By \V. F. KJRBY, J'.L.S., F.E.S., Assistant in the Zoological DeparlmciU, 

 British Museum (Natural History). 



The collection submitted to nic consisted of a numbei- of specimens pt-eserved 

 in spirits and contained in small phials, a large propoi'tion of the specimens being 

 Foniiicidic (ants). It should, however, be pointed out that, although spirit is a 

 convenient method for collecting specimens, it is undesiiable to employ it for any 

 insects except hard-shelled beetles or bugs ; for the exposed wings of insects aie 

 very liable to get torn in it, and the hair of bees, etc., gets matted together and 

 spoiled. 



With the exception of a few specimens, which were too much damaged for 

 identification, a full list of the species obtained is given below. Altogether 

 twenty-eiglit species of Hyineiioptera acukata are here enumerated, of which six 

 appear to be new to science.
