Much rarer than emarglnatus ; at first in the spring v.ith Myrmica rubra

with Formica riflbarbis and fusca (?) (Jae^erspris, Brede, J0rholms-Common,

The Myrmedonia belong to the most considerable and beautiful staphyli - 

 nids in this division, remarkable inter alia, by the structure of the mouth- 

 parts and the socalled myrmecophlle mode of living of most of the species. 



The body is proportionately robust, rather broad, most often of even 

 breadth; the head (Fig. 31) posteriorly rounded off and somewhat constrict- 

 ed, the constricted part short and more than half as broad as the head; 

 the antennae robust and rather long, more or less thickened distally, their 

 third joint longer than the second; the eyes rather large, somewhat prom- 

 -inent, by the rather broad, most often distinctly marginated jenae sep- 

 arated from the mouth-corners, v/hich reach far back, often beyond the pos- 

 terior margins of the eyes. The outer lobe of the maxillae, the galea, 

 is extraordinarily and peculiarly long, much longer then the inner lobe, 

 lacinia; maxillary palpi long and slender, their last Joint very small, 

 subuliform; the tongue narrow, cleft at tip; labial palpi slender. 



Pronotum varies in form; elytra as long as or longer than pronotum, 

 their posterior margin inside inside the outer corners feebly inoucved; 

 abdomen broad with high margins, it^ first three onLircxy exposed (free) 

 dorsal joints depressed at base. The middle coxae are (in our species)
