tended for the same purpose as the tufts of hairs on the abdomen of 
the genus Claviger, which are known to be sucked by the ants; even 
in Lomechusa there are similar hairy appendages on the sides of the 
abdomen. Of this genus only one species is known to me (Spi- 
rachtha Eurymedusa), of about 2 millim. in length, from the front 
to the end of the second segment of the abdomen. 
In the abdomen of both genera I have found eggs in different 
stages of development, in Corotoca even eggs with fully developed 
larvee ; so that, beyond doubt, these animals are viviparous. 
If the Strepsiptera are to be considered as belonging to the order 
Coleoptera, an opinion which I endeavoured to prove as early as the 
year 1840*, this will be the second instance of viviparous Coleoptera.
