THK LADY BEETLES. 533 



this and nowhere else, consumiiig the epidermis and parenchyma 

 and leaving- the veins and nervnres almost intact. Hand picking ol' 

 the adults and large egg- clusters is the l)e-it remedy, if done when 

 they first appear; arsenites, either dry or in solution, can also be 

 applied with sneeess. 



Ti-ibe VIII. C(JCCIDULIXI. 



Small puliescent species having the antenna' long and slender, 

 with loose, serrate. 3-jointed club; thorax narrowed at base, feebly 

 sinuate at apex ; prosternum bicarinate, rather widely separating 

 the coxa;; legs free, rather stout; claws feebly bifid. One- genus is 

 loiown.

Family XVII. ENDOMTCHID.E. 



The Handsome Fungus Beetliss. 



To this family belong a limited number of small-sized, oval or 

 oblong beetles, which occur on woody fungi, in decaying wood or 

 beneath fogs and bark. Some of them are very prettily marked 

 with black or red, and most of them feign death or "play possum" 

 when first uncovered. The name of the typical genus, Endomijclius, 

 is derived from two Greek words, meaning "within" and "a con- 

 cealed place," and probably refers to the concealed habitations of 

 the beetles and their larvae in the substance of tree fungi, rotten 

 wood, etc. They differ from the Coccinellida\ to which they are 

 the most closely allied, by having the form usually less convex and 

 more elongate, in having much longer antenna?, and by the terminal 

 joint of the maxillary palpi being oval or triangular instead of 

 securiform or hatchel -shaped.
