AMERICAN COLEOPTERA. 363 



This may be the insect indicated by Motschulsky, as JJygrotophila 

 testacea from Georgia. 



As a supplement to the preceding paper I wish to record the occur- 

 ance of the genus Myrmeeoxenus, Chev., in the United States. It re- 

 sembles Mycetsea in some respects, having 4-jointed tarsi, but the 1st 

 joint is longer than the second; the anterior coxal cavities are closed, 

 the antennae 11-jointed with a 5-jointed club, the 2d joint is not 

 larger than third. Epipleurge extending to the apex of elytra, py- 

 gidium exposed. The whole facies is that of a Gort.icaria. 



W. latridioides, sp. n. — Elongate, reddish-brown, finely pubescent, tho- 

 rax quadrate, sides crenulate, closely punctulate; elytra with the sides rounded, 

 more visibly punctulate than the thorax; prosternum roughly punctate; ven- 

 tral segments black, punctulate. L. '7 inch. 



This genus ouyht to be placed in the Mycetophagidx ; it is found 

 in ants nests and about hot-beds in Europe.
