division I am not certain that the genera named 

 Asteriza and Omaspides are published ; they appear 

 to afford ample characters for sub-division ; and for 

 the present, I merely adopt them provisionally. 



Omoplata, Hope. 



Type of the genus Cassida Marginata of Linneus. 

 Mandibulae, maxillae et palpi, fere ut in Cassida 

 perforata. Antennae parum compressae, pubescentes, 

 articulo lmo. crasso, 2do. minimo, 3tio. paullo longi- 

 01 i, reliquis longitudine fere sequalibus, at extrorsum 

 crassioribus. Thorax antice rotundatus, semicir- 

 cularis, reversus, postice sinuatus, ad suturam con- 

 formatus. Elytra semicircularia in medio disci 

 elevata, convexa, humeri valde porrecti, lati, baud 

 in spinam producti, apex elytrorum rotundatus. The 

 above name is derived from w/mos humerus, and 

 ttXcltvs latus. 



The characters of Oxynodera and Calaspis will 

 be found at the end of this Fasciculus along with 

 other new genera and species. Omaspidis and As- 

 teriza of Chevrolat, differ in form from Omoplata. 

 Aspidimorpha and Thyreaspis are represented by 

 the Fabrician species C. Miliaris, and 11 -punctata. 

 The details of the last will be found in Olivier's 

 work, at Plate 4, Fig. 67, b, Cassida. 



P/ecilaspis, Hope. 



The major part of the species are variegated with 

 red and yellow.
