 their fellows, that they may escape to 

 their crannies and lurking holes, to avoid 

 danger. WHITE. 



CIMEX LINEARIS. 



V 



August 12, ]775. Cimices linear cs are 

 now in high copulation on ponds and 

 pools. The females, who vastly exceed the 

 males in bulk, dart and shoot along on the 

 surface of the water with the males on their 

 backs. When a female chooses to be dis- 

 engaged, she rears, and jumps, and plunges, 

 like an unruly colt; the lover thus dis- 

 mounted, soon finds a new mate. The 

 females, as fast as their curiosities are 

 satisfied, retire to another part of the 

 lake, perhaps to deposit their foetus in 

 quiet ; hence the sexes are found separate, 

 except where generation is going on. From 

 the multitude of minute young of all gra- 

 dations of sizes, these insects seem without 

 doubt to be viviparous. WHITE.
