turnal in its appearence. But on a forenoon excursion in 
the neighbourhood ot my headquarter Jan. 18th 1905, I 
learned that this was not the case. 
The weather was very bright and hot, and I happened 
to come to an open place with half wet clayey soil, and 
here I had the good luck to meet with a number of the 
Scaptocoris, but under strange circumstances. The insects 
were busy in digging themselves out of the soil, ready to 
spread their wings and instantly fly away. Meanwhile, 
the swarming did not succeed for the majority of the 
specimens, for I secured what I could come over, but, I 
am sorry to say, the numerous Solenopsis (in all sizes) 
took the lion’s share. As soon as the hemipteron came to 
daylight and began to spread its wings to fly away, the 
ants from all sides rushed on the defenceless bug and 
tore off its wings by biting with the strong mandibles 
so that the rather slowly walking Scapfocoris could not es- 
cape from the furious ants and soon was devoured by them. 
I may add that I did not ever since witness anything 
like regarding the Solenopsis and the Scaptocoris. 
The Scaptocoris terginus spreads a strong odour, not 
unlike that of some Pentatomids, as for an instance Doly- 
coris. When a number of the Scaptocoris were put in the 
cyanide bottle, they produced a humming sound, in some 
way resembling the stridulation of our small grasshoppers, 
though not so sharply defined. 
4. A little known Hemipteron (Fig. 2). 
In his „Nova Hemiptera Faunarum Argentinae et Uru- 
guayensis“ Dr. C. Berg founds a new genus (Lobepomis) 
with a single new species (peltifera) on a very singular 
hemipteron, which he enumerates under the subfamily 
Halydina. Dr. Berg only records the occurrence of two 
specimens of this species, the one from the Province of 
Mendoza in Western Argentine, the other from Uruguay. 
It seems as the Lobepomis peltifera Berg has not been
