Habitat in domibus mercatorumque repositoriis Maderse ubique v'ulgare, ex alienis certe introductum. 



T. linear-elongate (being of nearly the same breadth throughout) and narrow, dull rufo-ferruginous, 

 nearly opake, and depressed. Head and prothorax veiy closely puuctulated (but not quite so 

 finely as in tlie Cerandria curnuta) ; the former with the forehead rounded, a Uttle expanded and 

 elevated before the eyes, and depressed in front ; the latter transverse-quadrate (being scarcely 

 at all widened anteriorly), with the posterior angles less defined than those of the last insect, and 

 with a shallow longitudinal fovea on either side behind. Elytra with slightly elevated striae, very 

 apparent towards the sides, but evanescent on their common disk ; the interstices with a usually 

 double series of minute punctures down each. Legs, and (especially) the club of the antenna, of 

 a rather paler colour than the rest of the surface. 



A universal insect throughout the ciTilized world, being, like the last one, 

 liable to dissemination with various articles of commerce. It is moreover less 

 exclusively granivorous in its habits, feeding occasionally on di'ied animal sub- 

 stances (like TroQosita and some of the Do'inestkhe), and being at times A'ery 

 destructive to collections of insects, — residing in the cre\ices of the boxes, and 

 devouring not only the cement by which they are held together, but even the 

 specimens themselves. It is abundant in Madeu'a, especially about dwellings and 

 warehouses in and near Funchal ; and it may be often observed crawHng up the 

 walls of the buildings, in company with the Loimophlceus pusillus, Cryptophagus 

 (iffinis and the Sifophilus Or y zee, in considerable nimibers.
