impressed) on the hinder disk, and with the first joint of its 

 funiculus perceptibly longer than the second. Judging from the 

 single specimen now before me, its sexual characters are likewise 

 different from those of L. clavatus ; for, although I cannot vouch 

 for the female, the male has its legs considerably more robust, 

 with the tibiae more pilose and the feet decidedly broader at their 

 base. Its posterior tibise, also, are not only wider but broadly 

 scooped-out internally from nearly the middle point to the ter- 

 minal angle, which last is extremely prominent*. 



The unique example (a male) from which the above descrip- 

 tion has been drawn out I detected lately amongst a quantity of 

 the Atlantis lamellipes which I had placed aside in a pill-box, 

 and which were captured by myself several years ago in the lofty 

 elevations of Madeira, principally at the Fanal.

This genus (which is identical with Cataphorticus of Jacq. 

 Duval) is closely allied to Trachjphloeus, with which, indeed, 

 until lately its members have been associated. It differs merely 

 in having the upper surface and sides of its head densely longi- 

 tudinally strigulose (a peculiarity of sculpture, however, which 

 is, of course, only perceptible when the scales are removed) ; in 

 its rostrum being shorter, with the lateral scrobs consequently 

 more abbreviated (and likewise more curved upwards), and with 

 the eyes a trifle more prominent ; in its antennae (which are im- 

 ])lanted rather behind the middle of its short scrobs, and there- 

 fore nearer to either eye) being rather longer and less incrassated, 

 the funiculus-joints being laxer inter se, and the first and second 

 of them more perceptibly elongated (though the former is less 

 evidently thickened than is the case in Trachyphloeus) ; in its 



* In some respects it approaches nearer to the L. morio; but, apart 

 from numerous other characters, its mucft narrower and apically-subdilated 

 rostrum, in conjunction with its less globose, more uneven, and much more 

 deeply and sparingly punctured prothorax, its more coarsely punctured ely- 

 tral striae, and the totally diflferent structure of its hinder male tibise, will 

 at once distinguish it from that insect.
