414 Mr. T. V. Wollaston on Madeiran Coleoptera. 



the above structural details of it in full, because I believe they 

 have never yet been published. I need scarcely add, however, 

 that they are drawn out entirely from the insect described below ; 

 consequently if it should happen that the A. f armaria is not 

 strictly congeneric with the species which have been usually 

 regarded as Adelince, it follows as a necessity (if indeed ray con- 

 clusion is correct, that the group has not yet been characterized) 

 that the latter will eventually require a new name. I would 

 call attention to this, because, having lately had an opportunity 

 of examining superficially several representatives of Adelina in 

 the Collection of the British Museum, they appeared to me 

 to offer sufficient external diff"erences from the Madeiran insect 

 to warrant a suspicion that a careful dissection of them might 

 perhaps bring structural characters to light distinct from those 

 from which the above diagnosis has been compiled. Neverthe- 

 less, since this is only a conjecture, and since it is the opinion 

 of my friend Dr. Schaum of Berlin that the JMadeiran beetle is 

 truly an Adelina, I have not hesitated to regard it as such, and 

 have drawn out my generic details from it accordingly. 



Adelina farinaria, n. sp. 



A. oblonga, rufo-picea, nitida, valde depressa ; capite prothoraceque 

 confertim leviter punctulatis, hoc transverse, postice foveolis dua- 

 bus brevibus longitudinaliter impresso, per marginem posticum 

 sinuate ; elytris puuetato-striatis, interstitiis subtilissime punctu- 

 latis. 



Long. corp. liu. 3. 



Variat (immatura) colore pallido-ferrugineo. 



A. oblong and greatly depressed, shining and glabrous, and 

 (when mature) of a bright rufo-piceous hue; when immature, 

 pale ferruginous. Head and prothorax closely and rather finely 

 punctulated : the clypeus of the former uneven, and a good 

 deal thickened and elevated about its margin, especially over the 

 insertion of the antennae : the latter squarish-transverse, with 

 the sides a little rounded, and impressed behind with two very 

 short and rather obscure longitudinal foveae ; the portion between 

 these foveas a little lobed (or produced backwards in front of the 

 scutellum), causing the posterior margin to be slightly sinuated. 

 Ehjtra rather lightly punctate-striated, and with the interstices 

 most minutely and somewhat sparingly punctulated. Limbs 

 usually concolorous with the rest of the surface. 



As already implied in my observations under Rhyzopertha 

 bifoveolata, the present insect can only be admitted into the 

 Madeiran Catalogue as an imported one. Nevertheless it falls 

 into the same category with many others (such^as Cerandria,
