aa. Third joint of antennae scarcely longer than half the second; eleventh 

 longer than ninth and tenth together ; head with three punctures 

 each side ; length 2.5 mm. 704. pusio. 



703 (2096a). Heteeothops eusculus Lee, N. Sp. N. Amer. Col., I, 18G3, 35". 

 Head black, elytra and abdomen reddish-piceous ; thorax, legs and three 



basal joints of antennae paler. Antennae longer than head and thorax, the 

 last joint obliquely truncate at tip. Thorax as wide as long, narrowed in 

 front, sides nearly straight; base broadly curved. Elytra together slightly 

 longer than wide, rather finely, not densely punctate. Abdomen more dense- 

 ly and finely punctate. Length 3-4.5 nun. 



Wolf Lake. Lake County, March 18. Rare. Listed as a variety 

 of fumigatus, but if the two are distinct the name fusculus has 

 priority. 



704 (2097). Heterothops pusio Lee. New Sp. N. Amer. Col., I, 1863, 35. 

 Head black, shining ; thorax piceous ; elytra, abdomen and antenna^ 



dark reddish-brown, pubescent ; legs dull yellow. Antenna? not longer than 

 head and thorax, eleventh joint as long as ninth and tenth united. Thorax 

 as wide as long, narrowed in front, base broadly curved. Elytra slightly 

 wider at base than thorax, rather finely and densely punctate ; abdomen 

 at base a little narrower than elytra, thence very feebly tapering to apex, 

 very finely and densely punctate. Length 2.3-2.5 mm. 



Throughout the State, common ; especially so beneath the dead 

 leaves surrounding old beech logs in dense lowland woods. April 

 17-November 28. The basal joints of antenna? and last segment of 

 abdomen are usually pale. 



XXIX. Quedius Steph. 1831. (L.. ' 1 filth + to eat.") 



Medium-sized black or brown, linear or spindle-shaped species, 

 having the labrum either acutely notched at middle and hence bi- 

 lobed. or entire and broadly curved or truncate in front; head 

 marked each side with at least four punctures, one at base of an- 

 tenna?, two above and one behind each eye ; thorax usually narrowed 

 in front, the disk with sides denexed toward the front angles and in 

 all species, except ferox and vernix, with a "dorsal row" of three 

 coarse punctures each side of middle of apical half ; often also a sec- 

 ond row between these and the margin and other smaller ones along 

 the apical and basal margins. Nineteen species are known from 

 the United States, ten of which have been taken in Indiana.
