points ; andtlie stuiupof the cubital nervure, found well developed 

 in OpJiioii, is absent. In some cases the smootli space is present 

 without having horny points in ir, or they are very faint. In eitlnM- 

 case I believe it \\ill be found that the base oi" the cubital nervui'e 

 is thickened, which is not the ca^^e with Ophlon, sc7ish str. In 

 view oF the great similarity of the species of Ophion, it seems to 

 me desirable to adopt Euicospilus as a distinct genus. Species 

 belonging to it are found in all parts ot" the world." Later, how- 

 ever {op. cit. 1899, p. 10-i), he sinks it as a mere subgenus of 

 OpJiion, from which he regards it as differing in the thickened 

 basal radial abscissa and the corneous plates of the glabrous alar 

 area, or it would be more correct to say, in the mere possession of 

 such a glabrous area, with or without corneous spots.
