sutural groove instead of a raised line in the frontal part ; it is not 

 so spherical as A. emeritus, which is really its nearest ally, and from 

 which it is also distinguished by the punctuation of the prothorax 

 which is not so closely set, and by the deeply striate dorsal part 

 which plainly numbers six striae on each side ; the anterior tibiae are 

 also bi-dentate outwardly. If the genital armatures, which are on 

 the same plan, of the two species are compared, it is seen that the 

 tubular part is much more deeply notched and twists inwardly 

 on the left side in A. laetulus, the right process is sub-horizontal 

 and does not therefore act as an operculum, the inner forcipate 

 process is very short, and the apical part of the tubular part is 

 flattened into two small processes. 



Length 5^-6 \ mm. ; width 4-4J mm.

Ovate, reddish-bronze, with the elytra often greener, and with an 

 opaline sheen, antennae and palpi flavescent or rufescent, the club 

 slightly longer than the pedicel in the male ; the sharply tri- dentate 

 clypeus is not as sinuate laterally as in T. emeritus, and the upper 

 angle of the lateral constriction is very sharp ; instead of a frontal 

 suture there is a plainly raised line ; the prothorax is of the same 

 shape as that of T. emeritus, but the punctures, although equally 

 fine, are not set quite so close to each other, and the intervals in 

 the median dorsal part are not sub-strigillate ; the elytra are more 

 elongato-ovate and appear therefore less convex in proportion, in 

 nearly all my examples the four dorsal striae are distinct, and 

 as often as not there are plain traces of a fifth and even a sixth ; 

 interior tibiae bi-dentate outwardly ; this species is easily recognised 

 from its congeners by the presence of a raised line instead of a 

 grooved suture at the junction of the clypeus with the frontal part, 

 but the shape of the genital armature distinguishes it also readily, 

 the two claspers being strongly twisted, spatulate at the tip with 

 the upper one nearly erect, and the other curving upwards 

 underneath. 



Length 5f-6-|- mm. ; width 3f-4J mm. 



Fahraeus, in his description of the species, says that the anterior 

 tibiae are tri-dentate, and that with the exception of the sutural 

 stria which is impressed behind, the striae are hardly visibly striate. 

 My examples, compared with the type, are, however, as described 

 here.
