rmly held between tw> saws; the apparently U 

 bent back into a groove in the tibia. Another striking char., 

 is ])resented by the antenn;e : the terminal segment is more or 

 enlarged into a knob. Under the lateral margin of the pronotum 

 there is <>n each side a groove into which the antenna fits. 



Only two genera are represented in our fauna. These can be 

 distinguished as follows: 



^cuiellum short; head with a bifid prolongation above the insertion of tin- 



I'm 



A.\. Scutellum very lonjj. rxu-ndin.u; to the tip of the abdomen ; head \vithout 

 bifid prolongation of the antem M.\< 



Our most common species is Phyinatii Wolffii (Fig. 169). It is 

 a yellow insect, greenish when fresh, marked by a broad 

 ~^~ black band across the expanded part of the abdomen. 

 It conceals itself in the flowers of various plants, and cap- 

 j^^l lures the insects which come to sip nectar. It is remark-

 Cabbage-butterflies, honey-bees, and large wasps 

 overpowered by it.

The Arniliilic ai :ii/ed by the (U-]>ressed form 



of the body. In fact they are tlu- flattest of all Heteroptera. They 

 live in the .ith the bark of decayin and the 



form of the body is r^jx -eially adapted fr gliding about in tl 

 cramped situations. They are usually of a dull brown color; >ome- 

 tini' re varied with reddish or pale markings. Unlike the pre- 



family, the similar form. There are no 



ocelli; the antenna- are four-jointed; the rostrum three-jointed ; the 

 wing-covers are usually well developed, with distinct corium. davus.
