EUPELIX CUSPIDATA. 3 



In taking a general bird's-eye view of the Aco- 

 cephalidae, we may make the following remarks for 

 facilitating their identification : — The curious develop- 

 ment of the head of Eupelix renders its naming easy. 

 The banded character of the elytron of the males in 

 Acocephalus proper will call for due attention. The con- 

 trasted and raised nervures on the elytra of Paramesus 

 will afford a clue as to the correct placing of spe- 

 cimens, as also will the almost entire loss of the 

 limbus, point out Graphocrcems, and one or two others. 

 Once more, the long style-like ending to the pygofer of 

 Doratura, and the strong striations on the head and 

 pronotum of Glyptoeephalus, will be regarded as charac- 

 ters of moment and significance.
