COLEOPTERA. 38 1 



second and thii-d joints of the antennse resemble reversed cones, almost 

 of the same thickness ; the following ones are granulous. 



Some have two teeth on the exterior side of the intermediate 

 tibise. 



Sc.pt/racmon, Bonel.; Dej., Spec. I, p. 367 ; Sc. gigus, Oliv., 

 Col. HI, No. 36, I, 1 ; Clairv., Entom. Helv, II, ix, a. About 

 an inch long ; apterous ; flattened ; of a shining black ; the elytra 

 somewhat widened posteriorly, finely striate, and the striae 

 lightly punctate ; in the third, near the extremity, two more dis- 

 tinct and deeper puncta. The head, according to Count Dejean, 

 is much larger in the male than in the female ; the front of 

 the latter presents two impressions and some little rugse. The 

 thorax, on each side, exhibits a tooth posteriorly. There are 

 three on the anterior tibiae. It is found on the borders of the 

 Mediterranean, in the south of France, and the eastern part of 

 Spain. M. Lefevre de Cerisy, a distinguished naval officer 

 and excellent entomologist, has published some observations on 

 its habits. 



Sc. terricola, Bonel.; Dej., Spec. I, p. 398. Body furnished 

 with wings ; from eight to nine lines in length ; black ; anterior 

 tibice with three stout teeth, followed by three very small ones ; 

 external side of the two following tibiae with but one ; elytra 

 elongated, striate, and slightly rugose ; two deep points near the 

 third stria. Found with the pyracmon. 



Sc, sabulosvs, Oliv., Col. Ill, 36, 1, 8 ; Clairv., Entom. Helv. 

 II, ix, 6 ; Scar. Icevigatus, Fab., Dej. Very similar to the ter- 

 ricola, but somewhat smaller and more depressed ; it is apterous 

 and the elytra slightly striate ; but two indentations on the an- 

 terior tibije after the three ordinary teeth. It inhabits the same 

 localities as the pyracmon, and is also found in Sicily («). 



OXYGNATHUS, Dcj. 



The Oxygnathi, as to their antennae and palpi, are essentially simi- 

 lar to the preceding Insects, but having, as well as the two following 

 subgenera, long, narrow, edentated mandibles which cross each other 

 in the manner of a forceps. Their body is narrow, elongated, and cy- 

 lindrical ; their antennae shorter than the head and mandibles united ; 

 the labrum rather indistinct, and the thorax almost square. 



The t}'pe of this subgenus — Scarites elongatus, Wiedem. ; 

 Oxygnathus elongatus, Dej. Spec. II, p. 474 — is from the East 

 Indies. 

 There, the four exterior palpi, or at least those of the labrum, ter- 



^S^ (a) The Sc. suit err aneits, [Fab. 'Syst. El. I, p. 124, No. 8, 'usually] consi- 

 dered as the only species of Scarites, — inhabits the United States. The very great 

 disparity of size, however, between it and a congener from Georgia, combined 

 •with a certain difference of aspect would seem to warrant the supposition that the 

 latter is a distinct species. Although, after the most careful comparison of the two, 

 I confess my inability to point out any truly specific difference, I am still inclined to 

 believe they are distinct.
