Mr. T. V. Wollaston oii the CoUoptera of St. Helena. 19 



give a careful diagnosis of them, in the event, perhaps, of 

 their being identitied 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 w^j to differ from the pair now before me ; 

 whilst the fact that the species (the larva of which appears to 

 subsist within various seeds and berries which are used as 

 articles of food) has become naturalized, through the medium 

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

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

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

 island (as elsewhere) by indirect human agency. 



With the exception of the Notioxenus Bewickii^ the present 

 insect is considerably larger than any of the other members of 

 the Antii rib idee 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 strictly ^ewmc ones), 

 it may be further recognized by its compact thickened body 

 and short-oval outline, and by its brownish piceous surface 

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

 cinereous pubescence, the alternate elytral interstices having 

 additionally more or less obsolete indications of being obscurely 

 tessellated, which, however, is sometimes scarcely traceable. 

 Its eyes are large and prominent, its antennae 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.
