Nomia lyonsia, sp. n. 



$ . — Length nearly 11 mm. 



Black ; the first four abdominal segments with moderately 

 broad emerald-green bands suffused with vermilion ; scu- 

 tellum depressed in middle, but not bituberculate ; post- 

 seutellum with a pair of large lamellae or teeth ; clypeus with 

 a fine keel. Wings dusky hyaline. 



So exactly like the Indian N. elHoti, Smith, that it is 

 difficult to point out many differences. The postscutellar 

 teeth are larger than in ellioti, and the punctures of the 

 mesothorax are smaller and evidently of two sizes. The 

 abdomen is more strongly and closely punctured, especially 

 on the second segment. The antennae are dark, with the 

 flagellum faintly reddish beneath toward the apex.

It seems not altogether impossible that this is the female 

 of N. darivinorum, Ckll., described from Port Darwin. The 

 localities, however, are about 1800 miles apart, and probably 

 the species are distinct. N. lyonsia agrees structurally with 

 N. rubroviridis, Ckll., but differs by the black hair covering 

 apex of abdomen, partly black hair on thorax above, rather 

 large punctures of mesothorax, and only moderately broac^ 

 abdominal bands. 



Gastropsis pubescens (Smith) . 



Brisbane, Queensland, Nov. 27, 1911 {H. Hacker). 

 Queensland Museum, 54. 



Dioxys aurifuscus (Titus). 



Dioocys fulvohirta, Ducke, from Durango, Colorado, is 

 apparently a synonym. Titus described, his species in a 

 distinct genus {Chrysopheon), and it was overlooked by 

 Ducke. 



Xylocopa varians, var. piurensis, v. nov. 



? . — Like var. incarum, Ckll., but hair on outer side of 

 middle and hind basitarsi and. end of hind tibiae shining 

 cream-colour; herein it resembles var. ecuadorica, Ckll., but 

 it differs from that in having the hair on inner side of tarsi 

 (especially hind tarsi) bright ferruginous.
