with a pair of 7. stagmadice, Stdgr., for comparison. He said: 
“The first-named specimens were presented to the Hope 
Collection by Mr. C. M. Dammers, having been captured by 
him in Tucuman, N.W. Argentina, in March 1912. They 
show points of resemblance to 7’. stigmadice, Stdgr., and T. 
xanthodice, Luc., but are clearly distinct from either. I at 
first thought that they represented a new species, but on 
further examination it appeared that they might be referred 
to a form described by Rober in Seitz’s ‘ Macrolepidoptera of 
the World’ as T.-immaculata, though in one small respect the 
male does not exactly tally with Rober’s description. He 
says that the dusky stripe in the cell on the under-side of the 
hind-wing is indistinctly forked at the distal end. In the 
present male specimen it is not forked at all. 
“The genus Tatochila to which these species belong, is 
entirely confined to South America. It is undoubtedly a 
natural assemblage, though its generic rank may possibly be 
open to question. Its nearest affinities appear to be with 
the Metaporias of Central Asia, and it has also points of 
contact with Synchloe. The scent-scales of those members of 
the genus which possess them are unusually large and quite 
distinctive. It is interesting to note that I find no scent- 
scales in J. tmmaculata, nor T. demodice, Blanch., though 
T. stigmadice, which seems to be much nearer to zmmaculata 
than demodice is, possesses them in good numbers. 
“ The present, though not a new species, appears not to be 
well known. We may confidently hope that Mr. Dammers 
will do much to increase our knowledge of the fauna of the 
interesting district of the Neotropical Region to which he is 
devoting his attention.” 
ANTS AND THEIR GuEsTs.—Mr. DonisTHorPE exhibited a fine 
series of Claviger longicornis, Mull (including live specimens), 
with its proper host Lasius umbratus mixtus, with which he 
had taken it at Box Hill on May 16 and 23. He also exhibited 
the common Claviger testaceus (to show how very distinct 
C. longicornis is) with its principal host L. flavus ; and specimens 
of the Acari Trachyuropoda bostocki, Sphaerolaelaps holothoroides 
and Antennophorus uhlmani taken at the same time. 
He gave an account of the history of C. longicorms both
