Judging ti-om the very short and imperfect " diagnosis " (so 

 called) of Fabricius, this large and uniformly black Tenebrionid 

 might possibly agree T\nth his Ildops morio from the West 

 Indies and other parts of Equatorial America ; but I think 

 that its sexual peculiarities do not tally with what little I can 

 gather elsewhere about those of that species ; for there seems 

 to be no difference in the relative length of the limbs, and 

 curvature of the tibije, between the males and females of the 

 insect from St. Helena. Yet, as in some of the other recorded 

 members of this singular group, there is the strange dissimi- 

 larity in the form of the cl^-peus (which is straightly truncate 

 in the females, but deeply scooped-out in the opposite sex), as 

 well as the perfect freedom from hairs of the front male tibia?, 

 whilst the female ones are (like the four hinder ones of that 

 sex.) fmnished internally, towards their apex, with a short 

 fulvescent pile. "Were it not for the greater length of its 

 limbs (particularly the antenna?), the present insect, in its 

 comparatively narrow elongated outline, and general contour, 

 would have much the j)}-imd facie aspect of a large Tenehrio ; 

 and it may be further recognized by its deep-black surface 

 being somewhat dulled, or clouded, in parts (especially to- 

 wards the sides and behind), as though by a kind of bloom j 

 by its prothorax being simply besprinkled on the disk with a 

 few large and remote punctures, and by its elyti-a (which are 

 gradually attenuated towards the apex) being regularly and 

 coarsely punctate-sulcate. Its head is branded with a little 

 foveolct on eitlier side in front, just within the angle of the 

 cly])cus ; and its prothorax (which is transversely impressed 

 across the greater jjortion of its base) has a somewhat similar 

 one, and almost equally minute, adjoining tlie extreme mar- 

 gin, at either end of the transverse impression.
