The genus Si/sfelloderes is new to Australia, but is probably of 

 the same world-wide distribution as I/euicocephaltis. It is repre- 

 sented in the Neotropical region by a few (partly undescribed) 

 species, in North America by one, and in Europe by one species. 

 Xo species has hitherto l>een lecorded from Africa or Asia, but I 

 know an undescribed species fiom the Philippine Islands, and the 

 insect described by Enderlein fiom Crozet Island under the name 

 Fhthirocoris antnrcticits is dou1)tless the larva of a Si/sfelhderes.
