6 ME. r. SMITH ON HYMENOPTEEOUS INSECTS 



The cancellation in this species is much finer than in M. spirata, and 

 the whorls are not angulate at the sutures.

It will be observed, on comparing the contents of the present col- 

 lection with others described in previous papers, that the species 

 most widely distributed belong to the families Vespidoe and SpTie- 

 gidce, both containing insects of powerful flight ; whilst among the 

 apterous genera, or those in which the females are onl)'' tempora- 

 rily winged, as in the Formicidcd, the range of distribution is much 

 more circumscribed ; it is, consequently, here that the largest 

 number of new species are foimd. 



In this paper, no less than four new species of the family Thyn- 

 nidcB are described, one belonging to the genus ^hirus, the first, I 

 believe, that has occurred out of Australia. We hope shortly to 

 be enabled to draw up a set of tables showing the range of geo- 

 graphical distribution of the numerous species of Hymenoptera 

 described in the various previous papers on the insects of the 

 Eastern Archipelago.
