Heteroptera. 
Walsh (Proc. Bost. Soc. Nat. Hist. ix. p. 313) refers to articles published 
in agricultural journals in which the following species of Heteroptera are no- 
ticed : — Phytocuris linearis (Beauv.) = Capsus ohlineatus (Say), Micn'opus leii- 
copterus (Say), and Reduvius raptatorius (Say). 
Bold (Nat. Hist. Trans. North. & Durh. i. p. 134) records the capture of 
several rare and local species of Heteroptera. 
SCUTATA. 
This group is divided into the following families by Stal (Hemiptera 
Africana, i.) : — Arthropterida (Fieb.), Cydnidu, and Pentatomida (StSl) inch 
Scutellerida, AsopidU) Pentatomida, Phyllocephalida, Acanthosomida, and Tes- 
saratomida. The Arthfopterida=iPlataspid<^ (ldd\\..')'==.Thyreocoridce (Am. & 
Serv.), and the Cydnida—Cydnidce (J)o\i.)—Spiniphdes (Am. & Serv.), ex- 
cept that, according to Stal, the genera Chlcenocm'is (Bunn.) and Stromhosoma 
(A. & S.) have to be transferred from the former to the latter *. Stal does 
not give his reasons for this opinion, which seems to the Becorder not to be 
well founded ; but, however this may be, the two groups just mentioned are 
undoubtedly well marked. This, however, is by no means the case with the 
third family, which consists of such heterogeneous materials that literally 
the only positive character distinguishing it from the Cydnida is the partial ex- 
posure of the first abdominal segment. The author’s subfamilies constitute 
groups more nearly equivalent to his Arthropterida and Cydnida, except that 
his Acanthosomida must be combined with the Pentatomida, the possession 
of two-jointed tarsi being a character quite insufficient for tlie separation of 
Acanthosoma, for example, from such forms as and its allies. Of 
the remaining subfamilies the Asopida, Tcssaratomida, and Phyllocephalida 
call for no remarks, and the Scidellerida are identical with the Pachycoridre 
(Dali.) -b except that the curious and rather puzzling genus 
Cyptocoris is transferred to the Pentatomida. To the last-mentioned group 
* It would appear also that the Odontoscelides are referred by StSl to the 
Cydnida (see p. 31),
