Chestnut, with the apex of the elytra paler or ochraceous 

 and a band immediately before the lighter space darker chest- 

 nut, and here and there spattered with whitish and ochreous 

 scales ; linear-elongate, narrow, subcylindric ; the head exca- 

 vated in front, clothed with yellowish-white hairs. Prothorax 

 broadest in front, unequal, with depressions on the sides and 

 in front of the scutellum, and with two rather large tubercles 

 near the anterior margin ; sides sinuate, covered with numerous 

 transverse fine granulous strias, giving the effect of punctures. 

 Scutellum black, deeply sunk in the elytra, nearly vertical, 

 elongate, with the apex rounded and somewhat knobbed.- 

 Elytra narrowly linear, granulously thickly finely punctate, 

 obsoletely costate, clothed with ochraceous hairs on each side 

 of the scutellum, and with two interrupted slender bands of 

 white scales, the anterior one a little behind the scutellum, 

 confined to one or two small spots of white hairs or scales, the 

 posterior immediately in front of the darker band of chestnut, 

 which is just before the pale apex ; the anterior margin of this 

 pale apex is clothed with ochreous-yellow scales, which gives 

 a light border to each side of the darker band, making it ap- 

 pear darker in colour than it really is. The antennaj and legs 

 chestnut. Underside of body brown, except the sides and 

 margins of the sutures and segments of the abdomen, which 

 are chestnut. 



The above description was written before I saw that given in 

 Dr. Cand^ze's ^ Elaterides Nouveaux,' and I have allowed it 

 to stand, as perhaps useful to some as a second description, 

 and at all events convenient to those who may not possess the 

 Supplement to Dr. Cand^ze's ^ Elateridas,' which has been 

 published under the above title in the M^moires of the Roy. 

 Acad, of Brussels. 



This is another instance of the occurrence of Brazilian forms 

 at Old Calabar. No Dilohotarsus has previously been found 

 out of South America ; and as it is a genus of remarkable 

 characters and striking form, there is no room for referring its 

 affinity to some other type which may occur in the Old World. 

 It is what I should term a crucial example of the occurrence 

 of a purely American form in Africa proper. But another 

 noteworthy circumstance is, that this species is not (as is the 

 case with most of the strictly American forms which we have
