AMERICAN HKMIPTERA. 6 



Fiuiiily PENTATOMID^. 



A brief synopsis ot" our four tnain subfamilies may be found in 

 Comstook's Manual for tiie Study of Insects, page 128, where, 

 however, they are given family rank. In using this, allowance 

 must be made for certain aberrant forms in the sul)family Asopidse, 

 etc., in which the scutelluni covers almost the entire abdomen, as it 

 does in the Corimelienidie and Scutellerid:e, For other synopses 

 see: Stal, Hemiptera Africana, i, p. 82; and Genera Pentatomi- 

 darum Europ^e disposuit, in Of. Kong. Vet.-Akad. Forh., xxix, no. 

 H, p. 81, 1872 (from both of which the Cydnidte, including the 

 CorimekTenidse, are excluded) ; Fiebei", Die Europaischen Hemip- 

 tera, p. 26 (giving family rank to the Cydnidie and Tetyrse) ; and 

 Aniyot and Serville, Hemipteres, p. xv et seq. 



Subfamily Corimel^enid.e. 

 This family is united with the Ch/diiidte by P^ieber and Stal, and 

 is placed in a group, Odoiitoscelides, with genus Odontoscelis by 

 Amyot and Serville (p. xix). Dr. Uhler separates it as a distinct 

 family under the name used here, and in the Lethierry and Severin 

 Catalogue it is placed as a subfamily under the same name. There 

 is but one genus in our fauna. 



Gemis <'0RIWKL,.E:V4 White. 



The following synopsis is founded on the more obvious characters 

 as I have been al)le to make them out. Unfortunately, many of 

 them are comparative, but with the more common species in hand, 

 such as uiiic.olor, niUduloldes, lateralis and pulicaria, which will be 

 found in almost every collection, the species should be located with 

 reasonable certai nty. 



C. deiiudata Uhler and marginalia Dallas are omitted, as I have 

 not seen specimens and cannot locate them by the published 

 descriptions.
