The above genera belong to the Mesomphalidae. 

 With regard to Mesomphalidae, it might still further 

 be sub-divided into three, if not four sub-genera, 

 a task I willingly leave to others. The next 

 genus I describe and name, is Paecilaspis, from 

 7toiki\o? and a<rma scutum, as the major part of the 

 species are variegated with red and orange spots. 

 The following characters sufficiently separate it from 

 its allied genera. " Antenna submoniliformes, com- 

 pressae. Thorax semicircularis lateribus utrinque 

 rotundatis, elytris haud aequalibus postice sinuatis. 

 Elytra convexa, thorace latiora, humeris prominen- 

 tibus et tuberculatis ; apex elytrorum rotundatus. 

 Prosternum in medio fortiter impressum.*

 new genera, the reader is referred to the Annals of Natural History, 

 No. 15, published in 1839.
