Exoleta. 



Harpe a curious form, bifurcate, without corona, inner 

 point small and peaked, outer of much thicker chitine 

 is larger and also peaked, but bent at right angles ; clasper 

 a curved arm ; uncus parallel to the tip which is broad and 

 flattened ; vesica has a bulbed cornutus also a slender 

 cornutus ; juxta peaked in the centre. 



Solidaginis. 



Harpe broad and rounded, without corona, or spines ; 

 cucullus which hardly leaves the costa, small, peaked at the 

 anal angle ; armature of harpe absent ; uncus tapered ; 

 vesica without teeth. 



The Xylinas bear as a rule a strong family like- 

 ness, zinckenii probably forming a connecting link to the 

 Cncullias. The following genera require a good deal of 

 re-arranging, and I believe the genitalia will prove an 

 important help in the sequence. There is a certain 

 amount of connection between the groups, which in the 

 present classification, has unfortunately been interrupted, 

 by interspersing several little odd genera among natural 

 relatives. The Cucullias, with their narrow coronated 

 harpes and simple clasper, lead to the Heliothida, from 

 which should be excluded Anarta and Heliaca. The harpe 

 of the Heliothias, being very closely allied to the Cucullias, 

 except that the clasper is lost. Asteroscopus, including 

 Valeria oleagina and Miselia bimacvlosa again form another 

 connecting link, and continue the sequence to the Plusidce, 

 which may be followed by Habrostola and made to include, 

 or at any rate be followed by the Amphipyrid<z. 



Xylina rhizolitha ; ornithopus. 



Harpe with small cucullus divided, with a few spines of 

 corona ; clasper long and curved ; ampulla extends below 

 the cucullus in a long curved arm ; clarus produced and 

 roughly rounded ; uncus tapered ; vesica with small bunch 

 of teeth.
