34 Mr. T. V. Wollaston on the Coleoptera of St. Helena. 



parce sed postice etiam parcius grossiusque punctato, utrinque 

 iutra augulos frontales foveola minuta impresso ; prothorace 

 transverso-subquadrato, antice paiilo latiore et leviter rotundato, 

 angulis anticis rotundate obtusis, posticis subproducte acutiiis- 

 culis, sensini margiiiato, convexo, iu disco punctis magnis remotis 

 parcissime irrorato, postice in medio transversim impresso, necnon 

 utrinque ad basin ipsissimam foveola parva brevi notato ; elytris 

 prothorace paulo latioribus, postice regulariter leuiterque attenu- 

 atis, grosse punctato-sulcatis ; antennis pedibusque longiusculis, 

 in utroque sexu similibus a^qualibus, 



3Ias, vix minor, clypeo antice profunde arcuato-emarginato, tibiis 

 anticis intus omnino calvis, posterioribus versus apicem paululum 

 fulvo-pubescentibus. 



Foem., vix major, clypeo antice recte truncate, tibiis intus versus 

 apicem (proesertim anticis) breviter fulvo-pubescentibus. 



Long. Corp. lin. 9g-10. 



Judging- from the very short and Imperfect " diagnosis " (so 

 called) of Fabricius, this large and uniformly black Tenebrionid 

 might possibly agree with his Ilelojis 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 tibiae, 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 clypeus (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 tibiae, 

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

 sex) furnished internally, towards their apex, with a short 

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

 limbs (particularly the antennae), the present insect, in its 

 comparatively narrow elongated outline, and general contour, 

 would have much the 2)rimd facie aspect of a large Te?iehn'o- 

 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, 

 by its prothorax being simply besprinkled on the disk with a 

 few large and remote punctures, and by its elytra (which are 

 gradually attenuated towards the apex) being regularly and 

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

 foveolet on either side in front, just within the angle of the 

 clypeus ; and its prothorax (which is transversely impressed 

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

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

 gin, at either end of the transverse impression.
