others might be added. Monsieur Chevrolat, in 

 the Baron De Jean's Catalogue, has published the 

 names of at least 20 others, but as their characters 

 are not given, I cannot adopt them. The following 

 concise descriptions of some of the sub-genera which 

 appear in the tables, will separate a few from the 

 mass of nondescripts, in a family, which is remarkable 

 not only for its great variety of form, but also for 

 the abundance of species belonging to it. 



POLYSTICTA, Hope* 



Type of the genus Chrysomela guttata, Fabricius. 

 Genus Africanum, statura coccinelliformis, ovata, 

 valde gibbosa. Antennte breves. Thorax laevis, haud 

 marginatus, scutellum postice subrotundatum. Ely- 

 tra abdomine latiora, valde convexa, punctata. Corpus 

 infra contractum. Pedibus robustis. The majority 

 of the species are remarkable for the number of 

 guttae or spots with which they are ardorned ; and 

 hence I have applied the name of Polysticta. 



Gastroeidea, Hope. 



From yaspoeihfjs ventrosus. Type of the genus 

 Chry. Polygoni, Linneus. Statura ovato hemisphae- 

 rica, oblonga. Caput rotundaturn, antennis thorace 

 fere duplo longioribus. Thorax transversus latior 

 quam longior, lateribus haud incrassatis. Elytra 

 thorace triplo longiora Ovis gravida, ultra coleoptera 

 ventricosa evadit. From this peculiarity, I have 

 given the above name of Gastroeidea.
