INSECTA MADERENSIA. 165 



L. long, narrow, and somewhat cylindrical, piceous with a slightly rufescent, or rosy tinge, subopake, 

 but almost free from pubescence. Head and prothorax convex : the former rather suddenly 

 shortened (or less convex) in front of the antcunse, exceedingly wide (at any rate in the male sex) 

 between the eyes (which are small, and placed at a considerable distance from the anterior edge 

 of the prothorax), and very rugosely punctured, — the punctures being somewhat confluent, or 

 vermiculate, causing the sculpture to be almost longitudinally strigulose; with the forehead much 

 produced, although transversely truncated, in front ; with a raised marginal stria, and a very 

 obscurely depressed central one down the disk. Prothorax long, most delicately and minutely 

 granulated, exceedingly wide in front and narrowed behind ; and with all the angles rounded or 

 obtuse; the extreme front margin a little paler, or rufescent. Elytra subcylindrical, likewise 

 most minutely granulated ; entire at their apex ; distinctly striated, and with the interstices 

 longitudinally (though very obscurely) punctured; with an ill-deSned and sufiiised patch at the 

 shoulder of each of a rosy or rufescent tinge. Antenna piceo-ferruginous, short, moniliform (the 

 joints being subglobose), and robust (at any rate in the male, — and therefore probably, « for- 

 tiori, in the female), and becoming gradually a little thicker towards their apex. Femora rufo- 

 picescent : tibia piceo-ferruginous : tarsi testaceous. 



One of tlie most distinct and elegant of the Madeiran L(Bmo2Mcei. It may Ije 

 immediately known from all the other species hy its long, narrow, and subcylin- 

 drical form, by its excessively broad head and posteriorly-narrowed prothorax (from 

 the anterior edge of which its unusually small eyes are placed at a considerable 

 distance), by its deeply sculptured and longitudinally strigitlose forehead, and l)y 

 the dark colour of its body, — a suffused, rosy, or rufescent portion at the shoulder 

 of each of its elytra being alone paler. It is, apparently, extremely rare, the only 

 specimen (a male) which has hitherto come under my observation ha\-ing l^een 

 captured by myself at the edges of the Levada of the Ribeiro Erio, August 6, 1860. 



135. Lsemophlceiis Stenoides, Wall. (Tab. III. fig. 9.) 



L. antice subattenuatus rufo-ferrugineus opacus subtilissime subgranulatus, capite prothoraceque valde 

 rugulosis (sed vix punctatis), hoc elongato-subquadrato, angulis anticis obtusis, posticis leviter 

 exstantibus, elytris costato-striatis, pedibus rufo-testaceis. 

 Mas adhuc latet (foeminam tantum habeo, — cujus antennse sunt valde robustse et brevissimse) . 



Long, coi-p. lin. \\. 



Habitat Maderam; una cum L. axillari, d. 6 Aug. a.d. 1850, ad Ribeiro Frio a meipso captus. 



L. somewhat attenuated anteriorly, depressed, rufo-ferruginous, opake, free from pubescence, and 

 most minutely roughened, or very delicately subgranulated, all over. Head and prothorax (espe- 

 cially the former) greatly wrinkled, but not punctured : forehead much produced, though trans- 

 versely truncated, in front ; with a raised marginal stria, and with obscure indications of a 

 slightly elevated central one, which vanishes however both before and behind. Prothorax elon- 

 gate-subquadi-ate (being straight and very slightly narrowed behind) ; the anterior angles obtuse, 

 and the posterior ones a little prominent. Elytra entire at their apex ; and with about four very 

 distinctly raised strise on each. Antennce (at any rate in the female, of which I can alone speak)
