322 INSECTA MADERENSIA. 



broad and convex, — the alternate ones being considerably elevated in front, and that on either 

 side of the suture with a longitudinal row of impressed points. Antenna and legs concolorous 

 with, or a little paler than, the rest of the insect. 



Male, with the rostrum rather more coarsely punctured, and with its base more perceptibly keeled. 



Female, with the rostrum more lightly punctured, and with its base scarcely, if at all, keeled. 



Readily distinguislicd from the following by its somewliat larger size, mfo-ferru- 

 ginous hue, and by its altogether different sculptm-e, — its prothoracic pvinctm'es 

 being deep, oblong and comparatively remote, whilst its elytra are c;*e??a^e-striated, 

 with their interstices wide, and the alternate ones much elevated in fi-ont. It is a 

 universal insect throughout Europe, and indeed tlu'oughout the greater portion of 

 the ci\dlized world, being liable to transmission with corn and other grain. It is, 

 apparently, however less common in southern latitudes than ia temperate and 

 northern ones ; and hence in Madeu*a it is rarer than the S. OryzcB, which aboimds 

 in nearly all the houses and shops of Funchal. The present species is, never- 

 theless, occasionally but too plentiful in granaries; and it may be constantly 

 observed crawling on the walls, both external and internal, in and about the 



villages and to^vns. 



246. Sitophilus Oryzae. 



S. nigi-o-piceus subopacus, prothorace profunde confertim punctato (punctis rotundatis), elytris pro- 



funde punctato-striatis, singulo macuUs duabus rufesccntibus ornato, antennis pedibusque rufo- 



ferrugineis. 



Mas, rostro carinato et profunde punctato. 



Fam., rostro basi tantum carinato profunde punctato (apicem versus laeviore nitido).

Habitat inter semina Onjza et Teee, vel super muros domuum Funchalensium, — una cum prsecedente 

 degens, sed illo multo frcquentior. 



S. dark-piceous, and almost opake. Prothorax very deeply and thickly punctured, — the punctures 

 being round, and much closer together than those of the last species. Elytra deeply punctate- 

 striated, with the interstices narrow and raised ; each with a rufescent patch near the shoulder, 

 and another towards the apex. Antenna and legs rufo-feiTuginous. 



Male, with the rostrum keeled and coarsely punctured. 



Female, with the rostrum keeled and coarsely punctured at its extreme base only, — being uukeeled, 

 more lightly punctured, and shining towards its apex. 



Its darker colour, and nearly opake, differently sculptured surface, ui conjimc- 

 tion with the four rufescent patches of its elytra, will, prima facie, separate the 

 present Sitophilus from the preceding one. As already stated, it is by far the 

 commoner of the two in Madeii-a, occurring in nearly all the houses, — and occa-
