Hoplocampa flavicornis (Provancher). 

 Selandria flavicornis Provancher, Natural. Can. vol. 10, 1878, p. 100. 



Type. Public Museum Quebec, bearing yellow label 60 and 

 name label "Selandria halcion Harris" on the other side of which 

 is written "Selandria flavicornis Prov." 



Provancher considered this the male of halycon but from notes 

 on the type I am more inclined to believe that it may be the male 

 of xantha Rohwer. It is, however, impossible to be sure because 

 of the difference in the sexes and it is advisable to consider the 

 two as separate until more evidence is available. The following 

 .notes on Provancher's type may be useful. 



Stigma broader near base tapering to an acute apex; interradius leaving 

 stigma near apex and joining the third cubital about the length of the third 

 intercubitus from the apex; third cubital cell longer on the radius than the 

 first and second; hypopygidium rather broadly truncate with angles 

 rounded; clypens arcuately emarginate, lobes broadly rounded; middle 

 fovea rather large walls sloping rectangular in outline; ocellar basin poorly
