DESCEIPTION OF A NEW GENUS, AND SOME NEW SPECIES OF 



CORYLOPHIDM. 



BY EEV. A. MATTHEWS, M.A. 



Among the New Zealand Corylophidce in the collection of Dr. 

 Sharp, I found the two very remarkable species described below. In 

 superficial appearance these insects much resemble the Triclioptery- 

 gidcd, but really belong to the Sericode7nna of the Corylopliidcd . From 

 Sericoderus itself they are distinguished by their peculiarly formed 

 11-jointed antennae, and other anatomical differences, and thus con- 

 stitute a very distinct genus, which I propose to call Anisomeristes, 

 from the unequal proportions of the articulations of the antennae, and 

 of which the following are the chief diagnostic characters : —
