Family Aegeriidae (= Sesm/ac). Tliis faiiiily shows a cortain 

 relationshii) witli thv S/>/ih/<//</a('. 



In Beütenmüllek's enormous work (1900) Dyar lias described 

 the oaterpiUars. Fracker (1915) ad()j)ts these results with some 

 modifications. Dyar says (p. 228) that all the tuberoles are single, 

 there never being auy development of warts or secondary hairs. 

 The abdomen has type I with .s. poststigmalis and s. infrasf/)/- 

 malis united. 



It is the same on the prothorax^ hut there is a s. subdorsalis 

 inf.^ and rerruca siqjrastif/maHs and /'. prostufnialis each bear 

 three setae, the two s. hasales are on one tuberculum. 



Mesothorax and Metathorax according to Dyar : "Ia and Il> uni- 

 ted, Ila and Ilb likewise, but IV and V well separated, IV being 

 even nearer to III than to V, a curious circumstance". 



I think there are : s. dorsalis -\- s. dorsolateralis^ s. suprastiy- 



inaïis -j- s. prostigmalis^ s. poststigmalis^ s. inffastig?nalis, s. basalis, 



s. pedalis. 



Rhopalocera. 



Fracker believes that the butterflies arose from the Microlepi- 

 doptera in a time when y. and vi had not yet become adjacent. 



Family Hesperidae. No material in the coll. Kall. 



Fracker (1915, p. 127) folio ws the descriptions of Scudder 

 (1889) not only in this family but in all the 'Rhopalocera. 



This family deviates a great deal from the ethers which Hand- 

 LiRSCH takes together under the name of Papilionidae s. 1. 



Fracker says : "Secondary setae numerous, small fiattened plates 

 sometimes present, possibly showing position of primary setae, 

 setae on the head often plumose." 



Family MegatJiyiiiidae with the last-mentioned one united to 

 the Hesperioidae. 



Fracker (1915, p. 128) says, "no setae on dorsal half, nume- 

 rous on ventral half of the first two thoracic segments, rare or 

 absent on abdomen except prolegs." 



Family Lgraenidae. These larvae resemble ZYGAENOIDEA a 

 little (Fracker 1915, p. 128).
