INSECTA MADERENSIA. 53 



lateral margins generally obscurely and narrowly rufescent ; a little narrowed towards the base, 

 where it is coarsely punctured and with a distinct fovea on either side; the hinder angles almost 

 right angles. Elytra somewhat parallel- ovate, deeply striated, the stripe being sometimes very 

 obscurely punctate, the interstices impunctate ; a little excavated at the apex, and each with a 

 very minutely impressed point, on the third interstice, behind. Femora usually dark : tibia at 

 base ferruginous ; their apex, and the tarsi, more or less rufo-piceous, or piceous. Antennte 

 fuscous, with the base bright rufo-ferruginous. 



The H. distinguendus is very closely allied to the common European S. ceneus, 

 and, although easily separable from it when in its normal state, yet the frequent 

 occurrence of connecting- Links between the two would seem to imply that it may 

 perhaps, in reality, be biit a local variety of that species. Still, it is usually 

 acknowledged to be distinct, and as such therefore I would retain it, more espe- 

 cially since the Madeu'an specimens are in their general aspect exceedingly typical 

 ones. It differs from the K. (enetis in having its elytra only just perceptibly ex- 

 cavated at their apex, and in theii- submarginal interstices beiag unpunctm-ed and 

 almost free from pubescence, in its hinder prothoracic angles being less obtuse, in 

 the prothorax itself being more deeply punctured, and foveolated, towards the 

 base, and by its femora being for the most part darkly coloured, — whereas in the 

 JS. ceneus it is the tendency of the legs to be altogether pale. It is a common 

 insect throughout Madeii-a, occui-ring beneath stones at nearly all elevations ; and 

 in Porto Santo it is even more abundant still, where I have at times observed it 

 in the low sandy vineyards behind the sea-beach in the greatest profusion. It is 

 found in most parts of central and southern Europe, and is recorded by Dejean as 

 having been brought even from the Brazils.
