G2 My. G. J. Arrow on Melolontldne Coleoptera. 



■wove cnjitiired on tlie nioniins: of Nov. 3, 1814, at Dnyker 

 Rivor, ill the soulh of Ca^ie (Juloiiy, a little to tiie west of 

 Mos>*i'l B;iy. 



The tvpe is ono. of throe spfcimen^i in tlie Brlti>ih Museum 

 ■deriveil from the Pascoe OoUection. There an^ also four from 

 the Fry Coilectiou and one from the R'iche Cellection. All 

 these, as well as the two hrou^ht hy Burchell, are males, and tlie 

 other sex remains still unknown. The species was wrongly 

 identilied with Monochchm sniuipes, F., by h'eiclie, and has a 

 general resemblance to that insect, but its .structural characters 

 are not those o\ Monocluhts. Tiiey ;igree with those formulated 

 by Mr. Peiinguey for hi.s genus Goxina, one of those created 

 by the dismemberment of the old Gi/mnohma. This dis- 

 memberment is very unsatisfactory, since by a process of 

 elimination the orijiinal cenus is left without tangible differ- 

 ential features at all. The present form, howevi r, is nearly 

 related to Gymnolonm lineolatn^ the tyfjc of Gonim, although 

 much larger and broader. Its comparatively large size and 

 Booty-black surface render it easily recognizable. 1 at first 

 euspected that the absence of scales from the upper surface 

 niijiht be due fo age; but the specimens are in general well 

 preserved, and, as all agree in being smooth on the upper 

 surface, they are evidently in their natural condition. 



Dicranocnemtis J)urcheUi, sp. n. 



Fuscous, with the elytra and legs i-eddish. Kather elon- 

 gate, the thorax distinctly longer than wide and not gibbous, 

 Clypeus parabolical, the front margin very slightly reflexed 

 and with scarcely visible angles. Upper surface of the head 

 uniformly iinely rugose and pubescent. Prothorax mode- 

 rately convex, the sides regularly rounded and converging 

 forwards. Front angles acute, hind angles obsolete. 



cJ . Prothorax finely rugose and densely clothed with 

 rather short tawny pubescence, which changes into scales at 

 the posterior margin, 'i he median sulcus is deep behind, but 

 vanishes beyond ti)e middle. The scutellum is clothed with 

 elongate whitish scales and the elytra with round scales 

 varjing in colour from chocolate to pale yellow, the light 

 ones forming a median longitudinal stripe wiiich is broadest 

 near the shoulder, a sutural stripe broadest at the apical end, 

 and a quadrate patch between these. The })ygidium and 

 propygidium are densely covered with orange scales, with a 

 darker band at the base of the former. The claws of the 

 middle feet are without a basal appendage 



Length 5'5 mm.
