AGEILUS. 63 



clypeus and antennae are coppery. The thorax has the impression on the disc narrow 

 and shallow in front, much broader behind, deepest a little behind the middle, and at 

 this part is closely rugose ; the surface on each side of the impression is marked with 

 not very closely placed punctures and some obscure undulating transverse lines. Each 

 elytron has the base occupied by a shallow, finely punctured sparsely pubescent impres- 

 sion ; the rest of the surface of the elytra is shining, and the punctuation is fine and 

 irregular, except at the side below the shoulder where the surface is slightly roughened ; 

 the subcosta is smooth and not much raised ; in the sutural area there are three pairs 

 of white pubescent spots — the first pair just before the middle, the second at the middle, 

 and the third near the apex ; at the side rather behind the middle there is a small 

 transverse spot ; and each elytron has about six strong acute teeth at the apex. The 

 prosternum is closely and finely rugose-punctate ; the episterna are finely punctured 

 and clothed with white pubescence. The metasternum is sparingly and very delicately 

 punctured, but has an elongate finely punctured and pubescent stripe near the side. 

 The metathoracic episterna are smooth and shining in the middle, but punctured and 

 pubescent at the base and sides. The abdomen is very delicately and not closely 

 punctured ; but at the sides of the basal segment the punctures are rather stronger, in 

 places arranged in curved lines.

The head has two somewhat round nodes between the eyes at the upper part, and 

 two lower down on the face, all distinctly and moderately closely punctured. The 

 thorax at the sides is somewhat rugulose ; the anterior margin is closely and rather 

 strongly punctured ; the raised surface of the disc, round the discoidal fossa, is smooth, 

 except a few punctures on each side of the middle ; the lateral margins are tinted with 

 violet. The elytra have a somewhat deep impression at the base of each, and there is 

 a very shallow impression at the suture a little way from the base, another at the 

 middle, and a third behind the middle ; these three impressions are very slight and 

 partially confluent ; the very short greyish-white pubescence forms two small approxi- 

 mate rings close to the suture, at one quarter from the base ; there is a broad fascia 

 behind the middle (composed of numerous pubescent spots), and a similar fascia near 

 the apex ; the parts occupied by the pubescent spots are finely punctured, the rest of 

 the surface is smooth ; in some aspects the surface has a bronzy tint.
