1S4 Mr. G. Lewis on 



This species is larger than A. taciturnus, Mars., and it has 

 three inner apical dorrfal strias, which are wanting in Marseul's 

 .species. The firm of the rnesosternum is like those of 

 A. taciturnus, Mars., and A. latiusculus, Sch., although 

 Marseul s.iys (Mon. p. 244) that the rnesosternum »{' taciturnus 

 is without a marginal stria, meaning that the stria along the 

 border is incornj)lete.

Oblong-oval, somewhat depressed, black and sliining ; the 

 head smooth and the forehead concave, with a fine transverse 

 stria which is sinuous in tiie middle ; the thorax, the marginal 

 stria is very fine, the lateral is also somewhat fine but well 

 marked, and it continues along the base to a point opposite 

 the third dorsal stria, anteriorly it is inteirupted behind the 

 middle of the neck ; the elytra, there are two fine sinuous 

 epij)leural striae, the dorsal, 1-2 complete and Avell marked, 

 3 finer and interrupted in the middle, the humeral and other 

 striai are wanting ; the propygidinm is transversely punc- 

 tured, but smooth along its edges; the |)ygidium is wholly 

 punctured, there is a de^u'ession on either side at the base, and 

 the outer rim is smooth but not much raised; the prosti'inuni 

 is smooth and somewhat truncate anteriorly and the lobe is 

 clearly marginate ; the mesosternum, the marginal stiia is 

 interrupted at the emargination ; the anterior tibite are 

 4-dentate. 



The lateral thoracic stria continuing along the greater 

 ])ortioii of the base constitutes a good specific cliaracter.
