and acutely angulate at their apices ; lateral margins oblique, 

 moderately laminate and very finely crenulate, lateral angles sub- 

 prominent ; posterior margin nearly straight ; anterior margin 

 excavated for the reception of the head, behind which it is truncate. 

 Scutellum more than half the length of the abdomen and narrowed 

 before apex which is rounded ; membrane not quite reaching apex 

 of abdomen, with longitudinal veins ; rostrum reaching the inter- 

 mediate coxfe, basal joint almost extending to base of head ; meso- 

 and metasterna somewhat obscurely furrowed ; antennae, tibiae, and 

 tarsi distinctly pilose.

Division DYM ANT ARIA *. 



This diA'ision includes a group of genera separated by Stal (En. 

 Hem. V, p. 51, 1876) and some others placed by him in another 

 category. The following characters represent the division as 

 understood and proposed here : — The antenniferous tubercles are 

 remote from the lateral margins of the head, and inside longitudinal 

 lines through the inner margins of the eyes ; the head is always 

 elongate, sometimes longer than broad ; tlie sternum is usually 

 sulcated ; and the odoriferous apertures are often, to use a term of 

 JStal's, " subauriculatae." 



* The genus Dymantis, on which the divisional term is constructed, is 

 African.
