120 Prey of Species of Scopeuma Mg. ( Scatophaga Mg.). 
Sphecodes reticulatus Th. is associated with Halictus prasinus Sm. 
Sphecodes monilicornis Kirb. ‘ Halictus rubicundus Chr. is its chief 
host . 1 
Sphecodes divisus Kirb. Delete Andrena as a host. 
Sphecodes ferruginatus Schr. ‘ certainly not parasitic on Halictus 
rubicundus Chr. but on species of the calceatus group.’ 
Halictus fulvicornis Kirb. ‘ Smith’s subfasciatus were a mixture 
of freygessneri and rufitarsis.’ 
Halictus nitidiusculus Kirb. and minutus Kirb. ‘ Very critical. 
Smith’s minutus were practically all nitidiusculus .’ 
Halictus tetrazonius Kl. ‘ If correct, Yorks, is an unexpected 
locality.’ 
Halictus rufitarsis Ztt. ‘ Smith took this year’s before he described 
atricornis as new and when he did describe atricornis he mixed nitidiusculus 
in the type set of specimens.’ 
Andrena tibialis Kirb. (Wooley, Smith). ‘ Improbable, his specimens 
are wrong.’ 
Andrena spinigera Kirb. is a southern English bee. 
Andrena ovatula Kirb. and Nomada lineola Pz . ‘ not worth considering 
without other records.’ 
Nomada flavopicta Kirb. The host is Cilissa leporina Pz. not yet on 
record for Yorks. 
Nomada xanthosticta Kirb. Smith’s xanthosticta was obtusifrons. 
The true xanthosticta he described as bridgmanniana, his lateralis was 
bucephalae . 
Epeolus cruciger Pz. ‘ Certainly as a rule cruciger is on succincta 
and notatus on the other species ’ (of Colletes). 
Anthophora retusa L. (Wooley, Smith, Pannal, Roebuck). ‘ Seems 
unlikely, especially as it always forms great colonies, being gregarious.’ 
Anthophora quadrimaculata Pz. (Leeds, 1816) ‘ ???’ 
Megachile centuncularis L. ' Should contain probably M. versicolor 
which occurs in N. England and is the common Irish species.’ 
Coelioxys trigonus Schr. ‘ No doubt entirely wrong.’ The genus 
Coelioxys are all critical species. Smith’s mandibularis are acuminata Nyl. 
Yorkshire hymenopterists are greatly indebted to Dr. Perkins for 
the above critical notes.
