striae rather crenulated than punctured, the 6th and 10th 

 interstices, as well as the suture, being more elevated. 



Motschulsky states that it bears the same analogy to 

 arvensis as Menetriesii does to granulatus. If so, it would 

 seem to be entitled to consideration, as Menetriesii appears 

 universally admitted to have specific value.

 Deutschl., i, 537; D. Sharp, Ent. Mo. Mag., v, 196. 



Dr. Sharp notes that the insects representing A. ingenua 

 in our collections, and taken by Mr. A. Adams at Swansea, 

 must be referred to this species ; but that A. ingenua may 

 possibly be British, as Mr. Dawson, Geod., Biit., 125, re- 

 cords its occurrence also in Scotland. Dr. Sharp, who has 

 had considerable experience in Scotch collecting, remarks, 

 however, that he has never seen a Scotch specimen of that 

 insect. 



A. fusca appears to differ from A. ingenua in being con- 

 siderably flatter and of more parallel form, with lighter an- 

 tennae and legs, a less robust head, but much more prominent 

 eyes, the thorax less transverse, the elytra less strongly 

 striated, &c. 



Mr. Dawson, with whom I have communicated on the 

 subject, tells me that he possesses a single Scotch specimen 

 (taken by Mr. Little) of the A. ingenua of Geod. Brit. 

 (wherein it is stated to agree perfectly with examples of 

 A. ingenua from Paris), and kindly promises to send it to me 

 for examination. The Swansea specimens are identified with 

 this Scotch example by Mr. Dawson, Ent. Annual, 1858, 

 p. 53 ; and I should, therefore, imagine there is but little 

 chance of the latter being true ingenua.
