Smaller than angulata, Say. The lateral dark patches 

 and the discoidal mark do not touch the margin or base, 

 the disc on each side and the pleural fold are orange-red. 

 The sutural, discoidal and outer nervure are raised, the 

 two inner obscurely testaceous.

Mots, describes the pygidium of the 9 as " triangular, 

 truncate and feebly sinuate." Lacordaire says it is 

 " strongly trilobed in both sexes." Neither description 

 is exact. This segment varies in the different species, 

 and in giganteus {■= splendida, Lac, Fabricii, Cast.) 

 that of the 9 has three large angular lobes, the middle 

 being the most prominent, while in the $ it is trans- 

 versely square, the hind margin simply sinuate. (Plate, 

 fig. 15.)
