 Ashmead seems to have had before him this species or one 

 closely allied when he drew up his description of Hop- 

 linus inultispiuus. Barber identifies multispinus with my 

 perclavatiis, but the latter is a larger insect with none of the 

 characters distinguishing Hoplinus and disagreeing funda- 

 mentally with Ashmead's description.
