FOSSORIAL WASPS. 625 



Easily distinguished from pimctifrons by the golden pubescence 

 of the head and abdomen, by the almost obsolete puncturation of 

 the mesonotum, and by the coarse longitudinal striation of the 

 median segment, the striation in punctifrons being oblique.

I think all these are identical — certainly the first four, and 

 almost certainly Cameron's species also.

I suspect that this will prove to be a synonym of punctifrons, 

 but the description is too poor for certainty. 



Hah. Laguna, Philippines (Stangl).

 I cannot identify this species.

Closely allied to insularis Sm. and priscum Turn. The punc- 

 turation of the second ventral segment is microscopic. 



Rab. Ceram (Wallace).
