galleries in the solid wood of oak, also of chestnut, maple, 

 and other deciduous trees. 



ANTHRIBID^E 



Some recent authorities use the name Polystomidse. 

 These beetles are usually found on dead wood or on those 

 fungi which grow on trees. Little is known of their life 

 histories. Eurymycter fasciatus is about .3 in. long and 

 has a conspicuous patch of white pubescence on the beak 

 as well as a broad, white band across the elytra. Brachy- 

 tarsus sticticus is not over .15 in. long, and breeds in the 

 smut of corn and wheat. Euparius marmoreus, sooty 

 brown mottled with gray, is very common on tough 

 fungus on fallen logs, .its color matching well with its 

 surroundings. 



CURCULIONID^: 



This is a very large family, more than 20,000 species 

 having been described to date. The maggot-like larvae 

 have no more than bristly elevations for legs; the front 

 part of the body is usually the thickest and, when at rest, 

 the larvae are usually curled like a C. Pupation usually 

 occurs where the larvas live but some species pupate in the 

 ground. Thirteen subfamilies are recognized as follows: 



1. Antennae straight, the beak not grooved to receive 

 them 2 ' 



Antennas more or less completely elbowed, the beak 

 grooved to receive them when at rest; antennal club 

 compact 9- 



2. Antennal club composed of completely separated 

 joints 3- 



Club composed of compactly united joints 6. 



3. Thorax without side margin 4- 



Thorax acutely margined and excavated beneath; 



three abdominal segments show beyond tip of abdomen. 

 Pterocolinae, of which only Pterocolus ovatus is known from 

 the eastern United States. It is blue, less than .17 in.
