A HISTORY OF HERTFORDSHIRE 



ALEOCHARINA (continued) 



Calodera umbrosa, Er. Wihtone, very rare, 

 one specimen only under dead reeds 

 at the reservoir. This insect occurs 

 very frequently near Chesham, just 

 over the county boundary 



Chilopora longitarsis, Steph. Tring, a 

 common marsh species 



Atemeles emarginatus, Payk. One speci- 

 men found running on chalky path- 

 way. This species is usually as- 

 sociated with the smaller ants. In 

 that portion of the county which I 

 have been able to explore I have not 

 yet noticed the large ants Formica 

 rufa and F. fuliginosa, with which 

 so large a 'number of our myrme- 

 cophilous species occur, and conse- 

 quently the number of such species 

 included in this list is very small
