OBSERVATIONS ON LACORDAIRE. 147 



Winged or apterous), there are not less than eighteen tribes — 

 ScythropideSj Promecopides, Gonipterides, HyperideSy Ithy- 

 cerides, DiuhathrariideSy Aterpides, Cleonides, Hylohiides, 

 Erirltinides, AmalactideSj Ajnbatides, PetalochilideSy Oxy- 

 coryn'ides, Belides, Eurhynchides, Cylides, and Ajnonides. 

 Proceeding to the second Phalanx, we have again two 

 Sections : Section A (Intermediate segments of the abdomen 

 not angulated at their extremities) contains thirteen tribes — 

 CybebideSf Attelabides, RhinomacerideSj Ecte7nnor'hinides, 

 MesoptilideSj ScvlopterideSf Erodiscides, Otidocephalides, 

 3fa(/daUdes, Ealanides, Anthonomides, Ceratopides, Tri- 

 gonocolides. With Section B (Intermediate segments of 

 the abdomen angulated at their extremities) we find four 

 tribes — Co7^yssome7-ideSf PrionomerideSj TycJiiides, and 

 Cionides. With the latter this volume terminates. 



Many of these tribes are also divided into ^'' groiipes" — the 

 Br achy derides, for instance, into twelve, the Otiorhynchides 

 into seventeen, and so on. Some of these groups might 

 probably with advantage be ranked as tribes — i. e. sub- 

 families. 



From M. Lacordaire's tabular statements of the characters 

 of the tribes and groups scattered through a thick volume of 

 637 pages, we have made the following analysis of his 

 arrangement as far as it is applicable to the genera of tlie 

 family which have members indigenous to this country. In 

 this case we have modified the terminations of the names of 

 the sub-families so as to bring them into unison with those 

 adopted by many of our leading Zoologists.

 without a peduncle.
