with Descriptions of some New Species. 389 



new species. To this genus belongs the Anisocerus of Hope*. 

 The name Catogenus has the claim to priority. 



Fabricius in the genus Cucujus describes four insects re- 

 ferrible to one or other of the above genera ; but unfortunately, 

 little anticipating the capture of several kindred species, he 

 has not described them with sufficient accuracy to establish 

 their identity without a comparison of specimens. 



Did not these subdivisions exist I should scarcely be in- 

 clined to propose them ; however, I think it better not to 

 undo hastily what has been done with care. I shall not hesi- 

 tate to employ them. 



Genus Passandra, Dalman. 

 Linear, depressed, and in habit somewhat resembling Pas- 

 salus ; head porrected, of nearly the same breadth as the pro- 

 thorax, and having a deep transverse posterior furrow ; eyes 

 small, lateral, roundish, and but little prominent. The an- 

 tennas are 11 -jointed, rather more than half the length of the 

 body, and inserted near the base of the mandibles ; the 1st 

 oint is stout and obovate, the second short and almost sphe- 

 rical, the remainder are nearly equal, obconic, rather com- 

 pressed, and each produced at its apex interiorly ; the last 

 joint is larger than the rest, more compressed and obliquely 

 truncate. The head is impressed posteriorly by a very deep 

 transverse furrow. The tarsi are 5-jointed, but the basal joint 

 is very short and nearly obsolete f. 



Sp. 1. Pass, sexstriata. (Corp. long. 1*4 unc. lat. *4 unc.) 



,, Dalman, Schonherr's Syn. Ins. Appen- 



dix, p. 146. 

 Head, prothorax, femora, and entire underside obscure red, 

 the other parts black and shining. The head has a deep trans- 

 verse furrow parallel to the anterior margin of the prothorax ; 

 at each posterior angle of the head this is joined by a longitu- 



* But not Isoceras of Illiger as quoted by Mr. Westwood in the ' Zoolo- 

 gical Journal,' and by the Count Dejean in his ' Catalogue des Coleopteres,' 

 Isocerus being merely a synonym of Parandra. 



f The instrumenta cibaria of each genus have been carefully and elabo- 

 rately described by the author who has proposed it. I do not repeat them, 

 finding the three descriptions nearly identical, having nothing additional to 

 offer, and considering moreover that they are by no means essential to the 

 object of this paper.
