latiori, supra obsolete (vix perspicue) punctulato, supra 

 aequali (foveis sublateralibus exceptis), lateribus ante 

 medium baud (pone medium fortiter) sinuatis, angulis 

 anticis fere rectis subproductis postis obtusis bene defi- 

 nitis, basi tota subfortiter elevato-marginata ; elytris 

 nitide minus subtiliter crenulato-striatis,- interstitiis kvi- 

 ter convexis coriaceis vix manifest-e punctulatis ; pygidio 

 sparsim minus subtiliter (metasterno ad disci latera sat 

 fortiter) punctulato ; unguiculis sat magnis ut 0. Kingi, 

 Har., ad basin abrupte curvatis. Long., 4-J 1.; lat. 2f 1. 

 The presence of a distinct raised edging along the base 

 of the pronotum places this species in Group V. in my tabu- 

 lation of Oiithophagus (loc. cit.J, where it falls beside 0. 

 Helmsi, Blackb., and 0. Koehelei, Blackb., from both of which 

 it is distinguished by its very much larger size and inter alia 

 by the absence of distinct punctures on its pronotum. The 

 adoption of the sculpture of the base of the pronotum as the 

 character on which to found primary divisions of Onthopliagus, 

 dlthough the most satisfactory that I can find, undoubtedly 

 divides into separate groups some species that seem more suit- 

 ed from their general appearance to be placed near each 

 other, and the present insect furnishes a case in point, as 

 the species to which it bears most resemblance are in Groups 

 IV. and VI., especially Kingi, Har., parvus, Blanch., Miir- 

 chisoni, Blackb., suhmiiticAis, Blackb., inermis, Macl., and 

 muticus, Macl., from all of which, except Murchisoni, it is at 

 once separated by the emarginate apex of its clypeus ; while 

 from Murchisoni, besides the character already mentioned, it 

 differs, inter alia, by the structure of its hind claws. T am 

 doubtful of the sex of the type of this insect, but consider 

 it to be probably a female, as its front tibi« are only mode- 

 rately slender and the teeth of their external margin are 

 extremely long and stout.

SYSTELLOPIDES. 

 I have recently received two species appertaining to this 

 subfamily, of which one agrees with the diagnosis of the genus 

 TricJielasmus, the other with that of Enaniillus. The distinct- 

 ness, inter se, of those two genera is based upon the number 

 of joints in the antennal flabellum, — a character that seems 

 to me of no value at all from a generic point of view, — and 

 I am convinced that they ought to be regarded as represent- 

 ing only one genus. As, however, I have not seen either of 

 the species for which the names were proposed it would be 

 unwise actually to suppress either name at present and there-
