Elongate-oblong. Color much as in longulus, the hind lobe of pro- 

 notum in great part darker; corium with hind margin rather widely 

 black, and a conspicuous small oval white spot near inner apical angle; 

 hind margin of metapleura white. Antenna? as in longulus, the apical 

 joint only fuscous. Pronotum subglobose, front lobe exclusive of collar

Dunedin, Palmdale, R. P. Park and Ft. Myers, Fla., Nov. 24 — 

 April 22. Frequent about Dunedin, especially in or about wet 

 hammocks and margins of ponds. Hibernates in dense masses 

 of the climbing milkweed, Metastelma scoparium Michx., and 

 other vines, and in spring taken by sweeping ferns and other 

 vegetation in the hammocks. Recorded from numerous other 

 stations in Florida and doubtless occurs throughout the State. 

 Our smallest member of the genus, ranging from North Caro- 

 lina to Texas ; also known from the tropical regions of the 

 Old and New Worlds and the Pacific Islands. The Rhyparo- 

 chromus parvulus Dall. (1852,576) is a synonym. Uhler (1876, 

 310) says that in Hayti "it occurs in small swarms upon low 

 plants in damp spots and in gardens."
