Chrr/sochlon's Com'cc and C. chn/sUhis, recently describetl 

 by Thomas, appear to be closely allied to C. hotteutota and 

 C. obtu.sirosfris respectively, and no marked cranial characters 

 are stated by which they can be readily distin<j;ui.shed. I am 

 not acquainted with either of these recently described species.

XXXllI. — Xew Species of Sphegidaj from Australia. 

 By R. E. Turner. 



Only two genera allied to Ampulex have hitherto been 

 recorded as Au.'stralian, each containing a single Australian 

 ."pecies. Ajthelotoma was described by West wood for a 

 I'asmanian species, and I am now able to describe two 

 additional species from the mainland. Dolichurus carbonariusy 

 Sra., belongiiig to a small Ijut wide-ranging genus, was 

 described by Smith from Champion Bay, W.A. I can now 

 record its occurrence at Mackay, on the Queensland coast. 1 

 also de.scribe three species of a new genus, which is, perhaps, 

 nearest to Aj^helotoma. 



Genus Aphelotoma, Westw. 



Aphfh'toma, AVestw. Proc. Ent. Soc. London, 1840, p. 12. 

 1'ype, Aiihehtoma tasmanicay Westw.

(^ . Head and thorax opaque, delicately reticulate. Clypeus 

 broadly rounded anteriorly, without a median carina. Head 

 broad, the eye.s not quite touching the base of the mandibles 

 and convergent towards the vertex. Pronotum narrow, 

 elongate, depressed anteriorly, broadest posteriorly, with a 

 median longitudinal sulca. Mesonotum short and broad.
