The small insects which constitute the genus Lithocharis may be knowTi by 

 their more or less ferruginous, closely jjunctulated and finely pubescent bodies, 

 by their largely-develoi^ed wings (with which they are for the most part exceed- 

 ingly active), by their either subquach-ate or triangular- quadrate heads and squarish 

 prothorax, by their denticulated upper-lip, and by the joints of their four hinder 

 tarsi (the ultimate one excepted) gradually decreasing in length. They are found 

 either beneath stones or dead leaves, but (with a few exceptions, — as, for instance, 

 the L. melanocepliala, which is principally attached to the mountain districts) are 

 more frequently perhaps to be captured on the wing, especially during sunshine 

 after showers, than under other circumstances. They are widely distributed over 

 the world, — the hitherto discovered species being in about equal proportions from 

 Eiu'ope and America. 



460. Lithocharis fascnla. 



L. rufo-ferruginea subnitida, capite magno oblongo-quadrato piceo et dense ruguloso- punctate, oculis 

 minutis, prothorace subtilius punctulato postice leviter angustato, elytris interdum bine indc 

 infuscatis, abdomine obscuriore, antennis pedibusque pallido-ferrugineis.
