 hook shorter than half the length of eighth abdominal segment, or with

 always present on meso- and metathorax. Tarsal setae weak, one or two in 

 Zonitis, two in I.eptopalpus ; seta on trochanter either long, in Zonitis, or 

 normally developed, in Leptopalpus. Spiracle-bearing hook short and dis- 

 tant in Leptopalpus and in the North American species Zonitis bilincatus ; 



normal in other species of Zonitis NEMOGNATHINI-ZONITIDES. 



Genera Zonitis, Leptopalpus, and possibly Sitarobrachys. 



First instar without caudal setae. Epicranial and frontal sutures distinct,
