Xovdpus bifid us, u.sp. (Figs. 50, 51, 53.) 



cT. Of an unit'onn re(l(lisli-l)ic)\vn, except that the head and some 

 parts of the legs and of the prothoracic margins are black or 

 blackish. Under surface with long reddish hair, becoming 

 lineate in arrangement on the abdomen, pygidium and legs. 



Head small, with coarse punctures ; in front witli three 

 projections, a median one truncate at its tip, and a smaller 

 one about half way between the median one and each eye. With 

 a strong erect horn, slightly longer than head is wide, and dis- 

 tinctly bifid at its apex, punctured as the rest of head at its 

 lower front, but the punctures decreasing in size upwards and 

 becoming very small at the apices. Prothorav about once and 

 one-third as wide as long ; with an excavation occupying about 

 one-half of its width, its hinder margin evenly curved, but sides 

 almost straight ; slightly notched behind head ; with rather 

 dense and shallow punctures, somewhat sparser, in excavation than 

 elsewhere. Scutellum with punctures only about base. Elytra 

 slightly narrower than widest part of prothorax ; with punctures 

 somewhat as on prothorax, but sparser and more irregular, and 

 in places in feeble geminate striae ; with snialler punctures 

 irregularly distributed, and becoming fairly numerous towards 

 sides. Abdumen with dense punctures at sides, but becoming 

 sparse and seriate across middle. Leys stout ; front tibiae with 

 three strong teeth, the front one rounded, the others somewhat 

 larger and triangular, spur just passing base of front tooth, 

 and about tlie length of claw joint ; middle tibiae with two semi- 

 circular ridges tipped with stout setae, in addition to the strong 

 apical ridge, with two stout spurs of uneven size, the shorter 

 as long as the first tarsal joint, the other as long as the two 

 first tarsal joints combined ; hind tibiae with somewhat similar 

 ridges and spurs. Length 25, width 14 mm. 



?. Dill'ers in having a much smaller cephalic horn, divided at 

 the tip but with parallel sides, and the punctures coarser. The 

 prothorax is nowhere quite as wide as the greatest width of elytra, 

 the excavation is rej^resented by a veiy small frontal impression, 

 scarcely visible from some directions, the punctures are more 

 numerous and slightly larger. The elytra have rather more 

 distinct punctures. Ihe abdomen has rather numerous punc-
