The antenne are equal to two-thirds of the elytra in length; the last joint is just the length of the three 
preceding joints united together; the basal joint is broader than long; the breadth of the sixth joint equals 
the length of the second, third, fourth, and fifth joints united together.

vertice inter oculos planiusculo, impressionibus duabus parum profundis levibus notato; prothorace subcordato- 
truneato, lateribus caput versus latioribus rotundatis, marginatis, disco canali medio notato; tibiis anticis apice

simulantibus) ; pygidio punctatissimo.

The length of the antenne equals that of the head, prothorax, and twice the scutellum; that of the 
terminal jomt equals the seventh, eighth, and ninth joints; the breadth of the antenne in the middle of 
the clava nearly equals one-third of their entire length. The length of the elytra is nearly thrice that of the 
prothorax. 
Iam indebted to Dr. Howitt for the specimen of this species here described ; it is given as distinct from 
A. MacLeayii on his authority, he having compared it with the type specimen of that species in Mr. MacLeay’s 
Collection.

vix semicireulari articulos octavo et nono longitudine «quanti; capitis angulis posticis pone oculos vix 
lateraliter porrectis ; vertice subconvexo, vix biimpresso; prothorace subcordato-truncato, lateribus marginatis,

The antenne are equal in length to the head, thorax, and scutellum ; the terminal joint is scarcely semi- 
cireular, being only equal to the two preceding in length. The basal joint is deeply emarginate for the reception 
of the second joint; the elytra are thrice the length of the prothorax, and their width nearly equals half their 
length. The width of the middle part of the clava of the antenne is equal to the length of five of its inter- 
mediate joints united.
