abdomen shining, with sparse exceedingly minute punctures; 

 apex with dark purplish-fuscous hair, but glittering pale hairs at 

 sides of apical half. 



In my Table, in Annals and Magazine of Natural History, 

 September, 1904, this runs to no species, because the first r.n. 

 meets second t.c, and the red of abdomen is bright. The dark 

 legs separate it at once from P. lacthius and P. lithusca; in the 

 black apex of abdomen it resembles the Tasmanian P. tuchilas 

 and P. tilachus; but P. tuchilas has the hind margins of the first 

 two abdominal segments darkened, and the sculpture is different, 

 while P. tilachus has a much darker abdomen. The insect is 

 also quite distinct from the various Australian species, I have 

 described in recent years. 



{3.)Halictiisla7iaritis 8m[th. One male. Devenport(138, 10714). 

 Halictits lanuginosus Smith, is apparently the same. 



(4:.)Paracolletes carinatus{Smith). One male "Tasmania "(135^ 

 10709). The abdomen is a fine dark blue, instead of green, and 

 the second segment is more closely punctured; but the insect 

 agrees so closely with female P. carinatits, that it is safe to regard 

 it as its male. 



{b.)Paracolletes melhournensis Cockerell. One female. Mt. 

 Wellington(14 1,6458). 



(6.)Paracolletes leai, n.sp. Ulverstone(139, 10712). 



9. Length about 12 mm.; slender, black, the abdomen obscurely 

 metallic, the fifth segment entirely greenish, the hind margins of 

 the others suffused with reddish-purple; scanty hair of face, sides 

 of thorax, and metathorax, glittering whitish, but dorsally and 

 especially about tubercles fulvous, on vertex fuscous (perhaps 

 some fuscous on mesothorax, but it is apparently denuded); liead, 

 thorax and abdomen shining; clypeus shining, with large punc- 

 tures, and a median ridge, failing on the lowest fourth; mandibles 

 with a red subapical ring, and slightly reddish at apex; a sharp 

 keel between antennae; flagellum reddish beneath at apex; front 

 with very distinct rather dense punctures, except at sides, where
