Genus 3. NOLASENA. 



Statura parva. Corpus vix robustum. Proboscis mediocris. 

 Palpi validi, porrecti, compressi, caput longe superantes; articulus 

 2us latus ; 3us lanceolatus, 2i dimidio non longior. Antennae gra- 

 ciles, simplices, corporis dimidio longiores. Thorax laevis, squa- 

 mosus. Abdomen alas posticas vix superans. Pedes graciles, non 

 pilosi, calcaribus longissimis. Alas anticae mediocriter lata?, apud 

 costam subrectae, apicesubrotundatae, margine exteriore vix obliquo. 



Size small. Body hardly stout. Proboscis moderately long. 

 Palpi stout, porrect, compressed, extending far beyond the head ; 

 second joint broad ; third lanceolate, not more than half the length 

 of the second. Antennae slender, simple, more than half the length 

 of the body. Thorax smooth, with squamose hairs. Abdomen 

 hardly extending beyond the hind wings. Legs slender, not pilose ; 

 spurs very long. Wings moderately broad. Fore wings almost 

 straight in front, somewhat rounded at the tips, hardly oblique 

 along the exterior border. This genus, in the structure of its palpi, 

 much resembles Hyblcea and also the Hypocalidce, which family are 

 closely allied to the Hyblmdce.
