P. CAMERON. HYMENOPTERA. 193 



is wide at the apex; it is strongly punctured, the following 3! segments are more finely 

 punctured ; in ail the segments the punctures are clearly separated ; the apical segments are 

 smooth; the i st ventral is closely and strongly punctured; the punctures on the others are 

 weaker and become gradually weaker; ithe 2 nd segment is distinctly roundly narrowed at the 

 base and is as long as it is wide at the apex. Clypeus strongly punctured, narrowed from the 

 eyes, the lower part, (from the eyes) longer than the upper ; the apex broad, truncated. 

 Temples broad, not quite so long as the top of the eyes; rounded behind. The hinder ocelli 

 separated from each other by the same distance as they are from the eyes. Head a little 

 wider than the thorax. Tegulae smooth, the apex weakly punctured. The green, blue or 

 purple metallic coloured Odyneri appear to be characteristic of the papuan Fauna. Five 

 species hâve been described: Pachymenus viridis, Smith, Proc. Linn. Soc, III, 163 ; from Kei 

 and Aru; P. elegans, Smith, /. c, IV, 131, from Batchian and Gilolo ; Nortonia violacea 

 Schult. — Rechb., Verh. z. b. Ges. Wien, 1903, 361 ; N. viridis Schult. Rechb. /. c. 362, from 

 Key and New Guinea, respectively ; and Eudiscoelius métallicus Friese, Zeits. f. Hymen, u. 

 Dipt., 1904, 16. Dr. v. Schulthess — Rechberg appears to hâve overlooked Smith's species, 

 and his viridis, if distinct from Smith's P. viridis, requires renaming. As to the generic 

 position of the species, if they cannot be placed in Nortonia, then Dr. Friese's name Eudis- 

 coelius becomes available. The Malay species of Nortonia are hardly typical with the American. 



Alastor Lep. 



1. Alastor hirtiventris sp. n. 



Heuvel Bivak. November, 750 m. 



Black, densely covered with black to fuscous hair, the underside of the antennal scape, 

 antennal keel and clypeus pale yellow, a broad band on the top ofthe i st abdominal segment, 

 a slightly narrower one on the 2 n d (about one fourth of the length of the segment) ail round 

 on the 2 Dd , the line on the ventral surface broadly narrowed in the middle ; the pubescence 

 on the ventral surface longish, dense and fuscous. Legs rufous, the coxae black, pale yellow 

 below, the trochanters and femora black, the middle femora with a yellowish spot near the 

 apex below, the posterior with a smaller spot; the tibiae and tarsi rufo-testaceous, the fore 

 tibiae at the base narrowly ail round and behind to near the apex and the base ofthe 4 hinder 

 narrowly, black. Wings ruto-hyaline, paler along the apex, the nervures rufous, the basai 2 

 abscissae of the radius almost equal in length, the yà a little shorter ; the i st trans verse 

 cubital nervure straight, oblique, the 2nd roundly curved ; the ist récurrent nervure received 

 near the apex of the basai fourth, the 2"<i shortly beyond the middle. Ç. 



Length 22 mm. 



Clypeus smooth, nearly twice longer than wide, the top rounded, the apex with a 

 shallow rounded incision. Base of thorax transverse, the sides of metanotum broadly rounded, 

 the apex weakly transversely, slightly obliquely striated. The scutellums are flat ; the post- 

 scutellum has a furrow in the centre of the apical half. First abdominal segment cup-shaped, 

 the second a little longer than it is wide at the apex; the latter smooth, not raised. The 

 io th to 12* joints of the antennae are reddish-orange ; the last is black, conical, twice the 

 length of the preceding. 



A large, distinct species.
