Onaffra biennis. — In addition to the larva of the web tube 

 previously mentioned, this was fed upon by Attelabiis bipustu- 

 /afiis, Halfica fiiscocenea, Tyloclerma foveolatiini, and Cha/coder- 

 iiuis roffaris, and often harbored a numlier of adult Metnrhmma

Momirdd piiniiata. — This abundant plant of the sand re- 

 gions about Havana was seen at different times to have its 

 stems dotted with CoriinelcviKi cilicita and Schinis rincfits. The 

 Coriiiu'/iciKi, usually considered quite a rare species, was also 

 extremely abundant in nearly bare sand about the bases of lit-

(Jo)iiw('liii(i rirginica. — The leaves of this plant were white- 

 streaked by the feeding of adults of Lftna connifd. the larva of 

 which bores in the stems. 



B/iKS (ironiutica. — This dense, bushy sumac (PI. XIX.) sup- 

 ported Bhpltaridii rhois and its sticky larvae, Periling cirann-

Eifpliurbiii roroUata. — Chariesterus untennafor was once

Cassia rliainarrisfa. — This common flowering plant of the

 from it in numbers, probably breeding in the seeds. 



Cracca liryiniana. — A group of these plants was infested 

 with Macrobasis unicolor. 



Callirlioe friani/ulafa. — This formed a sprangling tuft of 

 stems and long-petioled radical leaves, and at their extreme
