Mr. T. V. Wollastou on the Coleoptera of St. Helena. V.) 



give a careful diagnosis of tliein, in the event, )Krliaps, of 

 their being identified hereafter with some cognate form. The 

 insect, however, is evidently a variable one ; and there are 

 individuals in the British Museum, bearing the label " coffece^'' 

 which seem in no way to differ from the pair now before me ; 

 whilst the fact that the species (the larva of which a})peai-s to 

 subsist within various seeds and berries which are used as 

 articles of food) has become naturalized, througli the medium 

 of commerce, in most of the warmer countries of the civilized 

 world would go far to render it probable that tlie St. -Helena 

 one is the true fasciculatus^ and has been established in the 

 ishand (as elsewhere) by indirect human agency. 



With the exception of the Notioxenus Bewickii^ the present 

 insect is considerably h\rger than any of the other members of 

 X\iQ. Anthrihldd' hitherto detected in St. Helena; and, apart 

 from the greatly elongated first joint of its feet, and the fact 

 of its transverse prothoracic keel being removed to the extreme 

 base (so as to form a mere elevated margin to the pronotum), 

 and then produced, at right angles, to about midway along the 

 lateral edge (characters which are more air'mtXj (jeneric ones), 

 it may be further recognized by its compact thickened body 

 and short-oval outline, and by its brownish piceous sui-face 

 being clothed with an abbreviated, dccmiibent, scale-like, 

 cinereous pubescence, the alternate elytral interstices having 

 additionally more or less obsolete indications of being obscm-ely 

 tessellated, which, however, is sometimes scarcely traceable. 

 Its eyes are large and prominent, its antennaj rufo-testaceous 

 and extremely slender, and its surface, when the pubescence 

 is removed, will be seen to be nearly opaque, and closely and 

 coarsely sculptured.
