CEROTALIS. 
The insects forming this genus have entirely the general ap- 
pearance of Promecoderus, but have no tooth to the men-

cushions below their four first articles. 
This latter character separates them from Parroa, and 
their palpi ended by an oval subtruncated article, makes 
them easily distinguished from A dotela. 
Mr. Lacordaire, in the first volume of his genera, had 
already mentioned the necessity of establishing this generic 
division for P. Degener. 
Cerotalis Seminiolacea: length 82°; of a dark copper 
colour on the upper side, and of a fine deep purple below; 
elytra smooth, with a few large, irregular, and punctiform 
impressions on the posterior part, near the margin; legs 
black; palpi brown; antenne and tarsi with hair of the 
same colour. 
Port Lincoln, South Australia. 
Cerotalis Substriata: length 73’; same colour as preced- 
ing; elytra covered with rather faint longitudinal ridges, 
forming irregular striz ; the punctiform marginal impressions 
of the elytra generally deeper. |
