are referred, besides the groups of which Sciocoris, llalys, and Pentatoma may 
be regarded as the types, the remainder of the Eurygastrida; (Dali.), Podops 
and its allies, and Aspongnpiis and Dinidor (= Cyclojjeltd) ; the last two are 
certainly not in their proper position. This group also includes a portion of 
the Megarhynchi, referred to various genera, whilst others are placed among 
the Phyllocephalida. The total number of species described is 340, of which 
51 are new. Seventeen new genera are also characterized, and the references 
to the previously described genera and species include many valuable notes 
on synonymy. Under some of tlie subfamilies the author has tabulated ge- 
nera not represented in Africa j these seem all to belong to the eastern hemi- 
sphere, but do not include the whole of the old-world genera. 
Mulsant & REYfPunaises de France) divide their tribe oi Scutellerides into 
five families: — 1. Coptosomiem 2. Eucoriens (==.OdontosceUdes) 3. Psa^ 
castiens ; 4. Trigonosomiens ; 6. Graphosomiens : each of which is again sub- 
divided into branches ” and ^^rameaux.” It is almost unnecessary to say 
that all these subdivisions are not only useless but positively inconvenient ; 
with so small a number of species, they neither facilitate determination nor 
assist in giving a' clear idea of the relations of the forms under consideration. 
Douglas &ScQTT divide theBrirish species of this gToup into nine families, 
namely Cydnidee, OdontoscelidcB, Scicorid( 2 , Eurygastridm^ jEliidcB^ Podopidcc^ 
Pentatomidee, Asopidco, and Rapliigastridce (British Hemiptera, vol. i.).
