This is possibly the same as H. insularis, Grote, and 

 synonyms ; it is very similar, but greyer in tone. If iden- 

 ical Vittipalpis would have priority. 



Talae, Berg. (Hyboma), An. Soc. Arg., v, p. 184 (1878), 

 probably belongs to this genus; the species is un- 

 known to me. Harma, the oldest name for the genus 

 is preoccupied.
