Sitona lineata, Steph. III. Brit. Ent. iv. 135 (1831). 



lineatus, Sclion. Gen. et Spec. Cure. ii. 109 (1834). 



Habitat in TMadera Portixque Sancto, liinc inde sat vulgaris, ex Europ^ forsan introducta. 



S. elongate and parallel, black, and densely clothed vsdth fulvous and cinereo-fulvous scales above, and 

 with pale cinereous ones beneath. Rostrum as in the S. canibrica, except that it is flatter and 

 less sculptured above, and with the medial canal narrower and less deep. Erjes nearly round, 

 and less prominent than in any of the preceding species. Prothorax finely and very closely 

 punctulated ; widest a little behind the middle ; with its front margin slightly raised ; and with 

 three more or less distinct longitudinal lines composed of the paler scales. Elytra punctate- 

 striated, and with the interstices flattened, — the scales of the alternate ones being more or less 

 evidently paler. Antenna, tibia and tarsi pale ferruginous, — the legs being of subequal length. 



An insect which ahoimds thronghont every portion of Evirope, — from where 

 indeed it has j)robahly been introduced into these islands. It is not very common 

 in Madeii'a, occui'ring principally at low elevations and in the neighbourhood of 

 Funchal, — where I have constantly observed it during the spring months, espe- 

 cially in the Rev. E,. T. Lowe's garden at the Levada. It is occasionally however 

 to be met Tvath at higher elevations, since in the simimer of 1850 I took it 

 sparingly at the Hibeu'o Prio. I have likewise captured it, behind the sea-beach, 

 in Porto Santo. It may be at once known by its parallel outline, by the light 

 brown scales with which it is clothed (the three prothoracic lines and the 

 alternate interstices of its elytra being alone slightly paler), and by its ferruginous 

 antennae, tibiae and feet. 



312. Sitona humeralis. 



S. subparallelo-elongata (antice subacuminata), squamuKs cinereis et infuscato-cinereis insequaliter 

 tecta, prothorace rugulose punctato angusto subconico (ad latera pone medium vix rotundato), 

 elytris leviter punctato-striatis, versus latera cinereo-variegatis sed in disco communi ssepius late 

 obscurioribus, antennis, tibiis tarsisque obscuro-ferrugineis.

Sitones promptus, Eedt. Fna Aiistr. 451 (1849). 



Habitat in locis similibus ac prsecedens, sed paulo rarior : in Portu Sancto tamen prsedominat, quii 

 mense Aprili a.d. 1848 plurima specimina per oram maritimam collegi. 



S. about the same size as (or a little smaller than) the S. lineata, but rather less parallel (being 

 slightly acuminated anteriorly), black, and densely, though unequally, clothed with cinereous and 

 brownish-cinereous scales above, — but with uniformly cinereous ones beneath. Rostrum rather 

 narrower than that of the -S. lineata, and with its medial channel (like that of the S. cambrica)
