of the ]H-()n<)tuni frhiged witli bright yellow hairs. The body 

 fairly sliort and depressed, the elytra with ratln^r rounded and 

 ilattened lateral margins. The prosternum a little produced 

 behhvd and not sharp. 



$. The head is short and transverse, coarsely punctured in 

 front, finely granular behmd. The clypeal process is transverse 

 and rounded. The pronotmn has a narrow smooth, shining and 

 finely ])unctured median area ; the sides are broadly coriaceous 

 and dull ; the front and liind margins closely punctured, the 

 lateral angles not very sharp. The elytra have a smootii 

 shining dorsal area and broad opaque outer margins. The 

 front tibia is broad, with very feeble teeth. 



(^. The head is long, densely granular and opaque, the front 

 angles rounded, the sides parallel, except at the base of the 

 head, where they diverge slightly. The clypeal process is bluntly 

 ])ointed. The pronotum also is densely granular and opacjue, 

 but more so at the sides and sometimes shining along the 

 middle line. The front angles are produced and fairly sharp, 

 the sides rounded to beyond the middle, where there is a sharj) 

 angle, and strongly concave from this to the very acute iiind 

 angle. The elytra are smooth and shining, with the margins 

 dull. The mentum is granular and thinly clothed with yellow 

 hairs. The legfi are long and slender, the front tibia a little 

 curved, its extremity bearing a dense tuft of short yellow hairs 

 internally and very feebly forked externally, the outer edge 

 armed with a single minute spine or none, the middle and hind 

 tibiae bearing short fringes of yellow hair at the imier edge. 



Variation of the male. — Variable phase. In small specimens 

 the head is narrow, the mandibles are shorter than the head, 

 simply rounded externally and irregularly toothed internally 

 from base to apex. The front part of the head has a gentle 

 declivity. In larger examples the declivity is steep, the 

 mandible longer, with stronger and less numerous teeth and 

 a gap appears between these near the base. In still larger 

 males the mandibles are longer than tlui head and a second 

 gap appears beyond the first tooth, which is drawn out into 

 a horizontal process. In the large specimens the head is 

 broader, especially in front, the anterior edge is straight and 

 sharply ridged, and the declivity is hollowed or abruptly 

 vertical. 



Constant phase. Amongst 42 male specimens I have 

 examined are 18 belonging to another ])hase, in which the 

 mandibles are much longer than the liead, slender, strongly 

 rounded exteinally, and without either basal prominence or 

 horizontal tooth internally, the inner edgc^ b(>ing unuiterrupted 

 to beyond the middle, where there is a truncate or double- 

 (rusped oblique branch. The apex is forked and there are one 

 or two minute denticulations in the fork. The head is rather
