 " Caput maris supra angulato-elovatum/^ While accept- 

 ing the genus Fsetidolucanns proposed by Mr. Hope for 

 atratus and capreohis, in which I include the insect under 

 consideration^ as well as Barharossa, I attribute but slight 

 importance to the character given by Mr. Hope (since 

 in the var. minor of the males of many species of Liicaims, 

 it is altogether absent) ; but characters may be mentioned, 

 which so far as my experience extends, are subject to 

 little or no variation, viz., the size and form of the man- 

 dibles. With regard to size, I find on a careful exami- 

 nation of numerous specimens of the several species in- 

 dicated, that the mandibles seldom exceed the length 

 of the head ; and with regard to form, that they are always 

 strongly curved, and never present on their inner edge 

 more than one tooth. I am therefore strongly inclined to 

 believe that these characters will prove to he constant, 

 and that they represent the normal condition of these 

 organs, whereas, in those specimens representing the var. 

 minor of their respective species, their mandibles ai-e 

 porrect, and their internal armature invariably multi- 

 dentate. The number of the joints in the clava of the 

 antennee varies in Pseudolucanus as it does in Lucamis, 

 P. Barharossa exhibiting six, while each- of the other three 

 species, P. atratus, P. capreolus, and P. Mazama exhibits 

 only four. 



P. Mazama differs from the allied species of the genus 

 in its broad and exceedingly short clypeus, which is 

 slightly concave, in the angles of the head behind the 

 eyes being more prominent, in the anterior angles of the 

 prothorax being very much produced, and finally in its 

 punctuation, which is uniform on the entire sui'face, and 

 although diffuse, is strong and very apparent ; the colour 

 of the insect is dull rufous; it is, I believe, unique in 

 Dr. Leconte's collection. The $ is still unknown. 



Dorcus hrevis, Say. 



With respect to the insect noted as Dorcus hrevis of 

 Say, I have, after most careful examination and compari- 

 son with numerous specimens of Dorcus parallchis, Say, 

 a not uncommon North American species, arrived at the 

 conclusion, that the specimen in question must be con- 

 sidered as only an old worn state of D. paraUelus in which
