this and nowhere else, consuming the epidermis and parenchyma 

 and leaving the veins and nervures almost intact. Hand picking oi 

 the adults and large egg-clusters is the best remedy, if done when 

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

 applied with success. 



Tribe VIII. COCCIDULINI. 



Small pubescent species having the antennae long and slender, 

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

 sinuate at apex: presternum bicarinate. rather widely separating 

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

 known.

Elongate-oval. Head and part of under surf ace black : thorax dull yel- 

 low with a transverse black spot near apex; elytra dull yellow, black at 

 base and along sides to behind The middle and with a common transverse 

 sutural black spot at apical third. Punctures of elytra rather coarse, deep 

 and uneven, the larger ones in somewhat irregular rows. Length 3 mm. 

 (Fig. 195, d.) 



One specimen in Field Museum collection labelled Ind. 

 Probably from St. Joseph County. A species of northern range 

 which is said by LeConte to occur on plants near water. 



Family XVII. EXDOMTCHIDJE. 



The Haxdsome Fuxgus Beetles. 



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

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

 beneath logs 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. Endomych us. 

 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 Coecinellidas, 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 hatchet-shaped.
