Gravenhorst (Coleopt. Micropt. Pref. Ixi) after stating the 

 difficulty of attending to the manners, &c. of these Larvae at 

 different periods of their life, observes that he has occasionally- 

 found the solitary black Larvae " Speciei cujusdam majoris Sta- 

 phylinorum (S. Olentis? S. similis?) in sylvis locis enebrosis 

 suffocatis, sub muscis arborum caesarum," and which from his des- 

 cription differs but slightly from that described above. The first 

 segment of the body he observes, '' thdraci insecti perfecti res- 

 pondebatj" and the 2d and 3rd " pectori insecti perfecti respon- 

 debant." He describes the last joint of the abdomen as being 

 " subpenultimum retractum anum emittebat cylindricum, longitu- 

 dine segmenti, co autem quadruplo angustiorem et supra spinis
