STALAGMOSÜMA BALIOLA. 109 



collection , evidently only a variety of this species , has 

 the disc of the thorax, the pygidium and the apex of 

 the abdomen red, there is also an indication of a red spot 

 on the elytra near the suture behind the middle. The two 

 specimens in the Leyden Museum are of the type form. 



S. alhella has been separated as a distinct genus by Dr. 

 Kraatz under the name of Stalagmopygus ^ but the diffe- 

 rences given to distinguish it from Stalagmosoma (such as 

 the absence of a third minute white spot on the pygidium) 

 appear to me to be too trivial as generic characters. 



Leucocelis franki^ n. sp. 



Head black ; closely punctured , the punctures confluent 

 and forming striae on each side between the eyes, slightly 

 convex in the middle , apex of the clypeus reflexed and 

 slightly emarginate in the centre; antennae red-brown. 

 Thorax red with a blue or green tinge , the anterior mar- 

 gin , a small spot on each side , a large longitudinal spot 

 in the centre and an ill-defined transverse mark in front 

 of the scutellum black or green, with a bluish tinge; strongly 

 rounded at the base on each side , straight in front of 

 the scutellum , slightly narrowed from the base to the 

 middle, thence rounded and narrowed to the apex, the disc 

 rather finely and sparsely punctured , the punctures coars- 

 er towards the sides. Scutellum black or green , impunc- 

 tate, the apex very acute. Elytra red tinged with blue,

 er spots near the suture and outer margin and on the 

 disc white; ten rows of coarse punctures on each elytron, 

 the first and second rows assuming striae behind the middle ,
