Thus It is by no means a vulgar name as suggested by Van 

 Duzcc.' To conform with modem usage the termination must be 

 changed to -idae, but this cannot affect the nomenclatorial stand- 

 ing of the term. Similarly subfamily and tribal names must now 

 end in -inar and -ini respectively, but no one thinks of ignoring 

 the subfamilies and tribes of St&l and Renter because these au- 

 thors used the terminations -ina and -€nria in naming those 

 groups.' Renter. Bergroth, and others* have adopted the 

 name Miridae, and we may well follow them since their view 

 seems to he supported by the evufrnrr. frnm whii-fuvrr <ttand- 

 point it may be viewed. 



As a basis for this review of the external characters of the 

 Miridae, I have used a common and widely distributed species, 

 introducing such comparative material as T have found avail- 

 able. Most of the technical terms will be fotmd equally ap- 

 plicable in the other families of Heteroptera. Earlier treat- 

 ments of the subject may be found in the writings of the au- 

 thors cited, especially in the works of Renter.'* which are 

 fundamental for the study of this family. 



The Head. (Plate vii, fig. i.) 

 The term tylus (dypeus) may well be applied, as in other 

 families of Hrteroptcra. to the anterior median portion of the 

 head." The triangular pieces on each side of the tylus may 

 for the same reason lie called the juga (Xho Joe hst He ke of 

 Rcutcr). The lorae {KopfsUgcl. maxillary laminae**) lie just 

 inferior to the juga. from which they are set off by an im- 

 pressed line. Bcktv ' Htsteriorly th^ may be fused with 

 the gcnac ( hrar < . as in fig. i ; or they may be 



marked off by a fine line (lorae discrete), as in fig. 9. The 

 genae ( Wangen) are largely occupied above by the eyes. Be-
