ovipositor of species of the genus Parandra Lat. is unlike the fleshy 

 ovipositor of most of the Cerambycidse as it is heavily chitinized 

 and highly specialized, being adapted to actually insert the eggs in 

 wood. The ovipositors of species of the genera Spondylis Fab. and 

 Scaphinus Lee., however, more closely resemble those of the nor- 

 mal Cerambycidse. The ovipositor of Parandra brunnea Fab- 

 (fig. 1) is operated, by being extended by the contraction of the 

 muscular attachment of a chitinous rod and an invagination, ster- 

 nite VIII. The 8th abdominal tergite overlaps the 7th and the 

 rod and sheath is attached by muscles to the 7th tergite and the 

 8th sternite. The function of the ovispositor, which terminates in

three pair of up-pointing prongs or teeth, the inner pairs or molars 

 of which are movable, is probably to drill or rasp out a pocket for 

 the egg. The muscles at the base of the ovipositor enable it to be 

 twisted about. The ovipositor of Prionus laticollis Drury (fig. 2) 

 is also chitinized and is a modification of the normal fleshy oviposi- 

 tor of Cerambycids. 



The nomenclature is omitted as Dr. Hopkins and Dr. Boving 

 will later correlate the various parts of the ovipositor of Parandra 

 brunnea Fab. 



The eggs of Parandra brunnea Fab. are inserted in decaying wood 

 or even in moist wood where there is only incipient decay. A 

 chestnut telegraph pole in which eggs were found was set in the
