elongate (to a remarkable extent), and the lateral lobes 
diminished. The Telephoridae (Rhag. limbata) exhibit a 
remarkable specialisation in the very bulbous form of the 
median lobe, but the New Guinea Chauliognathus? (fig.139) 
is much less remarkable, and departs to a comparatively 
slight extent from Lampyris. Malthinus and Malthodes 
appear to be modifications of the Telephorid plan.

AFFINITIES OF SOME OF THE 
MALACODERMID FAMILIES 
As regards “ Melyridae ” we fail to connect them satis- 
factorily with the Malacoderms, but as we cannot assign 
them any other place in a system we treat them here. In 
addition to this we may remark that the family will very 
likely have to be sundered in two or more. Malachius, 
however, may prove to be a form annectant to the highly 
specialised Astylus (Melyridae proper) and the aberrant 
Balanophorus. As regards the sac, the lower forms of the 
Malacoderms have it but little specialised, but in higher 
forms (those allied to Yelephorus and the higher kinds of 
Lycidae) this structure becomes complex, as it is in all 
the Melyridae we have examined. Phlocophilus cannot be 
admitted to either the Malacoderms or the Melyrids till 
annectant forms are brought to light.

Under this name we can associate at present only a 
few families, because we are of the opinion that several
