the collection of G-ueinzius and is labelled " Natal." Gfueinzius col- 

 lected near Durban ; and so far as is now known, B. longicornis is the 

 only species occurring in this neighbourhood. 



BULLA STJBALATA, n. Sp. 



(Fig. 1.) 



? . Olive green, with the crest pinkish-red but probably light green 

 in life. A robust species. Head broad, smooth ; antennae wanting 

 pronotum tectiform but with the anterior lobe very sharply serrate, 

 the posterior is almost in a line with the anterior and does not slant 

 much behind, the crest is sharply serrate to three-fourths of the 

 length, the anterior lobes are very deep, especially the hinder, the space 

 between each fold having a double series of conical tubercles ; the 

 strongly reticulate upper side is sprinkled with small tubercles,

and the membranous, deeply reticulate tegmiua are well developed, 

 cover one-third of the width of the sides and reach as far as the 

 hind point of the pronotum ; abdomen nearly concolorous in the only 

 example known to me, but a faint median line of spots is somewhat 

 discernible ; anterior femora weakly pitted, but not tubercular. 



Easily distinguished from all the other species of Bulla by the 

 small smooth head, the less tectiform pronotum, the presence of rudi- 

 mentary yet well-developed tegniiua in comparison with the other 

 females of the species of Bulla. In the ? of B. serrata there is a 

 rudiment of red tegnien, but it is extremely short and is quite hidden 

 by the side of the pronotum. 



Length 60 mm.
