MICROPHYSID.E. 483 



brown-black ; below the cells, and extending to the apex, a darker, 

 somewhat oval patch ; inner marginal and cell-nerves pitchy black ; 

 cells black-brown, the outer one margined exteriorly with black- 

 brown. Sternum black. Legs ferruginous ; tibice with short, black 

 somewhat spinose hairs ; tarsi and claws black. 



Abdomen black underneath, clothed with very short, fine, whitish 

 hairs. 



Length, 1^ If line. 



An abundant species at Scarborough, amongst the short grass on 

 the tops of the cliffs ; also on the flowers of Vicia craoca in July 

 (Wilkinson) ; Mickleham (Dr. Power). 



NOTE. For the most part the insects composing this section, 

 especially those that are green, fade much in colour after death. 

 All have been described from specimens with their wings ex- 

 panded, as without this being done their true characters cannot be 

 ascertained, because the different colour of the upperside of the 

 abdomen shining through changes their natural appearance. In 

 describing the breadth of the head in proportion to its length, it has 

 always been done from a vertical point of view, and with reference to 

 the natural position of the head. 



SECTION IQ.ANTHOCORINA* 

 FAMILY 1. MICROPHYSID^E. 



Genus 1. MYRMEDOBIA, Bar ens. 



Head broad, short, convex, 5-sided ; or, including the eyes, sub- 

 triangular ; Face projecting, deflected ; sides at first parallel, then 

 divergent in a curve ; central lobe broad, short, obtuse ; side lobes 

 narrow, triangular, almost as long as the central lobe ; cheek plates 

 projecting as far as the end of the central lobe. Antenna slender 

 (in the <$ longer and stronger than in the $ ) ; 1st and 2nd joints 

 slightly thickest, the 1st not \ so long as the 2nd, in the <$ reaching 

 beyond the end of the face ; 2nd and 3rd in length subequal, the 

 base very slender, the 2nd slightly thickened towards the apex ; 

 3rd and 4th filiform, 4th slightly longer than the 2nd or 3rd, apex
