INSECTA MADERENSIA. 447 



341. Longitarsus nervosus, Woll. 



Ij. elongato-ovatus convexus nitidus testaceus, elytris pallidioribus, femorum posticorum apice nigro- 

 piceo, antennis apicern versus infuscatis. 

 Va?: /3. paulo major, elytris minus evidenter punctulatis vix obscurioribus subtranslucidis. 

 Long. Corp. lin. 1^-1^^. 



Habitat in locis similibus Maderae Portiisque Sancti ac prsecedens, sed illo copiosior : var. /3. sola ad 

 Desertam Grandem solam pertinet, qua Maio exeunte a.d. 1850 plurima specimina cepi. 



Ij. elongate-ovate, convex, shining, and testaceous. Elytra slightly paler than the head and pro- 

 thorax ; and minutely, but distinctly, punctulated. Meso- and metu-thoraces beneath, and the 

 apical half of the two hinder femora, piceous-black. Antenna at apex infuscated. 

 Var. /3. rather larger, with the elytra less evidently punctulated and not quite so pale, — being of a 

 more cUluted, cloudy, or semitransparent hue. 



Not an vmcommon insect at rather low, or intermediate altitudes, occurring 

 in most of the islands of the group. I have taken it near Funchal, dm*ing the 

 autumn and spring, principally in the Ribeira de Santa Luzia and at the Cm'ral 

 das E-omeiras ; on the grassy slopes of Porto Santo in April ; and on the Dezerta 

 Grande in May. It may be kno^vn from the rest of the Longitarsi here described 

 by its uniformly testaceous hue, — the only dark portions visible on its upper 

 surface (apart from the eyes) being the apices of its two hinder femora; and thus, 

 whilst its actual colom* is not so pallid as that of the L. Intescens, yet its entire 

 freedom from black markings above (even its head being pale) gives it a peculiar 

 character, which it is impossible to mistake. Its body beneath, moreover, is lighter 

 than in the other species, — the meso- and meta-sterna being alone universally 

 dark. The specimens from the Dezerta Grande {var. (3.) are a trifle larger and 

 duskier than those from Madeira and Porto Santo, and not quite so distinctly 

 punctulated : nevertheless they are clearly but a local form, and without any 

 claim to specific isolation.

342. Longitarsus nubigena, Wall. 



It. parvus elongato-ovatus convexus subnitidus ferrugineus, capite, femorumque posticorum apice 



picescentibus, elytris minus rufescentibus subseriatim punctatis.

Habitat in montibus IMaderse borealis, rarissimus : specimina duo sola detexi, unum sc. ad summam

 Pecegueiros, mense Julio a.d. 1850 capta. 



Ii. small, elongate-ovate, convex, very slightly shining, and of a dull reddish-ferruginous. Head 

 slightly dusky, being of a somewhat more rufo-picescent hue than the prothorax. Elytra a little
