 guli subvotunda apicali Isvte stramineis : scutcllum eloiigatum,

Inhabits Demerara. Three s])ecimens of this lovely insect were 

 taken by M. Schombm-gk, who kindly allowed me to describe and 

 name the species. The entire colour is pitchy black, with the exception 

 of three large spots on each elytron of a beautiful straw colour : of these 

 spots the first is humeral, transverse, and extends from the costal mar- 

 gin to the scutellum, but does not quite reach the base ; the second is 

 median, transverse, and reaches the costal but not quite the sutural 

 margin ; the third is nearly apical, almost round, and does not reach 

 either of the margins ; the prothorax is rugose, and has five dorsal 

 protuberances arranged thus, .'.•. ; the scutellum is elongate, linear, 

 narrow, and has a longitudinal impression, it is of a clear pitchy black. 

 This description was read before the Entomological Society of Lon- 

 don, in 1839.
