160 INSECTA MADERENSIA. 



striated upon the disk, — the strhe vanishing towards the base and apex, especially the latter ; 

 testaceous, with the suture, the strije, and occasionally also the external margins, darker. 

 Antenna at base ferruginous ; and with their apical joint very distinctly tubercled at its extremity. 

 Legs testaceous. 

 Male, with the antennae exceedingly long ; and with two large punctures, or rounded fovese (rarely 

 evanescent), placed longitudinally on either side of the hinder prothoracic disk. 



A large and most beautiful Lccmophlcc)(s, and one which recedes in many ini- 

 jjortant particulars from the other members of the genus here described, — its dark 

 and comparatively variegated surface, and the great length of its antemiae, in con- 

 junction with the two abbreviated polished spaces at the anterior margin, and the 

 four rounded impressions (in the male sex) on the hinder disk of its prothorax, 

 giWng it a character essentially its own. It is, apparently, very rare, and confined 

 to intermediate altitudes within the sylvan districts. I have taken it during the 

 summer months, on more than one occasion, from beneath the bark of the Spanish 

 chestnuts in Senhor Louiz Acciaioly's vineyard at Santa Anna ; and, likewise, in 

 the Boa Ventura, on the 18th of February 1849. 



129. Lsemophloeus graniilatus, WuU. 



Ij. rufo-ferrugineus granulatus opacus, capite prothoraceque parce leviter punctatis, hoc elongato- 

 subquadrato angulis subaequaliter exstantibus, elytris striatis ad apicem leviter truncatis, pedibus 

 rufo-testaceis. 

 Mas, antennis longioribus. 



Long. Corp. lin. 1-1^. 



Habitat per regionem Maderse sylvaticam, non infrequens : in convalle Boa Ventura dicta mense 

 Februario, necnon tempore sestivo in castanetis Sancta Annie, sat copiose observavi. 



Ij. exceedingly depressed, parallel, rufo-ferruginous, opake, and almost free from pubescence. Head 

 and prothorax very closely granulated, and with fine and very shallow punctures intermixed : 

 forehead with the anterior edge truncated and hollowed out immediately in front of the antennae; 

 with a raised marginal stria, and a very distinctly impressed central one down the disk. Prothorax 

 elongate-subquadrate, and very slightly narrowed behind; with the anterior and posterior angles 

 almost equally ])roniinent (the former perhaps, if anything, being rather the more so). Elytra 

 rather long, similarly granulated with the head and ])rothorax ; much less truncated behind than 

 those of the last species; striated, — the subsutural strise being generally obsolete in front. 

 Antenna longer in the males than in the females (longer, in both sexes, than those of any of the 

 following species, but shorter than those of the L. Donncioides) ; and with their apical joint very 

 distinctly tubercled at its extremity. Legs rufo-testaceous. 



In their opake, granulated, and almost unpubescent sm'faces, and in the com- 

 paratively great length of theu" antennaj (the apical articulation of which is shrunk 

 and suddenly acuminated at its extremity, — so as to resemble a separate tubercle, 

 or even an additional joint), as well as in the broad truncation (or somewhat
