. 10 lin. 



Male. Thickly clothed above with olive-green pubescence, as in the 

 male of X. cestuans, Linn., or of X. hryorian, Fabr. ; antennae black 

 above and fulvous beneath, the hairs on the middle of the mider 

 surface of the body, especially towards the tip, those on the lower 

 part of the face, and the very long hairs on the tarsi shading 

 into fulvo-ferruginous ; wings brownish hyaline, with a slight violet 

 shade, and marked on all the cells along the hind margin with 

 numerous black dots, as in the allied species ; proboscis black, probably 

 reddish within and at the base when extended. (1988, Larat.) 



Female. Black, thickly clothed with black hairs, and very thickly 

 and finely punctured, except on the middle of the mesothorax, which 

 is smooth and shining, and has a short longitudinal furrow in front; 

 head clothed with bright yellow pubescence, that on the face thinner 

 and paler ; wings with a bright green iridescence, purplish along the 

 veins towards the base ; apical half of the antennae pale beneath ; 

 proboscis mostly reddish ; under surface of body thickly pvinctured, 

 but with some bare spaces along the middle line. (1958, Larat ; 

 2019, Maroe.) 



Closely allied to X. coronata. Smith, from Kaioa ; but in the 

 female of that species (which doubtless has a male similar to that 

 of X. forbesii) the wings have a bright violet instead of a green 

 iridescence.
