INSECTA MADERENSIA. 313 



238. Caulotrupis Chevrolatii, WoU. 



C. ovato-fusiformis seneus subuiticlus, prothorace pimctato, elytris nitidis obsolete substriato-pimc- 

 tatis, antennis elongatis pallido-ferrugineis, pedibus rufo-piceis. 

 Var. /3. obscurior, elj'trorum striis vix distiuctioribus. 

 Long. Corp. lin. l5-2. 



Habitat per rcgionem sylvaticam Maderse, sub lapidibus tmncisque arborum prolapsis, a 3000' usque 

 ad 6000' s. m., testate non infrequens. 



C. ovate-fusiform, seneous, and shining. Prothorax punctm-ed, though not quite so deeply so as in 

 the C. terebrans ; broadest in the middle, and distinctly narrowed behind. Scutellum more ap- 

 parent than in any of the other species (although excessively small). Elytra brilliant; lightly 

 punctate-striated, both the punctm-es and stride vanishing towards the outer margin and apex ; 

 and broadest about the middle. Antenna long, and pale-ferrxiginous. Legs rufo-piceous. 

 Var. /3. of an obscurer hue, and with the elytra somewhat more distinctly striated. 



In its sliining, brassy siu'face, and distinct prothoracic punctures, tlie present 

 Caiilotnqjis assimilates the C. terebrans. Nevertheless its larger size, more strictly 

 fusiform outline, posteriorly narrowed prothorax, and very lightly seidptured 

 elytra will at once separate it from that insect : whilst in its more evident scu- 

 telliun, which, though minute, is quite perceptible beneath a moderate lens, it 

 recedes from all the other species here described. Both the C. Chevrolatii and 

 opacus are less stalk-infesting in their habits than the allied forms, occurring 

 principally beneath stones and amongst chippings of wood in the lofty sylvan 

 districts. Diu'ing the summer of 1850 I captured it sparingly at the Lombo das 

 Vacas and the Lombo dos Pecegueiros ; as also, in tolerable abundance, in the 

 region of the Cruzinhas and Fanal. I have dedicated the species to M. Chevrolat 

 of Paris, whose valuable collection has afforded me much assistance, and whose 

 liberality in the loan and examination of specimens it gives me great pleasui'e to 

 record. 



239. Caulotrupis opacus, WoU. 



C. ovato-fusiformis subpiceo-seneus subopacus, prothorace subtilissime punctato, elytris obsolete sub- 



striato-punctatis, antennis elongatis pallido-fen-ugineis, pedibus rufo-piceis. 

 Long. Corp. liu. l|-2^. 



Habitat Maderam sylvaticam excelsam, in locis similibus ac prsecedens, sed iUo rarior. 



C. ovate-fusiform (though somewhat broader^ rather less convex, and more elliptical than the last 

 species), seneous with a slightly piceous tinge, and nearly opake. Prothorax most minutely 

 punctured ; broadest about the middle, and more or less narrowed behind. Elytra lightly punc- 

 tate-striated, both the punctures and striae (as in the C. Chevrolatii) vanishing towards the outer 

 margin and apex ; and broadest about the middle. Antenna long, and pale-ferruginous. Legs 

 nifo-piceous.
