278 Mr. T. D. A. Cockerell — Descriptionfi and 



s.m. very near the end ; third s.m. broad above, not greatly 

 elon"-ated ; hair of femora dull white, of tibise and tarsi 

 fuscous, red on inner side of anterior tibise ; tibial scopa 

 dark fuscous ; hind spur with few long slender teeth (long- 

 pectinate). Abdomen shining, without hair- bands, the 

 dense hair at apex black ; dorsal surface of abdomen with 

 small but very distinct punctures, especially dense on basal 

 two-thirds of second segment. 



^ . — Length 9 mm. 



Much smaller and less robust than the female, but struc- 

 turally similar ; face with thin white hair, not at all con- 

 cealing surface of clypeus; ilagellum entirely black ; vertex 

 black-haired, but the dark hair of thorax above much less 

 conspicuous than in the female; apical half of hind tibiae 

 dark chestnut-red ; hind tarsi pale ferruginous. Flagellum 

 moniliform. 



Hab. Female ( = type) from Stradbroke Island, Queensland, 

 Oct. 2, 1911 {Hacker ; Queensl. Mus. 13). Male from Bris- 

 bane, April 1, 1912 {Hacker; Queensl. Mus. 58). 



Rehited to P. punctatus (Sm.) and P. obscurus (Sm.). 

 From P. punctatus (?) it is known by the larger size and 

 largely black or dark fuscous hair of head and thorax. 

 From P. obscurus it differs by the smooth sparsely punctured 

 clypeus and the colour of the tibial scopa. The male is very 

 like that of P. thornhiyhensis, Ckll., differing by the larger 

 size, the thin white hair of face, the black flagellum, the 

 ferruginous tibial spurs, and the white hair of abdominal 

 dorsum extending only to middle of second segment, beyond 

 which it is short, sparse, and black. 



Paracolletes thornleighensis, Cockerell. 



Two males {Froggatt, 159) from Thornleigh, N.S.W., 

 1890-91, show that this species has a distinctly bluish 

 abdomen. The colour is so faint in one of them that I 

 placed it, as I did the type, among the species without 

 metallic tints. The legs are dark reddish to black. Among 

 Smith'*s species P. thornleighensis is nearest to P. providus, 

 from which it is known ( c? ) by the dark hair of thorax 

 above. The brilliantly shining area of metathorax separates 

 it at once from P. providellus, Ckll. 



The specimen which carries the nutnber 159 also carries a 

 number 30 ; the original types were marked by the same 

 collector 32, so I infer that he regarded the specimens with 

 evidently bluish abdomens as distinct. It is perliaps possible 

 that there are two species, but with the evidence before me 

 I cannot well separate them.
