In thisgroup the branches of the radial vein enclose or tend toenclose an irregular space just behind the costa, at about themiddle or nearer to the apex. 2. StapliyUnid type (fig. 20).—The chief characters of4 this group are found in the absence of transverse veins; there are,therefore, no enclosed spaces on the wing. The veins, more-over, are much more simple, and the first or exterior medianvein does not extend right across the disc and is not joined CLASSIFICATION. 41.
