206 THE STUDY OF INSECTS, 



beyond the discal cell, and which do not have what 

 appears to be a cross vein between veins II and III of 

 the hind wings.

The Zygaenids, p. 326 Family ZvG^NiDiE. 



GG. The Window -winged Moths. — Moths in which vein 

 III of the fore wings is five-bi-anched aiid in which all of 

 these branches arise from the discal cell (Fig. 404), p. 



328 Family Thyridid^e. 



GGG. The Hawk-moths. — Moths in which there appears 

 to be a cross vein between veins II and III of the hind 



wings (Fig. 407), p. 329 Family SPHINGID.E. 



DD. The Frejiulinn-losers. —Specialized Macrofrenatae, in which 

 the frenulum has been supplanted by a greatly extended 

 humeral area of the hind wings. In some of the more gen- 

 eralized forms a rudimentary frenulum persists (Bombycidae 

 and Lacosomidse). This division includes three groups of 

 families: the Frenulum-losing Moths, the Skippers, and the 

 Butterflies. The grouping together of the families included 

 in this division is merely provisional, as it is probable that 

 the loss of the frenulum has arisen independently in several 

 of them. 



E. The Frenulum-losing Moths. — In these moths the antennae 

 are usually pectinate ; they are never enlarged into a club 

 at the tip. 



F. Moths with cubitus of the fore wings apparently three- 

 branched. 



G. Moths in which veins III3 and III4 coalesce to a great 

 extent. The Saturnians. p. 339. 



Superfamily Saturniina. 



GG. Moths in which veins III3 and III4 do not coalesce 



beyond the discal cell. p. 357. .Family LACOSOMiDiE, 



FF. Moths in which cubitus of the fore wings is apparently 



four-branched, p. 359 Family LASlOCAMPiDiE. 



EE. The Skippers. — These are day-flying Lepidoptera which 

 resemble butterflies in usually holding their wings erect
