BEETLES OF THE GENUS MYOCHROUS — BLAKE 31 



Remarks. — This is one of the reddish-brown species with pale yel- 

 lowish or brownish scales. It resembles M. magnus Schaeffer but is 

 a more coarsely punctate species with a shorter aedeagus, which, how- 

 ever, is very similar to that of magnus in the shape of its tip. Most 

 of the specimens in the National Museum collection are without exact 

 locality labels, having been taken at ports of entry in shipments of 

 bananas. It would appear that the species ranges from Mexico to 

 Panama.
