|tiiii(tiir('s ;ul)()iuiu<i the suture and a (louMc line at a little 

 (listaiK-e from it and are densely punetured except Ijeliiud the 

 scutc^Uuiu an(^l alonji the sutural niarj^in. The iikhIuhi is 

 coarsely ruj^ose. The ni'^tdstrnuDu and (djihnncn are shinin<_f, 

 with tlie sides rather strongly- punctured. The front tibin 

 is forked at the end and not very stout and the middle and 

 hind tibiie are armed with a strong lateral spine. 



cJ. Rather narrow and tapering behind, with broad liead 

 and })rothorax, the surface rather dull above and beneath. 

 'Fhe h('(td is Hat, iinely and densely granular, very broad in 

 front, with tlie front angles rounded, the eyes rather small, 

 the eanthus extending jtast the middle but not ])rominent, 

 the sides contracted beliind the eye.s. The cly])eal process 

 consists only of a short blunt tubercle and is extreimily 

 small. The pronotum is broad in front, hnely and densely 

 graiudar and opaque at the sides, very lightly in the middltr, 

 with the front angles rounded, the lateral margins feebly 

 curved to the shar])ly spiniform lateral angle. The elytra are 

 finely coriaceous and dull, excej)t in the sutural region, the 

 anterior ])art closely and Iinely ])unctured, the sides entirely 

 opacjue, the lateral margins a little flattened, the apices rather 

 nai'rowed. The nitntuta is a little hollowcHland bears scattered 

 j)unctures. The lower surface is dull, with a few [junctures 

 at the sides of the inekcsteniuni and ahdo)ne>i. The terminal 

 fork of the front tibia is strongly deflexed, the middle tibia 

 has a strong lateral spine and the hind tibia a minute one. 



Variation of the. male.— Variable phase. 'J'he mandibles 

 are a little longer than the head. Small examples have the 

 ui)|)(>r surface very dull and not very convTX. With increasing 

 size \\\(\ surface, esjK'cially of the j)ron(;tum, l)ecomes v(!ry 

 convex and less dull in the middle. The mandibles are 

 almost straight externally and l)ear rounded, bead-like teeth 

 at the iimer edge. In the smallest specimens there is cmly a 

 very small gap at the base between the closed mandibles. 

 'J'liis gap becomes progressively larger until only the anterior 

 halves are in contact but otherwise little change occurs even 

 in full-sized specimens, although the head is relatively much 

 broader. 



Constant phase. Tiie mandibles are slender, gently curved, 

 a little compressed laterally, smooth internally and externally, 

 with a small rounded basal process internally and a strong 

 erect curved antl jjointed process at the middle of the upper 

 edge. The tips are biHd.
