THE SPHEGOIDEA AND VESPOIDEA 



BY TREVOR KINCAID 



THE collection upon which this report is based is a small one, 

 including but nine species, but it is of considerable interest from 

 the fact that but a single representative of the above groups has 

 been recorded from Alaska, namely Dolichocrabro -wickhami 

 Ashmead, 1 which was collected by Mr. H. F. Wickham at 

 Fort Wrangell. At the same time and place Mr. Wickham cap- 

 tured a Pemphredonid which Mr. Ashmead determined as Pas- 

 salcecus cuspidatus Smith. In the collection of the U. S. National 

 Museum there is also a Chrysid collected at Fort Yukon by Mr. 

 L. M. Turner in 1877. This has been determined by Mr. 

 Ashmead to be Omalus sinuosus Say. These three species, to- 

 gether with those listed below, bring the total number of known 

 Alaska forms up to twelve. It is evident that the coastal regions 

 of Alaska do not afford a favorable environment for either 

 fossorial Hymenoptera or wasps.
