SYNOPSIS

Eight new species of the Limoniine genus Antocha Osten Sacken are
described,all from Kumaon and Assam, India.

The preceding part in this series of papers was published in ry7o (Proc. R. ent.
Soc.Lond. (B) fg : 73-8). At this time I am discussingstill further speciesin the genus
AntochaOstenSacken,previouslyconsideredin the precedingthreepartsof this series.
All of the noveltieswere collectedby Dr FernandSchmid in variousparts of Assamand
Kumaon, India. I am greatlyindebtedto Dr Schmid for the privilegeof retainingthe
typesof the new species.

The figure of the male hypopygium provided at the time of original publication, islackingin certaindetails,and a new drawingis shown (fig. t). The simple apexof theouter dististyle,d, shouldbe noted.
